Re: How to package part of Java tool as binary? (Was: Debian/Java)
There are more than one ways to do this. My suggestion is to have two
packages:
cdk-java (command line)
cdk-gui-java (swing stuff)
the command line package needs to be compilable with a free javac (gij,
jikes etc). As for the binary I don't think it provides any real benefit
besides a slightly reduced startup time (and even that is not always the
case). Just make a wrapper script that calls java with the appropriate
options/classpath. Making a binary would cause problems if the gui stuff
uses classes from the command-line package.
Roughly you will end up with:
cdk-java Depends: java-virtual-machine
cdk-gui-java Depends: cdk-java, java2-swing (or whatever).
