+This directory contains a script "aj" to demonstrate load-time weaving. Java

+classes on the CLASSPATH are loaded and woven with aspects on the ASPECTPATH.

+This feature is only supported on JDK 1.4 and later.

+

+--To compile the tracing example--

+

+ ant -f ../build.xml tracing-lt

+

+--To run the example--

+

+ set CLASSPATH to include "../jars/tracingApp.jar"

+

+ aj tracing.ExampleMain

+

+--To run the example with tracing--

+

+ set ASPECTPATH=../jars/tracingLib.jar

+

+ aj tracing.ExampleMain

+
