Unable to deploy webdynpro application

Hi,

I'm unable to deploy my webdynpro application from NWDS SP14. Following is the error message getting every time I try to deploy.

Caught exception during application deployment from SAP J2EE Engine's

deploy service:java.rmi.RemoteException: Error occurred while updating

ear file ./temp/deploy/work/deploying/mdp_abc_wd.ear. Reason: Already

started operation with application mdp_abcwd in the

cluster. No other operation with this application is allowed at the

moment. (message ID:

com.sap.sdm.serverext.servertype.inqmy.extern.EngineApplOnlineDeployerImpl.performAction(DeploymentActionTypes).REMEXC)

Deployment exception : The deployment of at least one item aborted

I tried undeploying from SDM but it fails. I even tried removing the application from Deploy section of Visual admin but I couldn't.

Is there any way where I can deploy my application?

Thanks for your time.

Best Regards,

Shiva Kumar
