[Dev] Application Server 6.0.0, Customized Class Loader

[Miraj Abeysekara]

Hi all,

Since the Application Server 6.0.0 is moving out from the Carbon platform,
the carbon dependencies of the old Application Server's class loader will
get removed. The class loader of the new Application Server 6.0.0 is
implemented using Java 8 by expecting the performance improvements and
better code maintainability. Currently the following features are available
in the Application Server 6.0.0's class loader.


   - Load the global class-loading configurations from
*{APP_SERVER.HOME}/conf/AppLoader/
   *directory. (currently supported configurations: set parent fist
   loading behavior, add globally available runtimes and exclusive runtimes,
   set minimal startup runtime)
   - If any webapp is deployed with its own class-loading configurations
   (specified in *{Webapp.dir}/{Webapp.name}/META-INF/* directory) the
   global values for that webapp were overridden when deploying.
   - Default runtimes are stored in *{APP_SERVER.HOME}/lib/runtimes/ *directory
   which are loaded by the class-loader if required.
   - A webapp can specify a exclusive runtimes which only loaded for that
   webapp


Any other requirements or suggestions are highly appreciated.

Thanks.

1.) Are we support any runtime other than 'Tomcat' OOTB ?

2.) With current C4 we use P2 to install additional runtimes such as CXF,
JavaEE etc. what is our approach to install WSO2 provided additional
runtimes into AS6 ? ( Specially we need to think about UX, in C4 with
P2 this was a one step approach and very convenient )

Thanks !
