Mobile ADF: Webservice Call Using Oracle ADF Mobile Framework (Android)

Web-service Call Using Oracle ADF Mobile Framework (Android)

Writing web service 

I have written a simple webservice which will take String as parameter and return result in the form of String itself.

package samplewebservice; 

import javax.jws.WebMethod; 
import javax.jws.WebParam; 
import javax.jws.WebService; 

@WebService 
public class SampleService { 

    public SampleService() { 
     super(); 
    } 

    @WebMethod 
    public String sayHello(@WebParam(name="name") String name){
      return "Hello, "+name+" !!!!!!!!!!!!!!!!!!!"; 
    } 
 } 

Deploying Web-service 

Once service developed you have to deploy that service on some server. I am using weblogic server to deploy HelloService(You can select any server). Start your server.

• Select Application as Mobile Application(ADF) template

• Provide application name like WebServiceCall 

• Click on finished. it will create 2 project in application ApplicationController and ViewController

• Select ApplicationController and created webservice datacontrol.

• Provide WSDL with your system IP address because localhost and 127.0.0.1 doen't work for mobile. 

• Enter webservice url and datacontrol name

• Click on next then select method and click on finished.
• Now Select the ViewController Project and Right Click and go on new.

• Select ADF mobile from the Client Tire from category

• Provide the feature name like WebserviceCall and click on Ok button. It will created a folder with name of WebServiceCall inside public_html.
• An Entry with the feature name will added to adfm-feature.xml file
• Select the feature id from feature table
• Go to content tab
• Click on the + icon of file
• Select the taskflow it will ask you to enter name for task flow enter name and same taskflow will created.

• Now select the WebserviceCall feature folder and create amx page with name of LoginPage.amx
• Drag and drop that amx to taskflow as default activity
• Create responsePage.amx for showing service response

• Define the ControlFlow as ShowResult
• Expand created data control

• Drag and drop name from parameter to amx page as inputtext.
• Provide label as Enter your name
• Surround it with panelFormLayout

Retrieve af:table row data on enter without Java-Script

Retrieve af:table row data on enter without Java-Script

As we all know that Oracle ADF framework is tightly coupled with JavaScript and Ajax. Its never advisable to use you custom JavaScript. And its a common requirement to get selected row data on enter click.

Here in this sample I have invented a way to retrieve row data on enter key click in backing bean and display same on jspx page. Best thing of this sample application is that it reduce the overhead of making selected row as current row in ViewObject. 

This approach might have some limitation when you following any specific architecture but it suites best to retrieve selected row data on enter click without any JavaScript.
