Web Dynpro need NWDI?

Hello Everyone!
Would like to know the following please...
Does NWDI need to be implemented when making changes to sap webdynpro java / abap?
If not, how do you export the sap webdynpro objects out of the portal and import into NWDS?
How do you make the modifications to webdynpro and export back to the portal?
Thanks!
Doris

Hi Doris,
Yes, you need NWDI for modification of SAP webdynpro Java. But for webdynpro ABAP you dont need NWDI.
For webdynpro modification:
- create domain, track in NWDI
- import necessary SCAs for modificaiton into track
-import development configuration within NWDS
- create project for the Development Component where you want to make modification
- Make necessary changes and checkin, activate and release.
- you will see your changes in portal.
Follow this link for more details for NWDI:

Nwdi-managed access of pcd-objects from java web dynpro

Hi,
im am trying to access portal pcd-objects from a java web dynpro component (namely getting and setting personalized iview properties). for locally managed web dynpro components this works fine with the code below.
when i try the same with a nwdi managed web dynpro component i run into problems regarding references to used dcs. for instance, i need to reference used dc SAP_JTECHS/tc/epbc/pcm/adminapi/java because the build needs tcepbcpcmadminapijava.jar which is inside the mentioned dc. but access permissions of this dc don't allow the dependency. when i try to "add used dc ..." in nwds i get the error message: illegal dependency: access list does not allow use of ...
has someone any solution for this problem? are there other ways of accessing pcd-objects from java web dynpro (nwdi managed!)?
thanks

     InitialContext iCtx = new InitialContext(env);
     return iCtx.lookup(pcdPath);

Hi Kust,
To access the PCD objects the code you used looks ok for me but your main issues is related to the dc access permissions. This thread discussed about the similar issue. Please review this below thread.

Web Dynpro callable object without NWDI

Hello Forum,
does anybody know if it is possible to create a web dynpro dc as a callable object without using nwdi? I have written a webdynpro app know I want to use it in a guided procedure where I can provide an input field for the dc and also get an output field from the dc.
Does somebody have a step by step solution?
Regards
Michael

Hi,
You need to have the SCs for local development of Web Dynpro callable object.
Refer the following documents for more details:

Hi,
First you need to import the WD application to your NWDS and then you need to checkout the code for making any changes after making the chanhes you have to checkin the code.
First you need to setup the portal path in
1. WIndow->Preferences->Java Development Infrastructure->development Configurations.
2. You have to create a client in DTR by going into DTR Perspective.
3. Import the configuration from the track (this is your standard WD application) in Development Configurations Perspective.
4. Create the project from Inactive DCs tab.
5. Navigate to WD Perspective and build the project.
6. Check out the code to make chnages
7. Checkin the code after making the changes
8. Test the application in Portal

Integrating Flex/Flash in Web Dynpro ABAP(Netweaver 7.0) need info!

Hi all,
I need to embed a flash or a flex object inside a web dynpro abap application.I am working in Netweaver 7.0 and i don't have enhancement pack 1 installed.Is it possible ? If it is possible can anyone please provide me the coding and configuration details.
Thanks,
Saikat

I'm afraid that the SAP supplied integration technology - call FlashIslands - is only available from NetWeaver 7.01 and forward. You could perhaps do some simple integration (very little data transfer) with the iFrame UI element - although the iFrame is deprecated in 7.0 and 7.01, but does return to full support in 7.02. The other option would be to use the NetWeaver Portal or NetWeaver Business Client and have two iViews within the page. One iView would have WDA and the other some external technology (BSP, JSP, etc) to host the Flash/Flex content. Not tight integration, but you could potentially use Portal Eventing to at least communicate events.

Help needed with Network UI (JNET) in WEB DYNPRO for JAVA

Hi all,
We are using Network UI element in our Web Dynpro Java. All is ok, but we have a problem with 'PRINT_PREVIEW' button. If you do click on this button, another window is open with a page preview, but always is shown the first XML loaded, in other words, if you load a XML and change it, print preview don´t show this changes.
There are some information about Network UI in SDN but nothing about our problem.
Can somebody help me?, we need show refresh data in print preview page.
Thanks for all in advance.
Gabriel Garcia.

Hi Ayyapparaj,
We are generating all XML (Type Repository, Data, etc...) and passing this new file to Network UI Datasource property.
Thanks for your response.

No NWDI activity asked while modifying the Web Dynpro java code

Hi,
We have 2 team in our project, one offshore team and one onsite team. We have NWDI also in our landscape.
I have created 1 project in my local NWDS from DTR using create project option from NWDI track , when i do any modification in that web dynpro code once it appears in my local NWDS, its asking for the activity, all this is fine.
But when my offshore team send me this project from offshore (offshore team also working on this project), i go to my local machine under C:\Documents and Settings\user\.dtc\0\DCs\xyz.org\.. (workspace, where all the project folders are created in my local machine ) and replaces the web dynpro project (which i created using create project option from NWDI track ) with the project which offshore teams gave me that is I copy paste the project folder I received from offshore team.
I closed the NWDS and reopened NWDS, i did repair and reload also, but now when i try to do any code modification in that project its not asking any activity at all. So i want to know the reason why its not asking activity at all while modifying the code.
if now i do any code changes, and since no activity is asked, it wont be transported to QA and Prd system.
Can anyone have any suggestion on this..

Hi GLM,
I think you might be right that some files are in read as well as write mode. I went to my local machine and checked the project folder C:\Documents and Settings\user\.dtc\0\DCs\xyz.org\testproject\_comp\.dcdef file , its not in read only mode, that is read only flag was not checked.
I again checked the mode of .dcdef file in other web dynpro projects which are asking for the activity in all those projects mode of .dcdef was read only that is read only flad was checked in .dcdef file. ( I am not sure is .dcdef file only giving this problem that si because of this file not in read only mode I am not asked for the activity)
So could you plzz tell me how to make in read only. when ever i click the read only check box of .dcdef file and reload the project in my NWDS. that read only check box is getting removed. how to do this..
regarding your query, landscape in offshore team and onsite team are different, client has not provided nay access to its landscape to ofshore team so offshore team can not check in / check out the code written by me and same applies to me I can not check in / check out the code written by offshore team , only option is offshore team do some changes in the code and send the project folder via email and I have to deploy in client landsacpe and do further modification.

Web Dynpro Application Deployment need server restart?

Hi Everyone,
When deploying Web Dynpro application on production environment, do we need to restart the sap portal system and server?
I have this issue that when ever we deployed new develop Web Dynpro application with new Abap Function module we need to restart our Enterprise portal production server. Is this really necessary. Is there other way to deploy Web Dynpro application with new Abap function module without restarting the server.
Please help,
Michael Mondelo

Hi michel,
for example , assume you imported a RFC bapi_flights from r/3 to webdynpro dc , and both rfc requests and webdynpro application is deployed to the development server and then moved to quality server.
now you have done some changes in the rfc bapi_flights i mean change in the structure .
case 1 : now with out reimporting the change to webdynpro application and you move the request to the quality r/3, your application dumps . because the structure change is not incorporated at your webdynpro DC.
case 2 : you have re imported the rfc incorporating the changes to the web dynpro applicaiton dc, now with out moving the structure changes request to the quality r/3 and you deploy the webdynpro Dc having the changes to your quality EP , still the applicaiton dumps because your appliction refers to the rfc with out structure change in quality r/3.
case 3 : you have moved the abap request having the strucutre change and also the webdynpro development component where the changes are also incorporated , now on moving both , your application might dump , because the meta data cache might have been not updated with the new structure change in the quality ep server. so you have invalidate the cache in the JCos you have used to import the rfc. or else on restarting the EP server , the new structure change will be updated in the server.
most of the cases Invalidation of cache works and in some cases you have restart the server fo the changes to update.

Web Dynpro application needs to never expire.

Hi
I have a Web Dynpro application (NW2004 SP12) that displays spreadsheet like sales data to anyone who walks past the screen in a common area in the office/s. It should therefore run unattended. It refreshes the data on a timer. The data comes from a back-end aRFC. Everything works fine but about every 1.5 days the application times out (session expires) and needs to be re-opened (this seems to be a large administrative problem to re-login at all the deployment sites).
It gives an error 500application has expired. Please restart with the refresh button
In testing/troubleshooting I used the direct URL to the application running on WAS and not through a Portal iView.
I also changed the System destination from using SSO to using a dedicated user to the back-end.
Does anyone have an idea on how to auto refresh a Web Dynpro application or auto-renew the session so that it can run forever or a way to re-login automatically?
Thanks in advance,
Rick Viljoen

Yes, this was my final solution. Here is the code for the htm page. It will refresh/reload every 6 hours. Hope it helps.
