Reading OS CLASSPATH from an Eclipse Plug-in ? [message #41186]

Hello,

I need to read the OS / system CLASSPATH from an Eclipse Plug-in, so as to
save needless user work to set the PATH for a Jar file that is already in
system CLASSPATH (db2java.zip, if you mind, but it could be anything in the
system CLASSPATH).

I have tried
String classPath = System.getProperty("java.class.path");

But it only returns Eclipse's internal classpath:

Class path =
E:\eclipse21M3\eclipse\plugins\org.eclipse.pde.ui_2.1.0\laun cher\slimlaunche
r.jar;E:\eclipse21M3\eclipse\plugins\org.eclipse.core.boot_2 .1.0\boot.jar

And I do not want to force my users to launch Eclipse using a modified
command line, such as with option -cp <...>.

How could I do that without resorting to JNI ?

Best regards,

Alex.

I am not sure if Eclipse has it, but Ant source code has classes to read OS
env vars.

yes, but it\'s quite a bit of work to do so :)
