Hi all ,

I am trying to cluster an application in jboss 4.2.2GA , for which I am getting a NotSerializable exception as follows:

I am unable to understand why am I getting this exception stack trace.
Please respond me if any one have any idea about this.


Thank you

java.io.NotSerializableException: nextapp.echo2.webrender.Connection


You probably have this object in the session and when the session is being serialized, its throwing this exception because this object is not serializable (does not implement java.io.Serializable).

Hi,

Basically, I am using the Echo2 jars in my applications, of which the Connection class belongs to those. I have modified that Connection class making it to implement Serializable interface. Now, I got a new stacktrace pointing to RequestFacade.java




And I also found that "org.apache.catalina.connector.RequestFacade" is found at "/jboss-4.2.2.GA-src/thirdparty/jboss/web/lib/jbossweb-src/org/apache/catalina/connector" package. But I am not finding way how to avoid this exception.


Please let me know if any of you have ever tried with clustering jboss!! I hope many of you actively participate in this discussion.


Thank you!!
Sri.
