I'm haing a problem of somethign not unmarshaling corrdctly. I have a
string that contains the folowing (pretty printed here):

But when I run this code:
code segment from one funtion
        JAXBContext jc = JAXBContext.newInstance(
            "msg.pkg");
        Unmarshaller u = jc.createUnmarshaller();
        Object dds = (Object) u.unmarshal(new ByteArrayInputStream(
            ddsMsg.getBytes()));
               JAXBContext jc =
JAXBContext.newInstance("csds.message:org.mitre.dds.jaxb");
        StringWriter result = new StringWriter();
        Marshaller m = jc.createMarshaller();;

code segment from another
        JAXBContext jc =
JAXBContext.newInstance("csds.message:org.mitre.dds.jaxb");
        StringWriter result = new StringWriter();
        Marshaller m = jc.createMarshaller();;
        m.marshal(msgObj, result);
        msgStr = result.toString();

msgStr has value (pretty printed):
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns6:advertiseSS advertisementID="1b094a9d-063b-409b-8a3b-923061a5c983"
userID="peer" commandDateTime="2006-05-25T09:49:56.593-04:00"
xmlns:ns4="http://metadata.dod.mil/mdr/ns/DDMS/1.2/"
xmlns:ns3="urn:us:gov:ic:ism:v2"
xmlns:ns5="http://mitre.org/DDS/metadata"
xmlns:ns2="urn:us:gov:dod:army:cerdec:jbfsa:csds:r1"
xmlns:ns6="http://mitre.org/DDS">
    <hopCount>0</hopCount>
</ns6:advertiseSS>

It's like it did not use the value in the beginning. Also some of the
required elements are missing so would not even pass schema check.
