Re: [aspectj-users] Compile time weaving happening, LTW not working

[Andy Clement <andrew.clement@xxxxxxxxx>]

Does your classpath really say:

CLASSPATH=%CLASSPATH%;E:\Workspace\AspectJ_Proj\build\aspect.jar.jar;E:\Workspace\AspectJ_Proj\lib\aspectjrt.jar

shouldnt that just be aspect.jar rather than aspect.jar.jar?

You don't need to set ASPECTPATH.  The existence of META-INF/aop.xml
in the jar file is enough to find the aspects.
