Re: Segmentation fault when calling webservice
I've looked twice on my svc_skeleton_ops_var it seems ok, but I've found
how to reproduce the bug. It's a linker problem.
If I take the echo example and I try to compile it with an external libs
(-l option of gcc) even if I dont modify the echo service code, the server
crashes.
My LD_LIBRARY_PATH seems ok so, I've tried to put a link to my lib in
/usr/lib, it crashes again. It seems that there's a problem in the axis
lib loader.

Looking at the trace, most probably, this is to do with the init method
of your service implementation.
Could you please check the code where the svc_skeleton_ops are
initialized. It would help to see either the code or the WSDL that you
are using, if you have no concerns sending it to the list.
Thanks,
Samisa...

Problem with Complex Objects in AxisCPP Engine!!
I am facing a very serious problem with AxisCPP. The problem is a show-stopper for me. Here I explain: I am trying to deploy a web-service for ALE(application level events) as per the EPC Global standards. WSDL file has been taken from the EPC Global Standard web-site. The services are deployed properly. The Client sends an XML file, which axis server receives and deserializes into Objects named as ECSpecs ( It's a complex type object). But the Values in the ECSpec complex object are not proper. Example: The XML file sent by Client is: ?xml version=1.0 encoding=UTF-8 ? - ale:ECSpec xmlns:ale=urn:epcglobal:ale:xsd:1 xmlns:epcglobal=urn:epcglobal:xsd:1 xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=urn:epcglobal:ale:xsd:1 Ale.xsd schemaVersion=1.0 creationDate=2003-08-06T10:54:06.444-05:00 - logicalReaders logicalReaderdock_1a/logicalReader logicalReaderdock_1b/logicalReader /logicalReaders - boundarySpec startTriggerhttp://sample.com/trigger1/startTrigger repeatPeriod unit=MS2/repeatPeriod stopTriggerhttp://sample.com/trigger2/stopTrigger duration unit=MS3000/duration /boundarySpec - reportSpecs - reportSpec reportName=report1 reportSet set=CURRENT / output includeTag=true / /reportSpec - reportSpec reportName=report2 reportSet set=ADDITIONS / output includeCount=true / /reportSpec - reportSpec reportName=report3 reportSet set=DELETIONS / - groupSpec patternurn:epc:pat:sgtin-64:X.X.X.*/pattern /groupSpec output includeCount=true / /reportSpec /reportSpecs /ale:ECSpec When I try to access startTrigger etc, values the simple_axis_server dumps. Also, the repeatPeriod which is defined as xsd__long and should have a value 2000 is getting a value 275638678 I am using Xerces 2.2 and axiscpp 1.4. I guess it's a problem either with the XML Parser or Desrialization function. Can any one (Samisa, or any one) help me in this regard. Is it a problem with deep copy not being done in engine Awaiting your response.

[AXIS2C]: How to implement business logic in C++?
Hi Group,
Because all my business logics are implemented in C++, so I am trying to
implement the hello_svc.c in C++.
Here is what I did:
1. Added the explicit cast to cast void* to axis2_svc_skeleton_t*
axis2_svc_skeleton_t *svc_skeleton = NULL;
svc_skeleton = (axis2_svc_skeleton_t *)AXIS2_MALLOC(env-allocator,
sizeof(axis2_svc_skeleton_t));
2. Added the
#ifdef __cplusplus
extern C
{
#endif
and
#ifdef __cplusplus
}
#endif
at the beginning and the end of the hello_svc.cpp file.
3. compile it using g++ (with the same argument as with gcc)
4. copy the libhello.so to the axis2c hello service.
5. Invoide the hello client
then I got the Segmentation fault at the Invoke the handler context_handler
within the phase PostDispatch phase.
what did I do wrong? is it possible to implement the service skeleton code
in C++?
Thanks!!!

I think it is possible, in order to determine what has happened in your case we need some more details. 1. Are you sure about your service.xml ? What is the directory name that you use to put your service? 2. Can you provide us your axis2.log , Please make sure to run server in debug mode. 3. It would be great if you could send us gdb backtrace. thanks, Dinesh -- Dinesh Premalal http://xydinesh.wordpress.com GPG ID : A255955C GPG Key Finger Print : C481 E5D4 C27E DC34 9257 0229 4F44 266E A255 955C - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [AXIS2C]: How to implement business logic in C++?
Hi Dinesh, Thank you very much for the reply. I just realized that I didn't run the axis2_http_server with the correct permission, which caused the error I mentioned above. and no log files been written because of the lack of permission. Now it runs fine. :) Thanks.

Hi Yang and Dinesh, I don't think that the axis2_http_server should seg fault on a permissions issue. When I try to run the server without write permissions for log file, it instead is written to the standard output. I guess that this _might_ possibly be a bug. If you could please provide more details on how the seg fault could be recreated. -Dumindu. Now it runs fine. :) Thanks.
