More Data...... Using the tcpmon application, I was able to grab all of the data being swapped between the client and server.
For some reason, Axis (server, java) returns the returns the response "chunked" for the C++ Client but not for the Java client. I assume the delay is due to the connection not closing correctly. The C++ app probaly returns after the connection times out??? Again, any help is appreciated -Ben Here is the data intercepted with tcpmon:.... ================================= FROM THE JAVA CLIENT ================================= Listen Port: 8888 Target Host: 127.0.0.1 Target Port: 8080 ==== Request ==== POST /file_manager/services/EchoCaps HTTP/1.0 Content-Type: text/xml; charset=utf-8 Accept: application/soap+xml, application/dime, multipart/related, text/* User-Agent: Axis/1.1RC2 Host: 127.0.0.1 Cache-Control: no-cache Pragma: no-cache SOAPAction: "" Content-Length: 473 <?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> <ns1:capitalize soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:ns1="EchoCaps"> <inputString xsi:type="xsd:string">String from the java client</inputString> </ns1:capitalize> </soapenv:Body> </soapenv:Envelope> ==== Response ==== HTTP/1.1 200 OK Content-Type: text/xml;charset=utf-8 Date: Fri, 28 May 2004 20:17:24 GMT Server: Apache-Coyote/1.1 Connection: close <?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> <ns1:capitalizeResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:ns1="EchoCaps"> <EchoCaps xsi:type="xsd:string">STRING FROM THE JAVA CLIENT</EchoCaps> </ns1:capitalizeResponse> </soapenv:Body> </soapenv:Envelope> =================== FROM THE C++ CLIENT.......... =================== Listen Port: 8888 Target Host: 127.0.0.1 Target Port: 8080 ==== Request ==== POST /file_manager/services/EchoCaps HTTP/1.1 Host: 127.0.0.1 Content-Type: text/xml; charset=UTF-8 SOAPAction: "EchoCaps#capitalize" Content-Length: 439 <?xml version='1.0' encoding='utf-8' ?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <SOAP-ENV:Body> <ns1:capitalize xmlns:ns1="http://192.168.0.103:8888/file_manager/services/EchoCaps";> <inputString xsi:type="xsd:string">Input from C++ Client</inputString> </ns1:capitalize> </SOAP-ENV:Body> </SOAP-ENV:Envelope> ==== Response ==== HTTP/1.1 200 OK Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Fri, 28 May 2004 20:20:42 GMT Server: Apache-Coyote/1.1 20d <?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> <ns1:capitalizeResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:ns1="http://192.168.0.103:8888/file_manager/services/EchoCaps";> <EchoCaps xsi:type="xsd:string">INPUT FROM C++ CLIENT</EchoCaps> </ns1:capitalizeResponse> </soapenv:Body> </soapenv:Envelope> 0 ============== On Friday 28 May 2004 12:26 pm, Ben Souther wrote: > Hello, > > I've used the WSDL2Ws tool that ships with Axis C++ to create a simple > client for a java webservice running on axis/tomcat.
