NWDS J2EE Engine Tab Not Showing Instance

[Former Member]

My client did a recent reboot of their J2EE Engine, and once they were done I was unable to deploy applications to the server. Each time I try I get an error stating:

"Deployment exception : Cannot determine sdm host (is empty). Please configure your engine/sdm correctly !"

My settings haven't changed and they say neither have theirs. The odd thing is that the J2EE Engine tab in NWDS no longer shows the instance (so I can't see the J2EE Server, the Dispatcher or the SDM nodes anymore) but I still see the Cluster Monitors as I did before.

I can still open the applications in my browser using the same url as before. Very strange. What could cause this? I doubt the message server is down as the application stil runs fine.

Any ideas on what I can have them check?

Any help would be greatly appreciated.

1.Enter the J2ee engine information and message port in the nwds:Go NWDS->

Window -> Prefrences -> SAP J2EE engine -> Here Enter the values of Message Server Host and Message Server Port.

And click on apply+OK

Chcek if the J2ee server is running or not?

Http:<host>:<port>/index.html ->click on system information(message port and host is present) and check the stus of server and SDM

Thank you. We had all our settings setup correctly as we had been using this setup for several months.

Not sure exactly what was the issue, but a restart of the portal instance seemed to fix the issue.
