Error using wldeploy in unix environment

Question

I am trying to use wldeploy ant task to deploy and undeploy applications from my server in a unix environment, and keep getting errors there, and not locally on a XP development workstation. Below are my buildfile and the error that I am getting. Anyone have any ideas as to what may be wrong?
build.xml
<target name="undeploy" description="Undeploys app">
<wldeploy user="${user}" password="${password}"
adminurl="${adminurl}" remote="true"
     action="stop" name="${appname}" debug="true"
verbose="true"/>
</target>
And here is the error:
[wldeploy] weblogic.Deployer -debug -remote -verbose -noexit -name ${appname} -adminurl iiop://${host}:${port} -user ${user} -password ${password} -stop
[wldeploy] weblogic.Deployer invoked with options: -debug -remote -verbose -noexit -name broker-co

Hi Richard,
I had the same issue using Eclipse. I just tried to run the
ant script outside of Eclipse and it worked fine.
This is an Eclipse-Ant Class Loader issue.
In order to make it work in Eclipse, You have to :
1. Open the External Tool Run Configuration.
2. Select your Ant script.
3. Select JRE Tab.
4. In Runtime JRE section, choose Seperate JRE.
Hope this helps !
Eric
