Hi
Michael,
Did you compile the
aspect or just put the source in that directory? With load-time weaving, you
still need to compile your aspects into bytecode, but you don’t need to
“weave” with the classes at build-time. Try compiling your aspect and putting
the result in the same directory, e.g.,
cd
WEB-INF\classes
ajc
com\test\MyAspect.aj
(of course for
production use, I’d recommend compiling with an ant task and deploying this
class file with the rest of your application…) 10x

exception while using LTW.
Hi
everybody!
I'm using aspectj M4 version and trying to enable
load-time weaving for my application. The application is web application.
I
have created aop.xml under
WEB-INF/classes/META-INF.
Here is the
file:
<aspectj>
<aspects>
<aspect
name="com.test.MyAspect"/>
</aspects>
<weaver options="-XlazyTjp
-showWeaveInfo">
<include
within="com.test.*"/>
</weaver>
</aspectj>
I'm using weaving agent through
the JVMTI.
The trouble is that weaver is
unable to find MyAspect, although it's present in
directory WEB-INF/classes/com/test.
If I understand correct, I just
have to place .aj file in the classpath of my application, and to declare it
in aop.xml … So what can be wrong?
Here is the
stack trace:
warning Register definition failed
-- (RuntimeException) Cannot register non aspect: @missing@ ,
com.test.MyAspect

@missing@ , com.test.MyAspect
