Thanks for the reply. I did go through that document and have a fair understanding of how the aspects are loaded.
My major concern here is, when I introduce a aop.xml (along other aop.xml present in the resource path) to the AspectJ load time weaver, what not should I do to modify the behavior of AspectJ that is essential for the application. I can come up with few: 1) Should not have aspects that should potentially exclude already defined application includes 2) Should not exclude packages that are needed bu that application by introducing explicit excludes in the aop.xml Regards, Rajaraman ---- On Fri, 03 Sep 2010 20:23:07 +0530 Andy Clement <[email protected]> wrote ---- AspectJ merges all visible aop.xml files it can 'see' from a particular classloader into one super-configuration. The rules that apply are: (from http://www.eclipse.org/aspectj/doc/next/devguide/ltw-configuration.html) ==== When several configuration files are visible from a given weaving class loader their contents are conceptually merged. The files are merged in the order they are found on the search path (with a regular getResourceAsStream lookup) according to the following rules: The set of available aspects is the set of all declared and defined aspects (aspect and concrete-aspect elements of the aspects section). - The set of aspects used for weaving is the subset of the available aspects that are matched by at least one include statement and are not matched by any exclude statements. If there are no include statements then all non-excluded aspects are included. - The set of types to be woven are those types matched by at least one weaver include element and not matched by any weaver exclude element. If there are no weaver include statements then all non-excluded types are included. - The weaver options are derived by taking the union of the options specified in each of the weaver options attribute specifications. Where an option takes a value e.g. -warn:none the most recently defined value will be used ==== For the weaving itself you have the option of reweaving or the new overweaving (see http://www.eclipse.org/aspectj/doc/released/README-169.html ).
