Problems with Sap Netweaver Developer Studio- I cannot deploy

[Former Member]

Hi All,

I have a problem with Sap Netweaver Developer Studio i have installed JDK and NDS in my pc and i try to make the examples found in http://help.sap.com/saphelp_nw04/helpdata/en/d7/24503e0fbfc04ae10000000a114084/frameset.htm

I have finished to develop the applications(without problems) but i couldn't deploy them.

I have WebAS 6.40 SP 15

NWDS 2.0.3

EP 2004 6 SP15

I had many errors like "Cannot determine sdm host (is empty). Please configure your engine/sdm correctly ! " and others.

My questions are:

1. I read that maybe i have to install the NWDS 2.0.15 which has SP15 because it's a rule of thumb always to use the version that corresponds to the stack-level of your Web Application Server. Is this true?

2. In the tutorials what do they mean i have to start( launch) the SDM?

I did this: i started RemoteGui for SDM and did connect.

3. Have the tutorials any problems with the versions of my systems?

Because i had errors in the welcome project in some imports.

4. We will install EP 2004's and NWSD 7... will it solve all my problems.

Please i will appreciate if anybody help.

Thanks,

Ari

Guest,

you have to maintain the "SAP J2EE Engine" settings at Window / Preferneces menu.

and yes. you should always use the same version of the NWDS as the server is (in your case 2.0.15)

Thank you Achim,

I have maintained the SAP J2EE Engine settings at Window / Preferences menu,

as i read in the welcome tutorial and in other tutorials.

Our url portal is http://sapserver:50000/irj/portal the 50000 is the port number i need? Inside the server i found a port like 8101.

Do you think the installation of the proper version will solve my problem?

Did you run the examples included in the NWDS?

How can i start the SDM ?

Thank you for your help.

Regard,

Ari

guest,

- use the port and the hostname as you can see at http://<host>:<port>; under System Information

don't use any 50xxx port in the "SAP J2EE Engine" parameters (most likely the port would be like 36xx or 39xx)

- the other version won't solve that problem, but you should use it anyway

- yes, I've made some examples (does that answer help you

- you can restart the SDM server process within your NWDS in the "J2EE Engine"-view and the client with RemoteGui (but you don't need it to deploy)

Hi,

Go to Windows -> Preferences in Studio. Click on SAP J2EE engine. Specify the fully qualified domain name (or select radio button "SAP is installed on same machine") of your server. And specify 3601 as the message port. Alternately, you can find message port of your server by going to http://<server:port>>/ and SystemInformation on this page.

Also, its recommended you should have the same version of Studio as the WebAS.

You donot need to use RemoteGUI for deployment. All deployment happens from Studio except for Server patches etc.

That will solve all the problems. And you can deploy your applications.

Hope that solves,

Thanks,
