1. take some time to format your question. 2. if there are several errors to solve, post them in separated questions. 3. start to respect the people that will read you and stop using sms style. — Pascal Thivent, Oct 18 '09 at 19:45

My first thought was that your log4j XML or properties file wasn't picked up when log4j initialized. Make sure one of them is in your CLASSPATH.

A more careful reading of your exception suggests that you're trying to use a port that a Windows app already has taken control of.

Do a "netstat -a" to see what ports are currently in use and what's attached to them. Pick another one for your log4j appender to use.

Have you written a custom appender to write log messages to SMS? Something else is using the port you've chosen.

EDIT:

The jre/lib directory is not in the CLASSPATH. You should not be putting any of your code in that directory. It should end up in the directory where your compiled .class files are written to.

@duffymo: the port in question is a serial port. Note the javax.comm package. – erickson Oct 18 '09 at 19:10
