Here is a request I am sending to EGEE java perfsonar MAs:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"; 
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";

Here is your servers response:

<?xml version="1.0" encoding="utf-8"?><soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";><soapenv:Body><soapenv:Fault><faultcode>soapenv:Server.userException</faultcode><faultstring>org.xml.sax.SAXParseException: 
The prefix &quot;perfsonar&quot; for element &quot;perfsonar:subject&quot; is 
not bound.</faultstring><detail><ns1:hostname 
xmlns:ns1="http://xml.apache.org/axis/";>perfmon1</ns1:hostname></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope>


Then I altered my client to explicitly define the perfsonar namespace
(which the other EGEE servers don't care about either way.)
Here is the request:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"; 
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"; 
xmlns:xsd="http://www.w3.org/1999/XMLSchema";

xmlns:nmwgt="http://ggf.org/ns/nmwg/topology/"; 
xmlns:select="http://ggf.org/ns/nmwg/ops/select/"; type="MetadataKeyRequest"
    >
      <nmwg:metadata id="meta1"
      >
        <nmwg:eventType
        >utilization</nmwg:eventType>
        <perfsonar:subject id="subject1"
        >
          <nmwgt:interface
          >
            <nmwgt:direction

>in</nmwgt:direction></nmwgt:interface></perfsonar:subject></nmwg:metadata>
      <nmwg:data id="outdata1" 
metadataIdRef="meta1"/></message></SOAP-ENV:Body></SOAP-ENV:Envelope>


And your servers response:<?xml version="1.0" 
encoding="utf-8"?><soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";><soapenv:Body><soapenv:Fault><faultcode>soapenv:Server.userException</faultcode><faultstring>java.lang.ClassCastException</faultstring><detail><ns1:hostname 
xmlns:ns1="http://xml.apache.org/axis/";>perfmon1</ns1:hostname></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope>



BTW, I am not asserting that these are 'correct' queries.  Only that they
are getting the response I want from the other EGEE servers.  The correct
response to these queries is a dump of all the 'input' metadata, or about
1/2 of your MA RRD configuration file.
