Compatibility of RMI Calls / EJB Calls from Weblogic 14.1.1.0.0 to Weblogic 10.3.6.0

Question

I am facing issue when I am trying to call the Remote interface that is deployed on another server.

Initially I was getting [Security:090398]Invalid Subject: principals=[ error. On searching I found out that I need to enable global trust between these 2 Weblogic servers.

I used this reference article from Oracle website to enable Global trust

After enabling global trust, now I am facing below error.

Update :-

There were multiple jars with the same class that's why I was getting below issue. But somehow Now I am again facing [Security:090398]Invalid Subject: principals=[ error. Not able to understand what is happening. Could some one please hep me out with this ?

Not able to understand which configurations are exactly missing ? Could anyone please help me with this ?

Thanks in Advance.

Answer 1

java.lang.NoClassDefFoundError is pretty similar to ClassNotFoundException. Make sure the CLASSPATH of the problematic WLS instance, includes the jar file including the com/org/DataType class.
