Java SE (Java Platform, Standard Edition)

As far as I know, libraries package in Jar files can be copied to $JAVAHOME/jre/lib/ext directory and it can be directly used.

I don't have access to that directory. So I copied the jar file to D:\Shared\Java directory and then in the comand prompt type:

D:>set classpath=%classpath%;D:\Shared\Java

Compiling files that uses the jar package (it is the xmlrpc package actually) will produce error.

I tried extracting all the files in the jar package. That solved my compilation errors.

Is there a way to 'access' the files in the jar package without extracting it?
