Troubleshooting

If you experience problems with the Jackrabbit JCR server, please check the following:

Did you encounter an exception? Copy the exception stack trace somewhere so you don't loose it. The stack trace contains valuable information for the Jackrabbit developers if you need to file a bug report for the problem you encountered.
Is the repository up and running? Try browsing the default workspace to check if you can still see any content in the repository. You will see an error message if the repository is not available.
What were you trying to do? Try to verify that your client code or other manner of repository use is correct. Did it work before or are you trying to do something new?
Are there any notable log entries? Check the log files for any related warnings or errors. By default the Jackrabbit JCR Server writes log entries to the standard output of the servlet container. You can customize logging by editing the /WEB-INF/log4j.xml file and redeploying this web application.

If none of the above steps help you identify or resolve the problem, you can contact the Jackrabbit users mailing list or report the problem in the Jackrabbit issue tracker to get support from the Jackrabbit community. When contacting the community, please include any relevant details related to the above questions and the environment information shown at the end of this page.
