Hi!
I am having a little difficulty getting the applet loader to work for my applet located at:
http://www.paulscode.com/demos/SoundSystem/09AUG2009/Helicopter.html (http://www.paulscode.com/demos/SoundSystem/09AUG2009/Helicopter.html)
It seems to be loading the applet fine most of the way, then it crashes. I get the following messages on the Java Console:
QuoteReading certificates from 11 http://www.paulscode.com/libs/lwjgl/JARs/lzma.jar | C:\Documents and Settings\Paul\Application Data\Sun\Java\Deployment\cache\6.0\9\386c6349-4ce47725.idx
Fatal error occured (5): null
I have used the applet loader before without problems. I have the require .htaccess file in the proper directory for lzma stuff. It contains:
AddType application/x-lzma .lzmaI have tried replacing all the jars and lzmas to make sure I'm using the most current versions. I have tried deleting my temporary internet files. I have tried changing the 'al_title' and 'al_version' arguments. I am doing nothing in my program to require a signature, and I am using all the lwjgl files in their original form (as contained in lwjgl_applet-2.1.0.zip from the Download section). The applet loads locally without a problem, but not from online.
I have also tried using only jars instead of lzmas. Then I just get the fatal error output:
QuoteFatal error occured (5): null
My HTML file looks like this (the lzma version):

</html>The only thing different about this applet from numerous others I've written in the past is the 'java_arguments' parameter. Do you think this might be causing the fatal error?
Any thoughts about what might else be causing the problem and what I can try doing to fix it?
Thanks in advance!

.htaccess changes should no longer be needed since lwjgl 2.1 and it should just work everywhere.
fatal error 5 means it is failing when it is trying to extract the jars.
it was a noted issue that the AppletLoader didn't throw enough information when it failed, this has been fixed in svn. If you try the latest nightly build of lwjgl from http://www.newdawnsoftware.com/hudson/ you should get a much better error in the console (instead of just null) and will help you more easily find the problem.
edit: p.s. on an unrelated note always the <param name="separate_jvm" value="true"> parameter in the applet tag when using lwjgl applets, it makes them work much better.
javalwjgl,
I uploaded the 2.2.0 nightly build files, removed the .htaccess file, added the 'separate_jvm' parameter, changed the 'al_version', and cleared the temporary internet files. The applet is loading fine now. Thanks for the fast and helpful response!
