Re: Build and Confiuration Managment with Ant... a.k.a. running Ant _ from_ JSP/Servlet

["Larry V. Streepy, Jr." <st...@healthlanguage.com>]

Ok, I'll ask the basic stupid questions:

1. Does this build file run properly when executed from the command
line?

2. Do you have optional.jar in your classpath (since it's using the
vssget task)?

3. If 1 is answered yes, are you sure that your command shell and
weblogic have the same classpath?

Nothing obvious jumps to my mind, so I'll just resort to easy questions
:-)
