Hi.
Im trying to upgrade the weblogic version from 10 to 12 for my application.
Im getting below mentioned error while deploying ear file in weblogic 12 which works fine with version10.
" java.lang.IllegalArgumentException:[HTTP:101164] User defined class com.ab.util.session object is not a listener as it doesnt implement the correct interface."
Deployment is getting failed because of this error.
If i comment out listener, deployment is success.
