I've been able to get loadtime weaving going, but not hotswap weaving. I was
wondering if anyone might be able to help me get over this hurdle.
To prepare the environment for HotSwap, I've tried going the following
1. In *$JBOSS_HOME/server/all/conf/bootstrap/aop.xml*, set *enableLoadtimeWeaving* to
true.
2. Placed a copy of the *pluggable-instrumentor.jar* that comes with JBoss AS 6 into
*$JBOSS_HOME/bin*
3. Passed in *-javaagent:pluggable-instrumentor.jar=-hotSwap* as a argument to Java. This
was attemped both by passing it in via an Eclipse JVM parameter, and by editing
*run.conf.bat*.
4. Placed my application's EAR file containing the class to be instrumented into the
*$JBOSS_HOME/server/all/deploy* directory.
5. Placed a file called *prepare-aop.xml* within *$JBOSS_HOME/server/all/deploy*, for the
purposes of preparing a class for HotSwap AOP. It just contains the following:
<aop xmlns="urn:jboss:aop-beans:1.0">
<prepare expr="all(mypackage.MyClass)" />
</aop>
Now, when I start the server, my application gets loaded, I can the URL for MyClass, just
fine. However, my hope is that when I place a file called *myaspects-aop.xml* into
*$JBOSS_HOME/server/all/deploy*, then MyClass would automatically get instrumented with
the aspect below, which just logs that it has been invoked. However, that is not
happening.
<aop xmlns="urn:jboss:aop-beans:1.0">
<aspect class="mypackage.MyAspect"
scope="PER_JOINPOINT">
</aspect>
<bind pointcut="execution( * mypackage.MyClass->*(..) )">
<advice aspect="mypackage.MyAspect" />
</bind>
</aop>
Any insight would be most appreciated!
