[aspectj-users] HELP: LTW: -javaagent=aspectjweaver.jar or -javaagent:as

["Guofeng Zhang" <guofeng@xxxxxxxxxxxxx>]

Hi,

 

I am studying the load-time weaving.

 

If I use “-javaagent=aspectjweaver.jar”, I got “Unrecognized option: -javaagent=aspectjweaver.jar”.

 

If I use “-javaagent:aspectjweaver.jar” in the following command line:

D:\workdir>D:\workdir\platform\jdk1.5.0\bin\java -cp aspectjsamplesw.jar;aspectjsamples.jar;aspectjweaver.jar;aspectjrt.jar -javaagent:aspectjweaver.jar helloworld.Hello

Exception in thread "main" java.lang.ClassNotFoundException: aspectjweaver.jar

        at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

        at java.security.AccessController.doPrivileged(Native Method)

        at sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:165)

FATAL ERROR in native method: processing of -javaagent failed

 

Can anyone kindly help me what’s wrong with the above line?

 

aspectjsamplesw.jar contains the aspects, and aspectjsamples.jar is a java application that want to be woven by aspectjsamplesw.jar.

 

Thanks
