8.2.6 Configuration and code changes for migrated EJBs

EJBs developed in VisualAge for Java V3.5.3 follow the EJB 1.0 specification. these must be converted to EJB 1.1 specification level.

Since the process of converting involves exporting the EJB code from VisualAge for Java V3.5.3, importing the EJBs into VisualAge for Java V4.0, exporting from VisualAge for Java V4.0 and then importing into WebSphere Studio Application Developer V5.1.1, we recommend that you recreate the EJBs in WebSphere Studio Application Developer V5.1.1, unless you have a very large number of EJBs, justifying the cumbersome conversion process.

This section details the steps you must take to complete the migration of your custom EJBs. This includes the following configuration changes:

Change the access isolation level

Add the WCSecurity role

Change the container transaction type

As well as the following code changes:

Remove serialVersionUID constants

Ensure that ejbCreate returns primary key object

Remove java.rmi.RemoteException from remote methods

Match ejbPostCreate and ejbCreate methods

Remove FinderHelper interface

Regenerating the deploy code

It is assumed that you have already migrated your EJBs to WebSphere Studio Application Developer V5.1.1 using the process described in 7.5, “Migrating custom EJBs” on page 118.

Access bean string converters

In VisualAge for Java V3.5.3, you were able to specify string converters for the fields in the EJB when generating the access bean for the EJB, as shown in Figure 8-2 on page 145.

A similar step does not exist in the access bean editor in WebSphere Studio Application Developer V5.1.1. However, the access bean creation engine in WebSphere Studio Application Developer V5.1.1 does create the string converters for you, if you make sure that your EJBs are configured to use string converters.
