How to call legacy system screen in web dynpro for java?

Now I'm using Netweaver CE for building BPM (Business Process Management).
In BPM system, I wana call legacy system screen(ERP, C/S , Web, etc..) in web dynpro.
I'v already known how to call legacy system method and data.( using RMI, SOAP and RFC )
But I don't konw how to call legacy system screen.
If there is no way calling legacy system screen, I will have to build every screen using web dynpro.
It's so terrible.
So I think there is a way calling legacy system screen.
It's just my opinion.
If It can call legacy system screen in web dynpro, please let me know how to call it.
Or, If there is no way calling legacy system, how solve I this problem?
Thank you reading my question.

I assume that with "legacy system screen" you mean ABAP Dynp sceens. Of cause it would be attractive to integrate into new BPM processes. However there is a conceptional issue: You could easily integrate them e.g. into a WebDypro using a URL to to the so-called WebGUI (the ITS that makes Dynp screens Web enabled).
However the Dynp screen store all there state in the ABAP backend. This information is not available to to the process engine, e.g. to set the Task to completed or to use the data in Output Mapping.
In fact you need a way to wrap the how UI transaction into a WebDynpro screen including data flow.

Hi,
I don't think it can be done in WDJ.
Maybe something can be done on the portal end.

How to develop Web Dynpro for Java and run it locally

I want to learn Web Dynpro for Java but still struggling with the running it locally in my PC. What software do I need to install in my own PC in order to do that? I have NWDS in place and I can write the code and compile it already. Thanks!

Hi Anthony,
You need to have SAP Web Application server (SAP WAS) to run all the webdynpro applications. WAS can be installed either on your local system or on a server which can act as a central server.
You can download WAS from SDN, which is a trial version. Check this link.
http://www.sdn.sap.com/irj/scn/nw-downloads
For checking the minimul system requirments for installing WAS please check the PAM (Product Availability Matrix).
I hope this solves you issue. Please revert back in case you need any further information on this.
Thanks and Regards

Creating a purchase order in web dynpro for java.........

hello all,
i am new to web dynpro for java.i have already done an application
"Creating a Web Dynpro Application Accessing ABAP Functions" this application
have good document on sdn.
this application is working fine .
Now i got an requiremnt for creating a purchase order in web dynpro for java.
in normal report when i call the bapi the parameter are the header, headerx,item, itemx is an internal table.
CALL FUNCTION 'BAPI_PO_CREATE1'
EXPORTING
    POHEADER                     = HEADER
    POHEADERX                    = HEADERX
POADDRVENDOR                 =
TESTRUN                      =
IMPORTING
EXPPURCHASEORDER             =

i just want to know how can i fill these internal table in web dynpro
for java to create an application accessing "Bapi_po_create" .
Thanks

Hi Gopal,
I'm not sure what is your issue, it seems you're not really understanding how the Model structure works in WDP.
I'll assume few things here, like you know how to Import the Model into the WDP, and you know a little bit about what Java Classes will represent this Model in the Project.
Try these steps:
1. Import your Model into the Project;
2. Open your Component Modeler, create a Data Link between your Model / Component (Or Custom Controller, as you prefer)
- You can also use the "Apply Template -> Service Controler"
3. Map the Input of your Model as the Main Node, check the Input Tables (you prob. will have two, POITEM = ITEM - POITEMX = ITEMX)
4. Also, check the Return box, since this is BAPI return (You can use to display Backend messages)
Now you have the Model mapped into your Controller, you need to develop the Java function to execute it.
1. Create a new Input class, like
BAPI_PO_CREATE1_Input purchaseOrderCreateInput = new BAPI_PO_CREATE1_Input();
2. Bind your Input Node, in the Controller, with your Input Class;
wdContext.nodeBAPI_PO_CREATE1().bind(purchaseOrderCreateInput);
3. Set any Import parameters you need:
purchaseOrderCreateInput.setEXPPURCHASEORDER(XXXX);
4. To Add references to the Table, you will perform something like:
First, you need to know what "Structure" you need to add (POItem Structure) - You have a Java class that represents that Structure..
POITEM_Element poItemElement = new POITEM_Element();
poItemElement.setPROPERTY();   /// Set your Properties
purchaseOrderCreateInput.getPOITEM().add(poItemElement);
5. Execute your Input,
purchaseOrderCreateInput .execute();
Hope it helps,

Daniel

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.
regards,
Angelo

In Web DYnpro for java there is any Configuration controller?

Hi,
Experts,
I am having a confusion that is there any "Configuration Controller" present in Web dynpro for java.Where as i know that it is present in Web dynpro for abap could u please pass some idea on it.And how can identify the type of component in metadata files.
Thanks in advance,
Shabeer Ahmed.

Hi,
you have Configuration Controller that we can call it as CC in Webdynpro application which developed using FPM that is Floor Plan Manager, which is used as part of developing the ESS and MSS business package.
The configuration Component is used to difine all the View Navigations and Road Map steps and define prespectives, and Vac's, Events for navigation from one view to another view.
go through this link u came to know abt FPM

Catching errors in Web Dynpro for Java when thrown from RFC Raise Exception

Hello Developers,
I'm looking for information that explains how a Web Dynpro for Java application responds and processes errors that are thrown from a Raise Exception event within an RFC.
The Exceptions do not appear to be part of the Model and I can't identify how they get processed.
When rfc HRXSS_CAT_WD_RECORD raises exception PERNR_NOT_LOCKED this exception is passed back to the calling webdynpro CAT DC that displays the exception on the web page along with the log.
I would like to display a friendlier message and without the log. Any information on how to customize the handling of this error would be greatly appreciated.
Thank you,
Terry

Reg:Locking in Web Dynpro for JAVA.

Hi All,
When a user logged in the front end i am calling the lock function module(based on this locking mechanism is working) and when a user logged out i am calling the unlock function module(now the locked mechanism is getting unlocked).
now my problem is when a user closes the window abruptly without loging out,the unloeck mechanism should work at that particular instance.Please suggest me if this is possible or not in web dynpro for java.
Thanks,
Mahesh Nuli.

Hi,
I will give you two different solutions, use whatever you think fits best for you.
First One:
Whenever you call your "LOCK" function module, do not disconnect the ModelInstance. Create a Locking method in Java which returns a "com.sap.tc.webdynpro.modelimpl.dynamicrfc.DynamicRFCModelClassExecutable" instance. It should look like this:
InputClass inputInstance..
node.bind(inputInstance);
inputInstance.execute();
if fails, return null;
otherwise, return your inputInstance;
Keep this inputInstance into some Context Attribute. Whenever you wanna "Unlock", you can disconnect this input from the backend system.
InputClass inputInstance = wdContext.getInputInstance();
inputInstance.modelInstance().disconnectIfAlive();
This will work for all the cases you are currently having problem. However, this solution holds one connection.
Second One:
Assuming your transaction runs in one View, you can set this View lifecyle to "when_visible" - Doing that, whenever you navigate "away" from this View the method wdDoExit of that ViewController will be executed.
In this appoach, you dont need to store any "InputClass" - You can perform your Lock and disconnect from the backend. In your wdDoExit method you can code a "Disconnect If Connected" method.
Use whatever fits best.

Daniel

Invoke Workflow from Web Dynpro for Java Application

I am working on a custom web dynpro for java application and when the user clicks the submit button the SAP standard workflow (WS50000041) should be invoked. Does anyone have experience they can share with me on how to achieve this functionality? It should also be able to attach an adobe form or read data from the form and submit the data as xml.
Thanks,
Ashley

Hi Ashley,
Use following code in RFC to invoke your workflow -
DATA : w_subrc TYPE sy-subrc,
            w_wi_id LIKE swwwihead-wi_id.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
        EXPORTING
          task                      = ' WORKFLOW - WSxxxxxx '
          language                  = sy-langu
          do_commit                 = 'X'
        IMPORTING
          return_code               = w_subrc
          workitem_id               = w_wi_id
        TABLES
          input_container           = it_container
          message_lines             = lv_swr_messag
      COMMIT WORK.
With this code your workflow will get start. But u have to use workflow id in next application also in which your request is getting navigated. In that application you have to take this workflow ID and have to pass again in workflow using - PortalNavigation statements.
After that this workflow will get start to publish in your TaskList (My Task) in Portal. Remeber that your all task should be maintained in workflow table by using SWFVISU transaction.
After that go to Portal and Re-Register your UWL so that your new Workflow ID will get usable in portal.
With this way you would be able to use workflow with Web Dynpro Java using UWL and Workflow.

Can I Design a Forum with using web dynpro for java?

Hi All:
Can i design a forum with using web dynpro for java?
I want to design an application like a simple forum which maybe has many replies.So if i use
the UI technology "web dynpro for java", i will to create UI elements dynamically.How can i control this
dynamical UI elements to keep layout ?

Hi,
yes you can do that....
for exaple if you observe SDN...
you can imagine like....
A big Transparent Container(TC)....
Inside that number of other TCs(depending upon the question nd its replies...)....
In side each TC, again around 9 UIElements....
one for menioning what is the question/reply?
other for your description of question/reply...
other for your name,
displaing your fourm point... etc...
So it will be
for(loop till your (Question+No of replies))
Create Transparent Container....
Add Childs to the Container...
Decide your layout....
In case if you want to know how to create UIElements dynamically....
