Function call trap of Java codes with the help of AspectJ and XML

It is shown how the new technologies, AspectJ and XML, can be used for maintenance and development of Java applications. The presented all-purpose software solution gets usable runtime function call information from almost any Java application using the aspect oriented Java extension AspectJ and writes into a simply browsable directory-like structure in XML format without modifying original Java source code. Original Java code and AspectJ code will be compiled using the AspectJ compiler into standard Java byte code format. Finally it is shown how efficiently this new solution is and what experiences we had in compiling with and using this tool.
