Consuming Custom Webservices

Steps:

1. Create a new plugin (Ex: ConsumerPortlet-portlet)

2. copy following jar files into project lib folder

·         ProducerPortlet-portlet-client.jar file which is in  producer portlet/docroot/WEB-INF/client

·         axis.jar available at portal/lib/portal folder

·         commons-discovery.jar available at portal/lib/portal folder

·         jaxrpc.jar available at portal/lib/portal folder

·         wsdl4j.jar available at portal/lib/portal folder

3. Write following code in view.jsp

View.jsp

<%@page import="com.liferay.producer.model.ProducerSoap"%>

<%@page import="com.liferay.producer.service.http.ProducerServiceSoap"%>

<%@page import="com.liferay.producer.service.http.ProducerServiceSoapServiceLocator"%>

<%@page import="java.net.URL" %>

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

<portlet:defineObjects />

This is the <b>ConsumerPortlet</b> portlet.

<%

String remoteUser = "test";

ProducerServiceSoapServiceLocator locator = new ProducerServiceSoapServiceLocator();

ProducerServiceSoap soap=null;

try{

soap = locator.getPlugin_producer_ProducerService(_getURL(remoteUser, "Plugin_producer_ProducerService"));

}catch(Exception e){}

ProducerSoap foo = soap.getProducerWebservice(1);

System.out.println(foo);

System.out.println(foo.getPid());

System.out.println(foo.getCompanyId());

System.out.println(foo.getUserName());

%>

<%!

private URL _getURL(String remoteUser, String serviceName) throws Exception {

      // Unathenticated url

      String url = "http://localhost:7070/ProducerPortlet-portlet/axis/" + serviceName;

     

     

      // Authenticated url

      if (true) {

            String password = "test";

            url = "http://" + remoteUser + ":" + password + "@localhost:7070/ProducerPortlet-portlet/axis/" + serviceName;

      }

      System.out.println(url);

      return new URL(url);

}

%>

4. Deploy and run the application(Before deploying please enter data into Producer. Producer table with primarykey 1 because we are retrieving row with primary key 1)

Errors and Solutions:

1. Current URL /ProducerPortletportlet/axis/Plugin_producer_ProducerService generates exception: null

Solution: Please check the URL given in view.jsp is working or not by entering that url in web browser

2. No Producer exists with the primary key 1

Solution: Enter row into Producer table with primarykey 1 because we are retrieving row with primary key 1 using webservice

3. ClassNot FoundExceptions for org.apche.axis.Service, org.apche.axis.ServiceException, EntitySoapServiceLocator

Solution: Jar files are not copied to lib folder. Follow Step2.
