axis2_http_server fails to load service library

问题

I am trying to get a simple hello world web service working. I used WSDL2CPP to generate the service code from my wsdl file. This builds and shows up in service list at localhost:8080/axis2/services

Now, I have created a simple client to access the service. When I try to do a request to the web service, I see the following in my axis2.log:

The line of interest being:

This looks like some name mangling shenanigans between the WSO C++ code and the axis server's C code. Any ideas?

回答1:

Possibly you forgot to link against WSO2 WSF/C++ itself.

Try to recompiling your service adding -lwso2_wsf to LDFLAGS.
