How to Customize and Extend opentaps 2 with your own OSGi Bundle
Ok, you've been patient and reading through all the other tutorials. But at some point, you've probably wondered -- what's the big idea here?
This tutorial will show you.
The most important thing for successful enterprise software is modularity: Separate and maintainable modules for each part of the application. OSGi lets you extend and customize your application with your own bundle. Even better, it lets you manage those bundles in real time, so you can manage your application by loading and unloading bundles from the Geronimo console.
In this tutorial, we will add security permissions to our opentaps 2 Notes application and then show you how to implement an OSGi bundle which overrides the base permission with your own. You can then see how you can deploy and undeploy the bundle in real time to change the security permissions of your system without restarting the server.
