hi for all,
this a code of a class that i have created (WriteFile.java):

  | package com.sample.action;
  | 
  | import java.io.*;
  | import org.jbpm.graph.def.ActionHandler;
  | import org.jbpm.graph.exe.ExecutionContext;
  | 
  | 
  | public class WriteFile implements ActionHandler {
  | 
  |      
  |     private static final long serialVersionUID = 1L;
  | 
  |     public void execute(ExecutionContext executionContext) throws Exception {
  |                
  |        
  |         String message= null;
  |         executionContext.getContextInstance().setVariable("message", message);
  |         Object object=new Object();
  |         object=executionContext.getVariable("Priorite");
  | 
  |         // Stream to write file
  |         FileOutputStream fout;       
  | 
  |         try
  |         {
  |             // Open an output stream
  |             fout = new FileOutputStream ("C:\\wamp\\www\\uib-ged\\ref.txt");
  | 
  |             // Print a line of text
  |             new PrintStream(fout).println (object);
  |             
  |            
  |             // Close our output stream
  |             fout.close();       
  |         }
  |         // Catches any error conditions
  |         catch (IOException e)
  |         {
  |             System.err.println ("Unable to write to file");
  |             System.exit(-1);
  |         }
  |        
  |        
  |        
  |        
  |         }
  |                
  |       }
