  • Is WebDynpro ABAP a viable option?

    Hi all
    Some generic questions, is WebDynpro ABAP a viable option? Can I suggest it to the customers? Is it a good practice to have UI and Business logic on the same server? Y are two strains of webdynpro one for ABAP and one for Java necessary?
    I have also heard ESS MSS runs on both ABAP and Java WebDynpro. Y is SAP complicating the skillset required to deal with Business Packages? Please give me links or direct answers as suitable. Thank you all.

    Hi Volker
    All that I have written is based on help.sap.com. And here is the link (Go to WDJ in Travel manangement and look at constraints).
    <a href="http://help.sap.com/erp2005_ehp_02/helpdata/en/46/51f0e994b85e40e10000000a11466f/frameset.htm">ECC 7.0 WDA</a>
    And yes you are right, ECC 6.00 is enhanced using EHPs -> enhancement package. I am talking abt EHP 2.
    I am using CAF on NW 7.0 and hence the concern. And when I say composite my UI is essentially calling faceless services. That alone gives me the power to orchestrate processes quickly. The only reason I put these questions is because the same are coming out of my customers too!! And I need to give a concrete answer on the UI paradigm as well. Though I have made up my mind the future releases of ESS MSS is troubling to hear. Thank you for the patience shown in answering my questions.

  • WebDynpro 4 Java & Persistence options : Any Idea how 2 read an XML?

    Hi,
    I was wondering if there is an easy way to store modified (or new) values in a WebDynpro application.
    e.g. A User adds a new row to an existing Table UI in Web Dynpro application with create button. I want to save this row either in an XML file, in a table connecting to database or in an ABAP table via RFC connection. Which option is a light (on resources?) and easy to implement. I think it's reading and writing to an XML file. What are the other options, if any?
    I've been trying to read an xml file (stored under src/mimes/Components/<com.sap.myComp>/test.xml as below:
    //controller code
    private static final String FILE_NAME = "test.xml";
    private static final WDWebResourceType FILE_EXT = WDWebResourceType.XML;
    IWDResource resource = WDWebResource.getWebResource(wdComponentAPI.getDeployableObjectPart(), EditView.FILE_EXT, EditView.FILE_NAME);
    wdContext.currentContextElement().setFile(resource);
    //end controller code
    //view Init() code
    IWDResource resource = wdContext.currentContextElement().getFile();
    File file = new File(resource.getResourceName().toString());
    /* I've also tried below
            FileInputStream fis = null;
         fis = new FileInputStream(file);
            url = file.getAbsolutePath();
            //url is null when printed?
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document doc = db.parse(file);
    doc.getDocumentElement().normalize();
    content = doc.getDocumentElement().getNodeName().toString();
    //end view Init() code
    When I print the value of content, I get it's initial value which is null. What is wrong?? any ideas?
    How to get the correct path to the stored xml and how to display its contents? I've read enough posts on SDN but couldn't get it working.
    Appreciate your help.

    hi,
    U r retriving the elements by tag name.So it just chks the tag name ie.<book> & gives u array of elements.But u need retrive d attribute of <book> tag itself.
    =Solution =====
    Add one more statement ----> var[]= doc.getElementsByName("book");
    Now u hav book elements as an array & can retrive id in for loop
    for(var; var.length;var++)
    doc.element[var].id.value

  • Start both Webdynpro JAVA and WebDynpro ABAP from UWL

    Hi all:
    We are facing a situation. We need to start both JAVA dynpro and ABAP dynpro applicaiton from uwl. The JAVA dynpro application is the ESS absense request. And we also developed other workflow which use ABAP dynpro as work item . The problem is when we regist our ECC system to UWL, the system can only provide  WAS java information or WAS ABAP. So there are alway one type of our work items can't start correctlly. How can I modify the UWL configuration to meet our requirement?
    Anyone knows please notify, thank you very much!
    Wayne

    Hi,
    when you try to register backend system , you will choose system alias which was already existing in the portal which has WAS hostname and port.
    that is sufficient. Based on visualzation parameters , you can launch webdynpro abap/java tasks.
    check below article

  • ALV Tree in WebDynpro ABAP

    Hi,
    In my present project we have requirement for developing ALV tree output using ALV configuration model in WD4A. Please provide sample code or tutorial related to ALV Tree development in WebDynpro ABAP.
    Best regards,
    Alleiah

    There is no hierarchy of nodes when building an ALV or Table Tree in WDA.  You still provide a flat structure of a single node.  What you do is specify certain columns to be hierarchy columns.  The framework then builds a sorting/grouping around these columns and turns them into the "pesudo nodes" of the tree. 
    This can be done via configuration or via coding:

    For instanace, taking the same flat SFLIGHT structure I can just define certain columns and create two different hierarchies:

  • Webdynpro ABAP called from IView JAVA works over http but doesn't over http

    Hello gurus, like I said in the subject, we have integrated inside our JAVA portal a WebDynpro ABAP and it's working good over http protocol (http://<servername>:<http_port>/irj/portal), but when you browse the portal over https protocol (https://<servername>:<https_port>/irj/portal), everything works fine exept the WebDynpro ABAP, is like if the javascript components didn't be loaded completly, because the buttons doesn't make anything, and only half of the table that is supossed to be loaded is showed.
    Do you know what kind of configuration I'm missing?
    Thanks and best regards

    You have to note here that for webdynpro ABAP applications, the http/https request is actually served by the backend server.
    So, while accessing your webdynpro ABAP application, the request will be like:
    https://<mybackendserver>:<backendport>/bc/sap/.....
    While creating a system object in your portal (System landscape), you will need to adjust the protocol to https and also set the appropriate https port of the backend server. Also, HTTPS/SSL communication should be enabled on your backend server.
    Please check the definition of your system object.
    You can find more information by turning on a HTTP trace and checking how the request is routed to the backend server upon accessing the WD4A application.
    Thanks,
    Shanti

  • IS Webdynpro for ABAP/JAVA is same?

    Hi Friends,
    I'm a SAP technical consultant. I would like to learn webdynpro for ABAP. Can anyone of you tell me webdynpro for ABAP and webdynpro for JAVA are same? with webdynpro for ABAP Can we acheive what we can do with webdynpro for JAVA?
    Thanks in advance,
    venkat.

    hi,
    Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
    The Web Dynpro model is based on the Model View Controller paradigm, and has the following features that build on the classic dynpro model:
    ·        Clear separation of business logic and display logic
    ·        Uniform metamodel for all types of user interfaces
    ·        Execution on a number of client platforms.
    ·        Extensive platform independence of interfaces
    Web Dynpro is available both in the Java and the ABAP development environment.

  • Implementing WebDynpro ABAP in JAVA Portal

    Hello
    We have a JAVA enterprise Portal and we would like to create an iView of WebDynpro ABAP application.
    We have done it in our QA portal by creating a system and in the property editor configuring the "Web AS Host Name" & "Web AS Path".
    It works great becuase there is only one ABAP application server.
    However, in Productoin we have several ABAP application server and one central instance.
    If i create a system using template and choose "SAP system with load balancing" , still In the property editor i see only  "Web AS Host Name" .
    How can i set in the system's property editor a group of servers that hold WebDynpro ABAP application ?
    Does anybody have a clue ?
    Adi J.

    Hi Adi,
    For load balancing purposes you should use the SAP Web Dispatcher. The Web Dispatcher will know all you web application servers and will redirect the requests to the app server with more resources available.
    Thus you can set the Web As hostname and port to the Web Dispatcher.
    You should avoid using the message server for load balancing purposes. I can suggest you the following SAP notes for further information:
    1225587 - WebDynpro ABAP with Loadbalancing in the Enterprise Portal
    1040325 - HTTP load balancing: Message Server or Web Dispatcher?
    945516 - Web Dynpro ABAP in a portal environment
    I hope this helps.

  • Personalization option for Standard Webdynpro ABAP iView

    Hello Experts,
    We are stuck with an issue on personalizing a Webdynpro ABAP application.  Personalization option is available for Webdynpro Java iViews, when we preview the iView from the Administrator's login and do a Control + Right click.  This will provide a dialog box where we can personalize the iView.  We can do personalization on the existing fields (hiding the fields, changing the text etc).  But this is not happening with Webdynpro ABAP iView. 
    Scenario:
    We have a Standard Webdynpro ABAP iView which has 3 rows of links (Row1 - 5 links, Row2 - 2 links and Row3 - 2 links).  The client wants only one link in Row1, one link in Row2 and one in Row3.  I tried hiding the other links through Personalization.  It is not working as am able to see the changes only with the Admin ID.  When I assign this iView to a different user and tried viewing the iView its showing all the links. 
    But the strange thing is that, if I hide the complete row (eg. Row2 both the links are hidden),  then am able to see the complete row being hidden with both the Admin ID and also the end user's ID.  So not sure where am I missing.
    Please refer the link for the Personalization option available for Webdynpro ABAP iView.

    Any help in this regard will be greatly appreciated.  Thanks in advance.
    Cheers

    Hi Volker,
       Thanks for your reply.
       I think, I have set the properties of the iView right. I have tried with all the options for the property "Launch in new window" property of the iView but it didn't work.
       "By home page framework" I mean that the link of the iView in portal has been created using the "Home page framework" i.e. from "SPRO" transaction in the backend.
       Please let me know if you need any other input from me.
    Regards

  • Displaying both ABAP webdynpro and Java Webdynpro tasks in the UWL

    Hi,
    We have two an issue when trying to get the UWL to process two different types of workflow tasks : ABAP webdynpro and Java webdynpro. 
    Examples of these tasks are:
    TS12300097 u2013 LeaveRequestApprover u2013 Java Webdynpro
    TS17900100 - ASR_PROCESS_EXECUTE u2013 ABAP webdynpro
    We have two backend systems configured
    SAP_ECC_Financials u2013 This has the WAS host pointing to the java stack (xxx:50000)
    SAP_ECC_Workflow u2013 This has the WAS host pointing to the ABAP stack (xxx.80xx)
    In transaction SWFVISU all the tasks which use Java webdynpro have been configured to use the u2018Javau2019system (SAP_ECC_Financials) using the SYSTEM_ALIAS parameter
    In the UWL configuration the system SAP_ECC_Workflow has been registered
    In addition to this all u2018Javau2019 tasks have had an extra UWl config XML created to ensure that the SYSTEM_ALIAS is set to SAP_ECC_Financials
    The system SAP_ECC_Workflow has been re-registered
    The UWL cache has been cleared
    However when we try to launch the java webdynpro tasks the system is trying to access the ABAP stack (It is still trying to access the Web AS location for the system SAP_ECC_Workflow even though the system alias was specified as SAP_ECC_Financials )
    The ABAP webdynpro tasks (in this case a HCM process and form) are launched correctly
    If we try the reverse (i.e  register the Java system SAP_ECC_Financials and change the SYSTEM_ALIAS parameter for the ABAP webdynpro tasks to system SAP_ECC_Workflow)  then the reverse happens.  The java tasks can be launched and the ABAP tasks cannot.
    Does anyone have a solution to this problem.  Surely other people have implemented both ABAP and Java webdynpro workflows?
    Any help much appreciated
    Andrew

    Thanks  a lot for all your replies..
    The workitem type registration has been done already, but still it doesn't work..
    But here is the actual problem...
    There is a link 'Execute Workitem' in the inbox of the approver, or the second level manager...
    In the leave application, when we click on this link it is taking to the portal as the task is the Webdynpro Java application task. Whereas, when using ABAP webdynpro application task, it is taking to R/3 - which means that the user cannot access this link without R/3 access. The users are given only portal access, they don't have access to backend R/3.
    The requirement is that the link has to take the user to portal directly instead of R/3 - i.e it should ask only for the portal id and password.
    Since it was working fine with leave application, I changed the task to Java webdynpro task, but I think the Java Webdynpro application is not deployed in the server.
    Please can anybody suggest.
    Best Regards,
    Sushmitha

  • OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

    Hi Experts
    We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.
    Rrgards,
    Srikanth.
    Edited by: Srikanth Kancherla on Apr 29, 2010 10:43 PM

    Hi Srikanth,
    as you seem to be already aware, the component is dynamically built.
    so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.
    What is it about this that you particularly want help with?
    Cheers,

    Hi,
    What do you mean by simple steps? You need to write little code to add select options in WDA. You can check this wiki for reference: Web Dynpro ABAP - Complex select-options component usages - Code Gallery - SCN Wiki
    And there are lot more documents available in SCN. search here

  • Default Values for Select-options In Webdynpro-ABAP

    Hi Freinds,
    Kindly,Help me in setting the Default values for the Select-options in Webdynpro ABAP.
    Here the Node and the Attributes are Created Dynamically, and then Displayed Select-options Component View.
    Regards,
    Xavier.P

    Xavier Reddy Penta sent me this question via email and I answered it directly yesterday. Here is the solution that I provided to him, so that it is stored with the original question:
    I believe your problem is that you are not setting the value into the range correctly.  You are setting it directly into the field symbol of the range like such:
    <FS> = L_STRING2.
    But ranges are deep objects. They have four fields: Sign, Option, High, and Low. This is from the online help:
    1.     sign of type c and length 1. The content of sign determines for every row whether the result of the condition formulated in the column is included or excluded in the entire resulting set for all rows. Evaluable values are "I" for include and "E" for exclude.
    2.     option of type c and length 2. option contains the selection option for the condition of the row in form of logical operators. Analyzable operators are "EQ", "NE", "GE", "GT", "LE", "LT", "CP" and "NP" if column high is initial, and "BT", "NB" if column high is not initial. With the options "CP" and "NP", the data type of the columns low and high must be of the data type c, and special rules apply for entries on the selection screen.
    3.     low of the data type defined after FOR. This column is designated for the comparison value or the lower interval limitation.
    4.     high of the data type defined after FOR. This column is designated for the upper interval limitation.
    So when you are moving the value into the field symbol you are setting it into the sign column.
    Here is an example of how you can access the components of the range:
    * create a range table that consists of this new data element
        lt_range_table =
          wd_this->lv_sel_handler->create_range_table(
               i_typename = l_typename ).
        IF l_fieldname = 'CARRID'.
          FIELD-SYMBOLS: <tab>         TYPE INDEX TABLE,
                             <struct>      TYPE ANY,
                             <wa>          TYPE ANY,
                             <option>      TYPE char2,
                             <sign>        TYPE char1,
                             <high>        TYPE ANY,
                             <low>         TYPE ANY,
                             <wa_values>   TYPE ANY.
          ASSIGN lt_range_table->* TO <tab>.
          APPEND INITIAL LINE TO <tab> ASSIGNING <wa>.
          ASSIGN COMPONENT 'OPTION' OF STRUCTURE <wa> TO <option>.
          ASSIGN COMPONENT 'HIGH' OF STRUCTURE <wa> TO <high>.
          ASSIGN COMPONENT 'LOW' OF STRUCTURE <wa> TO <low>.
          ASSIGN COMPONENT 'SIGN' OF STRUCTURE <wa> TO <sign>.
          <sign> = 'I'.
          <option> =  'EQ'.
          <low> = 'AA'.
        ENDIF.
