Problem to Xquery a document from xindice collection

[johan bos]

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
