J2EE deployment descriptors

 
 
Every J2EE application module must include an XML based deployment descriptor that provide configuration information for the asset as well as defining relationships to other components.

There are two types of deployments descriptors:
  • vendor neutral deployment descriptors (a.k.a deployment descriptors)
  • vendor specific deployment descriptor (a.k.a deployment plans)
Deployment descriptors are necessary but are not always sufficient to deploy an asset on your server.
Deployment plans provides additional information to map declared resources names, ejb names, security roles, JMS roles (if any) to actual resources in the server. The deployment plans also contain specific server settings and configurations.

        res-sharing-scope ? The res-sharing-scope element specifies whether connections obtained through the given resource manager connection factory reference can be shared. The value of this element, if specified, must be one of the two following:

<res-sharing-scope>Shareable</res-sharing-scope>
<res-sharing-scope>Unshareable</res-sharing-scope>

The default value is Shareable.
      resource-env-ref * The resource-env-ref element contains a declaration of an enterprise bean's reference to an administered object associated with a resource in the enterprise bean's environment. It consists of an optional description, the resource environment reference name, and an indication of the resource environment reference type expected by the enterprise bean code.

Example:

<resource-env-ref>
   <resource-env-ref-name>jms/StockQueue</resource-env-ref-name>
   <resource-env-ref-type>javax.jms.Queue</resource-env-ref-type>
</resource-env-ref>
        description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
        resource-env-ref-name 1 The resource-env-ref-name element specifies the name of a resource environment reference; its value is the environment entry name used in the enterprise bean code. The name is a JNDI name relative to the java:comp/env context and must be unique within an enterprise bean.
        resource-env-ref-type 1 The resource-env-ref-type element specifies the type of a resource environment reference. It is the fully qualified name of a Java language class or interface.
***** END SESSION, ENTITY OR MESSAGE-DRIVEN ELEMENT *****

  relationships ? The relationships element describes the relationships in which entity beans with container-managed persistence participate. The relationships element contains an optional description; and a list of ejb-relation elements, which specify the container managed relationships.
    description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
    ejb-relation + The ejb-relation element describes a relationship between two entity beans with container-managed persistence. An ejb-relation element contains a description; an optional ejb-relation-name element; and exactly two relationship role declarations, defined by the ejb-relationship-role elements. The name of the relationship, if specified, is unique within the ejb-jar file.
      description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
      ejb-relation-name ? The ejb-relation-name element provides a unique name for a relationship.
      ejb-relationship-role 1 The ejb-relationship-role element describes a role within a relationship. There are two roles in each relationship.

The ejb-relationship-role element contains an optional description; an optional name for the relationship role; a specification of the multiplicity of the role; an optional specification of cascade-delete functionality for the role; the role source; and a declaration of the cmr-field, if any, by means of which the other side of the relationship is accessed from the perspective of the role source.

The multiplicity and role-source element are mandatory.

The relationship-role-source element designates an entity bean by means of an ejb-name element. For bidirectional relationships, both roles of a relationship must declare a relationship-role-source element that specifies a cmr-field in terms of which the relationship is accessed. The lack of a cmr-field element in an ejb-relationship-role specifies that the relationship is unidirectional in navigability and the entity bean that participates in the relationship is "not aware" of the relationship.

Example:

<ejb-relation>
   <ejb-relation-name>Product-LineItem</ejb-relation-name>
   <ejb-relationship-role>
      <ejb-relationship-role-name>
         product-has-lineitems
      </ejb-relationship-role-name>
      <multiplicity>One</multiplicity>
      <relationship-role-source>
         <ejb-name>ProductEJB</ejb-name>
      </relationship-role-source>
   </ejb-relationship-role>
      ejb-relationship-role 1 Same as above.
        description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
        ejb-relationship-role-name ? The ejb-relationship-role-name element defines a name for a role that is unique within an ejb-relation. Different relationships can use the same name for a role.
        multiplicity 1 The multiplicity element describes the multiplicity of the role that participates in a relation.

The multiplicity element must be one of the two following:

<multiplicity>One</multiplicity>
<multiplicity>Many</multiplicity>
        cascade-delete ? This empty element specifies that, within a particular relationship, the lifetime of one or more entity beans is dependent upon the lifetime of another entity bean. The cascade-delete element can only be specified for an ejb-relationship-role element contained in an ejb-relation element in which the other ejb-relationship-role element specifies a multiplicity of One.
        relationship-role-source 1 The ejb-relationship-role-name element defines a name for a role that is unique within an ejb-relation. Different relationships can use the same name for a role.
          description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
          ejb-name 1 The ejb-name element specifies an enterprise bean's name. This name is assigned by the ejb-jar file producer to name the enterprise bean in the ejb-jar file's deployment descriptor. The name must be unique among the names of the enterprise beans in the same ejb-jar file.

There is no architected relationship between the ejb-name in the deployment descriptor and the JNDI name that the Deployer will assign to the enterprise bean's home.

The name for an entity bean with cmp-version 2.x must conform to the lexical rules for an NMTOKEN. The name for an entity bean with cmp-version 2.x must not be a reserved literal in EJB QL.

Example:

<ejb-name>EmployeeService</ejb-name>
        cmr-field ? The cmr-field element describes the bean provider's view of a relationship. It consists of an optional description, and the name and the class type of a field in the source of a role of a relationship. The cmr-field-name element corresponds to the name used for the get and set accessor methods for the relationship. The cmr-field-type element is used only for collection-valued cmr-fields. It specifies the type of the collection that is used.
          description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
          cmr-field-name 1 The cmr-field-name element specifies the name of a logical relationship field in the entity bean class. The name of the cmr-field must begin with a lowercase letter. This field is accessed by methods whose names consist of the name of the field specified by cmr-field-name in which the first letter is uppercased, prefixed by "get" or "set".
          cmr-field-type ? The cmr-field-type element specifies the class of a collection-valued logical relationship field in the entity bean class. The value of the cmr-field-type element must be either: java.util.Collection or java.util.Set.
  assembly-descriptor ? The assembly-descriptor element contains application-assembly information.

The application-assembly information consists of the following parts: the definition of security roles, the definition of method permissions, the definition of transaction attributes for enterprise beans with container-managed transaction demarcation and a list of methods to be excluded from being invoked.

All the parts are optional in the sense that they are omitted if the lists represented by them are empty.

Providing an assembly-descriptor in the deployment descriptor is optional for the ejb-jar file producer.
    security-role * The security-role element contains the definition of a security role. The definition consists of an optional description of the security role, and the security role name.

Example:

<security-role>
   <description>
      This role includes all employees who are authorized
      to access the employee service application.
   </description>
   <role-name>employee</role-name>
</security-role>
      description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
      role-name 1 The role-name element contains the name of a security role.

The name must conform to the lexical rules for an NMTOKEN.
    method-permission * The method-permission element specifies that one or more security roles are allowed to invoke one or more enterprise bean methods. The method-permission element consists of an optional description, a list of security role names or an indicator to state that the method is unchecked for authorization, and a list of method elements.

The security roles used in the method-permission element must be defined in the security-role elements of the deployment descriptor, and the methods must be methods defined in the enterprise bean's component and/or home interfaces.
      description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
      role-name |
unchecked
+
1
The role-name element contains the name of a security role. The name must conform to the lexical rules for an NMTOKEN.

The unchecked element specifies that a method is not checked for authorization by the container prior to invocation of the method.
      method + The method element is used to denote a method of an enterprise bean's home or component interface, or, in the case of a message-driven bean, the bean's onMessage method, or a set of methods. The ejb-name element must be the name of one of the enterprise beans declared in the deployment descriptor; the optional method-intf element allows to distinguish between a method with the same signature that is multiply defined across in both the home and component interfaces; the method-name element specifies the method name; and the optional method-params elements identify a single method among multiple methods with an overloaded method name.

There are three possible styles of the method element syntax:

1.
<method>
   <ejb-name>EJBNAME</ejb-name>
   <method-name>*</method-name>
</method>

This style is used to refer to all the methods of the specified enterprise bean's home and component interfaces.

2.
<method>
   <ejb-name>EJBNAME</ejb-name>
   <method-name>METHOD</method-name>
</method>>

This style is used to refer to the specified method of the specified enterprise bean. If there are multiple methods with the same overloaded name, the element of this style refers to all the methods with the overloaded name.

3.
<method>
   <ejb-name>EJBNAME</ejb-name>
   <method-name>METHOD</method-name>
   <method-params>
      <method-param>PARAM-1</method-param>
      <method-param>PARAM-2</method-param>
      ...
      <method-param>PARAM-n</method-param>
    </method-params>
<method>

This style is used to refer to a single method within a set of methods with an overloaded name. PARAM-1 through PARAM-n are the fully-qualified Java types of the method's input parameters (if the method has no input arguments, the method-params element contains no method-param elements). Arrays are specified by the array element's type, followed by one or more pair of square brackets (e.g. int[ ][ ]). If there are multiple methods with the same overloaded name, this style refers to all of the overloaded methods.

Examples:

Style 1: The following method element refers to all the methods of the EmployeeService bean's home and component interfaces:

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-name>*</method-name>
</method>

Style 2: The following method element refers to all the create methods of the EmployeeService bean's home interface(s).

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-name>create</method-name>
</method>

Style 3: The following method element refers to the
create(String firstName, String LastName) method of the
EmployeeService bean's home interface(s).

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-name>create</method-name>
   <method-params>
      <method-param>java.lang.String</method-param>
      <method-param>java.lang.String</method-param>
   </method-params>
</method>

The following example illustrates a Style 3 element with more complex parameter types. The method foobar(char s, int i, int[ ] iar, mypackage.MyClass mycl, mypackage.MyClass[ ][ ] myclaar) would be specified as:

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-name>foobar</method-name>
   <method-params>
      <method-param>char</method-param>
      <method-param>int</method-param>
      <method-param>int[ ]</method-param>
      <method-param>mypackage.MyClass</method-param>
      <method-param>mypackage.MyClass[ ][ ]</method-param>
   </method-params>
</method>

The optional method-intf element can be used when it becomes necessary to differentiate between a method that is multiply defined across the enterprise bean's home and component interfaces with the same name and signature.

For example, the method element

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-intf>Remote</method-intf>
   <method-name>create</method-name>
   <method-params>
      <method-param>java.lang.String</method-param>
      <method-param>java.lang.String</method-param>
   </method-params>
</method>

can be used to differentiate the create(String, String) method defined in the remote interface from the create(String, String) method defined in the remote home interface, which would be defined as

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-intf>Home</method-intf>
   <method-name>create</method-name>
   <method-params>
      <method-param>java.lang.String</method-param>
      <method-param>java.lang.String</method-param>
   </method-params>
</method>

and the create method that is defined in the local home interface which would be defined as

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-intf>LocalHome</method-intf>
   <method-name>create</method-name>
   <method-params>
      <method-param>java.lang.String</method-param>
      <method-param>java.lang.String</method-param>
   </method-params>
</method>

The method-intf element can be used with all three Styles of the method element usage. For example, the following method element example could be used to refer to all the methods of the EmployeeService bean's remote home interface.

<method>
   <ejb-name>EmployeeService</ejb-name>
   <method-intf>Home</method-intf>
   <method-name>*</method-name>
</method>
        description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
        ejb-name 1 The ejb-name element specifies an enterprise bean's name. This name is assigned by the ejb-jar file producer to name the enterprise bean in the ejb-jar file's deployment descriptor. The name must be unique among the names of the enterprise beans in the same ejb-jar file.

There is no architected relationship between the ejb-name in the deployment descriptor and the JNDI name that the Deployer will assign to the enterprise bean's home.

The name for an entity bean with cmp-version 2.x must conform to the lexical rules for an NMTOKEN. The name for an entity bean with cmp-version 2.x must not be a reserved literal in EJB QL.

Example:

<ejb-name>EmployeeService</ejb-name>
        method-intf ? The method-intf element allows a method element to differentiate between the methods with the same name and signature that are multiply defined across the component and home interfaces (e.g, in both an enterprise bean's remote and local interfaces; in both an enterprise bean's home and remote interfaces, etc.)

The method-intf element must be one of the following:

<method-intf>Home</method-intf>
<method-intf>Remote</method-intf>
<method-intf>LocalHome</method-intf>
<method-intf>Local</method-intf>
        method-name 1 The method-name element contains a name of an enterprise bean method or the asterisk (*) character. The asterisk is used when the element denotes all the methods of an enterprise bean's component and home interfaces.
        method-params ? The method-params element contains a list of the fully-qualified Java type names of the method parameters.
          method-param * The method-param element contains the fully-qualified Java type name of a method parameter.
    container-transaction * The container-transaction element specifies how the container must manage transaction scopes for the enterprise bean's method invocations. The element consists of an optional description, a list of method elements, and a transaction attribute. The transaction attribute is to be applied to all the specified methods.
      description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
      method + Same as <assembly-descriptor> <method-permission> <method>.
      trans-attribute 1 The trans-attribute element specifies how the container must manage the transaction boundaries when delegating a method invocation to an enterprise bean's business method.

The value of trans-attribute must be one of the following:

<trans-attribute>NotSupported</trans-attribute>
<trans-attribute>Supports</trans-attribute>
<trans-attribute>Required</trans-attribute>
<trans-attribute>RequiresNew</trans-attribute>
<trans-attribute>Mandatory</trans-attribute>
<trans-attribute>Never</trans-attribute>
    exclude-list ? The exclude list element specifies one or more methods which the Assembler marks to be uncallable.

If the method permission relation contains methods that are in the exclude list, the Deployer should consider those methods to be uncallable.
      description ? The description element is used to provide text describing the parent element. The description element should include any information that the enterprise bean ejb-jar file producer wants to provide to the consumer of the enterprise bean ejb-jar file (i.e., to the Deployer). Typically, the tools used by the enterprise bean ejb-jar file consumer will display the description when processing the parent element that contains the description.
      method + Same as <assembly-descriptor> <method-permission> <method>.
  ejb-client-jar ? The optional ejb-client-jar element specifies a JAR file that contains the class files necessary for a client program to access the enterprise beans in the ejb-jar file.

<ejb-client-jar>employee_service_client.jar</ejb-client-jar>
