Or you can - pre-compile it using a pre-compiler called <literal>aopc</literal> such that - you won't need the XML file during load time. JBoss Aop provides a so-called - <literal>pointcut</literal> language where it consists of a regular - expression set to specify the interception points (or - <literal>jointpoint</literal> in aop parlance).
