perfSONAR User Q&A and Other Discussion

[Sven Ubik <>]

Hi,

we tried to upgrade to perfSONAR HEAD Java version. It accepts messages
in old format with "perfsonar" namespace, but the same request in the
new "nmwg" namespace fails:

     [java] End point:
http://localhost:8080/axis/services/MeasurementArchiveService
     [java] Request file:
/usr/local/sonarHEAD/perfsonar/schema/example-instances/sonar/SetupDataRequest-FilterRRDSelect-Cesnet.xml
     [java] Response file:
/usr/local/sonarHEAD/perfsonar/conf/response.xml
     [java] SOAPClient.makeRequest: General exception encountered by
client
     [java] AxisFault
     [java]  faultCode:
{http://schemas.xmlsoap.org/soap/envelope/}Server.userException
     [java]  faultSubcode:
     [java]  faultString: java.util.EmptyStackException


Both messages are attached as request.xml and request2.xml.

Can anybody suggest me where can be the problem?

Thanks.

Regards,

Sven Ubik
