Issues with Java

Issues with Internet Explorer and Windows XP
If you are using Internet Explorer in a Windows XP environent, you need to download a Java Virtual Machine from Sun (http://java.sun.com/j2se/1.3/download.html), as Microsoft no longer supports downloading an "on demand" JVM.

Issues with JRE 1.4.
The Persona java clients do not work well with JRE 1.4, which is installed by default with Netscape Navigator 7. You must instead use JRE 1.3. To do this:

  1. Download JRE 1.3 from Sun's web site.
  2. Close all running instances of Netscape.
  3. Install it and select the "Netscape 6" option for the Java runtime to use for your browser.
  4. After the install is finished open the Windows control panel.
  5. Open the Java Plugin 1.4 control panel applet. On the Browser tab, uncheck Netscape 6.
  6. Open the Java Plugin 1.3 control panel applet. On the Browser tab, check "Netscape 6".
  7. Run Netscape. To verify that Netscape 7 is now using JRE 1.3, Select Tools > Web Development > Java Console. The console should report the current version as 1.3.x_n. The important thing is the first two digits are 1.3.

Netscape Navigator 4.0-4.05 cannot run JDK applet 1.1 client
Because of Netscape's incomplete JDK 1.1 implementation, Navigator versions prior to 4.06 don't support Persona's Java 1.1 applet. Navigator 4.0-4.05 users must use either the JDK 1.1 application client or the Windows Thin Client.

A connection could not be established to the specified Persona server
If while using a Java client you receive this error message, one possibility is that the Persona server certificate has expired. Contact your Persona Administrator for support.

java.io.FileNotFoundException errors
In Internet Explorer 4.01, multiple java.io.FileNotFoundException errors display in Java Console when starting a session. This is a known issue and there is nothing to worry about.

Unix systems
Unix system administrators should make sure that their systems are running at the latest patch levels required for Java support.

Keyboard limitations on Macintosh platform
The “-“ (minus) key on the alphanumeric keyboard does not send a “-“ to the screen. Rather, it sends whatever the minus key on the numeric keypad is mapped to. To avoid this, use the full popup terminal keyboard (Commands>View Terminal Keyboard).

In Mac OS 9, the function keys on the Macintosh keyboard are not available by default. To enable function keys in Mac OS 9:

  1. Click on the Apple icon, scroll down to Control Panel, and select Keyboard.
  2. Click on the Function Keys button at the bottom of the Keyboard applet.
  3. In the Hot Function Keys dialog, uncheck the checkbox that says "Use F1 through F15 as Hot Function Keys."
  4. After applying this setting change, Function Keys should be accessible within the Persona Java client.

Issues with the Remote Administration Tool client and the Local Java Applet
To run the Persona Remote Administration Tool client, you must not install the Local Java applet client. If you already have the Local Java Applet client installed, uninstall it and then delete the CLASSPATH= environment variable from the system environment variable table and reboot the computer. Contact your Persona Administrator for more information.
