Re: [aspectj-users] aspects on org.w3c.dom classes

[Ramnivas Laddad <ramnivas@xxxxxxxxx>]

You advice to call() is working, since (I think) you control
the call site.

Inter-type declarations won't work, unless you make the 
jar files containing the target classes available to the
ajc compiler (using the -injars option). You can fix the problem
by specifying the required jar files with -injars option
(however, do check licenses of the suppliers of those jar 
file. They may not allow you to do so).

There may be alternative solutions depending upon your problem.
