hibernate schema export SAXParser error

[santosh kulkarni]

I am getting the following error while running the schema export ant task.
Hibernate version 2.03. If anybody has any idea about this please post a reply. It appears as if the parser is complaining that the xml file isn't conforming to the DTD but I am puzzled why. Some other vital information is at the end of the stack trace. I am willing to send any more information if someone would like to help me.

please scroll down a little for complete stacktrace
SEVERE: Error parsing XML: D:\<path shortened>\AccountInformationTypeImpl.hbm.xml(32)
org.xml.sax.SAXParseException: Attribute "access" must be declare
d for element type "property".



The .hbm.xml file was generated by XDoclet 1.2.1.
here is an excerpt from the .hbm.xml file.

Now that is wierd. hibernate-mapping-2.0.dtd does define an implied attribute of the PROPERTY element calles ACCESS. And the hibernate docs state that one of the anticipated values is "property". I can't say why this is happening, but the obvious way round it is to delete the access attribute. I'd post this on the forum at hibernate's site - see if one of the developers can explain. Let us know what you find out.

Thanks Paul for the reply. One of my colleagues had the same suggestion of removing the access tags, it does work. I have not seen any reply to my post on the hibernate forum yet. Now I am stuck at hyperjaxb not creating hibernate xdoclet tags for public static classes , but that goes into another post:-)

If you really mean HyperJAXB, would you please provide more details?
