I've had success in pointing Eclipse to the source code that I have built. I
have had a nice look around for the file that I am
interested in, which from the previously mentioned JIRA issues etc suggest a
file called sqlgrammar.jj
only problem is I can't find it!
It's possible that Eclipse doesn't grok '.jj' files in its normal configuration.
The file should be in your source tree as:
./java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj
There is a compiler-generation tool that processes this file during
the Ant build of Derby and generates Java source from the grammar.
thanks,
