If you are having problems loading the Java asset map follow these steps to diagnose the problem.
If your Java asset map fails to load:
Make sure that you that you have the latest version of the Java Runtime Environment, which at the time of writing is 1.4.2-03.
If you are behind a firewall, make sure that it is not blocking applet tags.
Make sure that you are not running two versions of the JRE. If you are using Internet Explorer on windows, make sure that the
Sun JRE is used instead of the Microsoft JRE.
If the applet fails to load, check the Java Console for the cause of the error. Any error mensioning 'bad magic number' is
almost always due to a version of the JRE which is less that 1.4.
If the Java asset map does not seem to function properly:
Make sure that you have the latest version of your browser. The currently supported browsers are:
Internet Explorer 6.0 and above
Mozilla 1.4 and above
Firefox 0.8 and above
It is possible that other browsers will work with Matrix and the asset map. Basically, make sure that your
browser supports Live Connect and Java >= 1.4
Symtoms of browsers that do not support Live connect are:
popups are not opened when creating new links
The asset map does not refresh when assets are updated.
Java Asset Map on Linux
Several people have noted that the asset map does not work with version 1.4.2_04-b05 of the Java Virtual Machine on gecko based browsers (mozilla, firefox, etc) on Linux. The asset map fails to load when using this version of the JVM (and possibly other versions by Sun) on linux. A solution to this is to use the blackdown version of the JVM instead.
I'm assuming the differences between Java 1.4.2-03 and 1.4.2_04-b05 is the issue here?
Anyone else been able to get this JVM to load the applet?
Here's the output from the java console if it helps;

We are using the blackdown version 1.4.2-rc1 on mozilla firefox (gentoo linux) here without any problems. You might want to try this version, because i vaugly remember using 1.4.2_04-b05 without success.
I've got a quirk with the Asset Map not loading under Internet Explorer. The set ups are: IE 7 & Java 6 Update 19, and IE 8 & Java 6 Update 20. It works under FF, Chrome & Iron on the same machine as IE8 & Java 6U20.
The error that we get when loading is:
Java Plug-in 1.6.0_20
Using JRE version 1.6.0_20-b02 Java HotSpot™ Client VM
User home directory = C:\Documents and Settings\oleej
load: class net/squiz/matrix/assetmap/AssetMap.class not found.
