  <p>and I don't understand why. I'm trying to get at several jars with my applet but this is the only one that's causing the problem (at least for the moment). I looked at <a href="https://stackoverflow.com/questions/7093935/java-webstart-attempt-to-sandboxed-jar-as-trusted-library">this similar question</a>, but since I don't have an extra library (unless the applet.class counts which I haven't signed anyway), this doesn't seem to apply here. I looked at <a href="http://docs.oracle.com/javase/6/docs/technotes/guides/jweb/mixed_code.html#manifest" rel="nofollow noreferrer">Mixing Signed and Unsigned Code</a>, but "Enable - show warning if needed" is clicked, "Trusted-Library: true" is in the MANAFEST file, and I'm running firefox 3.6.24 (as specific for a Linux machine which I have). I'd appreciated your help.</p>
