Java Control Panel
Several operation will need to use the Java Control Panel. This is installed in the computer separately from the browser or any programs. Here is how to reach it:
- Click on the Start menu
- Select Settings
- Select Control Panel
- Select Java or Java Plug-in
- Go to the /Applications/Utilities/Java directory.
- Open the Java x.xx Plugin Settings application (x.xx is your plugin version).
- Run the Java Plug-In Control Panel executable:
- (JRE installation directory)/bin/ControlPanel
- or load the Control Panel applet page with a web browser:
- (JRE installation directory)/ControlPanel.html
Applets in web pages visited are cached by the browser into a Java cache space in local disk (different from the browser's cache). This allows a faster response when the same applet is used in another web page visited later.
However, on some occasions this may cause trouble. Namely, if you open a new web page that uses a different version of the Jmol applet, sometimes the browser will use the former applet version rather than the new one. In these cases, even closing and reopening the browser, or clearing the browser cache, may give no solution. Then, you will have to clear the Java cache manually.
- First, reach the Java Control Panel (see instructions above).
- Click on the Cache tab or menu section.
- Click on the Clear button (or Clear JAR Cache).
- Accept (OK / Yes).
Google Chrome browser
This web browser (released Sept. 2008) is only compatible with Java version 6u10 (also named 1.6.0_10), or later. If the browser is up-to-date, it should direct you to the adequate download page automatically whenever you try a page with an applet. If not, search Sun's Java site for this version (currently in beta, or Release Candidate state), or go to Java downloads full listing.
