I am getting an unusual error while running my application, just wondering if anyone has come across this before. I am using google protocol buffers, my servlet takes a request and tries to process it, I have the following code:

InputStream s = request.getInputStream();
AdRequest adRequest  = AdRequest.parseFrom(s);

After executing the second line I get the error below in Myeclipse debugger:

Source not found for ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 310

I am using Jboss app server. I get a HTTP Status-Code 500: Internal Server Error.

Does anyone have any suggestions/thoughts?

    I have sorted out the problem. The protobuffers.jar file was not being included in my projects .war file, even though I had added the jar to my project MyEclipse was not including it. Upon following the path to the Jboss server and looking inside the .war I found out the jar was not there. After copying it over to Jboss/…/default/server/deploy/myproject.war/WEB-INF/lib directory the error has gone away and I am able to send a request to the servlet.

    Thanks.

    Regards.
