Hi,

I'm trying to create a new custom Authentication from the Weblogic 8.1 console. I followed all the steps written in the Weblogic documentation to create my MBean jar file and I put it in the WL_HOME\server\lib\mbeantypes directory.

In the console, when I click on the "create" button to create my new provider, I get a NoClassDefFoundError, but no class is specified.

java.lang.ClassCastException: java.lang.NoClassDefFoundError
