cpp classes from axis2c service
Hello list,
I want to access cpp classes from a axis2c service. Therefore I generated a simple service adding two numbers. I compiled the skeleton file with g++ and all the rest of the files with gcc. After that everything is linked with g++.
The problem is when I want to access the service a always get a segmentation fault. For my opinion everything is wright - all .h have the extern C statement and so I think it is possible to link c and cpp together in one so file.
Have I made something? Or is it impossible to access cpp classes from the service? If it is possible, what have I made wrong? I'm using axis2c version 1.0.
Kind regards
Michael

Could you please send in your service code and the commands you used to
compile the service?
That would help us to figure out the problem.
Thanks,

Hello Rajiky
I'm not so familiar with c development and for my opinion it is not
possible to debug a remote service.
If it is how can I enable it? I already added some printf in the service
implementation. The first one is in the initialization of the service.
But these output are not visible - so I think the Segmentation fault
occurs when loading the so file.

Hello Michael,
I did the same thing but for the client side(i.e developed a c++ client
which uses the axis2/c libs), and it works fine for me, and I think your
case should be possible, may be you can enable debug options in compilation
and try to debug to figure out where it breaks.
