Access KM predefined property values from a Web Dynpro application

Hi,
I am trying to build a custom search interface in Web Dynpro which leverages the KMC Indexing and Search services.
In this interface I would like to display value lists of predefined properties in KM (created using the Property Metadata Service) and bind each predefined property's value list to a checkbox group UI element.
Which KM API should I use to retrieve the values of a specific predefined property ?
When using the standard flexible user interface in the portal this can easily be achieved through configuration, but now I would like to know how to achieve this in Java code.
Thanks in advance for your input.
I have some idea on how to get the propertymap from a resource, but how can I access the metadata of a predefined property in KM directly ?

Hi Theo, i'm working on something like this, i have a WD application that is accessing Km through a Webservice, on the webservice ejb i have this problem:
IResourceFactory resFactory = ResourceFactory.getInstance();
IRepositoryServiceFactory serFactory = resFactory.getServiceFactory();
IPropertyConfigurationService propConfigService = (IPropertyConfigurationService) serFactory.getService("PropertyConfigurationService");
IMetaNameListIterator i = propConfigService.getMetaModel().nameIterator();
     while (i.hasNext()) {
     IMetaName metaname = i.next();
     if ( metaname.getDocumentPatterns()!= null){
     propertyData.setId(metaname.getName());
     propertyData.setName(metaname.getLabel(locale));
     propertyData.setNamespace(metaname.getNamespace());
     propertyData.setDescription(metaname.getDescription(locale));
                propertyList.add(propertyData);
On this line serFactory.getService("PropertyConfigurationService") i get the following error on the trace:
#System.err#sap.com/KmmsListEAR#System.err#Guest#2####30a27fa0cbfa11dbace30018de0545f1#SAPEngine_Application_Thread[impl:3]#Error##Plain###Configuration Framework error: unable to create an IConfigClientContext instance from an EP5 userInitialConfigException: The configuration service locator could not be initialized for any of the environments.

Do you have any idea of how to solve this? or if you accomplished in a different way, can you guide me a little bit.
Thanks in advance Theo

How to pass the values from the Wb Dynpro Application to the SAP Backend ?

Hi All,
Good morning..,
I have scenario like:
I want to pass the values from the web dynpro appication to the SAP Back end R/3 Table. IN backend the RFC is writtn to accept the structure input from the Webdynpro.
Upto know I imported the corresponding RFC and maaped to the View.
How to proceed with the coding to save the data...
PLease suggest...
Regards and Thanks in Advance,
CSP

Hi Pradeep
Steps:
1. First create an instance for bapi and bind the instance to the bapi node.
Z<bapi name> zb=new Z<bapi name>();
wdContext.nodeZ<bapi name>. bind(zb);
2. Then if u have the import parameter u have to set them by using
    The instance of the above bapi.
    Zb.set<import parameters>;
3. If the bapi has a table parameters then the structure for the table parameters will also be imported
   In the model class.
4. Set the table parameters by creating the instance for that structure and using this instance set it.
   Z<Struct>itm tab=new Z<Struct>();
   Tab.set<table parameters>
5. Then add the structure instance to the bapi instance.
    Zb.add(Tab);
6. Then Execute the bapi after setting the import parameters.
7. If there is any export parameters, then get the values after execution.

How to Debug a BAPI from a Web Dynpro application

I have a Web Dynpro application calling a BAPI, and I would very much like to see what data the Web Dynpro application is passing into the BAPI, and then debug the BAPI.
Is there a way to do this? I'm wondering if it is possible to somehow set up the ABAP stack so that on receipt of the BAPI call, it appears on the tRFC queue waiting for execution.
However it is done, I need a way to step through the BAPI on the ABAP stack.
BR,
Tony.

Hi Anthony,
The ABAP runtime environment contains various tools that you can use for analysis purposes, such as for debugging source code. All source code written for Web Dynpro applications in ABAP can normally be tested using the debugger.
To allow it to test other Web Dynpro-specific program entities too, the debugger has been equipped with a special enhancement. In the phase model in the active application, you can typically see the following information at various points in time:
-The structure of the content of the current controller,
-The properties of the UI elements in the layout of the current view
-The currently instantiated component usages
Starting the Debugger
The functions for debugging Web Dynpro entities are embedded in the new debugger. You therefore need to have selected the new debugger in your Workbench settings.
Selecting the New Debugger
1. In the menu, choose Utilities -> Settings.
2. A dialog box now appears that contains two nested tab page areas. Choose the parent tab page ABAP Editor.
3. The settings for ABAP Editor always open with the content of the child tab page Editor. Here, select Front End Editor (New).
4. Now switch to the Debugging tab page in the ABAP Editor settings and select New Debugger.
5. Save your changes and close the dialog.
Starting the Debugging Process
To run an application in debugging mode, you first need to set an external breakpoint in display mode in one of the methods in the component.
Now start a test run of the application from ABAP Workbench as usual.
The method in which you set the breakpoint depends on the purpose of the test run. To debug a view, for example, it is best to set the breakpoint in method WDDOMODIFYVIEW. Provided that the context of the view controller is not filled using a supply method, the view is fully instantiated in the phase model at this point in time.
Selecting the Web Dynpro Tool in the New Debugger
When you start the application, another session opens automatically for the debugger. If you have not yet saved any personal settings with regard to the layout of the debugger, the Editor tool will now appear on the left, with the Display Variables tool on the right.
1. Select one of the three desktops in order to reconfigure it for debugging the Web Dynpro application (see Designing Work Areas).
2. The right-hand edge of the debugger window has a bar of function icons. Choose the Replace Tools icon:
3. In the next dialog box (New Tool) open the lowest node (Special Tools) and choose Web Dynpro.
4. Confirm the dialog box.
On the right of the debugger desktop, you will see that the previous tool has now been replaced by the Web Dynpro debugger. You can save this setting for future debugging activities. To do this, choose Save Layout In the debuggers general toolbar.
Thankyou,
Ramganesh.

Whatever value you have, you need to put into string format anyway.
Just declare a temporary string field and move yoru carrid value to it before calling the append_field_url method.
From application 2 you read the URL parameters using the start plug of the window.

How can I create a web Service from my Web Dynpro Application ?

Hi,
Kindly let me know How I could create a "Web Service" with my Web Dynpro DC project.
Awaiting your responses.
Regards,
Mahesh

Hi Mahesh,
You can use the web services by creating the Model in web Dynpro
And if you want to publish your own web service then you have to create a EJB module and publish as a web service.

Unable to access PCD's role properties from Java Web Dynpro (Access Denied

Using the IPcdContext to access the portal roles does not produce the required list of roles due to the following error
Access denied (Object) .....
This occurs once I try to use the lookup() method
I have tried security zones, adding sharingReferences and permission, but no luck.
I have searched the SDN but again whatever I found still gave the same result. I now think that it's a configuration settings rather than code.
Sample code
Hashtable env = new Hashtable();
env.put(Context.SECURITY_PRINCIPAL, strCurrentUser);
env.put(Context.INITIAL_CONTEXT_FACTORY, IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
//DirContext ictx = new javax.naming.directory.InitialDirContext(env);
// InitialDirContext ictx = new InitialDirContext(env);
InitialContext ictx = new InitialContext(env);
lookupObject = "portal_content";
IPcdContext myPcdContext = (IPcdContext) ictx.lookup(lookupObject);
Any suggestion will be appreciated

The only thing I see different as per this [document |https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6112ecb7-0a01-0010-ef90-941c70c9e401] is following line of codes. Check if adding it resolves the issue:
env.put(com.sap.portal.directory.Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_SEMANTICS);
lookupObject = "pcd:portal_content/"

Calling a Standard SAP transaction VA03 from another web dynpro application

Hi All,
I have a requirement wherein I need to call the standard SAP transaction VA03 whenever a sales order is selected in some other we dynpro application so that the sales order gets displayed.
No regarding usage of OBN for the above functionality I have certain queries:
1. In order to call VA03 do I need to create a transactional iview for it or is there any direct method.Also how to pass this sales order number as parameter to the T.Code.
2. Can we use standard business object BUS2032 for OBN or a new Business object is created.What exactly is the purpose of these standard business objects in portal and when should they be used.
Thanks in advance
Aman Gupta

Hi Aman - Do you have a portal team in your project or you have to create the IVIEWS yourself?
I do have a portal team and I dont know how they create the IVIEWs but for example, I will go to my portal team and I will ask them to create an IVIEW for TCODE VA03, they will created and they will tell me the input parameters they entered for the IVIEW so I can call OBN and display in webdynpro.
SAP in SRM has webdynpro e.g. for BUS2121 and they have an IVIEW already implemented in the portal context pointing to the webdynpro of BUS2121 so we can used the IVIEW by calling OBN and passing the parameters; in my case the object_type will be 'shc' and the operation will be 'display' and the paremeters itab will be the GUID of my shopping cart, that way the OBN can understand which Shopping cart open and in which operation mode.
I also did something like your requirement, I need it to display a specific case in Records Management but SAP has a standard IVIEW for records management 'RMREGEDIT' that didn't work for my requirement so I went to SE38 created a program that displayed the case based on GUID and I created a TCODE of my custom program. Portal team created a custom IVIEW of my custom TCODE and they told me the input parameters to call the TCODE in OBN and I pass in the itab parameter the GUID of the case using the FM that I post before.
The action to call the OBN is in the event handler ON_CLICK of my ALV and the action is getting trigger when the user actually clicks a HYPERLINK in the ALV.
Hope this helps you!
Please feel free to ask me more details if you need.

Call ESS FPM CATS Working time application from non FPM web dynpro application on click of button

Hi,
My requirement is to launch ESS Working time application HRESS_AC_CATS_1 from custom web dynpro application.
ESS CATS working time application is configured in LPD_CUST launchpad.
I tried using method cl_hr_navigation_services=>navigate in my custom web dynpro but it did not work.
Regards,
Ibrahim

In case you want to use Launchpad, you can use ABAP class CL_APB_LAUNCHPAD_API. If choose not to use Launchpad, you can use method CONSTRUCT_WD_URL of ABAP class CL_WD_UTILITIES to generate the URL. Specify Web Dynpro application and Web Dynpro Configuration as parameter. Finally create an external window using method CREATE_EXTERNAL_WINDOW that points to that URL.

Java dictionary database table in web dynpro application

Hi,
I want to access java dictionary database table in my web dynpro application in java.
Right now I have created one java dictionary DC.
and in that Dc i have created two database table .
Now I want to use this table in my web dynpro application.
Can anyone help me.

You can use the Dictionary Projects to create tables in Database. You must use codes to access these database tables that is created using Dictionary projects.
You have to use the DataSource in order to get connection ; Use Visual Administrator to see the data source name.
You can use the following code to access the database table.
ResultSet result = null;
try
     InitialContext initialcontext = new InitialContext();
     DataSource datasource = (DataSource)initialcontext.lookup("jdbc/<DataSourceName>");
        Connection connection = datasource.getConnection();
     Statement statement = connection.createStatement();
     result = statement.executeQuery( <Query>);
     connection.close();
} catch (NamingException e) {
     // TODO Auto-generated catch block
          e.printStackTrace();
} catch (SQLException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();

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

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!)?

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.
