Cant start a deployed application in weblogic 10.0

[lakshmi desai]

I have a web application thats deployed in weblogic 10.0, but I cant start the application from weblogic console. I can see that the application is installed, when I go to "Deployments" on the console. However when I try to start the application, it wouldn't. The error says "weblogic.management.ManagementException: [Deployer:149001]No application named '_appsdir_QW_war' exists for operation start" .

Here's the overview of the installed application:

Name: _appsdir_QW_war
The name of this Enterprise Application.More Info...
Path: C:\ bea\ user_projects\ domains\ ia71944\ autodeploy\ QW. war
The path to the source of the deployable unit on the Administration Server.More Info...
Staging Mode: stage
The mode that specifies whether a deployment's files are copied from a source on the Administration Server to the Managed Server's staging area during application preparation.More Info...

Can anybody help me fixing this.

Thanks much..

I have had similar trouble with auto deploy before. Try deploying from a specific location instead. Clear out your stage directory after deleting the war file, since it may contain application libraries that were bundled with the war.
