Re: Ongoing bsh interface problem

(I forgot to reply to the group earlier.)

Glenn,

The debian package is definitely broken. The java/lib directory in jde
2.3.5contains the following files:

LICENSE.apache      RIGHTS.antlr        checkstyle-all.jar  junit.jar

LICENSE.checkstyle  bsh.jar             jde.jar             sun_checks.xml

Not having the checkstyle-all.jar in your path shouldn't hurt unless you try
to run M-x jde-checkstyle.
