Installer & java 1.4.2 bug (jre1.6 works)

Question

Hello,
I'm working with JWS and jre 1.4.2 and I need to use an "installer" to copy special files.
So, I tried to create an application JNLP using this JSP:
<%@ page contentType="application/x-java-jnlp-file" autoFlush="true"%>
<?xml version='1.0' encoding='UTF-8' ?>
<jnlp spec='1.0'
      codebase='http://localhost:9080/deployerWeb'
      href='application.jsp'>
  <information>
    <title>Application</title>
    <vendor>Company</vendor>
    <description kind='one-line'>
      Application
    </description>
  </information>
  <resources>
    <j2se version='1.4+' />
    <extension href='http://10.142.87.92:9080/deployerWeb/installer.jsp' />
    <jar href='application.jar' main='true' />
  </resources>
  <application-desc main-class='com.company.jws.Application' />
</jnlp>and an installer using this one:
<%@ page contentType="application/x-java-jnlp-file" autoFlush="true"%>
<?xml version='1.0' encoding='UTF-8' ?>
<jnlp spec='1.0'
      codebase='http://localhost:9080/deployerWeb'
      href='installer.jsp'>
  <information>
    <title>Installer</title>
    <vendor>Company</vendor>
    <description kind='one-line'>
      Installer
    </description>
  </information>
  <resources>
    <j2se version='1.4+' />
    <jar href='installer.jar' main='true' />
  </resources>
  <installer-desc main-class='com.company.jws.Installer' />
</jnlp>The installer does nothing:
package com.company.jws;
import javax.jnlp.ExtensionInstallerService;
import javax.jnlp.ServiceManager;
import javax.jnlp.UnavailableServiceException;
public class Installer {
     protected static void install() {
          try {
               ExtensionInstallerService installerService = (ExtensionInstallerService) ServiceManager
                         .lookup("javax.jnlp.ExtensionInstallerService");
               boolean installed = false;
               try {
                    //JOptionPane.showMessageDialog(null, "TODO: write common files");
                    installed = true;
               } finally {
                    if (installed) {
                         installerService.installSucceeded(false);
                    } else {
                         installerService.installFailed();
          } catch (UnavailableServiceException e) {
               //JOptionPane.showMessageDialog(null, "Install failed!");
     protected static void uninstall() {
          //JOptionPane.showMessageDialog(null, "TODO: delete common files");
     public static void main(String[] args) throws UnavailableServiceException {
          if (args[0].equals("install")) {
               install();
          } else {
               uninstall();
}When I launch the application JNLP, everything is downloaded correctly, but when JWS start the installer, the progress bar is blicking.
When I finally decide to cancel the installer, I have the following error:
JNLPException[category: Erreur dans le fichier de lancement ("Error in the launching file"): Exception: null : LaunchDesc:
<jnlp spec="1.0" codebase="http://10.142.87.92:9080/deployerWeb/" href="http://10.142.87.92:9080/deployerWeb/installer.jsp">

The same code and JNLPs are working fine with java 1.6...
Can someone help me please !!!

Hello all,
Sorry for the inconvenience, I finally found my problem...
It was a big mistake from me. The compiler was defined on java 1.5 for the installer project...
