> [PATCH] Reloading classloader in Cocoon 2.2
> -------------------------------------------
>
> Key: COCOON-1929
> URL: http://issues.apache.org/jira/browse/COCOON-1929
> Project: Cocoon
> Issue Type: Task
> Components: * Cocoon Core
> Affects Versions: 2.2-dev (Current SVN)
> Reporter: Maurizio Pillitu
> Attachments: cocoon-core-r469213.diff, cocoon-r469167.diff,
> cocoon.diff
>
>
> The attached patch provides a first implementation to enable reloading
> classloader configuration into the sitemap, using the sitemap syntax used in
> blocks/cocoon-core-sample/cocoon-core-main-sample/src/main/resources/COB-INF/sitemap.xmap.
> Referring to CocoonGT 2005 Torsten's code, I moved all the JCI listener
> configuration into the ReloadingClassLoaderFactory class, that is in charge
> to parse the classloader configuration (filled by AvalonUtils class) and
> instanciate all the JCI listeners.
> The TreeProcessor component is subscribed to the JCI listeners, in order to
> reload the component definitions when a file change event is triggered.
> The patch provides also a sample :
> http://localhost:8888/blocks/cocoon-core-main-sample/reloading/
> Try to change MyGenerator.java and compile it into
> blocks/cocoon-core-sample/cocoon-core-main-sample/target/classes (default
> eclipse location); if you need to change the location of the .class folder,
> edit the cocoon-core-main-sample sitemap.xmap.
> core.
> Obviously there are many parts of the code that can be optimized.
> The patch has been applied on revision 453682.
> NOTE!
> 1. I decided to provide the reloading class functionality only for dev mode,
> so, in order to get it working, you need to run the cocoon application with
> -Dorg.apache.cocoon.mode=dev
> 2. The patch depends on a bugfix on Commons JCI
> (https://issues.apache.org/jira/browse/SANDBOX-174), so it's necessary to
> build jci-core from trunk; the patch will update the cocoon-bootstrap
> dependency to jci.
