Problem to Xquery a document from xindice collection

Hello Everyone,

Here my problem,
I can connect and create a collection (mail)  in xindice 1.1 (from
within my
servlet (tomcat 5))
I can add document to this collection (the ugly browser let me see them)

but when i try to make a query using the example function for quering
xindice, i got an error such as below: (some of the message are from my
debug)


trying to register database
Database xmldb:xindice://localhost:8080/db is connected
Collection xmldb:xindice://localhost:8080/db is connected
Collection mail already created
org.xmldb.api.base.XMLDBException: org.apache.xmlrpc.XmlRpcException:

Query /mail/Message/from/Address/[name='dariusjbos'] return an error
XML:DB Exception occured 1 org.apache.xmlrpc.XmlRpcException: Error
Compiling XPath Expression: Une étape d'emplacement était attendue après
le
jeton ''/'' ou ''//''.

the xml document i try to query look like this:
<?xml version="1.0" encoding="UTF-8"?>
<Message xmlns="URN:ietf:params:email-xml:"
rfc822="URN:ietf:params:rfc822:">
    <date>Mon Aug 15 19:03:47 CEST 2005</date>
    <from>
        <Address>
            <adrs>mailto:[email protected]</adrs>
            <name>dariusjbos</name>
        </Address>
    </from>
</Message>

find after the function i use to query the mail collection under db:

public static void queryCollection()throws Exception {
    	Collection col = null;
        try {
           String driver =
"org.apache.xindice.client.xmldb.DatabaseImpl";
           Class c = Class.forName(driver);

           Database database = (Database) c.newInstance();
           DatabaseManager.registerDatabase(database);

           col =
DatabaseManager.getCollection("xmldb:xindice://localhost:8080/db/mail");

           String xpath = "//Message/from/Address/[name='dariusjbos']";
           XPathQueryService service =
              (XPathQueryService) col.getService("XPathQueryService",
"1.0");
           ResourceSet resultSet = service.query(xpath);
           ResourceIterator results = resultSet.getIterator();
           while (results.hasMoreResources()) {
              Resource res = results.nextResource();
              System.out.println((String) res.getContent());
           }
        }
        catch (XMLDBException e) {
           System.err.println("XML:DB Exception occurred " + e.errorCode
+
"" + e.getMessage());
        }
        finally {
           if (col != null) {
              col.close();
           }
        }
}

please I really need to pass this problem (deadline in 3 days)

thanks in advance
