Hi all, I figured a way to make the job of java packaging a bit easier. The current approach is to create wrapper scripts that define the classpath and call java with the name of class containing the main.
The problem is with package A depending on libraries from package B which in turns depends on libraries from package C. Package A needs to be aware of that and include both in the classpath. My solution is to have a custom classloader that is aware of /usr/share/java and with the possibilty of additional repositories. So as long as everything is under /usr/share/java all java packages can find all classes without the need for symlinks and explicit listing of jars in the CLASSPATH. So to create a wrapper for a java package you would only need to have a script that calls I have created the classloader (extends java.net.URLClassLoader) and it works ok. deb-java is the wrapper script for the classloader. It sets the classpath only for the jar file with the classloader and does: java -Djava.system.class.loader=DebianClassLoader $@ Examples: CLASSPATH is not set. ant can be invoked with: deb-java org.apache.tools.ant.Main argouml can be invoked with deb-java org.argouml.application.Main Package with the classloader and the sources are at: http://anarxia.dyndns.org:2180/debian/pool/ What do you think?
