Weblogic.management.configuration.ConfigurationException: Unknown attribute

Question

Dear All,
I am using Weblogic 6.1 with Service Pack 2 it was working fine.
I tried to upgrade it by installing Service Pack 7, but it was giving some exception when I tried to deploy the ejbs on server.
Now I revert back to service pack 2 by uninstalling the service pack 7, but when I tried to start the server it is giving following error.
How to solve this problem? It's very urgent. Pls help me out.
The WebLogic Server did not start up properly.
Exception raised:
weblogic.management.configuration.ConfigurationException: Unknown attribute StagedTargets for MyWebApp, type Application

Answer 1

looking for StagedTargets into config.xml and delete this attribute.
StagedTargets means that one application was deployed over one (or more) server in mode stage.
I think that this attribute is not allow sp2 and is not very important.
