Programatically calling Web Service DataControl from App Module

Hey,
I've been following the 4GL ADF tutorial recently but have a question regarding initiating a web service call instead of using an entity object. The tutorial I am using is located at:
http://www.oracle.com/technology/products/adf/learnadf.html
On Page 102 - Adding Custom Methods to the Application Module there is a little piece of code to transfer some data from a transient view object into an entity object. The code is
public void createNewServiceRequestFromGlobals() {
ServiceRequestImpl sr =
(ServiceRequestImpl)getDBTransaction().createEntityInstance(ServiceReques
tImpl.getDefinitionObject(),null);
Row globalsRow = getGlobals().first();
sr.setProblemDescription((String)globalsRow.getAttribute("ProblemDescript
ion"));
sr.setProdId((Number)globalsRow.getAttribute("ProductId"));
getDBTransaction().commit();
What I would really like to be able to do is use a web service datacontrol instead of the entity object. Can anyone point me in the right direction?
Thanks,
Mark

I have the same problem
1. I have a data control what is a web service client to URL https:
2. JDev 11g build a model
3. I need to call this data control from java class
4. My java class simply must call a method of the web service, this method I see in the DAta Control, with the parameter and just return the String,
5. this is not a Web Application, is swing, I not have a Context
method in WS
public String ConsultaPlaca(String arg1);
How I can implement this?
Just in Java Class, not in page JSP. the java class is a library of other Java class, I need to build a file .jar

  • Calling web service request from PL/SQL

    I am trying to create Apex page with stock quote ticker - like what Yahoo has on their page. I have the right web service and have put together a page which works when you submit (created by the wizard). Instead of clicking submit to refresh the page I want to use Ajax to do this but for this purpose I need to know how to call web service from PL/SQL so I can do this in my on demand process. Any ideas?

    George,
    The documented way to call a web service using PL/SQL is to use UTL_DBWS package.
    Here are a couple of links that may be useful:
    http://www.oracle-base.com/articles/10g/utl_dbws10g.php
    http://www.oracle.com/technology/sample_code/tech/java/jsp/callout_users_guide.htm
    There is also an APEX package wwv_flow_web_services, but I couldn't find any documentation on it.

  • Trouble Calling Web Service Function From Runbook

    i have downloaded the OrchestratorServiceModule web services module from CodePlex and i am successfully using it in runbooks.  But for some reason when i call the runbook from another runbook, the Get-OrchestratorRunbook function returns no data
    ($runbook variable is $null).   The error message states the runbook name that i provide "is not found in Orchestrator".    This function works well when the runbook is called directly.   The variables
    are populated.  $creds is set to $null.   there are no errors regarding installing the module or finding the function.   any ideas as to why this would succeed when the runbook is called directly but fail when called by another runbook?
    $runbook = Get-OrchestratorRunbook -serviceurl $url -runbookpath $rbpath -credentials $creds

  • Web Service created from Function Module with output tables

    Hello,
    I created a web service from a custom function module.  This Function module has some export parameters and one table.
    The table parameter returns a list of data for selection.
    When I execute the function module, everything is returned fine.
    When I call the web service, the export parameters are returned but the table is empty.
    Has anyone encountered that kind of issue?
    Thanks!
    Laurent

    Please check the following few things while testing the WS:
    - Test the WS with WS Navigator (accessible from transaction WSADMIN or http://<server host>:<port>/wsnavigator/enterwsdl.html).
    - While doing the test, give the exact no. of digit if there is some input parameter (with 0 padding if necessary).
    - Make sure the "SKIP" check box against the table parameter is NOT checked.

  • Urgent - Error calling web service generated from plsql package

    Hi,
    I am using Jdeveloper 10.1.3 production release.
    I am trying to publish a plsql packaged procedure as a web service.
    My first question is -
    When I am publishing the plsql API as a WS, should I choose the style Document/Wrapped or RPC Literal? Document Wrapped is the default in the wizard.
    My second question - Depending on whether I choose Document/Wrapped or RPC Literal style, I get 2 different errors when I try to run the client java file (generated by Jdeveloper) that calls the web service. The client java compiles successfully but when I run I get these messages:

    Now all the classes are generated by JDeveloper automatically from the plsql API. So I am not sure why the errors occur and how to fix these.
    Also, these errors are occurring on plsql APIs that have input or output parameters of plsql record type or pslql table of record type. These errors don't occur if the api is simple with scalar input or output parameters only.
    I would appreciate any help on how to resolve these errors.
    Thanks,

    Hi,
    I'm wondering if the problem is actually that the client is failing to connect to the server correctly. Can I suggest that you switch on the HTTP Analyzer and see what comes back there.
    Is it possible it is a proxy problem? If you are working locally then I first suggest that you ensure that the Web Browser Proxy is off (see Tools -> Preferences -> Web Browser Proxy) - and that there are no exceptions listed (either with the proxy on or off) before you start the HTTP Analyzer.
    As to Doc/Wrapped or RPC. see this blog entry for a little more explanation:

  • Calling Web Services form Custom Apps (11.5.7) Forms 6i

    Hi,
    My basic goal is to invoke a .net web service from a custom form. The web service is used to make a charge to a creditcard. I am currently using kind of convoluted method to achieve this. Below are the sequence of steps I do to achieve this
    1) I make a call to concurrent prog (host prog) and wait on the concurrent program to finish.
    2) From the concurrent prog's shell script I run the Java prog
    3) The Java prog invokes the web service and upon successful completion inserts a record into database
    4) In the form I check for the newly inserted record after the concurrent prog completes and treat it as a successful transaction.
    The limitations I have is Oracle 8i database, Forms 6i and EBS 11.5.7. Additionally I need to wait on the web service to complete successfully before I display a message to the user, this was the reason I was using a concurrent prog.
    Any suggestions/ideas to cut short the process is appreciated.
    Thanks,
    Srikanth

    This may seem a bit silly but could you install a 10g/11g database somewhere and then create a plsql package/function on the new rdbms to call the webservice? Then access the function via a dblink? I haven't done it with webservices but we do access plsql programs over dblinks all the time (we usually do keep them at the same rdbms version though).

  • Web Service (SOAP) From Oracle Forms

    From the exaples of calling web services (soap) from pl/sql, it seems very poor and troublesome. I've seen a few articles with good points about why not to do this from pl/sql. So, I was hoping someone in the forums could share their opinions and approaches to using web services from forms based applications. I would ideally like to hear reasons people chose not to use pl/sql.

    There are some examples of calling web services from forms on the Forms OTN page - works fine although I would encourage the use of the new JVM pooling features as this will aid scalability and performance.

  • Error calling web service from Adobe form

    Hi Experts,
    While calling web service form my adobe form, i was getting an error as below saying "Error attempting to read from the file" followed by the URL of my web service.
    To create the above scenario i followed the following steps:
    1. Create a Function module and create a web service from that function module.
    2. Through SOAMANAGER, download the WSDL file for the generated web service.
    3. Create an Adobe form with an empty Interface and create a new Data Connection on the form using the downloaded WSDL.
    4. Generate this adobe form using an ABAP report.
    Kindly extend help on this to figure out if I'm missing something!!!

    Well questions related to Web Services have been answered here in past, please Search on SCN for links to it.

    Yes, SAPHTTPA (runs on application server) and/or SAPHTTP (runs on front-end pc), one of which, is required for HTTP communication.  So far, nothing too elaborate as far as SOAP goes, but the logic is simplistic.  Here's some sample code:
      DEST = 'SAPHTTPA'.
      TRANSLATE HOST TO LOWER CASE.
      MYURL = 'wssrvTest/Service.asmx/GetByOrderItem'.

  • How do i call web services from SAP ABAP

    Hello,
    Ian working with .net team. they are using sap .net Connector to connect SAP. But my job is In SAP side when Purchase Requisition is created, I have to call web services from ABAP and i have to pass the Purchase Requisition number to web service(.net Program). Please help me how to call web services from ABAP and how to pass value. Any one help me with example.
    Thanks
    RaviKumar

    Hi Ravi,
    If you can call EJB from ABAP and from EJB call Web service which you want to call. I am giving code to write in EJB business method processFunction.
    public void processFunction(Function function) {
       IRepository repository;
       repository = new Repository("TestRepository");
       JCO.MetaData fmeta = new JCO.MetaData("ZTEST_EJB");
       fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0,  0,  
       JCO.IMPORT_PARAMETER, null);
       fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0,  0,
       JCO.EXPORT_PARAMETER, null);
       fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0,  0,
       JCO.EXPORT_PARAMETER, null);
       repository.addFunctionInterfaceToCache(fmeta);
       JCO.ParameterList input  =
       function.getImportParameterList();
       JCO.ParameterList output =
       function.getExportParameterList();          
       JCO.ParameterList tables =
       function.getTableParameterList();
      if (function.getName().equals("ZTEST_EJB")) {
                        output.setValue(input.getCharArray("REQUTEXT"),"ECHOTEXT");
    output.setValue("This is a response " + table.getString("E_NAME") +" " + output.getName(1), "RESPTEXT");
      else if (function.getName().equals("STFC_STRUCTURE")) {
      JCO.Structure sin  = input.getStructure("IMPORTSTRUCT");
      JCO.Structure sout = (JCO.Structure)sin.clone();
      try {
          System.out.println(sin);
       catch (Exception ex) {
           System.out.println(ex);
                        output.setValue(sout,"ECHOSTRUCT");
    output.setValue("This is a response from Example5.java","RESPTEXT");
    }//if
    Here REQUTEXT, ECHOTEXT are import parameter and RESPTEXT is the Export parameter of Function module ZTEST_EJB in SAP.
    Here from this bisuness method you can call web service which you want and give back the result of webservice to ABAP F.M.

  • Calling web service from oracle forms 10g

    Problem Description:
    I'm following the steps as per the doc:
    http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
    to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
    WSDL for external web service used is http://gend:83/DesignService.svc?wsdl
    The service was developed by us.
    Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
    The code from oracle form to call web service is as below:
    DECLARE
    jo ora_java.jobject;
    xo ora_java.jobject;
    rv varchar2(2000);
    ex ora_java.jobject;
    str varchar2(100);
    BEGIN
    jo := GendServiceClient.new;
    rv := GendServiceClient.sendHello('Nora');
    EXCEPTION
    WHEN ORA_JAVA.JAVA_ERROR then
    message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
    WHEN ORA_JAVA.EXCEPTION_THROWN then
    ex := ORA_JAVA.LAST_EXCEPTION;
    message(Exception_.toString(ex));
    END;
    Any help/ideas on this is greatly appreciated. Thanks.

    My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
    I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.
    Thanks

  • Calling web service from oracle forms fails with ORA_JAVA.JAVA_ERROR

    The code from oracle form to call web service is as below:

    Yes, it is the message line - so basically this call fails => rv:= CurrencyConvertorStub.ConversionRate(jo,'CAD','USD'); and control goes in the exception block
    WHEN ORA_JAVA.JAVA_ERROR then
    message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
    Below is the code from java stub that was generated using JDeveloper by using web services stub/skeleton and associating the WSDL

    Envelope requestEnv = new Envelope();
    Body requestBody = new Body();

    String wrappingName = "ConversionRate";
    String targetNamespace = "http://www.webserviceX.NET/";
    Vector requestData = new Vector();
    requestData.add(new Object[] {"FromCurrency", FromCurrency});
    requestData.add(new Object[] {"ToCurrency", ToCurrency});
    requestBodyEntries.addElement(toElement(wrappingName, targetNamespace, requestData));
    requestBody.setBodyEntries(requestBodyEntries);
    requestEnv.setBody(requestBody);

  • Is there a way to call web service from 2 servers??

    Hi,
    I need to know if its possible to call web service from 2 different servers without having load balancer??? I mean, if one of the server has heavy work on, then it should call web service from the other server.
    Thanks in advance.
    Best Regards.

    Hi,
    WebLogic Cluster has this feature ( Load Balancing & Failover ). If you will deploy your WebService to a WebLogic Cluster and then If you will put a Proxy in front of it like (Apache)...Then it is Possible.
    <h3><font color=maroon>What All You Need To Do ? ...... as following</font></h3>
    <b><font color=maroon>Step1).</font></b> Create a WebLogic Cluster (minimum two ManagedServers)
    http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
    <b><font color=maroon>Step2).</font></b> Install a Proxy like Apache in frot of them like following:
    http://weblogic-wonders.com/weblogic/2010/05/13/apache-proxy-as-static-content-repository/
    Or
    http://weblogic-wonders.com/weblogic/2010/08/01/weblogic-httpclusterservlet-proxyserver/
    <b><font color=maroon>Step3).</font></b> Now Configure a FrontEnd Host for your Cluster by providing the ProxyServer Host name as the FrontEnd of your Cluster. This step is required to Generate the Dynamic WSDL with the Address of the Frontend.(Not of a perticular WebLogic Server)
    http://weblogic-wonders.com/weblogic/2010/06/21/configuring-frontend-host-and-port/
    <b><font color=maroon>Step4).</font></b> Deploy your WebService on the Cluster
    <b><font color=maroon>Step5).</font></b> Now Hit the WebService using the Proxy URL:
    Example:
    http://ProxyHostname:proxyPort/ServiceContextRoot/ServiceURI?WSDL
    Thanks
