ABAP RFC Validations in WebDynpro for Java

Hi All,
Any idea how I can handle ABAP validations in WebDynrpo for Java. For example, there is a standard BAPI for (MM01), howare the validations and ECC Configurations (as in plant data etc) shown in WDJ. Do they also come as some drop-down or search help etc?
Thanks,
Vamshi

Dear Vamshi,
In broad terms this is what you will need
1) you need to configure JCOs (that is if they are not configured already)
2) you need to implement the necessary MODELS for your WD for JAVA. These models will then be used to retrieve data to and from your RFC.
There's plenty information on SDN on how to implement a MODEL in WD for JAVA.
Here's a nice one to begin with:

How to passing lowercase values to RFC/BAPI using webdynpro for JAVA

Hi Exerts,
When we sending values to RFC/BAPI through webdynpro (JAVA), the values are sent in capital (uppercase) letters to ECC.
So if we fill xxxx, it is send like XXXX. Why? and how to avoid this?
Thanks in advance,
Joeri

Hi,
There could be two possibility if you are storing this value in ABAP table.
1. You are entering value in UPPERCASE in your webdynpro application.
2. The data stored in ABAP table, converts value in small to upper case.
1. Can you tell me how you are passing this value, is user entering value in some input field which is binded to some context and this value are you passing to RFC/BAPI...???
Or else before passing value to RFC/BAPI you can use toLowerCase string function and the npass this value to RFC/BAPI
e.g String name = wdContext().currentContextelement().getName().toLowercase();
Now pass this name to RFC/BAPI is should go as lowercase only..
This is from webdynpro java side..
2. If you are storing this value in ABAP table, check the domain/type of variable in ABAP table for which you are storing the value. Ask ABAPper, so that this value are stored in small case letter.
There is one tick in domain which you need to remove so that it stores in lower case. I dont have exact information but you can consult this with ABAPer.
Hope this information helps guy ..!!!!

Comparison between WebDynpro for ABAP vs. WebDynpro for Java ??

Hi,
Can someone tell me when should we go for WebDynpro for ABAP and when WebDynpro for Java. Is there any link where SAP recommends the one for the other.
Thanks in advance
Regards
Mukesh

Hi Mukesh,
Both are having its own strengths!! )
I think it all depends on your project requirement and the availabel resources.
If the developer is good in OOPs ABAP then he must go for Web Dynpro ABAP. But if anyone is good in JAVA then that person should go for Web Dynpro JAVA.
*In Short almost all Features supported in webdynpro ABAP are also Possible in webdynpro Java.
1] Webdynpro Java
Supports,
webservice
RFC Models
Accessing Portal information in Java
Easy sending E-mail
Strictly follows MVC architecture which seperate Business logic and Process flow.
Webdynpro Java is webbased programming model to develop SAP Applications.
Easy to learn
Easy to integrate in Enter prise portals.
Dynanamic Programming
*Easy access to R/3 Via RFC technology (Models)
2] Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
Hope this helps and solve your Problem
Cheers,
Darshna.

SAP uses Webdynpro to build portal content, which later will be configuted as an Iview in the enterprise portal. Webdynpro comes with Java and ABAP flavors. Both have in general the same functionality,the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
If you are good in ABAP go with ABAP Webdynpro, if you are good in JAVA, go with JAVA Webdynpro. But you will get good opportunities in JAVA Webdynpro compare to ABAP Webdynpro.
Thanks,
Chenna.

Problems between Xcelsius and WebDynpro for Java

How should I do to show Xcelsius in WebDynpro for Java?
How should I transport data between Xcelsius and WebDynpro?
How should I control WebDynpro with Xcelsius?For example,firing plugs in Xcelsius like in WebDynpro to change one view to another.
How should I do to execute a Java method in Xcelsius?For example,scheduling a job on clicking a button in Xcelsius.
Besides these,I also want to know the same problems between other BOE contents and WebDynpro for Java.
Regards,
Abe

Hi Pradeep:
Well that purely depends on the business application (project) your client is proposing. Following are very few factors which will drive for creating web-based applications:
VC: it's a UI modeling tool (non-programming) for creating rapid creation of web-based applications.
WD: its a powered by Java and ABAP with which you can create robust business applications.
If your client is very choosy about rapid application development, reporting, rich user interface, to reduce TCO then VC is the choice. Or if the project contains typical integration with SAP and non-SAP systems, complex business logic development, integration with WCM systems...etc then WDJ is the option.
If youve some sort of custom development with facilitating the Development Infrastructure (NWDI) then WDJ is the only option I could say.
We hope with NW CE 7.1.1(referred by Priyanka Singh) tighter integration between these TWO tools may over come the ambiguity of using them.
Tnx,
MS

PLEASE GIVE ME GOOD TIPS.

Hi Kishore,
Creating/Updating entries in tables through Bapis (RFC calls) work in the same way as it is done for other Bapis like those for returning values or even structures. All you have to do is
1. Import the model, create a model node in your context and bind it to the Input structure of the model under used models.
2.Create an istance of the Model input structure, like
     Z_Test1_Input input = new Z_Test1_Input();
3. Set attibutes directly under the input structure
     input.setAttr1("XYZ");
4. Set attributes under any other structure under Input Structure by first creating the instance of the sub-structure
    Z_SubStruct1 subStrc1 = new Z_SubStruct1();
    subStrc1.setSubAttr1("ABC");
5. Add all available instances of sub-structures to the instance of input structure
    input.set<SubStruct1>(suStrc1);
6. Add all available instances of tables under Input Structure after setting attributes within using
for (int iCount = 0; iCount < wdContext.nodeVn_ContactInfo().size(); iCount++) {
      Z_Table1 zTable1 = new Z_Table1();
      IPublic<YourComponent>.IVn_Table1Element tab1Ele = wdContext.nodeVn_Table1().getVn_Table1ElementAt(iCount);
      zTable1.set<TableAttr>(tab1Ele .getVa_Attr1());
      input.add<Table1>(zTable1);
7. Bind the instance of input structure to the model node.
   wdContext.nodeMn_TestModel().bind(input);
8. Execute the model object and then invalidate the output structure under model node (Put this code in try catch block)
   wdContext.currentMn_TestModelElement().modelObject().execute();
   wdContext.nodeMn_TestModel().nodeOutput().invalidate();
9. Retrieve values from the attributes, tables and structures under the Output Node of the Model Node (Mn_TestModel) as usual
and store wherever in context as required. In case of output tables, you need to use FOR loop to iterate through the tables and access elements within using index (using wdContext.node<YourRequiredNode>().get<YourRequiredNode>ElementAt(int index)).
Hope it is helpful.

Dear all,

how to access those employee using webdynpro for java for perticular employee number if i want 20016319
Send me the code for above requirement and where i have to wrirte that code exactly
Regards

Dear Kishore,
To get the Employee ID you have to create a Adaptive RFC Model (call BAPI) which will return you the employee pernr, for this
1. Create a model using : BAPI_EMPLOYEE_GETDATA
2. Get User ID using the code
public java.lang.String getUserID( )
    //@@begin getUserID()
     String userID = new String();
          try
                // getting Logged in userid
               IWDClientUser myUser = WDClientUser.getCurrentUser();
               userID = myUser.toString().substring(19).trim();
               StringTokenizer filterdUID = new StringTokenizer(userID,")");
               userID = filterdUID.nextToken();
          catch (WDUMException e)
               e.printStackTrace();
               return userID;
    //@@end
3. Execute the BAPI
public java.lang.String getEmployeeID( java.lang.String userID )
    //@@begin getEmployeeID()
     String employeeID = new String();
          Bapi_Employee_Getdata_Input employeeData = new Bapi_Employee_Getdata_Input();
          Bapi_Employee_Getdata_Output outData = new Bapi_Employee_Getdata_Output();
          Bapip0105B comm = new Bapip0105B();
          com.sap.aii.proxy.framework.core.AbstractList list = new Bapip0105B.Bapip0105B_List();
          list.add(comm);
          employeeData.setUserid(userID);
          Calendar cal = Calendar.getInstance(Locale.UK);
          Date date = new Date(cal.getTimeInMillis());
          employeeData.setDate(date);
          employeeData.setAuthority_Check("");
          employeeData.setCommunication(list);
          outData.addCommunication(comm);
          wdContext.nodeBapi_Employee_Getdata_Input().bind(employeeData);
          wdContext.nodeOutput_BAPI().bind(outData);
        try
               wdContext.nodeBapi_Employee_Getdata_Input().currentBapi_Employee_Getdata_InputElement().modelObject().execute();
               wdContext.nodeOutput_BAPI().invalidate();
        catch (WDDynamicRFCExecuteException e) {printMsg("Failed to Obtain Employee Data");
             e.printStackTrace();
        employeeID = wdContext.nodeBapi_Employee_Getdata_Input().nodeOutput_BAPI().nodeOrg_Assignment().currentOrg_AssignmentElement().getPerno();
        return employeeID;
    //@@end
Hope it Helps!!
Warm Regards
