Problem in Creating a jar file using java.util.jar and deploying in jboss 4

Question

Dear Techies,
I am facing this peculiar problem. I am creating a jar file programmatically using java.util.jar api. The jar file is created but Jboss AS is unable to deploy this jar file. I have also tested that my created jar file contains the same files. When I create a jar file from the command using jar -cvf command, Jboss is able to deploy. I am sending the code , please review it and let me know the problem. I badly require your help. I am unable to proceeed in this regard. Please help me.

Hi,
I have gone through your code and the problem is that when you create jar it takes a complete path address (which is called using getAbsolutePath ) (when you extract you see the path; C:\..\...\..\ )
You need to truncate this complete path and take only the path address where your files are stored and the problem must be solved.
