3.3.1: Migrating to supported EJB specification
Migrating from Version 3.0x
The EJB specification level for Version 3.5 has not changed from that of Version 3.0x,
however changes due to the prerequisite of JDK 1.2 are required:
- In Version 3.02x, the JavaSoft standard packages:
javax.sql.*
javax.transaction.*
were present under non-standard names. In Version 3.5, they are present under
their standard names.
Any code using WebSphere Application Server data sources,
including BMP entity beans and session beans that access databases, will need
to be modified.
See articles 3.3.8 and 3.3.9 for instructions.
- Some of the stub classes for deployed enterprise beans have changed in JDK 1.2.
Repdeploy all EJB server JAR files to generate the
correct stub file references.
Be aware that, in general, JAR files generated prior to JDK 1.2 are source and binary
code compatible on a JDK 1.2 base. However, there are some incompatible cases. For
further details, see:
