Re: [aspectj-users] create pointcuts to external library code

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

the weaver has to be able to process the code for the joinpoints in
order to match/weave them and so insert the advice calls.  If  those
classes are inside the JRE classes, AspectJ doesn't normally get to
see them.  The simplest thing is to compile time weave the
rt.jar/classes.jar

ajc -inpath rt.jar -outjar rt_woven.jar MyAspect.java

and then use the woven version (syntax something like this):

java -Xbootclasspath/p:rt_woven.jar Something

cheers,
Andy
