I am a newbie to AOP and have a little experience with mobile agents. I have Aglets working with AspectJ, but would like to be able to use dynamic AOP - I am not sure if it is going to be possible!!!! Initially I am trying Voyager and the standalone version of AOP. As you are required to set the classloader to one that is jboss specific, this affects the running of Voyager. as per the warnings and errors below. Also, if a migrating POJO moves to a new location with it's annotated aspect, would it need to have the aop classloader running on the new location in order for the annotated aspects to work? Finally, when running an annotated aspect you need to specify the directory where the annotated class would be i.e. java -Djava.system.class.loader=org.jboss.aop.standalone.SystemClassLoader -Djboss.aop.class.path=c:\jbossaop2\jboss-aop_1.5.1.GA\docs\aspect-framework\examples\annotated-aspects\ Driver This is also causing a problem.... Any suggestions appreciated!!! ------------------------------------------------------------------------------------- Voyager also has the following resourceloading api http://www.ifi.unizh.ch/ddis/staff/vorburg/doc/api/Orbpro/com/objectspace... ------------------------------------------------------------------------------------- [warn] Could not find class com.ms.security.PolicyEngine that com.objectspace.vo yager.loader.MSVoyagerClassLoader references.
