Okay. There's not much code, though. This is a trivial test of the
service, and all it does is print out the input to a log file, copy back
the input params as outputs and log them. The logged stuff looks ok:
Here's the code:
void HUB_TO_HUB::Hub_Request(xsd__string Value0, xsd__string Value1,
xsd__string Value2, xsd__string Value3, xsd__string Value4, xsd__string
Value5, xsd__string Value6, xsd__string Value7, AXIS_OUT_PARAM
xsd__string *OutValue0, AXIS_OUT_PARAM xsd__string *OutValue1,
AXIS_OUT_PARAM xsd__string *OutValue2, AXIS_OUT_PARAM xsd__string
*OutValue3, AXIS_OUT_PARAM xsd__string *OutValue4, AXIS_OUT_PARAM
xsd__string *OutValue5)
{
chartimestamp[100];
time_t clock;
struct tm *tm;
FILE*file;
file = fopen("/home/rob/hub2hub/server/log", "w+");
fprintf(file, "Input:\n"
" TO_TP=%s\n"
" FROM_TP=%s\n"
" TO_HUB=%s\n"
" FROM_HUB=%s\n"
" UID=%s\n"
" APIKEY=%s\n"
" ROUTING=%s\n"
" MESSAGE=%s\n",
Value0, Value1, Value2, Value3, Value4, Value5,
Value6, Value7);
// Pass back caller's UID.
*OutValue0 = Value4;
// Pass back caller's FROM_TP as TO_TP.
*OutValue1 = Value0;
// Pass our hub ID as FROM_TP
*OutValue2 = "ABCD-EFGH-IJKL-MNOP";
// Force status code of 0 (SUCCESS) for now
*OutValue3 = "0";
*OutValue4 = "SUCCESS";
// Send timestamp.
clock = time((time_t *) 0);
tm = localtime(&clock);
sprintf(timestamp, "%04d-%02d-%02d %02d-%02d-%02d",
tm->tm_year+1900, tm->tm_mon+1, tm->tm_mday,
tm->tm_hour, tm->tm_min, tm->tm_sec);
*OutValue5 = timestamp;
fprintf(file, "Output:\n"
" UID=%s\n"
" TO_TP=%s\n"
" FROM_TP=%s\n"
" STATUS=%s\n"
" STATUS_MSG=%s\n"
" TIMESTAMP=%s\n",
*OutValue0, *OutValue1, *OutValue2, *OutValue3,
*OutValue4, *OutValue5);
fclose(file);
}
RE: Newbie questions and some weird behavior
Looks to me as if there are serialization problems on the server side. I guess this is something to do with errors in the manipulation of the pointer data members of the class being serialized by server for response. One thing to figure out is to know whether the error is in generated code or in the user written code. Will have to generate the code and see. Thanks, Samisa...

I tried simple axis server with gdb, and was able to debug my server. It now is able to log its inputs and outputs, and they look basically right. But the client still gets null pointers for all of the results. Then I used tcpdump to look at the SOAP that was passed back and forth. I've included it below. It looks like the input is correct, but the response is screwed up. Instead of what I expect to get: etc. I'm getting: UID>UID> TO_TP>TO_TP> etc. Also, the data between the bad XML tags is garbage. Interestingly, I get binary garbage that grows by 4 bytes for each subsequent result 'string'. Anyway, progress. Here's the TCP dump of the SOAP: POST /axis/HUB_TO_HUB HTTP/11 Host: 172 1648 246:80 Content-Type: text/xml; charset=UTF-8 SOAPAction: "HUB_TO_HUB#Hub_Request" Content-Length: 571 http://schemas xmlsoap org/soap/envelope/" xmlns:xsd="http://3 org/2001/XMLSchema" xmlns:xsi="http://www w3 org/2001/XMLSchema-instance"> http://localhost/axis/HUB_TO_HUB";> A B C E F G HTTP/1 1 200 OK Date: Thu, 05 May 2005 18:26:37 GMT Server: Apache/2 0 46 (Red Hat) Content-Length: 689 Connection: close Content-Type: text/xml http://schemas xmlsoap org/soap/envelope/" xmlns:xsd="http://www w3 org/2001/XMLSchema" xmlns:xsi="http://www w3 org/2001/XMLSchema-instance"> http://localhost/axis/HUB_TO_HUB";> UID>UID> TO_TP>TO_TP> FROM_TP>FROM_TP> STATUS>&STATUS> STATUS_MSG>&STATUS_MSG> TIMESTAMP>.&...TIMESTAMP> > > > > > > Here's my server.wsdd entry: > > > > > description="TVB Hub-to-Hub Service"> > > > > > value="/usr/local/axiscpp_deploy/lib/libhub2hub.so" /> > > > > > > Here's the wsdl: > > > > > > >xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"; > >xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"; > >xmlns:s="http://www.w3.org/2001/XMLSchema"; > >xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"; > >xmlns:tns="http://localhost/axis/HUB_TO_HUB"; > >xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/"; > >xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"; > >targetNamespace="http://localhost/axis/HUB_TO_HUB"; > >xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";> > > > > > > > targetNamespace="http://localhost/axis/HUB_TO_HUB";> > > > > > > > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > > > > > > > > > >> type="tns:MSG_RECPT" /> > > > > > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > >> type="s:string" /> > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > http://schemas.xmlsoap.org/soap/http"; > > style="document" /> > > > >> style="document" /> > > > > > > > > > > > > > > > > > > > > > > > > http://localhost/axis/HUB_TO_HUB"; /> > > > > > > > >

Re: Newbie questions and some weird behavior
You could test this with simple axis server and debug the same on Linux with gdb. I have written a small help file to let you know how to get simple axis server up and running on Windows. I hope you could adopt this to Linux. I have it http://people.apache.org/~samisa/SimpleAxisServer_HOWTO.txt for the time being, till I check the rest of the docs and commit this to CVS. Will have a look at you wsdl and see if I could get it working. Please try simple axis server in the mean time. Thanks, Samisa...
