"Unsupported binding namespace "". Jaxb with ANT and external binding schema

Hello and thank you for reading this.

I'm trying to use an external binding schema but i keep getting this error: "Unsupported binding namespace "". Perhaps you meant "http://java.sun.com/xml/ns/jaxb/xjc"?" at line 2 of my schema:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element.....

My jaxb binding file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<jxb:bindings xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
version="2.1" jxb:extensionBindingPrefixes="xs">
<jxb:bindings schemaLocation="../src/ro/crispico/tethys/jaxb/schema/Mareva.xsd" node="/xs:schema">
<jxb:bindings node=".//xs:element[@name='time']">
<baseType>
<jxb:javaType name="java.lang.String"/>
</baseType>
</jxb:bindings>
</jxb:bindings>
</jxb:bindings>

I've also tried without the extensionbindingprefixes or with xjc namespace or any other namespaces configuration. Without the binding the generation works ok.

I've verified every similar error that i could find on google but i wasn't able to find the problem. I'm now using the 2.2.4 version of jaxb. In the past i was using jaxb 1 and the generation was working properly. I'm using xjc with ant. Thanks a lot!

[1] I think the error is probably alluding to the baseType

<baseType>
<jxb:javaType name="java.lang.String"/>
</baseType>

jxb:bindings allows extension, but, the alient/extension element must be namespace qualified.

[1.1] You should take out xs as jxb:extensionBindingPrefixes value. Take the whole attribute out.

jxb:extensionBindingPrefixes="xs"

[2] Try this instead this.

Thanks a lot. I don't know how i've missed the jxb in the baseType tag.
It also works like this:
<jxb:bindings node=".//xs:element[@name='time']">
<jxb:baseType>
<jxb:javaType name="java.lang.String"/>
</jxb:baseType>
</jxb:bindings>

Any advantage in using [2] ?

>Any advantage in using [2] ?
As far as I'm concerned, it is a valid construction in compliance with the jaxb 2 binding schema.

The jxb:baseType should be a child of jxb:property. On the spec, it shouldn't be directly under jxb:bindings.
As to the content model of jxb:baseType, both kinds of rendering should be equally fine.
