Unable to Connect to the J2EE Server from Netweaver Developer Studio

[Former Member]

I am unable to connect to the J2EE Server from the NWDS.

Settings I have made in J2EE Preference is

Message Server Host: <IP Address of the server> (have updated the hosts file)

Message Server Port: 3605

I can connect to the server from the Browser with the following URL

http://<IP Address of the server>:50500/index.html

But the J2EE View gives me the problem

"<b>Exception: The Message Server did not respond within 60 sec. Please check if the message server is running and the if the socket connection has been established."</b>

I tried Telnet <IP Address of the server> 3605

I get a blank console window. Am not sure if Telnet is working though....

The Server is installed on a Linux Platform and the NWDS on a windows 2000 machine.

Would appreciate any help possible.

Hi,

the message server port is wrong.

to check the message server port,

First go to main index page,as you said

<b>http://<IPaddress of the server>:50500</b>then click on the <b><b>Systeminformation</b></b> in the main index URL page.

enter the<b> admin user</b> details:

ex: user:<b>administrator

passwrd :password of administrator</b>.

then at the <b>top left corner of systeminformation page</b>,you get the details of <b>message server port.</b>

put that port number.it will work fine.

Hi

I know this is old thread but I just wanted to put it up here for other developers who might come across for the same problem..

This is so frustrating but I found it, use the frikkin port number 39xx, usually its 3901.. 36xx ports dont work.. never worked for me anyway..

Hi,

The message server port is wrong in your case. It needs to be specified as <b>36<SCS-instance-number></b>. In your case 05 is the JC-instance number, hence HTTP port 50500 is correct. Check the SCS-instance number.

HTH!

Hi Vladimir,

Thanks a lot for the reply.

How do I find out the SCS-insatnce number for the installation?

Thanks and Best Regards,

For example by navigating to /usr/sap/<SID>/SCS<b><number></b> on the file system of the server machine.

Hi,

let me clear the doubt.

When it is java instance, we have central services which has the message server.

So th port becomes 3600 + SCS instance number.

In case of ABAP instance it central instance has your message server. so the message port is 3600 + CS insatnce number.

In case of ABAP + java message port for java and the message port for ABAP are different as the above said statement.

Hope this clears your doubt.

Don't forget to reward points.

If you have any confusion ask me.
