[Biojava-l] Applets

[Thomas Down]

Appologies for my last post on this topic something horrible
must have happened between my text editor and my MTA.  Hopefully
won't happen again.

Should be okay.  But you might want to try 1.4.0 anyway.

I really don't believe it's a security problem -- if the security
system were vetoing access to the file, I'd expect to see an 
exception.  Instead, getResouceAsStream() is returning null,
which specifically means that the named resource couldn't be
found.

How are you invoking the applet?  Could you send a copy of
the <applet> element from your document?

Thanks,

   Thomas.
