Could not load class
(weblogic.ant.taskdefs.perforce.P4Opened) for type

Hello,

I have the following problem: I created a WebService Client JAR file from a WSDL
file (WebLogic Server 10.0 on Windows XP), using clientgen. The BUILD was
SUCCESSFUL, but I found some missing Java classes when I used ant in debug mode
(ant -v -d):

How should I do to fix this problem ? 

Are two JAR files "weblogic_patch.jar" and "weblogic_sp.jar"
needed in wl.classpath ? 

Thank you in advance.
