Class not found when using OSGI class loader
--------------------------------------------
Key: WICKET-2530
URL: https://issues.apache.org/jira/browse/WICKET-2530
Project: Wicket
Issue Type: Bug
Components: wicket-guice
Affects Versions: 1.4.2
Reporter: Marc-Andre Houle
Fix For: 1.4.3
I am presently using Guice and OSGi. Our OSGi platform is used as a plugin
platform for our web application. We load the OSGi framework and load it into
Guice as a service provider. The plugins can be used to return panel or other
wicket components that are then used in the pages.
When one of the plugins components have a Guice injection, there is a class not
found problem that is seen when trying to use injected stuff :
org.apache.wicket.guice.GuiceProxyTargetLocator.locateProxyTarget(GuiceProxyTargetLocator.java:79)
This class not found is because the Guice injector is trying to access the
class directly by making a Class.forName. Since using an OSGi framework, the
classloader is not capable of returning the class correctly.
To solve this issue, the wicket-guice integration should use the wicket
Classes.resolveClass static method that is using a class resolver that can be
changed and check for class in other class loader.
