Known Java ES 5 Compatibility Issues

There are two known compatibility issues between Application Server 9.1 and Java ES 5 (JES5).

1. The JES5 Service Registry is not compatible with Application Server 9.1 because of the JSF 1.2 version provided by Application Server 9.1. The Service Registry needs to be upgraded to JES5u1 prior the Application Server upgrade to 9.1. This limitation is also documented in the Service Registry documentation.

2. The JES5 Portal Server is not compatible with Application Server 9.1 because of the JSF 1.2 version provided by Application Server 9.1. Portal Server needs to be upgraded to JES5u1 prior the 9.1 upgrade to 9.1.

   On a Java ES 5 setup that has Portal Server on Application Server 8.2, upgrading Application Server 8.2 to 9.1 makes the Portal Server unusable. Application Server 9.1 uses JSF 1.2, but the JSF-Portlet bridge in Release 5 Portal Server does not support JSF 1.2. On Solaris/Linux the Portal Server needs to be upgraded to JavaES5 Update 1. On Windows do not upgrade Application Server to 9.1 if you want to continue using the Release 5 Portal Server, as Portal Server is not supported in Java ES 5 Update 1 on Windows.
