I have 3 jar files:
derby.jar
commons.io.2.6.jar
org.json.jar
I tried to combine them using jarsplice-04.0jar but the fat jar doesn't work. The only error message is the db is being accessed concurrently which just indicates the jar isn't working. I read the documentation for jarjar.jar but don't understand how to use it. Can someone provide some guidance or a step by step procedure for combining jars (including what you need to do with the manifest.mf files)?
This stackoverflow post How to combine two Jar files doesn't answer the question as it doesn't tell you how to combine the manifest.mf files which you apparently need to do.
