Re: [gentoo-java] CLASSPATH deprecated?

[Federico Fissore <federico@fsfe.org>]

There are mainly two ways to do this:

   1. use a "static" classpath in the form
      create symlinks to system installed jars and then run something like
      CLASSPATH="lib/commons-logging.jar:lib/commons-collections.jar"
      java MyApp
   2. ask java-config to do that for you
      CLASSPATH=$(java-config -dp commons-beanutils-1.6) java MyApp

My preference goes to the first way when packaging an application (if 
the application expects some jars in some folder) and to the second way 
when I run my own application (obvioulsy backed by a shell script: I 
hate writing the same stuff twice)
