Do you have an error message from your application? Then find the answer with Error Buddy. You can search over 40000 source code files and troubleshooting documents using our beta lucene/nutch search interface or if you prefer, search as normal using google. With LXR technology you can drill right down into the line of source code where it came from with full cross-referencing.
If after searching you didn't get your ideal answer, or you are still unclear what the error means, you can choose to post that question to the community forums following the link included in the search results.
