How to make Appmodule service interface

Exposing Appmodule's VO as a webservice is pretty easy in Oracle ADF. It can be achieved very quickly
Here are the steps:
  1.  Open the Appmodule and go to ServiceInterface link.
  2. Before creating the ServiceInterface you can also create your custom methods exposed to AM. These will be also converted to webservices.
  3. Now click on + icon in the ServiceInterface tab of AM.
  4. Custom methods exposed to AM will be displayed here as the Service
    Custom methods. Expose these if you want to.
  5. Now go to Service View Instances tab to expose your VOs to the webservices.
  6. Now you are ready to deploy this AM service interface to your server. Follow the deployment steps as follows:-
  7. Go to your model- >right click-> Deployment profiles->Business Components Service interface-> give a meaning full profile name.
  8. Now go to Application properties ->Deployment->Edit the ear-> Application Assembly->Model->Check only MiddleTier[Uncheck the common].
  9. Click Ok and deploy the ear to your server.
  10. Don't forget to add yourAppModuleNameService?wsdl after the model context-root

Useful methods in Oracle ADF. Part -1

1. Getting the VO

a.)  DCBindingContainer dcBindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
            DCIteratorBinding dcIterBind = (DCIteratorBinding)dcBindings.get("VO1Iterator");  //VO1Iterator define in page def
            ViewObject vo = dcIterBind.getViewObject();
b.) AppModuleImpl amImpl= getApplicationModuleImpl();

     ViewObject vo=  amImpl.getVO();

2. Getting the Application module
ApplicationModule am=vo.getApplicationModule();
        FacesContext fc = FacesContext.getCurrentInstance();
        ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
        BindingContext bc = (BindingContext)vb.getValue(fc);
        DCDataControl dc = bc.findDataControl("AppModuleDataControl");
        PublicPortalAppModuleImpl am = (PublicPortalAppModuleImpl)dc.getDataProvider();
3. Row count of a table
        RowSetIterator invoiceRsItr = dcIterBind.getRowSetIterator();
        System.out.println("invoiceRsItr.invoiceRsItr.getRowCount(): " +

4. Get URL parameter value
  public static String getURLParamVal(String pv_strParamerName) {
    HttpServletRequest objHttpServletRequest = (HttpServletRequest)getFacesContext().getExternalContext().getRequest();
    return objHttpServletRequest.getParameter(pv_strParamerName);

5. Get operationBinding e.g.- RollBack , Commit etc
      public static OperationBinding getOperBinding(String operationName)
      OperationBinding operBind=null;
      FacesContext fc = FacesContext.getCurrentInstance();
      ValueBinding vb = fc.getApplication().createValueBinding("#{bindings}");
      DCBindingContainer bindingContainer = (DCBindingContainer)vb.getValue(fc);
      oper = (OperationBinding)bindingContainer.getOperationBinding(operation);
      return operBind;

6. Get the selected rows for ADF table
      a.)  DCBindingContainer dcBindings =(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
        DCIteratorBinding dcIterBind =
        RowSetIterator invoiceRsItr = dcIterBind.getRowSetIterator();
        RowKeySet rwkset1 = tableBind.getSelectedRowKeys();
        Iterator iter=rwkset1.iterator();
        Row row=null;
        while (iter.hasNext()) {
            Key key=(Key)((List)iter.next()).get(0);
            System.out.println("key "+key);
            row =
            System.out.println("Email Selected-->" +

Note: HR schema's employee table is used, tableBind is the binding of the UI adf table
        Iterator iter = tableBind.getSelectedRowKeys().iterator();
        while (iter.hasNext()) {
            Object key= iter.next();
            FacesCtrlHierNodeBinding rw = (FacesCtrlHierNodeBinding)tableBind.getRowData();
            System.out.println("Invoice Selected-->" +

7. Selecting all rows of the table by a booleanCheckBox 

    public static void checkUncheckAll(String dcIteratorName, String rowName,
                                 String checkBoxVal) {
        DCBindingContainer dcBindings =
        DCIteratorBinding dcIterBind =
        RowSetIterator rsetIter = dcIterBind.getRowSetIterator();
        Row rw = null;
        boolean isFirst = true;
        while (rsetIter.hasNext()) {
            if (isFirst) {
                rw = rsetIter.first();
                isFirst = false;
            } else {
                rw = rsetIter.next();
            rw.setAttribute(rowName, checkBoxVal);
       // rsetIter.reset();    //reset to start the Iterator all over
        rsetIter.closeRowSetIterator();  //always remember to closeit-think it as resultset

Note:  dcIteratorName- name of VO iterator from Page Binding,VO column which has be implemented as checkBox,checkbox value-Boolean or Yes/No depending upon your logic
 8. Get the name of VOs exposed to the particular am
       String vonames[]= vo.getApplicationModule().getViewObjectNames();
        for (int i=0;i<vonames.length;i++){
