 Dependency conversion to XML entity class Wsperson.java, this guy can't be placed in the pages directory, or he will "hang up"

Through the annotations, this guy is already hundred poison, can easily convert to XML file.
 
Click "PERSONFIND/1" on the page to jump to the Personfind page, as shown below:
 
 
In this context, Tapestry created a standard as a rest-like Web service.
 
********************************************************************************************************
 
The point is, as said above: Wsperson.java if placed under the pages package, it will report an exception error: Class Com.changhongit.andy.pages.ws.WsPeople has been transformed and May is directly instantiated.
 
said that this class has been converted can not be directly instantiated, which is probably why the Tapestry page class are placed in pages under the package, must have done some processing, as to how to deal with, sorry I have not read the source!
