Unable to connect to J2EE Engine using Visual Administrator

[sam_venkat]

I am running WAS 6.40 with J2EE Add-in. Until recently we were able to use the Visual Administrator tool but of late it is not working. We are getting the below error mesg:

"Cannot open connection on host: <IP addr> and port: <port>"

Also I am unable to access the J2EE Administration page thru the website http://<IP addr>:50000/

The J2EE trace and log do not show any errors. From SAP MMC the J2EE engine starts fine.

You can use the jcmon tool to view the J2EE processes...

If you can't access the website then the dispatcher process is NOT running...

Hi Sam,

If you have both ABAP and J2EE add-in in your WebAS 6.40, the MMC will only show the startup status of the ABAP stack. In your case, would that be your J2EE Engine not started or not able to start? You can check the developer trace from the following patch:

For J2EE Engine server and dispatcher:

\usr\sap\J2E\JC<inst no>\work

For J2EE Engine message server and enqueue server:

\usr\sap\J2E\SCS<inst no>\work

BTW, you can also manually try to restart the J2EE Engine by going to the trasaction SMICM in your ABAP stack and click on Administration -> J2EE Server.

Regards,

Marc
