Problem during Web Dynpro Deployment

Hi,

sometimes (I donu00B4t know why and when) the deployment of my Web Dynpro project hangs up.

The deployment output view in Dev.Studio says that

- asynchronous deployment started and

- a temp. copy has been created successfully.

But then nothing goes on.

Connecting to SDM remote gui is not possible because an administrator ist already connected via API.

Looking at Visual Administrator shows a red STOP in front of my Application (under services/deploy/).

Trying to remove the application is not possible. Nothing happens after pressing the button.

Trying to start the application hangs up the Visual Admin.

And here is the output of SDM log:

Jun 11, 2004 11:07:03... Info: ***** Begin of SAP J2EE Engine Deployment (J2EE Application) *****

The only way to solve this problem at the moment is to restart the server. Is there any other way?

Thanks in advance

Helmut

    Hi Helmut,

    please check, if there isn't a possible endless loop somewhere inside one of the controller implementations. I encountered this strange behaviour sometime ago in conjunction with a programmatic error in a supplyFunction, using the Context-node methods moveFirst() and moveNext(). I used a while-loop checking if the current node element is null, but without doing the moveNext() call, so the element never got null.

    The result was, that the WD server application couldn't be activated after deploying, was errorneous stopped (like in your case, displaying the stop-sign in the deploy-view of visual admin) and the application lock for the deployment was never released. You can undeploy such a server application after server restart only. Very nasty.

    Hope that helps.

    Best regards

    Stefan

      Hello Helmut,

      the same error ("cannot determine sdm host (is empty)") occured several times on my system. It had nothing to do with Web Dynpro specifically, as I developed another type of component. BTW: After deploying several times, I had to restart the Dev. Studio and then everthing went OK (until some deployments later when the same error came up again).

      So, I assume having a system malfunction and not an OSI 8 layer problem 😊

      Regards
