axis2_http_server 加载服务库失败 [英] axis2_http_server fails to load service library

问题描述

我正在尝试让一个简单的 hello world web 服务正常工作.我使用 WSDL2CPP 从我的 wsdl 文件生成服务代码.这建立并显示在服务列表中localhost:8080/axis2/services

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

现在，我创建了一个简单的客户端来访问该服务.当我尝试向 Web 服务发出请求时，我在 axis2.log 中看到以下内容:

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:

感兴趣的线是:

这看起来像是 WSO C++ 代码和轴服务器的 C 代码之间的一些名称修改恶作剧.有什么想法吗?

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

推荐答案

可能你忘记链接 WSO2 WSF/C++ 本身了.

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

尝试重新编译您的服务，将 -lwso2_wsf 添加到 LDFLAGS.

Try to recompiling your service adding -lwso2_wsf to LDFLAGS.
