Java integration with magento web services issue

Hi All,

I'm not able to fetch the right data from magento web service using java code, could you please help me out.

Here my java code is

//

Mage_Api_Model_Server_V2_HandlerPortTypeProxy proxy = new Mage_Api_Model_Server_V2_HandlerPortTypeProxy(
"http://twgc01a040/magento1/api/?wsdl");
String sessionId = proxy.login("magentobot", "123456");
System.out.println("Session: " + sessionId);
CatalogProductEntity[] products = proxy.catalogProductList(sessionId, new Filters(), "");
