Using Web Dynpro WDUrlGenerator from within J2EE Application deployed on NW

I have two applications deployed on a NetWeaver Application Server 2004s.
1. A Web Dynpro application.
2. A J2EE Application
What I want to do is to be able to build a url to the Web Dynpro application from within the J2EE application. Obviously the problem is using Web Dynpro classes within the J2EE application.
So I edited the Java Build Path of the J2EE application to include the werbdynproservices.jar file and exception.jar files by extending ECLIPSE_HOME variable in the libraries section. I also checked them in Order and Export. I verified the built .war file and it does contain the two .jar files.
This was sufficient to get my project build and deployed, however the servlet in my J2EE application shows NoClassDefFoundException when I run it. My guess is there's more I need to do to get the WDUrlGenerator to run in my J2EE class.
Is this possible or is there a better way? I am trying to avoid the client having to modify a web.xml for each depployment.
Thanks in Advance.

This looks like what I want, but I am unable to test it.
I found the application-j2ee-engine.xml file under the <project-root>/gen_wdp folder. I then attempted to open it with the SAP EARDD editor. It opens with the Source tab selected. If I try to click the General tab I get an error saying:
"The source page has errors. Other pages cannot be used until these erros are corrected."
I see nothing wrong with the XML document. It's source is here:
<?xml version="1.0" encoding="UTF-8"?>
<application-j2ee-engine>
    <provider-name>local</provider-name>
    <modules-additional>
    <module>
      <entry-name>EVENTS_WorkflowNotification.wda</entry-name>
      <container-type>webdynpro</container-type>
    </module>
</modules-additional>
</application-j2ee-engine>
When I deploy the application, everything works fine. I was going to edit the XML document by hand, but of course there is no DTD listed so I don't know what's supposed to go in there without the Editor doing it for me.
Getting closer. Thanks so much.

Getting and Printing A PDF Document From R/3 Using Web Dynpro

I would like specific information on getting and printing a document residing R/3 using web dynpro. My environment is Netweaver 04s SR2, an it will not include ITS or the ABAP stack. It connects to remote R/3. I will not be using Adobe Interactive Forms.       I only need get/render/print the doc. My question is in 3 parts.
1) Getting the PDF from R/3
     a) In terms of the RFC ABAP module, how should it return the pdf (a table?)
     b) How should the document be stored within the Component Controller context
         for display.
2) Converting the R/3 returned binary into a form that is renderable within
    Web Dynpro. (Does the Form UI Element Require it to be converting and if so
                          what is the best way to do this)
3) Printing the PDF from the corresponding iView in the portal. (If I am using the
    form ui element to display it, how can printing be initiated in the portal)
Thanks

Hi,
In webdynpro there s a fecility to convert the general data to PDF by uisng th InterativeForm UI Element.
This for u need to do the following things.
1. Need to configure the ADS(Adobe document services) in your VA(Visual Admin).
2. Once ADS is configured we can utilize the UI element Interactiveform It has contain the Adobedesigner by using this we can design the PDF and binding with the model nodes.
3. Develop the Function module in the r/3 side and import into WD side and those are created as Model nodes and we canutilize in the 2 step.
4.When u run the application u can display the pdf with how u design ur PDF form.
This is generally doing the PDF by using PDF.
Or do u think any other way post ur issues.
Thanks,
Lohi.

FETCH DATA FROM ORACLE DATABASE USING Web Dynpro

I want to fetch data from ORACLE database using Web Dynpro.How can I do this?

1) Are you sure that you get no results? It sounds like you are having name resolution issues, which would imply that you should be getting an ORA-00942 error indicating that the table doesn't exist (or that you don't have access to the table). If you are not seeing this error, I would tend to suspect an overzealous exception handler.
2) What database account owns the table? What database account is your ASP.Net application using to connect? Assuming these two accounts are different, your application would either have to
- Explicitly prefix the table name with the schema name
- Have a public or private synonym that maps the table name to the fully qualified identifier schema_name.table_name
- Issue the command ALTER SESSION SET CURRENT_SCHEMA = <<schema name>> in each session, in which case all queries in the session would use the specified schema name as the default if no schema name is prefixed.

How to create a user in UME Database using web dynpro java custom application

Can you please suggest me how to create a user in UME Database using web dynpro java custom application.
My Requirement is user can register his/her user id in SAP Portal 7.3 UME database.
Please suggest me.
Thanks and Regards,

Hi Amit,
Generated Documentation (Untitled)
This is what you're looking for, there's no real cook-book -- though Amey mentioned there might be some material on SDN, perhaps some tutorials.
You should be looking into com.sap.security.api.IUserFactory, methods newUser(String) which gives you and IUserMaint and commitUser(IUserMaint, IUserAccount) -- IUserAccount can be obtained using com.sap.security.api.IUserAccountFactory, method newUserAccount(String)
Hope it helps,

Reading HTML Content using Web Dynpro ABAP

Hello,
I was wondering if it is possible to read the content (HTML) behind a given URL using Web Dynpro ABAP. If so, are there any functions available to parse the HTML ? I have been asked to develop an application that requires going to a URL, reading the content, and formatting a table from that content for presentaion within Web Dynpro ABAP. The HTML of the URL is nothing more than a "Table of Contents" to existing documentation ( Word Documents )
Thank you for any help / advice you can provide
Larry

You can get the HTML returned in a table using fm RSFO_HTML_REQUEST2.
Once you have that, you can convert it to a string using any number of methods. CL_RSR_WWW_RENDERER=>TABLE_TO_STRING should work fine.
One option for parsing it would be to get it converted into an iXML object, but you might have to do quite a bit of manipulation first depending on what the html looks like. You can see more info here on iXML classes: [http://help.sap.com/saphelp_nw04/helpdata/de/86/8280ba12d511d5991b00508b6b8b11/frameset.htm|http://help.sap.com/saphelp_nw04/helpdata/de/86/8280ba12d511d5991b00508b6b8b11/frameset.htm]
Otherwise I would just make use of find statements with regex patterns to sort through the html.

Moving Local Web Dynpro project from Dev to Prod

Hi,
i have a scenario where there is a small application to be developed. And m the only developer to work on it.
I need to a create local web dynpro project for the same and deploy it to the deveopment server. and test it here. However, the client for whom i am developing this service, is based somewhere else. How do i deploy this local application on his production server?
I dont have JDI architecture here. Can i achieve this without JDI? and How? Which is more feasible - using JDI or not in my case ?
Regards,
Apeksha

Hi,
Genrally, it is recommended to work with JDI. But, as you said you have only project that needs to be deployed then you can change the server settings in your NWDS and make it point to the production server.
Windows>Preferences>SAP J2EE Engine--> <details of your remote production server>
NOTE: You should have sdm password to deploy this applicaiton.

Creating a Sales Order using Web Dynpro

Hi SDN,
I want to create a Sales Order using Web Dynpro application. For that i have used "Bapi_Salesorder_Createfromdat2" as a adaptive RFC model. Every thing is fine and i could able to create a sales order for a single line item. But my intension is to create a sales order for multiple line items. So in the "Intialview" i have used a "Table" UI element to pass multiple line items. When i execute this application i could pass only single line item from this table. The table UI contol is not allowing to enter the second line item in the second row of the table. Can any one suggest me to solve this problem.
Thanks in advance.

Deletion of data of R/3 table using Web Dynpro

Hi Experts,
I have to delete some records from R/3 table CATSDB using Web Dynpro form. I am using BAPI_CATIMESHEETMGR_DELETE for this purpose. Can you please let me know the steps to accomplish this exercise.
I have displayed the records of CATSDB using one custom made BAPI. Using this BAPI, I am able to display the data. I have created one button called "Delete Data" button on the form. I have called BAPIs using following code:
public void onActionDeleteData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionDeleteData(ServerEvent)
    wdThis.wdGetTimesheetCompController().executeBapi_Catimesheetmgr_Delete_Input();
    wdThis.wdGetTimesheetCompController().executeBapi_Transaction_Commit_Input();
//@@end
However, when I am selecting the record and trying to delete the record, record is not getting deleted. Can you please help me in resolving the issues? What is going wrong?
Regards,
Brian

Hi Ashwani,
I have checked the BAPI - BAPI_CATIMESHEETMGR_DELETE. I am unable to delete the record using even R/3 screen. For deleting the record, I have to provide following four parameters:
PROFILE, TESTRUN, RELEASE_DATA and AGENT.
I don't know what should be the value of TESTRUN, RELEASE_DATA and AGENT. I know only the value of PROFILE. From ABAPers, I have come to know that in order to delete the reccord I must provide the value of COUNTER. However, the BAPI, BAPI_CATIMESHEETMGR_DELETE is not asking me to enter the COUNTER.
Can you please let me know how to delete the record from BAPI using R/3 screen. After that I will try to delete record using Web Dynpro application.
Regards,
Brian

Making selective fields editable in adobe form [using web dynpro]

Hi,
I have displayed an adobe form using web dynpro application. But I have to make certain fields (not all fields) on this adobe form editable. I dont want to make this adobe form interactive because I dont have to save any data in database. The data entered in the editable fields will be saved as a pdf.
What I did so far:
1) The fields which I want as editable, I have given there type as "User entered/ optional" & for rest of the fields I have given type as "Read only".
2) In web dynpro, I have enabled the adobe
3) This is not making the fields editable.
4) If I write the following code in my webdynpro method WDDOMODIFYVIEW, then my data coming from adobe is not getting displayed even though the fields get selectively editable.
*data: LR_INTERACTIVE_FORM type ref to CL_WD_INTERACTIVE_FORM,
*LR_METHOD_HANDLER type ref to IF_WD_IACTIVE_FORM_METHOD_HNDL.
*check first_time = abap_true.
*LR_INTERACTIVE_FORM ?= VIEW->GET_ELEMENT('adobe').
*LR_METHOD_HANDLER ?= LR_INTERACTIVE_FORM->_METHOD_HANDLER.
*LR_METHOD_HANDLER->SET_LEGACY_EDITING_ENABLED( abap_true ).
Any inputs regarding this??
Thanks & Regards.

Hi,
Like I had mentioned using the following code in my webdynpro method WDDOMODIFYVIEW, my data coming from adobe form was not getting displayed even though the fields get selectively editable.
*data: LR_INTERACTIVE_FORM type ref to CL_WD_INTERACTIVE_FORM,
*LR_METHOD_HANDLER type ref to IF_WD_IACTIVE_FORM_METHOD_HNDL.
*check first_time = abap_true.
*LR_INTERACTIVE_FORM ?= VIEW->GET_ELEMENT('adobe').
*LR_METHOD_HANDLER ?= LR_INTERACTIVE_FORM->_METHOD_HANDLER.
*LR_METHOD_HANDLER->SET_LEGACY_EDITING_ENABLED( abap_true ).
So I kept this code & I also kept the Interface type "ABAP Dictionary based".
Additionally in Webdynpro, I used adobe form generated FM to get the adobe content & passed it to the "content" parameter of my adobe component in webdynpro.
Thanks & Regards.

Retriving data using web dynpro

I want to make simple application whic stores data and retrive specified fields using web dynpro. can anyone provide tutorial link to do this

Hi,
The solution to this is very similar to the reports that we write.
1. Create a context node from the dictionary element in the view of the webdynpro component.
2. Now you may be displaying/editing this data in the form of a table in the view layout. For this create a table in the layout and bind the fields of the context to the node you created from the dictionary table in the context.
3. In the layout you also want to have a button SAVE. on the event of this button. Write the code from code wizard where in
a. Read the context of the dictionary table from the context.
b. call method
CALL METHOD lo_nd_group->get_elements
RECEIVING
set = lt_ddictable.
c. update the database table using the internal table lt_ddictable.
Hope you find this helpul.
