What JVM/OS versions are you using?
I am running JRE 1.5
I am running Redhat Linux ES 3
Thanks! 
The Asset Map has not been tested to run on v1.5 of the JVM. (There are some reports that it crashes). Your best bet is to use a 1.4 version of the JVM for matrix.
I uninstalled 1.5 and installed 1.4.2
Mozilla says it is installed when I check the about plug ins
However, when I load the admin window I get the puzzle piece that says the x-java-vm cannot be run without the plug-in
Any hints?
I just want to try out Matrix!
Thanks in advance <_<
what JVM did you install? We recommend using the blackdown version of the JVM when running matrix on linux.
there is a post here that might help

I got Blackhawlk loaded and the applet now works. Thanks for the help. Do you anticipate compatibility with the Sun JVM?
Hi,
I face a similar problem in accessing my application
I get the following exception:

also I get :

I face this problem in JRE 1.4 but not in JRE 1.5
Is this a issue specific to JRE1.4.?
do you have any bug raised in sun's bug data base for this issue…?
Please let me know.
Thanks in advance.
