Hi

I am new to web service, There is a web service in .net created and that i have to call from java as aclient. I am able to call a web service without parameter, but when i am calling another web service by passing one parameter i am getting the below error. So please help me the to call a web service with parameter. As i am new to web service i have no idea how to call parameter with passing a parameter.

i am calling the web service as:
public void getSiteList() throws Exception
{
InFormODM odm = new InFormODM();
InFormODMSoap soap = odm.getInFormODMSoap();

com.phaseforward.informadapter.odm._1.Node node =new com.phaseforward.informadapter.odm._1.Node();
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.newDocument();

node.setAny("MK45632");
GetSiteListResult result = soap.getSiteList(node);

Assert.assertTrue( result != null );

Element root = (Element) result.getAny();
NodeList nodeList = root.getChildNodes();
for(int i=0; i<nodeList.getLength(); i++) {
Node serverAdapterNode = nodeList.item(i);

getLogger().info("Server " + i );
getLogger().info("\tID: " + serverAdapterNode.getAttributes().getNamedItem("ID").getTextContent());
getLogger().info("\tName: " + serverAdapterNode.getAttributes().getNamedItem("Name").getTextContent());
getLogger().info("\tUrl: " + serverAdapterNode.getAttributes().getNamedItem("Url").getTextContent());
}
}

Error getting when calling with one parameter

Normally any webservice is associated with a .wsdl file. A .NET webservice is no exception to this standard. Use the .wsdl associated with the webservice to generate a Java client and use the Java client to call the webservice.
