JaxB Compile Error: Failed to read imported schema document

[Yair Ogen]

hi i'm trying to compile the CD_DataBase.xsd schema (using the JaxB that I got from the JWSDP found at Sun's site) which references to an Album element in Album.xsd
For some reason, my xjc task falls when trying to read the imported schema.
here are the schemas':
---------------------------------------------------
Album.xsd
---------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.bll.co.il"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
jaxb:extensionBindingPrefixes="xjc"
jaxb:version="1.0"
elementFormDefault="qualified">
<xsd:annotation>
<xsd:appinfo>
<jaxb:globalBindings>
<xjc:serializable/>
</jaxb:globalBindings>
</xsd:appinfo>
</xsd:annotation>
<xsd:element name="album">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="description" type="xsd:string"/>
<xsd:element name="producer" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
---------------------------------------------------
CD_DataBase.xsd

jaxb:extensionBindingPrefixes="xjc"
jaxb:version="1.0"

<xsd:import namespace="http://www.bll.co.il" schemaLocation="Album.xsd"/>
<xsd:annotation>
<xsd:appinfo>
<jaxb:globalBindings>
<xjc:serializable/>
</jaxb:globalBindings>
</xsd:appinfo>
</xsd:annotation>
<xsd:element name="CD">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="artist" type="xsd:string"/>
<xsd:element ref="alb:album"/>
</xsd:sequence>
<xsd:attribute name="title" type="xsd:string" use="required"/>
</xsd:complexType>
</xsd:element>
</xsd:schema>
can any one help?
even if it works, will jaxb compilr the referenced schema (album.xsd) to java classes every time i use it (in other schemas' that are using it)?
Thank's,
