I suspect you probably meant to ask that question in the JBoss AS 7 forum. Unfortunately you ahve posted it in the Byteman User forum which is doubly inappropriate because i) Byteman is not a part of AS7 and ii) your question has nothing to do with what Byteman provides.
Also, you probably ought to be aware that typing your question in a BIG typeface is seen by many people as equivalent to shouting. You are very unlikely to get a sympathetic response if you continue to do that.
logging-properties are used to configure logging during the initial boot phase (see boot.log).
For appclient directory see here, I would expect that this will answer your question.
As Andrew mentioned you should look into the forms how to write questions in a polite way
And just to add some information about the logging.properties file see the following documentation, https://docs.jboss.org/author/display/AS71/Logging+Configuration#LoggingConfiguration-Whyistherea%7B%7Blogging.properties%7D%7Dfile%3F.
