I will gently suggest that this is your first and root problem. Embedding the frameworks (all of them!) in the Application can avoid so very many headaches.

For a small site you don't strictly need Apache. But when you get larger and want to run multiple instances of your application to scale up, then you want Apache (or something that helps to distribute the load, Apache is probably the easy, cheap option here). > I know requests are getting through to the Linux server (checked with > tcpdump), and I can see the request in the WO application log with the > following error, which I can't see to find anywhere on the net. > >> [2012-3-13 2:40:43 GMT+00:00] <WorkerThread14> java.lang.InstantiationError: >> <jaboo.proto.websvc.Application>: Unable to create ERXWOContext54 I think that means (and yeah, it is freaking obscure) that the version of Wonder that is on your dev machine is much older than what is on the server.
