Hi,
Thanks for the reply.
My scenario is that there is one web service and this web service has one method name "getQueryOutput".
Input parameter to this method is Select query
select ename form empthe return type of this method is Document. Currently I hard coded the select statement as I want to display all employee name as application starts.
But I am getting following error
Unable to read DataControl Usages, on loadDataControl for id: Genericwebfollowing is the code of method where I am calling Webservice data control
    public void Execute() {
        Trace.log(Utility.ApplicationLogger, Level.INFO, EmployeeList.class, "Execute",
                  "##############Inside Execute");
        List pnames = new ArrayList();
        List params = new ArrayList();
        List ptypes = new ArrayList();
        pnames.add("query");
        ptypes.add(String.class);
        params.add("select ename from emp");
        try {
            Trace.log(Utility.ApplicationLogger, Level.INFO, EmployeeList.class, "Execute",
                      ">>>>>> Before invokeDataControlMethod");
            // This calls the DC method and gives us the Return
            GenericType result =
                (GenericType)AdfmfJavaUtilities.invokeDataControlMethod("Genericweb", null, "getQueryOutput",
                                                                        pnames, params, ptypes);
            GenericType cfgt = (GenericType)result.getAttribute("Results");
            int count = cfgt.getAttributeCount();
            for (int i = 0; i < count; i++) {
                GenericType fgt = (GenericType)cfgt.getAttribute(i);
                Employee e = (Employee)GenericTypeBeanSerializationHelper.fromGenericType(Employee.class, fgt);
                GenericType tempgt = (GenericType)fgt.getAttribute("ENAME");
                e.setEname((String)tempgt.getAttribute(0));
                s_employees.add(e);
        } catch (AdfInvocationException e) {
            Trace.log(Utility.ApplicationLogger, Level.SEVERE, EmployeeList.class, "Execute",
                      ">>>>>> AdfInvocationException=" + e.getMessage());
            //AdfException ex = new AdfException("Error Invoking Web Service.  Please try later", AdfException.WARNING);
            AdfException ex = new AdfException(e.getMessage(), AdfException.WARNING);
            throw ex;
        } catch (Exception e2) {
            Trace.log(Utility.ApplicationLogger, Level.SEVERE, EmployeeList.class, "Execute",
                      ">>>>>> Exception=" + e2.getMessage());
            //AdfException ex = new AdfException("Error Invoking Web Service.  Please try later", AdfException.WARNING);
            AdfException ex = new AdfException(e2.getMessage(), AdfException.WARNING);
            throw ex;
    }Regards,
