Hi Knut Anders,
A new problem arises when I am using OpenGrok. In any source code view page, if
I click any variable name or function name, a "HTTP Status 500 -" page will
appear. By default, clicking a name should bring me to the main page of
OpenGrok and the results of searching the name string will be output. This
works fine before I use Java DB with OpenGrok.
The following is information shown in the error page:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from
fulfilling this request.

Hi Knut Anders,
Thanks very much. I deleted all files under the "data" directory. This solved
my problem. OpenGrok is running quite well now.

This probably happens because the database that was created with version
10.3.1 is still lying around. It needs to be upgraded to a newer format
too in order to support the required feature.
Since I suppose you have nothing stored in the database yet, the easiest
solution would be to delete the cachedb directory and rerun OpenGrok's
indexer to get a new database created with the new version.
Alternatively, if you want to preserve the contents of the database and
just upgrade its format, the following steps should do the trick:
1. Start the Java DB server
2. Run "java -jar /path/to/javadb/lib/derbyrun.jar ij" and execute the
following commands in the ij command-line interface:
connect 'jdbc:derby://localhost/cachedb;upgrade=true';
exit;
3. Run the indexer
