Questions on JDE are more properly directed at the JDE mailing list:

There is a helpful archive of this list at
http://www.mail-archive.com/jde@sunsite.auc.dk/maillist.html.
Your problem stems from the fact that the jdb that is shipped with the
latest 1.2 JDKs on linux is of a new architecture (based on JPDA). The
2.1.5 version of JDE does not work with this version of jdb.
There are several solutions:
1. Use 'oldjdb' instead of just 'jdb'.
2. Upgrade to the latest beta release of JDE, 2.1.6. There is a new
debugger in this version which is based on JPDA, and thus does not use
jdb. It is not yet complete, but is rather functional. Read the 2.1.6
release notes and check out the mailing list archives for information on
how to set this up - as it is still beta, there is no "formal"
documentation written up on it yet.
