Subject RE: commons-logging 1.1 in an applet
Date Thu, 07 Dec 2006 16:06:00 GMT
I don't have a solution but I can shed some light on the subject. Applets can not access the
following System Properties:

java.home		Java installation directory
java.class.path	Java classpath
user.name		User account name
user.home		User home directory
user.dir		User's current working directory

LogFactory.createFactoryStore() must be trying to access one of these.

Subject: commons-logging 1.1 in an applet

I have a program that can run as an applet or application.  When run
as an application, all logging works fine.  When I run the program as
an applet, I get an error.  Is there a way to fix this problem?

TIA.
Mark
