RE: Newbie questions and some weird behavior
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.
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

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...

Anyway, at one point today (after restarting Apache, this went away), I would run my client repeatedly and get one of the following exceptions (wierdly, the exception would change without any changes to the code): Exception : Soap method is not allowed to invoke (I read in this list that this is caused by a missing SoapAction, but it's there in my wsdl and in the generated code) Exception : Requested service is not registerd at the server (I originally had CPP:RPC, which I figured was causing this - since my binding style is document, but I still got it sometimes) Exception : Soap content is not valid (your guess is as good as mine - I don't know yet if my soap content's any good) After restarting apache, the service seems to run. At least the client doesn't log any exceptions, but I get an empty response from the service (null pointers for all the return values). Not knowing how to debug the service, I tried having it open a file and log info there. But when I add code to my server to do that, I get the following exception on running my client: Exception : HTTPTransportException:Input streaming error while getting data Timed out waiting for HTTP header message (1). This exception occurs immediately, so I don't know how it could be a timeout condition. For yucks, I tried replacing the fopen and fprintf's with a simple sprintf to a character buffer and got the same exception. When I comment out all the logging code the service seems to 'work' again (with null return values). At least that gives some kind of indication that my server is indeed running. So, my main question is, how are you supposed to debug axiscpp services? Is the simple_axis_server thing supposed to facilitate this? If so, any instructions? Some other questions: 1. Even though I've got complex types as the inputs and outputs of my service, xwsdl2ws generates methods that take all of the fields from the complex types as individual parameters (rather than passing and returning a structure). When I changed my binding style to rpc, I got structure-based methods generated. Is that just 'the way it works', or can I control this? Is one kind of method better than the other (the struct way seems more self-documenting than having Value0..7 and OutValue0..5? 2. When I try to bring up ?wsdl URL's for my service or the axis 'Calculator' sample (http://localhost/axis/calculator?wsdl), Apache logs a segfault. Do I have to explicitly put the wsdl file somewhere (or point to it in axiscpp.conf or elsewhere)?

I have added this how to content for windows into the win install guide and commited this into cvs. Please see http://cvs.apache.org/viewcvs.cgi/*checkout*/ws-axis/c/docs/wininstall-guide.html#simpleaxis Plan to update the Linux guide as well.

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...
