  2. Select Tools, Folder Options.
    The Folder Options dialog opens.
  3. Select the File Types tab.
    A list of registered file types is displayed.
  4. Scroll down and select JNLP.
    The bottom portion of the dialog displays Details for the ‘JNLP’ extension.
  5. Verify that the details for the ‘JNLP’ extension box indicate the following information:
    • For Windows 2000/2003: The file opens with javaws.
    • For Windows XP: The file opens with Java Web Start Launcher.
    If JNLP files are not set as described, you can manually map the .jnlp extension to the javaws.exe application.
  6. Select Change in the Details for ‘JNLP’ extension box.
    The Open With dialog opens.
  7. Scroll down and select ‘javaws’ or ‘JavaTM Web Start Launcher’ and select OK.
