Hi,

I would like to test the Web Dynpro in Java (already know in ABAP).

What do I need for this purpose ? Some Eclipse plugin or somethings else ?

Thanks for your answer !

Hi,

To develop a sample webdynpro application SAP NWDS is enough. You can work in Webdynpro perspective.

You should have access to the SAP Web AS to deploy and test your application.

Back !

Now, I have the information about my host and my instance number ! Thanks for your explanation !

However, there is the following error :

-

---

Exception while trying to deploy

Can't determine deploy mechanism.

Please check if there is a correct default system specified in SAP System Registry preference page and if this SAP System is currently up and running.

Does it mean taht I don't have the Java in SAP system ? Or anything else ?

How to know if Java is well installed in my SAP server ?

[Former Member]

Hi ,

Please check the system name.

Have a look at below link,

Hi,

you enter instance host and instance number.

Instance host is your server name.

Instance number is 00.

I think I should register my SAP instance identity

=> To check the server settings, choose the menu path Window u2192 Preferences u2192 SAP

J2EE Engine. (in SAP NWDS)

I have to find those information now

[Former Member]

Hi,

Yes you should resgister your SAP WebAS instance here..

After doing this go to window->Show view>Other>J2EE-->Select J2ee engine.Press Refresh button on the right side.

Is dispatcher, SDM and Server are in green color.

If yes, then no problem with those things.

If you deploy your webdynpro application..it will ask for deployment password,provide the deployement password of SDM and check.,..

Hope this helps you..

This password I got

But how to find the instance number for sure ?

[Former Member]

Hello,

Try accessing this page of your portal - http:/<host_name>:<port_number>/sap/monitoring/SystemInfo and check the value of the port given for message server.

Thanks,

Hi Smoltok ,

The instance should be 00 however if that is not working try with 02 OR 10.

You have to enter the Instance Host and Instance Number.

Instance Host: This will the name of your server.

Instance Number: The instance number which I have told you.

Withthese option just enter and do not press OK button, Instead press the "Register SAP Instance" Button.

Most probably these should work. Please revert back in case you need any further information.

Thanks and Regards

Pravesh.

Thanks all of you. Your answer are quite good and clear !

Just another point :

How to have access to the SAP Web AS and how to deploy ?

[Former Member]

Hi,

In your IDE go to Window>SAP J2EE Engine>Provide the message server host(ip) and message server port-->Apply and Ok

Check in J2EE engine wether all the nodes are shown green ...

Go to webdynpro project>right click on application name>Deploy New Archive and Run..

if you installed the server locally then you can give the host as local host otherwise give the ip of the machine where it is installed.

If you are using CE environment then provide the message server host and instance number..

Hope this helps you..

Hi,

> If you are using CE environment then provide the message server host and instance number..

The message provided is :

Exception while trying to deploy

Can't determine deploy mechanism.

Please check if there is a correct default system specified in SAP System Registry preference page and if this SAP System is currently up and running.

Well, I believe it can't find the JVM or something else needed....

Hi Smoltok,

The NWDS contains a plugin for webDynpro. You can just have a NWDS installed at your system and then you can start worrking on webdynpro JAVA applications.

Please note that you need a WAS with JAVA installations to run WDJ (WebDynpro JAVA) application.

Please go through these documents for help.

Hi

To run the application of Webdynpro Java we need NWDS IDE tool and to run the application we need JAVA Stack.
