Using Maven to deploy WebLogic applications

Question

Hi,
I am trying to get Maven (http://maven.apache.org) to do WebLogic deployments.
I am using WebLogic 8.1. Is there a Maven plugin available for WebLogic 8.1
deployment? I keep trying the following in maven.xml, but I keep getting the
exception below. I have wldeploy working properly from Ant 1.6.1 - I had to drop
weblogic.jar into ANT_HOME/lib, but it works.
Any thoughts on this most appreciated - if you have working plugin code that can
deploy, that's even better. Thanks!
yours,

Do you tried the maven j2ee plugin?
At least deployment it just copy a ear isn't it?
Deployment isnt a problem for me but I have trouble to start and stop the server.
