Hi All,

So basically title says it all but I have two java programs on same machine, trying to get them to talk through spring's httpinvoker service. I have done this before with no problems so I am little confused as to what could be happening here as the error seems to have to do with serialization/deserialization but that should all be handled by java's library classes. Any ideas on where I should look for the problem?

Below is the stack trace:
