Using the Java 2 Plug-in

Removing multiple Java 2 plug-ins from a client workstation

If you have more than one Java 2 plug-in installed on a client workstation then you may encounter problems running the Java 2 version of the Z and I Emulator for Web client.

Follow these steps to restore the client workstation to having only one version of the Java 2 plug-in:

1. Uninstall all the Java 2 plug-ins.
2. Install the Java 2 plug-in that you want to use to run the Z and I Emulator for Web client.

Clearing the Java 2 plug-in's cache

To clear the Java Plug-in's cache:

• Launch the Java Plug-in Control Panel. See Launching the Java 2 Plug-in Control Panel.
• Click the Cache tab at the top
• Click Clear JAR cache
• A message comes up saying that the cache has been cleared.

Determining whether the Java 1 or the Java 2 version of the Z and I Emulator for Web Client is running

To determine whether the Java 1 or the Java 2 version of the Z and I Emulator for Web client is running, follow these steps:

1. On the session panel click Help > About Z and I Emulator for Web.
2. On the last line of the about panel look at the version string.
   • If the version string ends with Java 2 then the Java 2 version of the Z and I Emulator for Web client is running. For example, 8.0.0-B20030326 Java 2
   • Otherwise the Java 1 version of the Z and I Emulator for Web client is running. For example, 8.0.0-B20030326
