This is interesting. You may also be interested in AspectJ (www.aspectj.org). For more context on "aspects" (which sound similar to what Michael is calling "services"), please visit http://www.technologyreview.com/articles/jan01/TR10_kiczales.html.

Subject: RE: Logging capability in Struts
For things such as logging, it would be a good idea to implement them as an
application level service. Application level services are a concept of
Larry McCay ([EMAIL PROTECTED]). Basically "Services" is interface based
programming for common horizontal services such as logging, object pooling,
etc. For logging there could be a homegrown implementation at first, then
when logging is standardized we could switch the implementation underneath
to use the new mechanism. Also, you could create a Log4j implementation
that uses IBM's logging package if you felt like it. We're holding off on a
full blown introduction until 1.0 is out, so please bear with us.

FYI, the logging API for Java will only be available in JDK 1.4.

Currently, the only logging Struts does is via ServletContext.log() -- which any
servlet can use -- and the log messages go to wherever they are configured for
in your servlet container. You could certainly use something like log4j
yourself.
There has been some discussion of adding a generic Struts logging capability.
However, there is currently a Java Community Process JSR to develop a standard
logging API for Java (which I understand will likely be somewhat similar to
things like LOG4J), so it seems better to wait until that effort is completed.
