Steve, The idea of writing a custom JXPathBeanInfo is not that bad. On the other hand, I don't see why I could not update the introspector to recursively acquire property descriptors for all those parent interfaces.
The only issue with the use of the JXPathBeanInfo for the interface is that the _only_ properties available via the XPaths will be those on the interface. Any additional properties declared by the class directly will be inaccessible. Would it be possible to get JXPathBeanInfo for the object's class, not the interface? - Dmitri ----- Original Message ----- From: "Stephen Bartlett" <[EMAIL PROTECTED]> To: "'Jakarta Commons Developers List'" <[EMAIL PROTECTED]> Sent: Thursday, June 13, 2002 7:32 PM Subject: RE: [JXPATH] Difference in introspection > Dmitri, > > I have a NodePointerFactory impl that uses the JXPathIntrospector to create > a JXPathBeanInfo object for an Interface.
