Ok. Here we go: download the latest win32 version or get the generic zip installer. Both container WebLogic Server 10.3.5 and the Oracle Enterprise Pack for Eclipse (188.8.131.52.2). Together with the latest Java(TM) SE Runtime Environment (build 1.6.0_24-b07) and the Oracle JRockit(R) (build R28.1.3-11-141760-1.6.0_24-20110301-1429-windows-ia32,compiled mode). The documentation is also available online. Find the WebLogic documentation in a separate book. In general there is not much to see. The "what's new section" is nearly empty and I honestly don't see any breathtaking news. There is even still an old Coherence 3.6 version bundled with the download. Odd.
Looking at the WL_HOME/wlserver_10.3/bugsfixed/bugsfixed.htm you can see, that they fixed four (4) bugs ;)
EJB: A NullPointerException sometimes occurs when an EJB client performs a JNDI lookup for an EJB application that is deployed on a cluster.
Web services: Unable to attach a custom WS-policy to a JAX-RPC Web service.
JMS: A JMS Messaging Bridge fails to connect to a secure destination.
Core components: libstackdump.so is missing from the software distribution.
Nice. This could be considered as the last stable release here. Now we are all waiting for the first Java EE 6 version to come out.
