Error while invoking the async service call

Hi All,

I have deployed a simple GWT(Google Web toolkit) test application(sample code generated in GWT project) in a Linux(Ubantu 10.4). When ever I enter the name and click on the Send button, I am getting error in the popup.

Server replies:

An error occurred while attempting to contact the server. Please check your network connection and try again.

In the error lgs on the server, I can see this

File does not exist: /var/lib/tomcat6/webapps/Test/test/greet

Can anyone give pointers on how to solve this problem. Following is the configuration web.xml

greetServlet

com.test.server.GreetingServiceImpl

greetServlet

/test/greet

Test.html
