Axis2 (1.5) - Unable to see POJO deployed as service

[Sam Gehouse]

New to Axis2. Using the POJO guide for exposing service found in link:

http://ws.apache.org/axis2/1_5/pojoguide.html

I can see the wsdl in the browser, but cannot see the service. The service apparaently was not found. Any suggestion will be appreciated.

Following are the steps that I have taken.

  

Axis2Weather (it is web project containing WebContent)

package sample.pojo.data;

public class Weather {

package sample.pojo.service;

import sample.pojo.data.Weather;

public class WeatherService{

	 Weather weather;
	    
	    public void setWeather(Weather weather){
	        this.weather = weather;
	    }

	    public Weather getWeather(){
	        return this.weather;
	    }
}
 

The context root of the application is: Axis2Weather

Axis2Weather successfully gets deployed in the application server (WebSphere in this case) as an EAR file and the Axis2Weather application successfully gets started in the application server.

But when I enter the URL: http://localhost:9081/Axis2Weather/services , I get error as:

Any advice on why I cannot see the WeatherService (when the application is successfully deployed as EAR and app started successfully) will be appreciated.

I am familiar with Axis1 and have successfully deployed Axis1 service using "similar" approaches.
