Clint Popetz commented on JBSEAM-3505:
--------------------------------------
I've implemented this, patch attached.
The patch does the following:
* move runtime-classloading-specific stuff from JavassistInstrumentor into WicketClassLoader
* make JavassistInstrumentor usable from outside classes by making its constructor take a Javassist classpool, and make instrumentClass return the CtClass it creates, and be public.
* Make WicketClassLoader use that interface.
* Create a new WicketInstrumentationTask class that also uses this interface. This is an ant task (see below for example usage.)
* Rather than havingthe classloader call WickeComponent.create, since that won't work for the case that the instrumentation is not done by the classloader, have JavassistInstrumentor create a <clinit> to do that.
* Make WicketFilterInstantiator not know about JavassistInstrumentor. It just knows about WicketClassLoader.
* build the wicket ant task into lib/jboss-seam-wicket-ant.jar
Example usage of the task would be:
<target name="instrumentweb">
<taskdef name="instrumentWicket" classname="org.jboss.seam.wicket.ioc.WicketInstrumentationTask">
<classpath>
<pathelement location="lib/jboss-seam-wicket-ant.jar"/>
<pathelement location="lib/jboss-seam.jar"/>
<pathelement location="lib/jboss-seam-wicket.jar"/>
<pathelement location="lib/javassist.jar"/>
</classpath>
</taskdef>
<path id="web.classpath">
<path refid="build.classpath"/>
<pathelement location="classes/web" />
</path>
<instrumentWicket outputDirectory="${war.dir}/WEB-INF/classes">
<classpath refid="web.classpath"/>
<fileset dir="classes/web"/>
</instrumentWicket>
</target>
Note that there are two nested elements for this task:
(1) a classpath
(2) a set of classes to instrument
and one attribute (where to put the output classes.)

> Currently instrumentation is done through a custom classloader. If it was done at build time, the classes could be deployed to WEB-INF/classes
