When I try to use the registerMethod in my library I get an exception error but not in the pde.

The listings below demonstrate the problem.

In Eclipse I got the following exception:

Exception in thread "Animation Thread" java.lang.NoSuchMethodError: tests.PreTest.registerMethod(Ljava/lang/String;Ljava/lang/Object;)V
    at tests.PreTest.setup(PreTest.java:9)
    at processing.core.PApplet.handleDraw(Unknown Source)
    at processing.core.PApplet.run(Unknown Source)
    at java.lang.Thread.run(Thread.java:722)

I have tried using both 32bit and 64bit Procesing libraries.

Has you experienced the same problem? If so do you have a solution? Any ideas?

Thanks in advance!

Processing

1. void setup(){
2.   size(200,200);
3.   registerMethod("pre", this);
4. }
5. 
   
6. void pre(){
7.   println(millis() % 1000);
8. }
9. 
   
10. void draw(){
11. }

 
Eclipse

1. package tests;
2. 
   
3. import processing.core.PApplet;
4. 
   
5. public class PreTest extends PApplet {
6. 
   
7.     public void setup(){
8.         size(200,200);
9.         registerMethod("pre", this);
10.     }
11. 
    
12.     public void pre(){
13.         println(millis() % 1000);
14.     }
15. 
    
16.     public void draw(){
17.     }
18. }
