[jboss-user] [JBoss Seam] - Re: NoSuchMethodException when acessing protected methods in

[pettersonfp]

Hello again,

I was having a problem in a machine with linux / jboss 4.2.0.GA and seam 2.0.
Now I am in home and the only difference is that I have windows xp.

Instead of NoSuchMethodException now I am getting another one.

Following are the code and the stack trace.

Disregard my previous message.

Thanks,
Petterson

Base.java

  | public class Base {
  | 
  | 	public final void execute() {
  | 		System.out.println("Base->execute");
  | 		doExecute(); // **** the error occurs here
  | 	}
  | 	
  | 	protected void doExecute() {
  | 		System.out.println("Base->doExecute");
  | 	}
  | 	
  | 
  | }
  | 

Derived.java

  | import org.jboss.seam.annotations.Name;
  | 
  | @Name("derived")
  | public class Derived extends Base {
  | 
  | 	@Override
  | 	protected void doExecute() {
  | 		System.out.println("Derived->doExecute");
  | 	}
  | 	
  | }
