I've had success in pointing Eclipse to the source code that I have

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.
The tool that generates the java code for the parser from
sqlgrammar.jj is Javacc. The generated code is in
generated/java/org/apache/derby/impl/sql/compile which is fun to look at
but shouldn't be changed.
I think there may be an exclipse plugin for javacc but I have never used
one.
