In some circumstances for example, to provide a clean environment in which to run Discoverer Plus, you might want to remove the Discoverer Plus applet from a
client machine. To remove the Discoverer Plus applet from a client machine, do the following:
a.
Display the JVM control panel for example, on a Windows machine, display the Control Panel, and double-click the Java icon.
b.
Click Settings in the General tab to display the Temporary Files Settings dialog.
c.
Click Delete Files. Alternatively, manually remove all files from the Sun Java Deployment Cache
directory. For example, on Windows, remove all files from the C:\Documents and Settings\Windows user name\Application
Data\Sun\Java\Deployment\Cache directory.
You might also have to clear the browser’s temporary files.
■
In some circumstances you might want to remove the Java run-time environment plug-in from a client machine. To do this, remove all versions of the Java 2
Runtime Environment SE from the client machine.
■
You can upgrade the Java Plug-in on a browser machine without affecting the certified Java Plug-in version installed with Discoverer. For example, when you
log in to Windows you might see a Sun Java Plug-in pop-up that informs you that a new version of the Java Plug-in is available for download. If you download and
install the new version, Discoverer continues to use the Java Plug-in version installed when you first started Discoverer on that machine.
