How to start weblogic instance using wlserv ant task

Question

Hi,
Iam using weblogic 8.1
Iam trying to write build script which starts remote weblogic instance and does deploy using wldeploy and restarts the instance.
First iam trying with starting weblogic.
==============================
<wlserver
               dir="${server.project.root.dir}"
               domainName="${weblogic.domain.name}"
               serverName="${weblogic.server.name}"
               host="10.106.90.50"
               port="8001"
               generateConfig="true"
               productionModeEnabled="false"
               weblogicHome="${weblogic.home}/weblogic81"
          username="weblogic"
               password="password"
               args = "-XX:MaxPermSize=512M -Xms256m -Xmx512m"
               action="start">
               <classpath refid="weblogic.classpath"/>
          </wlserver>
==============================
Iam getting an issue here , it starts the weblogic but automatically it stops the weblogic , without any exception.
as per their documentation
"When you use the wlserver task in an Ant script, the task does not return control until the specified server is available and listening for connections. If you start up a server instance using wlserver, the server process automatically terminates after the Ant VM terminates. If you only connect to a currently-running server using the wlserver task, the server process keeps running after Ant completes."
I understand what they are saying , but what is the remedy to it , how to rectify it. I tried starting default server it gives NPE.
ITs kinda very urgent for me any help , or available scripts will be very use ful.
Thanks in advance.

               <jvmarg value="-server"/>
               <jvmarg value="-Dweblogic.Name=MyAppServer"/>
               <jvmarg value="-Dweblogic.RootDirectory=${weblogic.config.dir}"/>
               <jvmarg value="-Xms256m"/>
               <jvmarg value="-Xmx512m"/>
               <jvmarg value="-XX:MaxPermSize=128m"/>
               <jvmarg value="-da"/>
