including multiple jars in a single executable jar

[Allen Wallis]

Hi,
I am trying to package my application as a single jar file, say
app.jar, that can be executed using java -jar app.jar. The problem is
that app.jar requires extensions, say ext1.jar and ext2.jar. I know I
can use the Class-Path manifest entry to ensure that these extensions
are added to the classpath, however this means that I must send the
end-user 3 files - app.jar, ext1.jar and ext2.jar.

Can I package ext1.jar and ext2.jar inside app.jar so that I only need
the app.jar file in order to run the application? I do not want to
unpack the extension jars since they may be 3rd party jars and I would
prefer them to remain intact.

The goal of this exercise is to have a single 1-click executable jar,
the end user should be able to receive the file, and double-click to
run it.

Thanks
Allen

I can not see the problem in unpacking ext1.jar and ext2.jar and then
packing the contents into your app.jar even if they are 3rd party. Its an
easy and simple operation.
