I am trying to generate Java classes to bind xml to objects using castor. The piece of xml that I am trying to bind is a spring xml file so i took the dtd and generated the xsd using the tools castor provided, but once I attempt to generate the source files i recieve the following error
java.lang.IllegalArgumentException: Duplicate name found as a class member: _key
Here is the xsd file that I have generated:
<?xml version="1.0" encoding="UTF-8"?>

Has anyone run into a similiar problem and know of any way to fix this?
For the concrete castor problem you should provide more information, I guess. It seems there’s a duplicate field, so go ahead and remove each “key” attribute one by one until it starts working.
But it is a strange thing you are trying to do. Spring’s DTD/XSD are meant to provide XML configuration – they aren’t supposed to represent objects. If you want to configure spring with code rather than xml, use javaconfig.
