JAXB: XJC src-resolve error when importing other schemes

Question

Hi!
I keep getting a src-resolve error from the JAXB binding compiler whenever I try to import other XML schemes into my own.
For example:
I want to use a SignatureType element as defined in the official XML signature schema.
So I imported it into my own schema and use it as follows:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
<xsd:import namespace="http://www.w3.org/2000/09/xmldsig#"
schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd"/>
<xsd:complexType name="PayloadType">
<xsd:sequence>
   <xsd:element name="signature" type="ds:SignatureType" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>However if I run XJC to compile my schema I get this error:
[xjc] [ERROR] src-resolve: Cannot resolve the name 'ds:SignatureType' to a(n) 'type definition' component.I am using JAXB 2.0 EA from the JWSDP 2.0 and XJC is called from an Ant task.
I am pretty new to JAXB and XML schemes, so any help on this topic would be greatly appreciated.

I got the the answer from another forum; it was a proxy problem. Just to inform succeeding readers, here is what I did:
To receive a better error output, I modified my ant buildfile to use the "nv" parameter:
<xjc schema="${path}/.../mySchema.xsd" package="mySchemaPackage" destdir="${path}/.../src">
<arg value="-nv" />
<produces dir="${path}/.../src/mySchemaPackage" includes="**/*.java" />
</xjc>Result:
The XJC compiler gives me a different (better) error message:
[xjc] [ERROR] java.net.ConnectException: Connection timed out: connectSo I looked in my Ant buildfile again to check the proxy settings. I merely used property-tags to define my proxy settings (<property name="http.proxyHost" value="nnn.nnn.nnn.nnn" /> and <property name="http.proxyPort" value="nnnn" /> ) which apparently do not work.
Instead this here does the trick:
<setproxy proxyhost="nnn.nnn.nnn.nnn" proxyport="nnnn"/>Good to now that "nv" might give you a better error report.
