Unsupported binding namespace "http://annox.dev.java.net"

I am tring to generate java source code from xsd file with annotations. For this I have written
XSD having following declarations in XSD file.

xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
jaxb:version="2.1"
xmlns:annox="http://annox.dev.java.net"
xmlns:s="http://annox.dev.java.net/org.hibernate.search.annotations"
jaxb:extensionBindingPrefixes="annox">

But when I tried to compile this schema with XJC its give me error that Unsupported binding namespace "http://annox.dev.java.net". And when I tried to open this URL(http://annox.dev.java.net) in browser the its show me Internet Explorer cannot display the webpage. Is the support for annox has been removed? Or there is another way to implement annox. Please help. Thanks in advance.
