Thanks - I checked the slf4j-ext project when I started, but not the Subversion repository. I presume this is a post-compile step rather than runtime byte code alteration?
No, the Agent extensions perform byte code engineering at runtime. BTW, the subject of this thread is "Least-effort logging with *bytecode* modification".
Out of curiousity (not criticising!) what was the reason for picking javassist rather than aspectj?
I think the goal was to add logging at runtime. Can you do byte code engineering with AspectJ? I'll let Thorbjørn give a more authoritative answer. It looks like you have already done some work using AspectJ-generateed logging. How useful do you find the results, mildly useful, useful, or very useful? -- Ceki Gülcü Logback: The reliable, generic, fast and flexible logging framework for Java. http://logback.qos.ch
