You are aware of the reloading classloader plugin for cocoon? :) It
is using JCI to do the reloading
see http://cocoon.zones.apache.org/daisy/cdocs-rcl-plugin/g1/1297.html
...and can auto-instrument the javaflow classes.
@Thorsten: What needs to be done that Javaflow classes get reloaded
using the RCL plugin AND are being instrumented?
"Torsten"!! ;)
sorry :-)
though I know what you mean (Rainhard, Reinhardt, ...)
And what configuration is necessary for production so that classes are
"only" instrumented?
For javaflow all you need is to use this store. For both - compiling or
reloading. Of course it would be good to configure the packages that
should be instrumented. I can add that to that store directly if you want.
http://jakarta.apache.org/commons/sandbox/javaflow/apidocs/org/apache/commons/javaflow/stores/JavaflowResourceStore.html
sorry, I'm a confused. What do you mean by "this" and "that" store. The current
implementation is
org.apache.commons.jci.listeners.ReloadingListener rl =
new CocoonReloadingListener();
rl.addReloadNotificationListener(classloader);
fam.addListener(directory, rl);
and if I look into CocoonReloadingListener() which extends
org.apache.commons.jci.listeners.ReloadingListener I find that it creates stores
of type MemoryResourceStore.
Am I right that, in order to support instrumentation for Javaflow, I have to
override the default behaviour and create stores of type JavaflowResourceStore
instead?
This brings me to my other question: The cocoon-rcl-plugin is only useful at
development time. What options to instrument Javaflow classes for production use
do we have?
