aj
[Options
] [[arg...
]]
The
aj command runs Java programs in Java 1.4 or
later by setting up
WeavingURLClassLoader
as the system class
loader, to do load-time bytecode weaving.
The arguments are the same as those used to launch the Java program.
Users should define the environment variables
CLASSPATH
and
ASPECTPATH
.
For more information and alternatives for load-time weaving, see Load-Time Weaving.
Example 2.5. A simple example
Use ajc to build a library, then weave at load time
REM compile library ${ASPECTJ_HOME}\bin\ajc.bat -outjar lib\aspects.jar @aspects.lst REM run, weaving into application at load-time set ASPECTPATH=lib\aspects.jar set CLASSPATH=app\app.jar ${ASPECTJ_HOME}\bin\aj.bat com.company.app.Main "Hello, World!"
