Hello there, I have been trying to use the LTW with a simple test project
that runs on Jetty and I keep getting the error shown bellow, this happens
when running on Jetty but the aspects and weaving works fine when running
on a regular (non servlet).
Can you guys please help me set up a servlet app to work with the load time
weaver?, thanks in advance for your help!
