Reloading Cocoon2 / Custom Generator
Hello,
i was wondering if it is possible to reload cocoon or a custom build
generator after its been recompiled without restarting tomcat. If yes,
i'd like to know how, and if not, then id like to know if theres another
way to speed up the compiling / testing process somehow because always
waiting about 30 seconds (restarting tomcat, reloading cocoon..) after
changing the java code slows down my dev. cycle quite a bit.
Tanks a lot, if you can help, you make my life easiert ;)

i am not sure if the SimpleClassLoader can load from jars, but if it can it
could work, the classloader is the object that actually gets classes from
disk to the jvm, so if the SimpleClassLoader can load the classes from a
jar, then it should work.
please tell me if you can find a Classloader that can load from jars, i
would be thankful!

I have a jar with all the classes my generator employs in it. Is there
no way to get cocoon to reload every class that has changed from disk in
this jar?

RE: Reloading Cocoon2 / Custom Generator

all classes are loaded by a classloader, by creating your own classloader
you can nullify it after use and the class will have to load from disk
again, included is a example of a custom classloader, here is an example of
how to use it:
SimpleClassLoader sc = new SimpleClassLoader( "/opt/java/classes" );
try {
somecoolclass cool =
(somecoolclass)(sc.loadClass( "somecoolclass.class" )).newInstance();
cooo.doCoolThings();
}
catch (Exception e) {
System.out.println( "aarrgggghhhh, classloader failed = " +
e.getMessage() );
e.printStackTrace();
}
sc = null;
so you will have to wrap the functionality you want to be dynamicaly
reloaded in the somecoolclass.class and create a generator wrapper that uses
the classloader to load your class and then kill the classloader at the end
of each execution run.
