problem deploying simple WS

I'm trying to create a simple Web Service and get a problem at deployment stage.

Firstly I create a simple Java class in the Java perspective.

public class HelloNige {
	
	public String hello (String name) {
		return "Hello " + name;
	}

}

I then go to the Web service perspective and right click on the project to create a Web service Deployment Descriptor.

I then right click on the project to build the EAR file.

I then try to deploy the EAR file which is when I get the following error:

4/09/2006 08:45:52 /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager)
 [Thread[Deploy Thread,5,main]] ERROR: 
[005]Deployment aborted 

Settings
SDM host : ausyd-8rvgc1s
SDM port : 50018
URL to deploy : file:/C:/DOCUME~1/smithnp/LOCALS~1/Temp/temp19039EasyTestWS.ear

Result
=> deployment aborted :

What am I doing wrong?

Thanks in advance,
