Hi,
I have the following code.
public class Test extends VelocityScreen
{
public void doBuildTemplate( RunData data, Context context )
throws Exception
{
Criteria criteria = new Criteria();
Vector custom = TestPeer.doSelect(criteria);
context.put("custom", custom);
// the context object has already been setup for you!
context.put ("hello", new String("Welcome To vTradEx"));
}
}
When I call Test.vm, I get the following error message. Any comment?
