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

How to add new class to existing DC (Web Dynpro project)

Hi,
How can I add new class to an existing DC (Web Dynpro project)?
I tried adding it using File - New - Other - Java - Class, but after a build of the DC the new class (and its contents ) was completely removed.
Then I created a new DC (java project) and created a new class in that DC. This went fine, but I got into problems because of circular referencing between the new & the old DC, so no build was possible.
This can't be difficult, does somebody knows how to do it?
My temporary solution is to add the classdefinition to an exisiting .java file. Very ugly.
Thanks,
Jeroen

Hi Jeroen,
where did you create the class? If the *.java file is placed in the src/packages folder it should not be deleted by a build. (I suspect you created it in the gen_wdp folder?)

Marc

How to make use of Portal service in the web dynpro application

hi
I have some portal service and how to use that in the web dynpro application.
and also what is the main diff between Portal Component and web dynpro application.
do we required portal to run web dynpro application.
thanks
mmukesh

Hi,
>> I have some portal service and how to use that in the web dynpro application.
Yes. U can use Portal service in webdynpro. Check the link given by subathra.
>> and also what is the main diff between Portal Component and web dynpro application
Portal Components are components designed to run in portal server while webdynpro application can run in J2EE WebAS.
>> do we required portal to run web dynpro application.
No for general cases. Just WebAS is sufficient to run webdynpro appl. But if u use portal service in ur webdynpro appl, then make sure both (portal service and webdynpro appl) run on same J2EE engine. That is mandatory.

How to link the ALRTINBOX in a ABAP Web Dynpro application?

How can I link the ALRTINBOX window in a web dynpro application view?

Hi Rahki,
The status of what?
There are traffic light icons that you can use, or you can set the cell design (which changes the background colour of a cell (if you are in a table).
I often use this to indicate on a review step whether a cell/row has been inserted, modified or deleted from a table.

Using a Deployable Proxy in a Web Dynpro Application

Hi,
We have a Web Dynrpo application whose model is built from a set of Java business objects (POJOs.) These Java business objects currently make calls to a back-end R/3 system using JCo. We would like to provide the ability to allow the calls to be made over Web Services to the back-end system.
To call the RFMs as web services we have created a Deployable Proxy project, added the proxy as a public part, then referenced that public part in the web dynpro application. At this point we can write code to call the web service that looks something like:
InitialContext ctx = new InitialContext();
Object serviceObject = ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSService service = (Z_MRDM_GET_PLANTSService)ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSPortType port = service.getLogicalPort();
Z_MRDM_GET_PLANTS plantParameter = new Z_MRDM_GET_PLANTS();
plantParameter.setI_PLANTID(id);
plantParameter.setI_PLANTNAME(name);
Z_MRDM_GET_PLANTSResponse response = port.z_MRDM_GET_PLANTS(plantParameter);
MT001W[] plantArray = response.getET_PLANTS();
The problem is that when I call looup to retrieve the service implementation I get a ClassCastException.
The tutorials for using a proxy in web dynpro all assume that the web service is what the model is based upon but that's not possbile for our scenario we need to call the proxy from the business objects which are the basis for our model.
According to the help documentation for consuming a deployable proxy in a JSP page:
<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm">http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm</a>
It discusses adding JNDI mappings. Is this what's needed for the reference to work in a Web Dypro application too? If so, how would one add the JNDI mappings references to a Web Dynpro application?
Many thanks!

Hi Dheeram,
I'm not certain about JSPDynpage specifically, but in a general J2EE Enterprise Application project you can add a reference to the application-j2ee-engine.xml file. For example here's the content of an application-j2ee-engine.xml file that references a proxy:

How to display the error message during the web dynpro application runtime

hi,
    I'm a java developer,During i 'deploy and run ' a web dynpro application on server-1,if the application have some runtime errors. there are displayed many infomation about the runtime error,such as exception track,etc.
    But when i do the same on server-2,there just show something like:
            500   Internal Server Error
                                SAP NetWeaver Application Server 7.00/Java AS 7.00
            Failed to process request. Please contact your system administrator.
but the server-1 will stop the j2ee engine.
how can do i make server-2 show detail error message as server-1. when i debug web dynpro application need these infomation.
Appreciate your inputs...
(Note:server-1 and server-2 have same software version)

The Sap-Notes 962319:
1. Check in the Visual Administrator, "Licensing Adapter" -> "General" -> "SystemType" !
If it is set to "DEVELOPMENT_MODE", verbose error messages are shown.
If it is undefined, proceed with the next step.
If it is set to something else, only exception IDs are shown. In this case the only chance is to search for this exception ID in the default traces.
2. If the system type is undefined, then in the Config Tool "Configurations" -> "webdynpro" -> "sap.com" -> "tcwddispwda" -> "Propertysheet default" -> "DevelopmentMode" is evaluated. If it is "true", verbose error messages are shown.
3. If verbose error messages are required but still the short version is shown, you probably face an error message that is not raised by Web Dynpro but by other components of the NetWeaver. In the Visual Administrator set "Properties" -> "HTTP Provider" -> "DetailedErrorResponse" to "true".
4. In addition to the error page shown in the browser or client, important messages - including error messages and stack traces - are written to the log and trace files, e.g. to the default traces usr\sap\<SID>\<instance>\j2ee\cluster\server<number>\log\defaulttrace.trc.<number>.
a) In some cases, when an exception ID is included in the error message, the detailed error message can easily be retrieved in the log file.
b) When no exception ID is given, you have to search for the detailed error message in the log specifying time stamp and/or user ID.
Always consider restarting the system after making changes on the settings.
It is not recommended to switch the "SystemType" to an inappropriate value just for viewing verbose error messages. The system type potentially affects framework, applications and licensing in an perhaps unintended way.
In the past there was no distinction between different system types regarding error messages. For security reasons this distiction has been introduced. It is not intended to show stack traces in non-development systems in the future. SAP does not provide workarounds or patches to enable such a behaviour again.

How to use the catalog in our own Web Dynpro program?

Hi Expert,
How to access MDM catalog and bring the product data back to a our own Web Dynpro program?

Hi Masa,
The Catalog Search UI of SRM that is referred to as UI as aforementioned is a page which is capable of the selection of catalog items is linked from the shopping cart creation.
Our biz requirement content two scenarioes to processing the purchase requirement.
A. Create shopping cart via the catalog (PR) --> SRM PO Process --> SUS(PO and Invoice)
This is the standard SRM purchase scenario and we have already implemented that.
B. Create a requirement document via the catalog (This document is same with the SC but very simple, and we create this function by the own web dynpro program) --> transfer the requirement document to other purchasing system(none SAP) in our intranet.
So the key problems we faced are below:
1. How to connect to the catalog search UI from our own web dynpro program.
( If we connect the catalog via the MDM ABAP API, that will make the catalog serach UI could not be used;
Also it has been failed to simulate the function of SC's connection to the catalog;
So we decide to link the catalog serach UI via the URL, the linkage is "http://<J2EEserver:J2EEport>/SRM-MDM/SRM_MDM?sap-locale=EN&HOOK_URL=&mask=&namedSearch=General&username=&password=&catalog=<Repository Name>&server=&datalanguage=EN". )
2. How to transfer the catalog item data to our own web dynpro program.
If we link the catalog search UI by URL, we can not find any good method to transfer the catalog item data to our own program.

How to set mandatory a InputField in standard Web Dynpro component?

Hi guys.
A very weird thing is happening. I am trying to validate that a non-mandatory STANDARD input field (COST_ASSIGNMENT) does not to be empty. This input field belongs to GENERAL_DATA_VIEW, FITE_VC_GENERAL_DATA WD component. The entry fields at screen belong to this GENERAL_DATA_VIEW, but navigation is allocated in buttons that belong to another component (LAYOUT_VIEW in the FITV_FPM WD component). All the views and components are standard and they seem to be in the same screen from user's point of view. I was able to put my own code at WDDOAFTERACTION method in LAYOUT_VIEW to raise an error message.
Incredibly, my error text message appears in the MESSAGEAREA, and the UI components from GENERAL_DATA_VIEW are rightly still in the screen waiting for user answer since I set CANCEL_NAVIGATION = 'X', but the UI components from LAYOUT_VIEW (the buttons with navigate functions) changed like they had accepted my entry in spite of I set the code in this view. In fact, below my error text displayed, there is other (success) text which communicates "Standing approval for business trips exists" with a green tick.
The success text should not be displayed since I raised an error message, even after (I think so) the system created the success message. I suspect that the standard positive message with the green tick indicates that my error is being taking into acccount by the system to be displayed but the LAYOUT_VIEW UI components dont stop navigation and the data is wrongly saved from the code where the success message was generated.
I think there would be another way to define an standard inputfield mandatory, but I dont know how to do it. Do you know that? I really appreciate all help. Thanks

hi,
just make the input feild as mandatory in properties and use the following code.
data:
lo_view_controller type ref to if_wd_view_controller,
lo_dyn type ref to cl_wd_dynamic_tool.
Create Object
create object lo_dyn.
data lt_messages type lo_dyn->t_check_result_message_tab.
Get view controller reference
lo_view_controller = wd_this->wd_get_api( ).
Call Method to verify the element has the value or not
call method cl_wd_dynamic_tool=>check_mandatory_attr_on_view
exporting
view_controller = lo_view_controller
display_messages = ABAP_TRUE
importing
messages = lt_messages .
endmethod.

Custom seach help for standard field in Web dynpro application

Hi All,
I have a requirement in SRM portal where in I have a to add a custom search help to the 'WBS_ELEMENT' field in the the 'ACCOUNT ASSIGNMENT' tab of the Shopping cart creation screen with some input parameters on the search help.
As the SRM Shopping cartcreation screen is a standard web dynpro application.
Can anyone help me in this regard for addition of search help for a field with some custom fields in the Search help screen.
Any inputs will be very helpful.
Thanks in advance.
Regards,
Ahmed.

Hi Ahmed,
If it is an standard application then you will have to do ENHANCEMENT in the component. And for using customised value help you will have to declare attribute in CONTEXT and dynamically change the binding of the Value property of UI element inside post-method of WDDOMODIFY. You can create your own customised value help for newly added attribute.
Thanks,

How to use a cascading LOV as a Web Services Consumer?

How to use a cascading LOV as a Web Services Consumer?
We are trying to populate a prompt programmatically.
Our program is a Web Services Consumer.
As an example we use Island Resorts Marketing
The cascading LOV for City is
Country -> Region -> City
The City object is key-aware to the customer table
The query is
Customer | Revenue
(where) City = [prompt]
In order to make the key-awareness work, we must select the value (rowIndex) from the LOV
When we run our program below, the LOV for City is not populated, as expected since we must first select the Country, then the Region.
The code snippet below shows that the LOV for Country is populated. We have no idea how to go from there.
Any hint will be immensely appreciated.
Let us know if anything is unclear in the code.

How to change the Portal Password using a link from Web dynpro application

Hello Everybody,
I have a requirement to change the user password from a web dynpro application which is available on a mobile device. Firstly User will log into the portal through a mobile device and after getting authenticated user will be redirected to the mobile application. Within this mobile application there will be a link to change the login password(Portal login). Can somebody tell me how can i change the portal login password from a link available within the mobile application. Looking forward for a suitable reply.
Thanks to all,
Regards,
Saby.

Hi Maksim,
Thanks for your reply..but i would also like to know can we directly use the Change Password Iview "persoUserPassword" from the portal. Can i directly Pass the URL of this iview from the portal to a "Change Password" link in the web dynpro application, so that when the user click this link he should be able to see this Iview on his/her mobile device and should be able to change the password from there. But i dont know whether this iview will appear properly on the mobile device or we have to have a custom web dynpro application for this purpose...Please reply with a suitable answer.
Thanks in advance.

How to use the set functions effectively in webi ,please let me know with detail

how to use the set functions effectively in webi ,please let me know with detail

Hi,
we use use set functions on heirarchies with aggregate functions mostly .
If you include member_set, Min returns the minimum value of the aggregated data for all members in the member set.
Member_set can include multiple sets separated by semicolons (;).
The list of member sets must be enclosed in {}.
If the member set expression does not specify a precise member or node, the hierarchy referenced must be present in the table, then the member set expression references the current member in the hierarchy in the table. If the hierarchy is not in the table, the function returns the message #MULTIVALUE.
Eg .
1)     Ancestor
=Sum([YTD] ; {Ancestor([Test Hierarchy];2)})
2)     IsLeaf
=[Test Hierarchy].IsLeaf
You can use this function when you want to show your Measure only at lower level .
3)     .Depth
=[Test Hierarchy].Depth
This is also function used with hierarchy to find Level of Members .

How to make changes to stdandard web Dynpro applications used in ESS

Hi all
I have uploaded the standard ESS Business Package,
now the requirement is to change some features in the web dynpro application in it.How do I go about it?
Regards
Mansoor

Even though those are tow different tabs, but both are under one view controller.
So create a node and pass the data.. so data will be available to both tabs.
View controller is local controller
component controller is global controller.
if you want to access the node outside your view then declare the node in component controller.

How can I copy a standard Web Dynpro Abap?

I have to make changes to some texts in a standard web dynpro: FITV_FPM_START. One of the texts is "Description" ("Descripción" in Spanish), which seems to be protected in the OTR. So the only option I see is to copy the whole Web Dynpro, locate the component in which the text appears, and replace it for the new one. If there is a simplest way I'd be glad to know...
I've copied the Web Dynpro and then all the Web Dynpro Applications, with their parameters and so on.
When I verify one of them most of the things are not appearing on the screen. I can only see the buttons. What have I missed to copy?
Thank you in advance.

Hi,
If you just want to change some OTR text, I do not think that you need to copy the whole application. Just get the alias for this OTR text. (I just tested changing an OTR text from SAP...it did not ask me for any keys...so I hope it will be alright in your case as well....)
To get Alias, go to your webdynpro application, than go to menu "Goto", select "online text repository browser", than double click on the OTR text you want to change the text for. This will open up a new window...the first line is Alias Name.
take this Alias Name....go to transaction SOTR_EDIT
on the screen which shows up, you have following
Language: Pick English here
Text: *
Alias: here put the alias name you found
Concept: leave it blank
click on display.
Now on this screen go to the "EDIT" menu -top of the screen-where you also see system and help menu. Follow the following path:
Edit->Context->Change
As soon as you will click on Change....you will see a pop up coming up with following fields:
Country:
Industry:
close this pop up box without filling out anything there....just click on red x and close this pop up box.
After you close the pop up box you will find that the "Language" field is open for editing....
In this field choose the language you want your Alias to be translated into or leave it as English if you want English..
In the text field...type in your new text....
Save your work...
That is all...no need to do anything else.....
you can check if your Alias is being translated...
go back to transaction SOTR_EDIT...and than choose language and put in the Alias Name
you should see your changed text...
I guess you are copying a FPM application...if that is the case, than you might be missing the configuration for that application...that is why you see things missing there.... try to search in forum for FPM guide....
I hope this helps...
Thanks...
