Hello everybody,
When I start my application (console) with the weaver agent, without JMX,
everything is fine, with JMX the aspect configuration is not found. I use
Aspectj 1.7.3 (I tried version 1.7.0 and 1.7.1).
The aspect configuration is done by the file META-INF/aop.xml which contains
the weaver options:
-Xlint:ignore -Xset:weaveJavaPackages=false,weaveJavaxPackages=false
I searched and tried several solutions:
- The aop.xml is not in the right place: moving the aop.xml in the
sources in META-INF, generating with -outxml
- The aspect configuration name: renaming aop.xml to aop-ajc.xml
- There is classloader problems: I added the option
-Djava.system.class.loader=org.aspectj.weaver.loadtime.WeavingURLClassLoader
- AspectJ can't find the jar with aspect: I added the options
"-Daj.class.path=.\libs\*"
"-Daj.aspect.path=.\libs\org.iiter.aspects.monitoring-0.0.1-SNAPSHOT.jar"
The problem is still here.
It seems that the classloader are different:
sun.misc.Launcher$AppClassLoader without JMX,
javax.management.remote.rmi.NoCallStackClassLoader with JMX. Could it be the
cause?
My projects are built with Maven. For the aspect, I use this plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>${aspectj.plugin.version}</version>
<configuration>
<complianceLevel>${maven.compiler.source}</complianceLevel>
<source>${maven.compiler.source}</source>
<target>${maven.compiler.target}</target>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
<dependencies>
<!-- Ensure aspectj tools version used by
compiler is the same version used as dependency. Avoids warning -->
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjtools</artifactId>
<version>${aspectj.rt.version}</version>
</dependency>
</dependencies>
</plugin>
All my jars (aspect, application and frameworks like slf4j and Spring) are
in a "libs" directory.
When I start my application without JMX:
java
-javaagent:.\libs\aspectjweaver-1.7.3.jar
-cp ".\libs\application.jar;.\libs\*"
-Xms64m -Xmx512m -XX:MaxPermSize=128m
-Djava.system.class.loader=org.aspectj.weaver.loadtime.WeavingURLClassLoader
-Daj.weaving.verbose=true -Dorg.aspectj.weaver.showWeaveInfo=true
"-Daj.class.path=.\libs\*"
"-Daj.aspect.path=.\libs\org.iiter.aspects.monitoring-0.0.1-SNAPSHOT.jar"
-Dlogback.configurationFile=file:.\logback.xml
org.iiter.application.Launcher
I get this logs:
