 An Ant wrapper task for the weblogic.deploy tool.  This is used to
 hot-deploy J2EE applications to a running WebLogic server.
 This is not the same as creating the application archive.
 This task assumes the archive (EAR, JAR, or WAR) file has been
 assembled and is supplied as the "source" attribute.
 
In the end, this task assembles the commandline parameters
 and runs the weblogic.deploy tool in a separate JVM.
