Cannot deploy "Hello World" application using SAP NW CE 7.1

[Former Member]

Hello,

I am having problems deploying a simple application to NW CE 7.1 (Welcome application

from NWDS tutorial).

I try to deploy from the NWDS. When I am executing "Deploy new archive

and run" I am asked for user and password.

According to the documentation I give following credentials:

SAP NetWeaver Application Server (e.g. for deploying applications)

username: Administrator

password: <your master password>

However after typing that I get immediate error in NWDS.

ConnectionException,cause=[ERROR CODE DPL.DCAPI.1144] NamingException.Cannot get initial context.Reason: Exception during getInitialContext operation. Cannot establish connection to the remote server.

Then the browser opens with following URL: http://localhost:50100/webdynpro/dispatcher/local/Welcome/WelcomeAPP?SAPtestId=38 and the following stack trace is shown.

"Application error occurred during the request procession."

Details: com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object 'local/Welcome' is not deployed on the server. Please check the used URL for typos.

Hi,

R u sure that you have created your welcome application in the same system where the server is present if not then check the J2EE engine Status. Go the Windows Tab and Click preferences and Click On SAP J2EE Engine Tab there and type the IP Of the server And 3901 as the port.

And check

Hi Pawel,

Are you sure you gave the correct user name & password for the server during the deployment (this should be same as what you gave you during the server installation).

Moreover, two applications with same complete name (including namespaces) cannot be deployed on the server. It might be that one application with the same name may be already deployed on the server due to which the NamingException comes.

You can try checking the application URL without the last id parameter (remove everything after WelcomeApp)

If this does not work, you try creating the project with a diff name & also diff application name.

Then build the project, deploy it (provide proper user details). If no error comes, then you can run your application.

Kind Regards,

Nitin

Hi!

For some reason, I am not able to deploy my application again (although it worked for a couple of weeks now)....
