If you are migrating your configuration from an earlier release of WebSphere® Application Server, you should be aware of the various features that have been stabilized in this release.
Category | Stabilized Function | Strategic Alternative |
---|---|---|
Proxy components | Use of the on-demand router (ODR) for HTTP and Session Initiation Protocol (SIP) | The features of the ODR for HTTP are being
implemented in the WebSphere Web server plug-in for Apache and IBM
HTTP Server (IHS). All new intelligent management features will be
implemented in the Web server plug-in rather than in the ODR. The strategic alternative to the ODR for SIP is the SIP proxy server. Read Intelligent Management for web servers overview for more information. |
Use of the WebSphere Proxy for HTTP only The WebSphere Proxy is not being stabilized for SIP. |
The features of the WebSphere Proxy are
being implemented in the WebSphere Web server plug-in for Apache and
IBM HTTP Server (IHS). All new features will be implemented in the
Web server plug-in rather than in the WebSphere Proxy. Read Intelligent Management for web servers overview for more information. |

System administration | Intelligent Management support for the following
assisted lifecycle middleware server types:
|
Use wsadmin scripting to manage these middleware server resources. |

Application programming model and container support | Use of the Common Base Event application-programming
interface (API) for problem determination |
None |

Application programming model and container support | ActiveX to Enterprise JavaBeans (EJB) Bridge | Do not use Active X to access EJB. |
WebSphere Application Servers V4 Data sources and ConnectionManager | Use the WebSphere Application Servers Data sources (non-V4) and ConnectionManager. | |
Use of CommonBaseEventLogRecord for logging | Use standard java.util.logging API for logging; and when needed, use High Performance Extensible Logging (HPEL) log and trace facility's LogViewer command to convert log and trace messages into Common Base Event XML. | |
System administration | WebSphere Application Server Reliability, Availability, and Serviceability (RAS) basic logging formats—System.out, System.err, trace.log, and activity.log | Use the High Performance Extensible Logging (HPEL) log and trace facility to improve logging performance as well as to improve analysis and merging of logs. |

---|---|---|
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: |
