IllegalArgumentException trying to run PetClinicClientServer

[dexter]

Hi,

I'm trying to get the petclinic server and client running. When I close the log in dialog (it doesn't matter if I log in or not), the following exception is thrown on the client end:

I take it that Hessian and Burlap are interchangeable, Hessian's serialization implementation producing binary data and Burlap's implementation producing XML documents. So, stabbing in the dark, I changed client-context.xml to use Burlap, but that caused the client to simply terminate after the log in dialog is closed.

I've deployed the petclinic-server web archive to a JBoss 4.2.2 instance, running on Mac OS X 10.5.

Any help is greatly appreciated!

Got it working with the latest version of Hessian/Burlap (currently 3.1.6). It was only today I noticed I was using version 2.1.12.

And if I enable serializability in the domain classes of Spring's sample app, communication works nicely over HttpInvoker, too.
