I have created an executable JAR with the manifest:
Manifest-Version: 1.0
Main-Class: MyClass
Class-Path: lib/ext.jar
I can successfully run this JAR if I have folder lib with dependent ext.jar in the folder of .jar created.
I would like to embed ext.jar in my executable JAR to launch it anywhere I want, without creating lib folder. This would allow the JAR file to be self-contained, including all of its dependencies.
Is there any way to do this?
The default Java class loader cannot find an embedded jar inside a jar file. You will need to set your Java program to use a class loader which can deal with embedded jar files. As fas as I know, I have not seen one in any opensource libraries so you may need to write one yourself.
Alternatively, you can extract all the jar files and combine the the content into a single jar file.
Clean way to combine multiple jars? Preferably using Ant
