Re: [aspectj-users] aspectJ + tomcat5

[Wes Isberg <wes@xxxxxxxxxxxxxx>]

The compiler adapter required a dest dir to track its status.
The dest dir is the directory that classes are output to,
but Tomcat JSP compilation uses a Javac Ant task invocation
that does not specify the dest dir.

To support Tomcat, this requirement was removed after 1.1.1.
To get the fix, compile taskdefs module src (not testsrc) and
either put that jar in front on the classpath or remove/replace
the taskdefs in your aspectjtools.jar.  For convenience
I've attached the latest classes (since they're small).

Fair warning: I haven't tested this approach.  Please let us
know how it works out.
