How do I configure an enterprise application using Weblogic 10 wlconfig

Question

Hi All,
I am converting an installer from WL8 to WL10. We use wlconfig to configure our EAR in wl8 with several wlconfig commands. These don't seem to work though when attempting to use wl10. The following error comes up more often than not and does not seem to be appropriate to what is actually happening.
Unable to create new bean of type WebAppComponent for pcidomain_new:Name=GenPortal,Type=Application:missing create method
I have searched the Weblogic Documentation and have found only general information on how to use wlconfig with a simple example that does not touch on application deployment. I have also found an MBean Reference but am unclear as to how to marry the two.
It would be really great if someone knew where I might find a concrete example of creating an Enterprise application using WL10.
Here is the current wlconfig task that we use successfully in weblogic 8.
${server-mbean} is read in earlier with a wlconfig query command.
          <wlconfig url="t3://${env.COMPUTERNAME}:${weblogic_port}" username="${weblogic_username}" password="${weblogic_password}">

               </create>

               </create>
               <set mbean="${domain_name}:Name=${domain_name},Type=JTA" attribute="TimeoutSeconds" value="1200" />
          </wlconfig>
As I mentioned earlier right now this fails with when trying to create the WebAppComponent as seen in the error message above.
Thanks for any help you can provide.

Here's a couple ideas:
1. Easier, but with non-deterministic response time:   Wire the button up to one of your I/O pins and poll it.  When you detect the button, issue a software call to stop the pulse train.  If the duration of the button press may be short compared to your polling rate, then wire it to a counter source pin and perform edge counting.  When you poll any value > 0, the press has happened.  (Sometimes the value may be >1 if the switch has "bounce").
2. Trickier, but with deterministic hardware timing:  Configure another counter, call it counter B, for triggered pulse generation.  Wire/configure the button as the trigger.  Make sure that the "high time" of the pulse is long enough to let your software respond, if needed.   Also configure your original continuous pulse train counter to use Ctr B's output as a "pause trigger", specifying to pause when high.   When the button is pressed, counter B will fire a pulse and that pulse will inhibit your original counter's pulse generation.  In short, the pulses will stop until counter B's pulse has completed its full duration.  Your software can monitor for this series of events and stop the original counter task if needed.
