Mozilla and multiple JREs

[noplasma]

Does Mozilla 1.4 support multiple JRE plugins? I need to support both the
1.3.1 and 1.4.1 version levels (to be called separately using EMBED flags).
If so, how do I configure that?

Also related, does Netscape 7 / Mozilla 1.0.1 support JRE 1.3.1? When I
link to the sparc/ns600/libjavaplugin_oji.so file, my applet fails to load,
while it works with the JRE 1.4.1 file.

Kind Regards,
Daniel

The MS Windows 32-bit JDK 1.4.2 JRE that I use allows you to select the JRE
you want to use from the Control Panel "Java Plugin" item. I'm not sure if
there is such a thing in any Unix like operating systems...

I also don't know if or how it is possible for each EMBED or OBJECT tag to
refer to a specific version of the JRE, since you can only have one Java
Plugin in a browser (but multiple JRE's on the system, of course), so you
may have to switch JRE/Plugin files between browser starts.

I believe it is virtually impossible to have your browser open a single
window with two Applets, each of which use a seperate (different version)
JRE VM.

Also related, does Netscape 7 / Mozilla 1.0.1 support JRE 1.3.1? When I
link to the sparc/ns600/libjavaplugin_oji.so file, my applet fails to load,
while it works with the JRE 1.4.1 file.
Have you looked into the Java Console, to see what errors you get when
loading the Applet ?
Or is the browser itself generating an error (the plugin cannot be loaded,
or somesuch) ?

You may be using a class or method that is new to JRE 1.4.2 and does not
run under older JREs.

Kind Regards,
Daniel

Hi,
Regarding the comment about Unix, yes, it's possible. The Java plugin
..so file is stored in the JRE directory, and the Mozilla plugins
directory contains a symlink to it. Just delete the symlink and make
a new one, pointing at whatever JRE's plugin you want to use.
