Hi..
You can compare your Netweaver and J2EE server versions by the following:
J2EE server - WebDynpro console has about server link with Build ID
NWDS - Use About menu to see the version and build.
I would recommend installing the NWSD workstation from service marketplace. Its on the master J2EE DVDs.

pls could anybody help me on this issues.
vijai

It seems that some user is already logged into the system and using the services.
I don't how can you increase the number of session allowed in server.
But for now. You can just check who else is using server and ask them to stop.
You can restart the server and then try deployment. It will work then for you

Dear All,
I had installed SAP in my system.But when I am testing webdynpro application I am getting the belwo error. Please let me knwo what setting I need to do to avoid this error.
Error when processing your request
What has happened?
The URL http://hari:8000/sap/bc/webdynpro/sap/z_test_pg was not called due to an error.
Note
The following error text was processed in the system DEV : The URL does not contain full domain specification (hari statt hari.<domain>.<ext>).
The error occurred on the application server HARI_DEV_00 and in the work process 0 .
The termination type was: RABAX_STATE

Your SAP Internet Communication Framework Team

Hello,
Little extract from the SAP online help :
In Web Dynpro ABAP it is imperative that a client browser with a fully qualified domain name (FQDN) has access to the AS-ABAP. For this reason the full URL must be assigned to a Web Dynpro ABAP application when it is called. The URL must not be shortened (for instance, no domain specification).
More info on how you should do this can be found here :
[Click|http://help.sap.com/saphelp_nw70/helpdata/en/67/be9442572e1231e10000000a1550b0/content.htm]
This will solve your problem.
Success.

Yosemite update causes error 'run out of application memory'

Hi, i use a
Mid 2011, 13 inch MacBook Air with i7, 4gb ram and 66gb left on my storage (out of 256gb). Currently running OS X Yosemite 10.10, updated via Appstore 2 days ago.
Ever since the update, while carrying out usual task such as 'mail' and 'safari' concurrently, i get error message stating 'run out of application memory', the situation is even worse when i have to run excel and word at the same time.
Not sure if the new OS is taking up memory because my tasks are routine and i never had problem prior to the update.
Comments?
Cheers
David

Greetings Everyone,
I use a mid 2011 iMac 27", 3.4 GHz, 16GB 1333 Mhz DDR3 with 457.08 GB free and a 4Tb Thunderbolt drive as my backup and media player total contents 1.2TB.
Since I installed Yosemite and its update 10.10 my iMac takes for ever to boot up and everything has slowed to a snails pace and now I am getting this annoying "You Have Run Out of Application Memory" and you must force quit all of these application. Luckily I now have a back up for what I am working on and don't lose most of my work on projects having to force quit all of the applications that I happen to have open.
I have been using a Mac since it was a small rectangular box with a B&W CRT and I have never encountered a problem like this before with a new OS release.
This reminds me of the days when we used to go to lunch waiting for our mac's to render a project and hope it didn't crash and now its when I boot up a screaming hot machine and do my work on it.
Is there anything I can do or is this a "your stuck with it until an update fixes this or these bugs".
Comments?
Cheers,
Scott

Issues while running a WebDynpro Application through portal.

Hi,
I am trying to execute a webdynpro application through portal and facing some issues. I hope to get a significant help from the experts:
> Initially, a report is called from the portal which in turns calls the WebDynpro Application.
> After this, I am again trigerring "FIRE" event in order to go back to report.
At this step, portal shows a message "The Page Can Not be Displayed". Browser link field contains the event name which I am passing to the Fire Event.
Can anybody let me know the root cause for this issue? Below is the piece of code that I am using for navigating from Webdynpro to Report.
        l_sapgui_manager->fire(
          EXPORTING
            name = 'INDI'
        parameters = lt_parameters ).
lt_parameters contains some field values which are required in the report.
Thanks,
Ashish

Error while running the webdynpro application

HI All,
I am new to web Dynpro's . I was going through this link
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20d2def3-f0ec-2a10-6b80-877a71eccb68

After I deployed and run my application . I got the starting page which is a button and when I click the button it should open the pop up window.
But When I click the button , I am getting this error:-

Hi Neha,
Just see the following line of code :
IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("PopWin");
Here the string parameter "PopWin" is the name of the window that you have created at design time to display the popup window. Please check if the parameter that you are passing here is the same as your window name and it is also case-sensitive.

Tahzeeb.

Hi palani,
Check wether the JCO destination with name 'WD_ETOOLS_PTIP_RFC_METADATA' has been created or not if you have content administration access.
In content administration go to Webdynpro-->Maintain JCO destinations which will list all the JCO desiantions avaialbale in the J2EE server. select you destination name and click on test and check wether the connection is successful or not.
If the destination is not created ask your basis team to create the destination.
Hope this helps you..

Unable to Deploy and Run a WebDynPro Application in NWCE 7.1 DS

I have successfully built a test application in WebDynPro within the NWCE 7.1, but every time I try to deploy and run the application I get the following error:
No default system is configured in SAP System Registry [ERROR: Apr 24, 2008 10:32:51 AM /userOut/daView_category (eclipse.UserOutLocation) [Thread[Worker-19,5,main]] ]
It seems like a straightforward error, but when I go to the System Registry I cannot see how to set up a default system for the application. There is no "DefaultSystem" entry and so I am sure that I have to add one, but cannot find any documentation to help me do this.
Thanks.

First, thanks for the fast responses.
I had gone to SAP AS JAVA preference before, but couldn't figure out how to get my system to show up in the dropdown box. When you put in the server name and the 0 instance, it then finds the system and all instances under the system. That was my missing link.
I can now deploy and run and move on to my next (inevitable) problem.
Thanks again.

Problem in Running a Webdynpro Application Which uses itext.jar

Hi,
I have created a Webdynpro DC which uses a DC called xxx_lib which contains the external JAR Files. (itext.jar etc)
This JAR file is in my library path as well.
I have added the lib_dc as used DC under the webdynpro DC.
The Compilation and build went fine without any error. But when in run the Application Under ---> Content Administration --> Webdynpro , I am getting the following Error.
The initial exception that caused the request to fail, was:
java.lang.NoClassDefFoundError: com/lowagie/text/Element
Failed to create delegate .....
(Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
Please let me know if somebody knows the solution.
Thanks and Regards,
Sekar

Hi Sekar,
Please look into the link below.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/7b8180e5-0601-0010-0c94-9bccb92de9c1
Goto section 2.2.3.1 Defining Libraries Page No. 75
It gives you the entire process of creating the library DC and referencing the same in your WebDynpro project.
Hope this helps.
Regards,
Rekha Malavathu
