Subject RE: cpp client segfault...
Date Fri, 15 Apr 2005 01:47:09 GMT
Hi Hernan,

did you get a SEGV? I remember fixing a SEGV in getElementAsString
shortly after alpha. So it might worthwhile to try the 1.5 final.

I have no idea though why it should only happen inside the 4th call
to getElementAsString and not before. 

Carsten

Subject: cpp client segfault...



Hi there,

I'm getting a segfault trying to run my axis-c cpp client:

(gdb) backtrace
#0  0xb7580fe1 in axiscpp::SoapDeSerializer::getElementAsString () from /usr/pic1/axis-c-1-5-alpha-linux/lib/libaxiscpp_client.so.0
#1  0x0804ae79 in Axis_DeSerialize_tLevel (param=0x807f624, pIWSDZ=0x8056010) at tLevel.cpp:48

#3  0xb755dabe in axiscpp::Call::getCmplxArray () from /usr/pic1/axis-c-1-5-alpha-linux/lib/libaxiscpp_client.so.0

#5  0x08049221 in main () at LevelsServiceClient.cpp:14

>From looking at this trace, the segfault occurs in the following code 
generated by axis-c (I've highlighted tLevel.cpp:48):

int Axis_DeSerialize_tLevel(tLevel* param, IWrapperSoapDeSerializer* pIWSDZ)
{
     param->Id = pIWSDZ->getElementAsString( "Id",0);
     param->Version = pIWSDZ->getElementAsLong( "Version",0);
     param->ProdCode = pIWSDZ->getElementAsString( "ProdCode",0);
     param->SequenceName = pIWSDZ->getElementAsString( "SequenceName",0);
48-->param->ShotName = pIWSDZ->getElementAsString( "ShotName",0);
     param->LevelName = pIWSDZ->getElementAsString( "LevelName",0);
     param->FxProperty = pIWSDZ->getElementAsString( "FxProperty",0);
     param->Note = pIWSDZ->getElementAsString( "Note",0);
     param->LevelType = pIWSDZ->getElementAsString( "LevelType",0);
     param->IsInPicture = pIWSDZ->getElementAsBoolean( "IsInPicture",0);
     return pIWSDZ->getStatus();
}

The SOAP message axis-c is deserializing is an array of tLevel instances and the 
segfault occurs while deserializing the first item.

I've been staring at this for a while now and I can't find my error though I'm 
sure it's another WSDL idiosyncrasy I have yet to learn.  I appreciate any help 
you might be able to offer.  SOAP messages and WSDL included below.

I'm using axis-c 1-5 Alpha.  My Server is an Axis Java server.  My Java clients 
generated by Axis Java work fine with this same WSDL.  There were no errors in 
my local AxisClientLog, but I've included the trace that results from the above 
execution at the end of this message.

thanks in advance... Hernan
