Migrate EJB applications
Find information about migrating enterprise beans.
Based on the EJB specification, enterprise beans are Java components that typically implement the business logic of Java EE applications as well as access data.
- Migrate enterprise bean code from Version 1.1 to Version 2.1
EJB Version 2.1-compliant beans can be assembled only in an EJB 2.1-compliant module, although an EJB 2.1-compliant module can contain a mixture of Version 1.x and Version 2.1 beans.
- Migrate enterprise bean code to the supported specification
This product supports the EJB 3.1 specification.
- Adjusting exception handling for EJB wrapped applications migrating from Version 5 to v8.5
Because of a change in the Java APIs for XML based Remote Procedure Call (JAX-RPC) specification, EJB applications that could be wrapped in WebSphere Application Server Version 5.1 cannot be wrapped in v8.5 unless you modify the code to the exception handling of the base EJB application.
