Setting Microsoft Windows Internet Explorer to use the required Java Web Start

Microsoft Internet Explorer uses the default file associations defined for the Microsoft Windows operating system to determine how to handle JNLP (Java™ Network Launch Protocol) files. By defining or modifying the default file application associated with processing JNLP files, you can redirect Internet Explorer to use the correct Java Web Start version. If you have multiple versions of Java installed, modifying this setting can prevent problems with opening the Visualizer.

About this task

This procedure directs Internet Explorer to use the Java Web Start version to open all Web applications. If you run other Web Start applications that require later versions of Java, use the direct launch approach instead.

Note: There are a couple of known issues with Java version 1.6 to keep in mind:
  • Java version 1.6 sometimes overrides the default Windows file association for JNLP files. If you use Java version 1.6 as your system JVM (Java Virtual Machine) and these steps do not allow you to successfully start and open the Visualizer, either try using another Web browser to launch the Visualizer, or use the direct launch approach instead.
  • If your workstation uses Java version 1.6, you may also need to configure the JRE (Java Runtime Environment) to accept automatic downloads. If your workstation has this issue, when you try to start the Visualizer, you will see an error message indicating that the application has requested a version of JRE that is not locally installed.
  1. From the Windows Control Panel, do one of the following steps:
    • From the Category View, double-click Performance and Maintenance. From the See Also navigation pane in the upper-left corner of the window, select File Types.
    • From the Classic View, double-click Folder Options.
  2. From the Folders Options dialog, click the File Types tab.
  3. Under the Extensions column, locate and select the JNLP entry. Entries are alphabetized by extension.
    Note: If the JNLP entry does not exist, click New to create the entry.
  4. Click Change.
  5. From the Open With dialog, make sure that Java WebStart Executable is selected. Click Browse to navigate to your installed Java directory.
  6. Select the executable file named javaws and click OK.
  7. Click OK to close the Folder Options dialog. (You can also close theControl Panel window.)
Results
Internet Explorer now uses the associated Java Web Start file to successfully process and open the Visualizer.
