Problem in Deploy: Module Locked

When I try to deploy a certain project that had been recently undeployed, the following error message is displayed:

Deploying application in domain failed; Cannot deploy. Module directory is locked and cannot be deleted: C:\Sun\SDK\domains\domain1\applications\j2ee-modules\MyWeb Cannot deploy. Module directory is locked and cannot be deleted: C:\Sun\SDK\domains\domain1\applications\j2ee-modules\MyWeb

I tried the following steps:

1. Clean Project

2. Build and Clean Project

3. Export war (overwrite the existing war file)

but the error still occurs.

I also tried restarting the application server but the error is still there.
