Solution: Stack traces on actual devices

Question

I've created a tool to work around one of the major problems when developing for CLDC: getting proper stack traces. Using the tool you get stack traces (with correct line number info) on exception situations also when running MIDlets on real devices. You can redirect the trace to any desired destination (e.g. a log file).
There isn't much documentation yet but it works and it's a real time saver. Check it out at [http://jarrut.sourceforge.net].

I believe this does what you're talking about.
yourLoggerName.error("your error message",yourException);Since you are using log4j, check their documentation about the methods:
http://logging.apache.org/log4j/docs/api/index.html
While there, look up debug, info, warn, error, fatal, and if you are using a recent version of log4j also see trace. You'll want the methods that pass the message and Throwable.
