Subject [logging] Commons logging in applets
Date Mon, 05 Jun 2006 21:59:27 GMT
I get a security error when some of my logging code is called from a 
method that was called by javascript. I have looked around at some of 
the forums but could not figure out a solution. All my jars are signed, 
and I even configured commons logging to only log to system.err and not 
the file system.

While this is kind of an applet issue, maybe someone here has 
encountered this before, basically the offending line is:
    at java.lang.ClassLoader.getParent(Unknown Source)
    at 
org.apache.commons.logging.impl.LogFactoryImpl.getLowestClassLoader(LogFactoryImpl.java:1250)

Thanks in advance, below is a lengthy trace, the exception lies at the 
bottom:
