why I'm getting NotSerializableException exception though I've implemented 'Serializable'

Question

I\'ve implemented Serializable in class \'userInfo\'. Still I\'m getting exception. Here\'s the output console -

java.io.WriteAbortedException: writing aborted;         


        

Answer 1

Pass -Dsun.io.serialization.extendedDebugInfo=true to the JVM for tracking the exact cause for NotSerializableException.

Eg: Add SET CATALINA_OPTS=%CATALINA_OPTS% -Dsun.io.serialization.extendedDebugInfo=true in the startup.bat
