Subject: Problem with manifest and executable jar


I need a second set of eyes to view my manifest generated by Ant.  I'm
trying
to build a simple executable jar with only 1 class and a couple of support
libs.  Should be simple but I can't get it to run.  When I attempt to I get:

Could not find the main class. Program will exit!

Here's the manifest generated by ant:
-------------------
Manifest-Version: 1.0
Created-By: Apache Ant 1.5.1
Main-Class: com.bpcs.web.RouterIpSync
Class-Path: ftp.jar jakarta-oro-2.0.6.jar
Built-By: wpfeiffe

Name: com/bpcs/web/RouterIpSync.class
Specification-Title: UpdateWebHome
Specification-Version: 1.0
Specification-Vendor: BPCS
Implementation-Title: UpdateWebHome
Implementation-Version: 1.0
Implementation-Vendor: BPCS


Table of contents for my jar:
----------------------------
META-INF/
META-INF/MANIFEST.MF
com/
com/bpcs/
com/bpcs/web/
com/bpcs/web/RouterIpSync.class
ftp.jar
jakarta-oro-2.0.6.jar

Note that I have coded and tested the RouterIpSync class with a main method
and it works just fine.

Any ideas??

TIA,

Martin,

Using the java -jar <mymain> showed me that my class was indeed found but
the supporting classes in the support jars were not found.  I did some
research and found that I cannot use the Class-Path to refer to jars within
my jar but should expect them to be present in the same directory as my jar.
I removed the support jars from the jar I am creating and just put them all
in one directory.  I then reran the jar and it worked.

Thanks for the heads up and putting me on the right path.
