Are you using JDK 5? This is not supported for NW04s.

java.lang.UnsupportedClassVersionError: com/sap/xss/hr/per/us/personal/cc/wdp/InternalCcPerPersonal (Unsupported major.minor version 50.0)

at java.lang.ClassLoader.defineClass0(Native Method)

Portal,

You are using JDK 1.4 when executing code (i.e. your WebAS is running on JVM 1.4.x). But you are using JDK 1.5 when compiling code (i.e. your IDE is running on JVM 1.5 or JDK 1.5 is selected as compilation target) -- hence you get this error.

Recompile your code with JDK 1.4.x, re-deploy and try again.
