Former Member · ‎08-17-2007

<b>hello all,</b>

I was going through a tutorial in SAP HELP about deploying J2EE application..

But couldnt get a clear idea WHY AND AT WHAT SITUATION WE WISH TO DEPLOY A J2EE APPLICATION.

<b>So can anyone give me some realtime situations where we use it.and after developing it in NWDS.How we import it in XI</b>

All your contributions are really valuable.

Thanks

Hi !!

By making special settings for the server process of the J2EE Engine and setting breakpoints, you can interrupt the execution of your Web application and go through it step by step.

Have look at this link

Check this document and try to troubleshoot:

J2EE web application has to integrate with SAP XI.

1. if the web app has to receive response from XI and render the same to the end user , then you probably must use EJBs which would be the client Java proxies in XI and your web app would be acting as a client to this EJB.

2. if based on the user interaction , the web app has just to trigger a background job then you have n number of options like

creating a file which XI will pick up
creating a JMS message and sending it to a Queue with which XI is connected using JMS adapter...

and so on...

3. You could also use the option of sending a HTTP or SOAP request directly to integration pipeline and then receive response.

all in all...everything will depend purely on the way your web app wants to communicate / integrate with XI.

Hi,

J2EE application can be either .ear or .sda or .sca. These files after developing in NWDS you have an option to deploy to J2EE engine from that tool itself.

You need to configure the corresponding system parameters in that tool. Windows->Preferences->SAP J2EE Engine, In this path u need to give the values.
