All Implemented Interfaces:

IPoolable

public class PageSpecificationResolver
extends AbstractSpecificationResolver

Performs the tricky work of resolving a page name to a page specification. The search for pages in the application namespace is the most complicated, since Tapestry searches for pages that aren't explicitly defined in the application specification. The search, based on the simple-name of the page, goes as follows:

• As declared in the application specification
• simple-name.page in the same folder as the application specification
• simple-name page in the WEB-INF/servlet-name directory of the context root
• simple-name.page in WEB-INF
• simple-name.page in the application root (within the context root)
• simple-name.html as a template in the application root, for which an implicit specification is generated
• By searching the framework namespace
• By invoking ISpecificationResolverDelegate.findPageSpecification(IRequestCycle, INamespace, String)

Pages in a component library are searched for in a more abbreviated fashion:

• As declared in the library specification
• simple-name.page in the same folder as the library specification
• By searching the framework namespace
• By invoking ISpecificationResolverDelegate.findPageSpecification(IRequestCycle, INamespace, String)
