Re: my jar file will not run. main class not found

hi
My jar file I made will not run. I get the dreaded and vuage Main
Class not Found error. If I unpack the jar file in the directory and
run it with the java comand without the -jar then it will run. but I
can hardly distribute it like that.

I looked at the manifest.mf and it seams to be fine. the class is
where the mainifest says the main-class is.

I am calling it with this commandc

"java -jar src\ARBBatch_production_128_20091109.jar"

and here is the manifest

Manifest-Version: 1.0
Class-Path: lib/mail.jar lib/wordutil.jar lib/activation.jar lib/
commons-lang-2.1.jar lib/SQLUtil.jar
Main-Class: gov.doc.client.main.ClientBatch

the ant build script adds some other details but leaves it with it's
line return.

if you look in the archive the class is infact under <archiveRoot>/gov/
doc/client/main/ClientBatch.class
