(However I do receive a defined FieldValidationException when I pass a bad arg i.e. a MAC with ":" rather than just hex digits or any invalid mac value such as the last example below where I switched the order of args passed.) Below is a tcpTrace of two requests/response. Most information I have seen referring to NullPointerException has to do with the installation on the server such as jdk version, classpath, etc... The server I am testing against is a new 'live' installation so this also makes me wonder if it may have to do with the server rather than my request. However since I am receiving proper validation error it appears that the web service is functioning properly at least to some degree and may be the way my request is formatted. Any help I receive from the developers of the web service is sparse and slow. So any suggestions would be greatly appreciated. -- Jim <tcpTraceLog tcpTraceVersion='0.8.0.712' xmlns='http://www.pocketsoap.com/tcptrace/xmlformat/01' xmlns:xsd='http://www.w3.org/1999/XMLSchema' xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance'> <logStarted xsi:type='xsd:timeInstant'>2005-04-12T16:54:49-05:00</logStarted> <connection> <loggedAt xsi:type='xsd:timeInstant'>2005-04-12T16:59:51-05:00</loggedAt> <connectionOpened xsi:type='xsd:timeInstant'>2005-04-12T16:55:08-05:00</connectionOpened> <connectionClosed xsi:type='xsd:timeInstant'>2005-04-12T16:59:51-05:00</connectionClosed> <source>127.0.0.1</source> <destination>alopa.imctv.com:80</destination> <bytesClientToServer>683</bytesClientToServer> <bytesServerToClient>614</bytesServerToClient> <clientData>POST /axis/services/InboundService?wsdl HTTP/1.1 Host: localhost:8080 Accept-Charset: UTF-8, UTF-16;q=0.8, iso-8859-1;q=0.8 Accept-Encoding: deflate Content-Type: text/xml; charset=UTF-8 SOAPAction: "" User-Agent: PocketSOAP/1.4.3 Content-Length: 422 <S:Envelope S:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:a="http://api.metaprov.alopa.com"; xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:XS="http://www.w3.org/2001/XMLSchema"; xmlns:XI="http://www.w3.org/2001/XMLSchema-instance";> <S:Body><a:getDetails><in0 XI:type="XS:string">Cable Home</in0> <in1 XI:type="XS:string">0000cac5166d</in1> </a:getDetails> </S:Body></S:Envelope></clientData> <serverData>HTTP/1.1 500 Internal Server Error Content-Type: text/xml; charset=utf-8 Transfer-Encoding: chunked Date: Tue, 12 Apr 2005 20:54:22 GMT Server: Apache Coyote/1.0 1b1 <?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.NullPointerException</faultstring> <detail/> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope> 0 </serverData> </connection> <connection> <loggedAt xsi:type='xsd:timeInstant'>2005-04-12T17:05:24-05:00</loggedAt> <connectionOpened xsi:type='xsd:timeInstant'>2005-04-12T17:00:41-05:00</connectionOpened> <connectionClosed xsi:type='xsd:timeInstant'>2005-04-12T17:05:24-05:00</connectionClosed> <source>127.0.0.1</source> <destination>alopa.imctv.com:80</destination> <bytesClientToServer>682</bytesClientToServer> <bytesServerToClient>948</bytesServerToClient> <clientData>POST /axis/services/InboundService?wsdl HTTP/1.1 Host: localhost:8080 Accept-Charset: UTF-8, UTF-16;q=0.8, iso-8859-1;q=0.8 Accept-Encoding: deflate Content-Type: text/xml; charset=UTF-8 SOAPAction: "" User-Agent: PocketSOAP/1.4.3 Content-Length: 421 <S:Envelope S:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:a="http://api.metaprov.alopa.com"; xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:XS="http://www.w3.org/2001/XMLSchema"; xmlns:XI="http://www.w3.org/2001/XMLSchema-instance";> <S:Body><a:getDetails><in0 XI:type="XS:string">0000cac5166d</in0> <in1 XI:type="XS:string">CableHome</in1> </a:getDetails> </S:Body></S:Envelope></clientData> <serverData>HTTP/1.1 500 Internal Server Error Content-Type: text/xml; charset=utf-8 Transfer-Encoding: chunked Date: Tue, 12 Apr 2005 20:59:55 GMT Server: Apache Coyote/1.0 2ff <?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>com.alopa.metaprov.api.FieldValidationException: device-mac validation failed. </faultstring> <detail> <ns1:fault xsi:type="ns1:FieldValidationException" xmlns:ns1="http://api.metaprov.alopa.com";> <ns1:errorCode xsi:type="xsd:string">3000</ns1:errorCode> <ns1:errorMessage xsi:type="xsd:string">device-mac validation failed. </ns1:errorMessage> </ns1:fault> </detail> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope> 0 </serverData> </connection> <logStopped xsi:type='xsd:timeInstant'>2005-04-12T17:38:51-05:00</logStopped> </tcpTraceLog>
