ADF Mobile - Programmatically call RestServiceAdapter for POST Request

In my previous blog entry we saw how to get Rest WebService based form values in managed bean programmatically. In this entry will see how RestServiceAdapter interface lets you trigger execution of web service operations without the need to create a web service data control or interact with it directly.

Below code will explain how to get REST WebService based form values in managed bean and programmatically call the RestServiceAdapter for the POST request . Already there is a documentation on this, but here I'm trying to explain the end to end scenario as mentioned in below steps.
  1. Get the form values from departmentsIterator programmatically. 
  2. Dynamically construct the response xml based on departmentsIterator.
  3. Set the Rest WebService Connection with POST request option.
Take an example with mobile application having two screen. First screen consists of departments list and in second screen you can add new department for the Save button I have created the managed bean with actionListener method as below. 
public class DeptBean {
    public DeptBean() {

    public void addDeptAction(ActionEvent actionEvent) {
        RestServiceAdapter restServiceAdapter = Model.createRestServiceAdapter();
        // Clear any previously set request properties, if any
        // Set the connection name
        // Specify the type of request
        restServiceAdapter.addRequestProperty("Content-Type", "application/xml");
        restServiceAdapter.addRequestProperty("Accept", "application/xml; charset=UTF-8");
        // Specify the number of retries
        // Set the URI which is defined after the endpoint in the connections.xml.
        // The request is the endpoint + the URI being set

        ValueExpression ve =
        Object obj = ve.getValue(AdfmfJavaUtilities.getAdfELContext());
        if (obj instanceof VirtualJavaBeanObject) {
            try {
                VirtualJavaBeanObject vjbo = (VirtualJavaBeanObject)obj;
                String postData = this.constructXMlResponse(vjbo);
                response = restServiceAdapter.send(postData);
            } catch (Exception e) {

     * Construct the XMLResponse based on the VirtualJavaBeanObject dynamically
     * @param vjbo
     * @return
    public static String constructXMlResponse(VirtualJavaBeanObject vjbo) {
        String XMLResponse = "";
        if (vjbo.getAttributeInfoCount() > 0) {
            String xmlRootTag = getClassName(vjbo.getName());
            XMLResponse += "<" + xmlRootTag + ">";
            int count = vjbo.getAttributeInfoCount();
            for (int i = 0; i < count; i++) {
                AttributeInfo fieldName = vjbo.getAttributeInfo(i);
                XMLResponse +=
                        "<" + + ">" + vjbo.getAttribute( + "</" + +
            XMLResponse += "</" + xmlRootTag + ">";
        return XMLResponse;

     * Get the class name with/without the package
     * @param className
     * @return
    public static String getClassName(String className) {
        int firstChar = className.lastIndexOf('_') + 1;
        if (firstChar > 0) {
            className = className.substring(firstChar);
        return className.toLowerCase();
Note:- The GenericType is only exposed in SOAP data controls, so Rest Webservice data control can't be executed directly using AdfmfJavaUtilities.invokeDataControlMethod.
