packing java file into JAr file

[jacob deiter]

I have a java class file and its supporting jar files and want to pack it JAR,how It can be done.I read that ,packing jar inside a jar create problem

[Ernest Friedman-Hill]

Packing a jar into a jar doesn't cause a problem, per se; but the Java class loader won't know how to load classes from those "nested jars", so it won't accomplish anything useful, either.

[jacob deiter]

then please tell how it can be done??

Distribute your library JAR files next to your program JAR file:

folder
- prorgam.jar
- library1.jar
- lib/library2.jar

The manifest can then specify those JAR files in the Class-Path attribute:

Class-Path: library1.jar lib/library2.jar

Of course you should put all your library JAR files either in the same folder, or all in a subfolder like lib. That's just more consistent.
