Examples of org.apache.tapestry.IResourceResolver

org.apache.tapestry.IResourceResolver
An object which is used to resolve classes and class-path resources. This is needed because, in an application server, different class loaders will be loading the Tapestry framework and the specific Tapestry application.
The class loader for the framework needs to be able to see resources in the application, but the application's class loader is a descendent of the framework's class loader. To resolve this, we need a 'hook', an instance that provides access to the application's class loader.
To more easily support OGNL, this interface now extends {@link ognl.ClassResolver}. @author Howard Lewis Ship @version $Id: IResourceResolver.java 243791 2004-02-19 17:38:13Z hlship $
