Basic question on a web dynpro application

Hi All,
I am new to NWDS 2004 and I just executed my first web dynpro application that is on https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/a-c/creating your first web dynpro application.pdf
I have couple of questions
1. when i click the back button the text that was entered in the Start view is visible even after I hit the back button in the result view. Can you tell me how to keep the input field empty in the start view after hitting back button?
2. After deploying the Web Dynpro application, where from the Portal, can i assign this web dynpro application to a user .
Thank you
Regards
Luke

Try putting adding this code to your onActionBack method.
public void <b>onActionBack</b>(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
//@@begin onActionBack(ServerEvent)
<b>String headerText = " ";
wdContext.currentContextElement().setHeaderText(headerText);</b>
wdThis.wdFirePlugToStartView();
//@@end

i have done all the steps,but when the explorer opens i get the following error
The requested URL could not be retrieved
While trying to retrieve the URL: http://saptd:8000/sap/bc/webdynpro/sap/zz_00_sflight?
The following error was encountered:

Hi
1.Go to Transaction RZ10
2. Select the Instance Profile and Check the radio button extended maintanence.
3. create a new parameter icm/host_name_full
   give the value as $(SAPLOCALHOST).domain.ext

Exchanging data between a Web Dynpro application and SAP Web Shop

I'll try to keep this as clear as possible:
1) We have the SAP Internet Sales system running, which has a series of Business Object classes and corresponding Backend Layer objects that can return data from several sources.
2) We are able to create our own Backend Layer objects that would return data from a component called IPC, which is a Java component.
3) I would like a Web Dynpro application to retrieve data from this backend layer object, but I am not experienced enough with Java to know if what I want to do is possible. I don't think that I can use JCo, because I am trying to get a Java component (class?) in Web Dynpro to access a Java class remotely.
4) I think I am asking is this: is there a way for a Java to Java connection to be created, much like Web Dynpro can use JCo to connect Java to ABAP systems?
If this is a glaringly obvious question to Java programmers, my apologies!
- Tony.

Somebody on another forum recommended using RMI. Which would be the better option in terms of ease of implementation?

How can I convert my Web Dynpro Application to Web Dynpro with GP Interface

Hi experts
I am trying to make my Web Dynrpo Application implement GP interface.
I encountered a question .
when I added GP interface controller, "Window" component also added automatically.
But I have already had a "Window" componet which contains alot of View settings.
Do I have to Use newly added GP "Window" component?
if so, do I have to recreate "Window" Componet whenever I convert to my web dynpro application implementing GP interface ?
Thanks in advance

Yes you have to use the automatically added window.
Check <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59">this</a> tutorial on how to implement a GP WD.

Error using tabs in Web Dynpro application

Hi all,
I am working on a web Dynpro application where I want to use "tabs" to display different vendor details, basically I need two tabs one for header data, one for address data. What I did is I created a group and there created the element for the user to enter the vendor number and also created a button and binded it with the BAPI, now I created a tab using tabstrip and then inserting the tab and adding the element to the tab (in my case i m using the table type), once I finish this and try to do the syntax chek i am getting this error: "ACC: Element "TAB" does not have a header"
Can you please help me with this?
Thanks,
Rajat

Looks like i was missing some step... I deleted everything and then re created and this time it works.

Calling a Web Dynpro Application from POWL feeder class

Hi,
I know this question is asked before but never answered, but I try again......
I have a own POWL feeder class where I defined a button in method IF_POWL_FEEDER~GET_ACTIONS.
I know that this action can be handled in method IF_POWL_FEEDER~HANDLE_ACTION.
When pressing the button I want do call another web dynpro application.
How can I do this? -> Any Example Coding?
Thank you and best regards, Edgar

Hi Vineet,
it works, thanks a lot!!!! Best Regards, Eddy
P.S.: Here is the coding for triggering the event and passing parameters for the selected POWL table line:
METHOD if_powl_feeder~handle_action.
DATA: ls_parameter TYPE powl_namevalue_sty.
DATA: lt_flights TYPE ty_flights.
DATA: ls_flight TYPE sflight.
DATA: ls_selected TYPE rstabix.
FIELD-SYMBOLS: <lt_fligts> TYPE STANDARD TABLE.
IF i_actionid = 'EDIT'.
*   Important: this triggers the event
    e_portal_actions-fire_wdevent = abap_true.
*   Pass parameters to event
    ASSIGN c_result_tab TO <lt_fligts>.
    lt_flights = <lt_fligts>.
*   Determine the first selected row
    READ TABLE c_selected INTO ls_selected INDEX 1.
*   Read selected POWL data
    READ TABLE lt_flights INDEX ls_selected-TABIX INTO ls_flight.
    CHECK sy-subrc = 0.
*   Pass parameters
    ls_parameter-key = 'ACTIONID'.
    ls_parameter-value = 'I_ACTIONID'.
    APPEND ls_parameter TO e_portal_actions-parameters.

GP, callable object Web Dynpro Application (bespoke) not appearing in list

Hey y'all
We're developing our first GP, and we would like to call an existing bespoke Web Dynpro. When creating the callable object, we're selecting type Web Dynpro Application, but our Web Dynpro screen is not appearing in the drop down list on the next page. We think that this is because the application has been deployed to a different server (i.e. it has not been deployed onto the portal server).
So the question is, has anyone faced this problem before, and is there a solution?
Kind regards
Jon

Hi John,
Please have a look at this Exception on creating GP Action
This will solve your issue definitively. Do not take care of a given SDA, just redeploy everything and make sure that everything is overwritten by selecting the right option.
Best regards,
David

Web dynpro application using workflow

Hi all,
I have developed a web dynpro application and attached that to the portal, so the user will login into the portal and will access the application. We have a new requirement now, when a user enters the data and hit save button on the web dynpro application, the workflow should trigger and should send the filled out (everything filled in) web dynpro application to his superior, the supervisor should be able to click on a link (which he should get through workflow) and should get the web dynpro application filled in. I am not sure how can I do this, so can you please guide me through.
Thanks,
Raj

Hi Raj,
could I suggest perhaps that you have a good search of SCN - there have been multiple posts about this sort of thing in the past.
for example : the wiki article
[Integrating WebDynpro ABAP applications with UWL for workflow in Portal|http://wiki.sdn.sap.com/wiki/display/WDABAP/IntegratingWebDynproABAPapplicationswithUWLforworkflowin+Portal]
is it perhaps that you do not use the UWL at your site? Or do you want to to send an email to the manager with a link directly to the approval application? The last case is one that I've come across many times before - it just means that you'll need to generate an approval task that is ended by a wf event and send an email to the manager with a URL parameter in the launch of the WDA application so that the app can pick up the details required to display and raise the WF event to complete the approval wf task.
There are all sorts of ways of persisting the information in the form so that the manager can see it in the approval. You can use the workflow container, you can use a db table, you could even use a shared memory area (not that I'd recommend this for this usage). But this is more a case of how to persist information in a workflow and probably a better question (search first, it's probably been answered already) for the WF forum and not the WDA forum.
Good luck in designing and building your application. Perhaps when you are done you could write a blog about your experience and further share how to do this with others.
Cheers,
Chris

Access Web Dynpro application on different WAS ??????????

Hi All,
Current Scenario -
We have deployed ESS & MSS Business package on one WAS and the iviews are present on another WAS.We have created a Dedicated R/3 system which is pointing to the WAS where these packages are deployed.
All these things are working fine i.e. once the user maps the id pswd it directly runs the Web Dynpro applications in the iviews.
That means, even if application is running on one WAS, and the user personalises data on another WAS, it still retrieves the credentials and shows the appropriate results for ESS MSS Packages.
Query-
Now i need to implement the same scenario in my Web Dynpro application
Steps
1) I have the WD application running on one WAS and portal on another
2) In portal there is a R/3 system created
3) The Web Dynpro application needs to know if the user has personalised mapping against that system created on portal(other WAS)
4) If yes show him the home page else take him to the login page.
Just as it is implemented for ESS MSS Packages.
How can i pass the mapped data to the Web Dynpro iview ?
Thanks and Regards,
Samta Nichani

Amol,
as this questions existed twice, I've deleted one.
As roles are in the UME, you can access them. But why do you want to do this? You could login to that user, but then the question is what you want to do....

Access users in a Web Dynpro application on different WAS ??????

Hi,
Scenario - I have a local WAS on which i have deployed a Web Dynpro Based application.
There is another WAS on which I have portal installed. I need to access the roles assigned to a particular user in my Web Dynpro application.
Query -
I need to know can i access the roles assigned to a user on a different WAS in a Web Dynpro based application running on a different WAS.
Thanks and Regards,

I found at "How to Use the Web Dynpro Content Administrator.pdf" a good place to look for my mistake. But a big question appeared:
Once I get in the Web Dynpro Content Administrator and found my deplyed app I found this two JCo:
WD_MODELDATA_DEST
WD_RFC_METADATA_DEST
Witch status was a little grey diamond, or something like that. ¿Can somebody tell me what is happening with this Jco?
The page 27 of the pdf mentioned before, was different in my IDE SAP Developer Studio, the only option, by default, that give me was to choose between WD_MODELDATA_DEST and
WD_RFC_METADATA_DEST. I have two fields that must be fill to pass to the next dialog box or finished the creation RFC model.
Thanks a lot !!!

Hi,
In NWDS, you should have defined your own JCo destinations when creating your model. For example:
- WD_<yourApp>_MODELDATA_DEST
- WD_<yourApp>_RFC_METADATA_DEST
Then in the Web Dynpro Content Administrator, you must create them, ie specify connection types, connection parameters...
For this, choose the button Maintain JCo Destinations, find the connetions you've created in NWDS and click the button Create. Just follow the steps of the wizard, and you're done!

What to after Creating a Web Dynpro Application

Hello,
My question might a little stupid so please don't mind. I have created a web dynpro application where the user enters a sales order no and the output of is shown in an ALV format in web dynpro. My question is what next, I mean how do I give it to the users to use it. They should only be given the URL which is generated?
Also if i directly enter the URL it asks me for my Username Password of the SAP Logon. can this be avoided like some reports where one cant make any changes in the database just get the output this Username Password thing be skipped

Hi.,
You can create a Transaction for Web Dynpro Application to dispaly in browser as well as in SAP GUI.,
check this: can we create a tcode for webdynpro application?
else you can integrate it in Portal by creating iviews.,
check this article: [How to integrate Web Dynpro ABAP in Portal|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/008fc414-997f-2e10-3899-fd895ec8eb5e]
hope this helps u.,

Need to create a Web Dynpro Application for SRM Portal

We need to recreate the start page for SRM Portal - (Supplier Self-Services) - without any images (as was delivered out of the box) - basically we need to break it down into 4 iViews: All Purchase Orders; All Sched Agreement Releases; All Invoices and Credit Memos; and Account History. All these iViews contains links.
How would one create a Web Dynpro Application to create the above iViews?

Display HTML stream in Web Dynpro application

Hello,
Sorry, I am new to the Web Dynpro environment, so this might seem like a stupid question.
How can I display streaming HTML content in a Web Dynpro application. The IFrame element only seems to allow you to point to a URL. In this case, I am receiving an HTML stream back from an R/3 system via a BAPI call.
Thanks very much.

Hi
As per your question, I understand that HTML output is getting generated through a R3- Bapi call. Fine, create a model with the data binding to the context to some text view. Simply create view with the relevant UI element through which you want to exhibit the data and call the R3 call through your model. instead of a HTML output, you will get your data in the view.
you may not get the exact format / style of the html output.
Otherwise, directly HTML content cannot be shown in webdynpro. You need to have some UI control to take its content.
Or else, you can go in for j2ee stack and end up with a java based appl, use a simple jsp and get the output!
if you have any specific queries do let us know
hope this helps you
thanks
