title: Internal Server Error
body: <p>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:</p>
  
  <pre><code>InputStream s = request.getInputStream();
  AdRequest adRequest  = AdRequest.parseFrom(s);
  </code></pre>
  
  <p>After executing the second line I get the error below in Myeclipse debugger:</p>
  
  <p>Source not found for ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 310</p>
  
  <p>I am using Jboss app server. I get a HTTP Status-Code 500: Internal Server Error. </p>
  
  <p>Does anyone have any suggestions/thoughts?</p>
