Select from the drop-down list or click the ellipsis ( ) button to search for the type you need. Description: An optional description of the resource environment reference. Resource Reference page A resource reference identifies a resource factory reference of the enterprise bean. A set of resource references enables the application assembler or the bean deployer to locate all the references used by the bean. For each resource reference you want to add to your bean, right-click the Resource References node for the bean in the structure pane and choose Add. A Resource Reference page contains these fields: Name: The name of the resource reference used in the enterprise bean s code. Type: The Java type of the resource factory expected by the enterprise bean s code. (This is the Java type of the resource factory, not the Java type of the resource.) Authentication: An Application authentication indicates that the enterprise bean performs the resource sign-on programmatically. A Container authentication indicates that the container signs on to the resource based on the principal mapping information supplied by the deployer. Sharing Scope: Determines whether the resource can be shared. Your options are Shareable and Unshareable. This field is available for EJB 2.0 components only.

Editing entity bean descriptors An Environment Entry page has these fields: Name: The name of the environment entry. Type: The Java type of the environment entry. Value: The value for the environment entry. Description: An optional description for the environment entry. Keep these things in mind about environment entries: The bean provider must declare all the environment entries accessed from the bean s code. The value of the environment entry can be changed later at assembly or deployment time. The assembler can modify the values of any environment entries set by the bean provider. The deployer must ensure that the values of all environment entries are set to meaningful values. Resource Environment Reference page A resource environment reference maps a logical name used by the client application to the physical name of an object. Don t confuse resource environment references with resource references. A resource environment reference lets the client use a logical name to look up a resource bound into the server JNDI namespace. A resource reference permits the client to use a logical name to look up a local J2EE resource. For each EJB resource environment reference you want to add to your bean, right-click the EJB Resource Environment References node for the bean in the structure pane and choose Add. 126 Developing Applications with Enterprise JavaBeans

For each EJB reference you want to add to your bean, right-click the EJB References node for the bean in the structure pane and choose Add. An EJB Reference page contains these fields: Name: The name of the EJB reference. Link: The bean the reference is referencing. Type: The expected type of the referenced bean. Home Interface: The expected Java type of the referenced bean s home interface. For an EJB 2.0 component, this field refers to the remote home interface. Remote Interface: The expected Java type of the referenced bean s remote interface. Description: An optional description of the EJB reference. EJB Local Reference page Each EJB local reference describes the interface requirements that the referencing enterprise bean has for the local referenced bean. Use the EJB Local Reference page to define EJB local references only. To specify a reference to a remote bean, use the EJB Reference page instead. 124 Developing Applications with Enterprise JavaBeans

For now, examine just the Standard page for an entity bean. The page includes these fields; fill them in with the pertinent information: Name: The name of the entity bean. EJB Class: The fully-qualified name of the Java class that implements the bean s business methods. This information must be specified. Home interface: The name of the home interface of the bean. For an EJB 2.0 component, this field refers to the remote home interface. Remote interface: The name of the remote interface of the bean. Local home interface: The name of the local home interface of the bean. Local interface: The name of the local interface of the bean. Reentrant: Check this field if you want the bean to be capable of being shared by multiple users. Primary Key Class: The name of the class that makes up the primary key for the entity bean. Persistence Type: Determines whether the bean s persistence is managed by the container or by code you provided within the bean s code. Primary Key Field: This field is enabled only if you selected Container as the Persistence Type. The CMP field in the data source to which the bean maps that defines the primary key. CMP Version: This field is enabled only if you selected Container as the Persistence Type. The version of container-managed persistence used if the bean is a CMP bean. Abstract Schema Name: The schema name. This field is enabled only if you selected 2.x as the CMP Version. All of the Display information is optional.

Viewing errors in descriptors As you fill in the information for your deployment descriptors, look occasionally at the structure pane. If the deployment descriptor is missing required information or is otherwise invalid, an Errors folder appears at the top of the structure pane. Expand the folder to see the error messages. It s quite likely the width of the structure pane is too short to allow you to see the entire messages. Either expand the size of the structure pane, or simply point to the first part of the message and you ll see the message appear in a tooltip box: You can also choose to validate your deployment descriptors at build time.

Adding to and deleting from a deployment descriptor A new page appears in the content pane that corresponds to the type of node you selected. This sample image shows a security role being added to an EJB module. 3 Fill in the information requested on this page and a new node for that page appears under the node you selected in the structure pane. Double-clicking a top-level category node, such as Entity Beans in an EJB module, displays a page that contains all existing entries of that type. For example, if an EJB module contains two entity beans, double-clicking the Entity Beans node displays a table containing an entry for each entity bean. You can also use this page to add and delete entries or reorder them. To add an entry, click the Add button, then select the new entry in the table and click the Edit button. The appropriate page appears. Fill in the required information. Chapter 13: Editing EJB deployment descriptors 121
