Dear Wiki user, You have subscribed to a wiki page or wiki category on "Ws Wiki" for change notification.
The following page has been changed by JohnKaputin: http://wiki.apache.org/ws/FrontPage/Woden/WSDLExtensionChanges ------------------------------------------------------------------------------ The {{{ExtensionRegistry}}} methods that handled the {{{ComponentExtensions}}} type have been changed to use {{{ComponentExtensionContext}}} instead. These are the {{{registerComponentExtension}}} and {{{createComponentExtension}}} methods. - ''NOTE:'' Extension properties cannot be treated entirely generically. They can be accessed in a generic way and ''wrapped'' as generic {{{ExtensionProperty}}} objects, but the caller will still need to know what to do with the {{{java.lang.Object}}} returned by the {{{ExtensionProperty.getContent()}}} method - what to cast it to or whether it implements a useful toString() method. Woden should possibly provide some guidance here, like ''"extension implementors should define a suitable {{{toString()}}} method for their extension properties, or for items in an extension property based on a set."''. Then, client applications like GUI tools can at least display extension property content without needing to know what type of object it is. As the Woden API convention is to return typed-arrays for a ''set'' property, applications could just check for an Array type, then call {{{toString()}}} on each element. + ''NOTE:'' Extension properties cannot be treated entirely generically.

Changes to the existing API have been minimized to keep the new extension model largely backward-compatible. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
