Repacking a file inside a java archive with nested .jars

Hello,

I need to repack a file inside several java archives (nested .jar files) with or without overwrite.

I am using a manual approach with mc, but it's painfully slow progress.

For example I want to refresh a file deep inside a java archive (with nested .jar files):

I have a java archive structured like this:

/home/jboss/
file1.ear which contains a 2nd archive file2.jar and inside a 3rd archive + subdirs file3.jar/Report/Web

I want to copy
and repack
Code:
myfile.class

inside that file
Code:
/home/jboss/file1.ear\file2.jar\file3.jar/Report/Web



I want to know if it's possible to write a shell script/command in RHEL 5 to resolve this problem efficiently ?

Many thanks.

I was able to repack (with $JAVA_HOME/bin/jar) a file into my archive, but only in root.

Code:
[jboss@srv ~]$ jar uvfM /home/jboss/file1.ear myfile.class
adding: file.class(in = 2405) (out= 1291)(deflated 46%)
