Hi Christophe,
Thanks for contributing this useful enhancement. I have updated
jde-util.el to include your contribution, making a few changes to
simplify the code. Your contribution will require a similar
enhancement to be made to the command for finding the definition of
the symbol at point so that it supports symbols defined in source code
stored in jar and zip files. I plan to make this enhancement as soon
as possible. Users who want to get your enhancement can do so by
downloading the latest version of jde-util.el from the JDEE CVS
repository.
