Workflows in web dynpro java

Hi experts,
please guide me about the workflows in web dynpro java. i have to implement workflow outside SAP, i dont have any idea about it.

Dear Shilpi
For Configuring Workflows outside SAP we need to have a Gateway HUB where it channelizes to connect through Outside SAP. Based on the Tasks available in SWFVISU we can choose either Java or ABAP workflow where the Appropriate Task numbers will be available.
Check these links

Hope this Info will be helpful

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.

Logical Destinations in Web Dynpro Java

Hi!
Is it possible to access logical HTTP destinations maintained in SAP NetWeaver Administrator via Configuration Management -> Security ->Destinations in Web Dynpro Java source-code.
I would like to use such a destination to configure an URL target for a IWDFrame UI element.
Thank you very much in advance!
Regards,
Thomas

I found out that there is a [Destination Service API|http://help.sap.com/saphelp_nwce711/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm] for this purpose. Unfortunatly I am still not able to provide the required components security.class and tc/sec/destinations/interface to the web dynpro component. Maintaining them via Project Properties -> Web Dynpro is not allowed any more, and I couldn't find them in the DC perspective to add them as DC dependency.
Has anybody got an idea where these two libraries have gone?
Regards,
Thomas
PS: The 7.0 procedure, which can be found in various posts, doesn't seem to work any more for CE 711.

Date Column not getting sorted in a table in web Dynpro Java

Hi All,
I am facing an issue while sorting the date column in a table in my web dynpro java application.
When the date is displayed in the sql format in tha table, I am able to sort the date column successfully but when we convert the date field from sql format to util format in our table and then sort it does not work.
Kindly let us know the steps to be followed in this case to sort the date column of a table in Simple Date format as we do not want date in the sql format to be displayed.
Thanks & Regards,
Anurag

Hi,
You might want to check whether both your browser's language settings are identical. The browser language could also determine the date format.
As a workaround, you could add an extra attribute to your context, and set the calculated property to 'true'.
In your table, add a new column and bind to this new attribute, and hide your original date column
If you sort using the date column that's hidden now, you could use the calculated field to fixed-format your date the way you prefer (by using the SimpleDateFormatter class for instance)

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)

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
    I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
     procedure"
   Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
     signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

Piyush

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks
Arush

Hi,
Try this:
WDScopeUtil.put(WDScopeType.CLIENTSESSION_SCOPE, key, value)
WDScopeUtil.get(WDScopeType.CLIENTSESSION_SCOPE, key)
Ex:
WDScopeUtil.put(WDScopeType.CLIENTSESSION_SCOPE,"Key1","Value1");
String value1=WDScopeUtil.get(WDScopeType.CLIENTSESSION_SCOPE,"Key1").toString();

Web Dynpro Java - Light Portal Desktop

Hi Guys... I have a web dynpro java application that I want to display on a Light Portal Desktop, but when I display the iview... it gets cut. I mean I can see only part of my application and there is also a right scroll bar... It looks like the height size of the iview is set to "FIXED" but it's not. I Actually modifed all values for size even on the Light Framework Page used...to FULL_SCREEN. I don't know what's wrong. If I display the same iview using a Default Framework Page it looks fine... I'm using SAP EP 7.00 SP 16.
Is there any restriction for using Web Dynpro iviews for Light Porta Desktops?
Thank you.
David

David,
Webdynpro content is considered heavy and I dont think we can use it in LPD.
Update:
Note 916545 - Central Note for External-Facing Portal (NW 7.0)

" APPLICATION NOT FOUND" while deploying Web dynpro java Application

Hi, I am getting a message that "application not found " While deploying the web dynpro java application .......... please give me a solution for this .

Hi Ram,
This error comes generally when your webdynpro project does not have an application. To create an application in your webdynpro project follow the underlying steps:
<Project>->WebDynpro->Applications ---> right click and create New Application.
Follow the steps to create the application.
Now if you create archive and deploy, it will not give you the error again.

Reading contents of uploaded excel file in web dynpro java

Hi All.
I am aware how to provide facility to upload files in web dynpro java. But my requirement is that on uploading a particular file (for eg. an excel file having 10 columns), I need to read the contents of that file and store it in a table in R/3.Can anyone suggest a way how I can read the contents of the uploaded file?
Thanks and Regards,
Saurabh.

Hi.
I am having the following requirement : I have a FileUpload UI element where user clicks Browse button, selects a file from the local system and presses a Upload button. Upon pressing Upload, the name of the selected file and the contents of the file should be shown.
In the View context, I have two value attributes: FileName of type String and FileResource of type binary.
This is the code that I have in the Upload button action handler :
public void onActionUpload(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionUpload(ServerEvent)
    IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(
             IPrivateReadExcelView.IContextElement.FILE_RESOURCE);
    IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.
             getModifiableSimpleType();
    IPrivateReadExcelView.IContextElement element = wdContext.createContextElement();
    String fname = binaryType.getFileName();
    wdComponentAPI.getMessageManager().reportSuccess("File selected - "+fname); //Statement 1
     try {
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    // Statement 2
          InputStream in = new FileInputStream(fname);
          HSSFWorkbook wb = new HSSFWorkbook(in);
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    //Statement 3
          int sheetsNo = wb.getNumberOfSheets();
          for (int i=0;i<sheetsNo;i++) {
               HSSFSheet sheet = wb.getSheetAt(i);
               Iterator rowsNo = sheet.rowIterator();
               while(rowsNo.hasNext()) {
                    HSSFRow rows = (HSSFRow)rowsNo.next();
                    Iterator colsNo = rows.cellIterator();
                    while(colsNo.hasNext()) {
                         HSSFCell cell = (HSSFCell)colsNo.next();
                         wdComponentAPI.getMessageManager().reportSuccess("File uploaded" +
                              "successfully");
                         if(cell.getCellType()==1) {
                              wdComponentAPI.getMessageManager().reportSuccess("00000"+
                                   cell.getStringCellValue());
                         else if(cell.getCellType()==0) {
                              String str=""+cell.getNumericCellValue();
                              wdComponentAPI.getMessageManager().reportSuccess("11111"+str);
     catch(Exception e) { wdComponentAPI.getMessageManager().raisePendingException();
    //@@end
On pressing Upload button, name of selected file is being shown(Statement 1). I am also getting Statement 2 in the output. However I am not getting Statement 3 onwards.
Where am I going wrong? Can anyone shed some light on this?

Consuming External Web Services in Web Dynpro Java

Hi All,
I an trying to consume external web service in Web dynpro java using Adaptive Web Service Model.
But getting below mentioned error while executing the web service
Exception on execution of web service with WSDL URL 'D:\Web Service Project\CurrencyConvertor.asmx.xml' with operation 'ConversionRate' in interface 'CurrencyConvertorSoap'
Steps i followed are as below:
1. Created Adaptive Web Service Model for this i select WSDL source as "Local File System or URL"
In next step i select No logical destination radio button and click on next
In next step, browse the WSDL file and successfully import the WSDL file.
2. After successfully importing the WSDL file i wrote below code in Init method:
WebModel modelweb = new WebModel();
Request_ConversionRate reqConversion = new Request_ConversionRate(modelweb);
ConversionRate conversion= new ConversionRate(modelweb);
reqConversion.setConversionRate(conversion);
wdContext.nodeRequest_ConversionRate().bind(reqConversion);
3.After that execute the model - code is given below :
    IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
      wdContext.currentRequest_ConversionRateElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeConversionRateResponse().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Please let me know how to resolve this.
Thanks
Sandy

Hi,
You need to use destinations for metadata and modeldata.
Configure those destination in Visula admin.
you can refer to following link.

Hi,
Since the exception says "Are all referenced components deployed and available on the engine?"
Check wether any DC is used as a used DC in the webdynpro component which you are deploying.
If any used DC is available try to deploy that DC in the server and then deploy ur webdynpro application.
If all reference DC's are avialable in server, still if you get this error try to rename the component and reload+rebuild the project and deploy it.
Hope this helps you...

Web Dynpro Java : Failed to get deployable object part info for component

Currently we have a web dynpro java project which connects to the ABAP backend with Web Services. Everything seems fine, and when we transport to the production server via NWDI, we have the following error. Everytime we try to access the application , the error is occurred.
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to get deployable object part info for component com.sie.attachmentcomp.AttachmentComp
    at com.sap.tc.webdynpro.clientserver.cal.ClientComponent.getComponentDeploymentDescription(ClientComponent.java:784)

    at com.sap.tc.webdynpro.progmodel.components.ComponentUsage.createComponent(ComponentUsage.java:116)
It is working properly in our development , and testing environment. Only production has this error. And one weird thing is that this particular error occurred only sometimes to some user. For example; I could not access to the application with this error yesterday but my friend can access. Today, I can access in the morning but my friend cannot. For another friend , Yesterday he can access by using IE but not by Firefox. But today Firefox is fine but not with IE. It seems crazy.
For more information, in our J2EE engine for the production server, we have 3 server nodes (clusters). And we are not sure it is the source of the problem. Is there any solution , and any way to know from the application that we are on which server?
We also go and check from the Content Administrator in Web Dynpro Console. Under our project name, in the list of Components, sometimes we can see AttachmentComp but sometimes not.
Please help us as our project is about to go-live next week.
Thanks,
Yu
