Steps to use the WebService client in your Liferay portlet

1. Use the seperate tomcat instance to generate the stub classes from the
url
2. Create the portlet in your sdk
3. The lib folder of the portlet should have below jars
axis.jar
commons-discovery-0.2.jar
jaxrpc.jar
saaj.jar
wsdl4j-1.5.1.jar
4. Inside your portlet class we can write the logic to consume the service

package com.cignex;

import com.liferay.portal.kernel.log.Log;
import com.liferay.portal.kernel.log.LogFactoryUtil;
import com.liferay.portal.model.UserSoap;
import com.liferay.portal.service.http.UserServiceSoap;
import com.liferay.portal.service.http.UserServiceSoapServiceLocator;

import java.io.IOException;
import java.net.URL;

import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.PortletRequestDispatcher;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

UserServiceSoap soapUser = locatorUser.getPortal_UserService(new URL("http://test:test@127.0.0.1:8080/tunnel-web/secure/axis/Portal_UserService"));

//http://abc:abc@127.0.0.1:8080/tunnel-web/secure/axis/Portal_UserService
System.out.println("Calling from portlet");
if(null!=soapUser){
System.out.println("Inside soapUser not null*********");
UserSoap soapUserModel = soapUser.getUserById(10134);
System.out.println(" getEmailAddress:" + soapUserModel.getEmailAddress());

}

} catch (Exception e) {
e.printStackTrace();
}

}

String path, RenderRequest renderRequest,
