Including jars into executable jar

Question

Hello
I want to create an application in one application even if this application depends by many other jar libraries.
So , my development process resulted into one library: myapp.jar
This application depends by other jars: lib1.jar, lib2.jar, lib3.jar,
If I'll create one big jar archive with my classes and these libraries doesn't work (even I'll specify in manifest file all tags:
Class-Path: lib1.jar lib2.jar lib3.jar
Main-Class: com.snt.xdoc.MyApp
So, it is possible to create one single JAR archive including all resources (my interesting point is to include jar libraries) and executable class to know where are these resoures (to establish corectly the classpath)?
Thank you

Hello Stefan

But you might want to take a look at META JAR UTILITIES : http://www.yagga.net/java/metajar/
"Three classes with full source code and documentation that allows to extract resources from a file, from inside a JAR file that is currently executing (java -jar foo.jar), from a JAR that is included in the aforementioned executing JAR and to define a classLoader that can work with JARs, even if those JARs are JARred inside the currently executing JAR."
MetaJarUtilities are being distributed with full source code under GNU's General Public License.
For the moment being a JAR structured like this works:
FOO.jar
+- SuperMetaJarTest.class (uses BootstrapJarClassLoader.class)
+- net/
| +- yagga/
| +- util/
| +- BootstrapJarClassLoader.class
|
+- metatest.jar (content below)
| +- net/
| | +- yagga/
| | +- util/
| | +- Meta Jar Utilities classes here...
| +- jars/
| | +- test.jar
| +- TestmetaJar.class
| +- text.txt
|
+- jars2/
+- test2.jar
Good luck!
