Hi, I'm trying to test my applet locally, but it came up with SecurityAccesExceptions when trying to access a required config file. I've been told this is because applets are prevented from accessing files not on a server, for security etc. So I stuck everything onto my local server and gave an absolute path to the file (http://localhost/config.xml). That worked, but I have 2 queries:

1) The config.xml file then refers to another config file, in a field logconfigpath, which is accessed using new file(logconfigpath) in initialisation. Problem is, apparently the file constructer cant create a File from an absolute path like http://localhost/logconfig.xml. It says it cant find it... And if I set the logconfigpath to just be the relative path of the xml (logconfig.xml), it comes up with a security exception again... What to do?

2) How does the applet know if its being run from a server or locally? I stuck everything onto my local server and tried giving xml paths relatively, and it still didnt like it. I still needed to provide its absolute path on my localserver. Does this mean when this is eventually implemented on a proper server, I'd still need to provide the file locations absolutely?

Sorry if these are really basic questions...I'm quite the beginner...

Cheers,
