Hi ,

I am new to velocity and i went through the journal on velocity at http://www.javaranch.com/journal/2004/03/Velocity-AnIntroduction.html.

I understood the article and tried to replicate the same example of Hello Velocity World but i am getting a strage exception like the one given below. I tried using HelloTest extending both VelocityServlet and VelocityViewServlet but both the times i got the same exception.

So kindly help me out in resolving the issue.

Exception ::
javax.servlet.ServletException: Class HelloTest is not a Servlet

Hi ,

I figured out the issue and solved the above said errors but got stuck up with another error.

let me post my HelloTest servlet java file,

public class HelloTest extends VelocityViewServlet {

public Template handleRequest( HttpServletRequest request,
HttpServletResponse response,
Context context ) {

Template template = null;

try {
context.put("name", "Velocity Test");
template = Velocity.getTemplate("hello.vm");
} catch( Exception e ) {
System.err.println("Exception caught: " + e.getMessage());
}

return template;
}
}

the error i get is ,
ResourceManager : unable to find resource 'hello.vm' in any resource loader
Exception caught: Unable to find resource 'hello.vm'
