[jboss-user] [JBoss AOP] - AOP for JBoss web service

Franklin Webber [https://community.jboss.org/people/eutaxy] created the discussion "AOP for JBoss web service" To view the discussion, visit: https://community.jboss.org/message/725146#725146 -------------------------------------------------------------- I'm trying to use JBoss AOP to instrument an existing web service that runs in JBoss AS 5.1. Unfortunately, I'm unable to get AOP to work within JBoss, despite having read a substantial amount of documentation and done a substantial amount of fiddling around with the "injboss" example from the AOP distribution.  (In contrast, I have been able to get AOP to work with standalone Java programs, outside JBoss.) Can anyone tell me why the following steps fail to demonstrate compile-time AOP instrumentation? (I've also tried one of the "injboss" examples for run-time weaving, which also does not work, but I'm guessing the compile-time example will be simpler by not involving the Aspect Manager or a Java Agent.) -- unzip jboss-5.1.0.GA-jdk6.zip -- unzip jboss-aop-2.1.8.GA.zip -- upgrade JBoss using the instructions in jboss-50-install/ReadMe-AS5.txt -- modify docs/aspect-framework/examples/injboss/build-jboss5.xml ,    setting jboss.dir , jboss.server.config , and jboss.classpath -- run ant on build-jboss5.xml for the deploy-basic-ct-war target -- run jboss -- look at aopexample/index.jsp in a browser. The result is ClassNotFoundException: org.jboss.injossaop.lib.SimpleInterceptor . I note that this is similar to a problem described by poster Karen Greene several years ago in https://community.jboss.org/message/446338#446338#446338 https://community.jboss.org/message/446338#446338 . She says she resolved the problem but does not say how. I tried resolving the problem by adding aopexamplelib.jar to the JBoss AS class-path. The result is NoClassDefFoundError:  org/jboss/aop/advice/Interceptor . I then tried adding both aopexamplelib.jar and jboss-aop-single.jar from the AOP distribution to the JBoss AS class-path.  The result is NoSuchMethodError: org.jboss.logging.util.LoggerPluginWriter.<init> . I do not know how to resolve this, as I see the named class in jboss-aop-single.jar . Got an explanation? Useful advice? Helpful insight? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/725146#725146] Start a new discussion in JBoss AOP at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
