Hi, 

We use the IBM BPM v8.0.0, we implemented  BPD process application, which  has exposed inbound WS. We are having problems with calling this web services because we randomly get internal server error 500. There are no rules when will this error occur. Everything works, and  after restart of Process Server this  WS stops working, we recive error 500, until we restart process server agian. Some times we this call WS multiple times and before we recive this error. Did anyone had similar problems?

We check folder and class file mentioned in stack trace and they exist.

StackTrace errors:

Just curious to know if you've been able to resolve this issue?

Do you also see a "Bad Type" error or a "ClassCastException" error as well?

It's good you've noticed such a problem. But to run a website properly it will be even better if you let us know the result of your checking. That would help a lot to all the forum members, as, among experienced developers, there are a lot newbies who come here for help. Thanks in advance.
