Hello, I am calling a EJB session bean running on a WebLogic server from an EJB session bean running on a Websphere 6.1 server.I am testing this through my JUnit (and Universal Test Case)  on RAD7.I am getting this error which I am not sure how I should proceed on ...

Thanks for your time ...

What version of java are you running?

Is the sever running Weblogic under the same version?

The only thing I can really find about this error seems to suggest it is a problem with multiple differing versions of java being used

I will keep searching...

Hey Tim, I am using Java 1.4 on the Websphere on my side but I am not sure what Weblogic is using on their side.I have the Client Jars for the the EJB's do you think that the Client Jars might not be the correct ones that I have here?

Also ..digging in furthur there is a Serialization error too ....Thanks for your time

Then it probably means that the object which you are passing to the EJB is not declared as Serializable. Make sure it implements java.io.Serializable.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

But I am just passing a String and getting Back an Object from the WebLogic deployed EJB.Do I need to synchronize it even then ?

Also I dont have any say on the remore EJB classes

What Object is it? Is it a java.lang.Object (I doubt it) or is it some other class's instance?

>> I am using Java 1.4 on the Websphere on my side

And are you running the client under 1.4 as well?

The Clients that I have from the Weblogic side are compiled against 1.3 .Will this cause the problem?

Hello,  Are you sure the object you are sending between the two servers is exactly the same code in both?  You can use the java tool serialver that is located in the java/bin on both servers to see if they are the same.  Are you setting the class with a suid?  You really should be doing this to resolve this problem!!!
