I reinstalled NWDS, but it didn't help .

Alsoi i cann't get a connection to SDM.

By deploying, the process stops after creating of temporary archive.

Hi Oleg,

Welcome to SDN!

Please check if you configured J2EE Server in NWDS preferences.

Goto Window -> Preferences: "SAP J2EE Engine". Enter the values for Message Server Host and Messages Sever Port.

Cheers,

Hi Kranthi,

i configured NWDS correct and it worked some days ago.

I cann see the J2EE server in the J2EE engine view and stop or start SDM from NWDS.

Hi

Try to ping your server from your system

So that you will know whether you are able to connect to your server or not.

Start --> Run

Enter 'cmd'

in it enter the command 'ping <ip address of the J2EE server>

Best Wishes

Hi ,

The problem was solved by restarting of J2EE-Server.
