Use this page to set the default data source mapping for EJB modules that contain 2.x container-managed persistence (CMP) beans. Unless you configure individual data sources for your 2.x CMP beans, this default mapping applies to all beans within the module.

Applications | Enterprise Applications | application | 2.x entity bean data sources

Guidelines for using this console page:

• The page displays a table that depicts the EJB modules in your application that contain 2.x CMP beans.

• Each table row corresponds to a module. A row shows the JNDI name of the data source mapping target of the EJB module only if you bound them together during application assembly. For every data source that is displayed, you see the corresponding security configuration.

• To set your default data source mappings:

  1. Select a row. Be aware that if you check multiple rows on this page, the data source mapping target that you select in step 2 applies to all of those EJB modules.

  2. Click Browse to select a data source from the new page that is displayed, the Available Resources page. The Available Resources page shows all data sources that are available mapping targets for your EJB modules.

  3. Click Apply. The console displays the 2.x entity bean data sources page again. In the rows that you previously selected, you now see the JNDI name of the new resource mapping target.

  4. Before you click OK to save your new configuration, set the security parameters for the data source. Use the following steps.

• To define data source security:

  1. Select a row. Be aware that if you check multiple rows on this page, the security settings that you select later apply to all of those data sources.

  2. Select either Container or Application from the displayed list. Container-managed authorization indicates that WebSphere Application Server performs signon to the data source. Application-managed authorization indicates that the enterprise bean code performs signon. Click Apply.

  3. To modify the authorization method of a data source with container-managed authorization, you have three options: None, Default, or Custom login configuration. The reconfiguring process differs slightly for each option:

     • If you select None:

       1. Determine which data source configurations to designate with no authentication method.

       2. Select the appropriate table rows.

       3. Select None from the list of authentication method options that precede the table.

       4. Click Apply.

     • If you select Default:

       1. Determine which data source configurations to designate with the DefaultPrincipalMapping login configuration. You must apply this option to each data source individually if you want to designate different authentication data aliases. See the "J2EE Connector security" information center topic for more information on the default mapping configuration.

       2. Select the appropriate table rows.

       3. Select Use default method from the list of authentication method options that precede the table.

       4. Select an authentication data entry or alias from the list.

       5. Click Apply.

     • If you select Custom login configuration:

       1. Determine which data source configurations to designate with a custom JAAS login configuration.

       2. Select the appropriate table row.

       3. Select Use custom login configuration from the list of authentication method options that precede the table.

       4. Select an application login configuration from the list.

       5. Click Apply.

       6. To edit the properties of the custom login configuration, click Mapping Properties in the table cell.

• Repeat all of the previous steps as necessary.

• Click OK to save your work. You now return to the general configuration page for your enterprise application.
