If you are migrating from an earlier release of WebSphere® Application Server, you should be aware of the various features that have been stabilized in this release.
If a feature is listed here as stabilized, IBM® does not currently plan to deprecate or remove this capability in a subsequent release of the product; but future investment will be focused on the alternative function listed under "Strategic Alternative." You do not need to change any of your existing applications and scripts that use a stabilized function; but you should consider using the strategic alternative for new applications.
This article contains the following stabilization tables:
Category | Stabilized Function | Strategic Alternative |
---|---|---|
Application programming model and container support | Enterprise JavaBeans (EJB) entity beans: Container-Managed Persistence (CMP) 1.x and 2.x, and Bean-Managed Persistence (BMP) | Use the Java Persistence API (JPA) for new database and other persistence-related operations. |
Java API for XML-based RPC (JAX-RPC) The Java Community Process (JCP) is limiting the focus for enhancements to the JAX-RPC runtime for building Web services; therefore, WebSphere Application Server will follow suit and limit enhancements. |
Java API for XML Web Services (JAX-WS) will become the strategic runtime on which any new enhancements will be focused. The focus to ensure interoperability for the subset of capabilities that map to the JAX-RPC and JAX-WS intersection will be maintained; but all new enhancements related to updating to support new standards will be only in the JAX-WS runtime. | |
System administration | Application server administrative (wsadmin) scripting support for the Jacl language | Use Jython syntax for any new wsadmin scripting. |
J2EE resources | Support for configuring and using message-driven beans (MDBs) through JMS listener ports | Perform the following actions to use JMS
activation specifications instead of listener ports: |
