How to create REST service in Liferay

[Ziaul Chowdhury, geändert vor 13 Jahren.]

Hello Guys,

I am a newbie in Liferay.

Requirement:
I'm trying to consume web services of Liferay portal in iPhone by using REST services (XML and JSON).

Questions:

• I have seen in the link that Liferay provides opportunity to access the web services by using JSON. Is it possible to consume web services of Liferay in REST XML format?
  
• In parallel, I have generated WSDL file of Liferay web services by using Apache Axis 1.4. I want to create Java classes out of the WSDL file in order to make REST services. In order to do so, I have used WSDLToJava command of Axis. It creates Service, ServiceLocator, Stub and some other files. I want to use the procedure explained in the link. In order to do that, I have created a wrapper class which calls the methods from the services and the stubs and it is the @XmlRootElement of Axis. The code looks like the following:
  
  

  // RootService.java
  @XmlRootElement
  public class RootService{
    public String getByCity(String city) {
      String val = null;
      try{
        TestSoapService service = new TestSoapServiceLocator();
        TestServiceSoap port = service.getPortlet_Service();
        val = port.findByCity(city);
      }
      catch(Exception e){
        e.printStackTrace();
      }
      return val;
  }
  

  
  
  And the HelloService.java looks like the following:
  

  
  // HelloService.java
  @Path("/test")
  public class HelloService {
    @Path("cityWiseFind")
    @GET
    @Produces( { MediaType.TEXT_XML })
    public String getByCity() {
      RootService r1 = new RootService();
      String val = r1.getByCity("New York");
      return value;
    }
  }
  

  
  When I run this code, tomcat starts properly but I don't get anything in the browser in the REST URL. What could be the reason of that?

As a newbie, I'm not sure if it is the right way to convert SOAP services to REST service. Please correct me if there is any problem in the procedure which I followed.

Is there any other way to fulfill my requirement?

I'll appreciate any help. Thanks in advance.

Kind regards,

Ziaul
