Wso2 axis2_http_服务器无法加载服务库

我正在尝试让一个简单的hello world web服务工作。我使用WSDL2CPP从wsdl文件生成服务代码。这将生成并显示在的服务列表中

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：

[Tue Aug 27 09:50:31 2013] [debug] http_worker.c(186) Client HTTP version HTTP/1.1

关注范围包括：

这看起来像是WSO C++代码和Axserver服务器C代码之间的名字。有什么想法吗？

可能是您忘了链接WSO2 WSF/C++本身

尝试重新编译您的服务，将

-lwso2\u wsf

添加到LDFLAGS中。

我正在使用：

g++-g-shared-olibHello\u service.so-I$WSFCPP\u HOME/include-I.-I$WSFCPP\u HOME/include/axis2-1.6.0-I$WSFCPP\u HOME/include/axis2-1.6.0/platforms-L$WSFCPP\u HOME/lib-util\laxis2\laxis2\u引擎-laxis2_解析器\-lpthread \-laxis2_http_发送方\-laxis2_http_接收方\-lguththila \-lws2_wsf\*.cpp

因此，我认为它构建正确。这很奇怪，因为服务器一开始加载服务很好。

c++filt\u ZN7wso2wsf11Environment6getEnvEv

给出了

wso2wsf:：Environment:：getEnv（）

——它应该在

libwso2\u wsf.so

。尝试通过启动

nm/path/to/libwso2_wsf.so | grep(grep)zn7wso2wsf11environment6getenev

来检查它，并将结果写入此处。00017750 T(u zn7wso2wsf11environment6getenvewell，符号在那里，此库正在导出该符号（符号类型为“T”）。确保您从与服务链接相同的库开始。我的意思是可以有两个不同的库：一个在LD_LIBRARY_路径中（不包含该符号），另一个在

$WSFCPP_HOME/lib

中。还有一个好处是在链接服务时禁用未定义的符号：将

-Wl，--no undefined

添加到

LDFLAGS

以查看链接时缺少哪些符号。我现在认为我是个白痴，没有在运行服务器的shell中设置LD\u LIBRARY\u路径。掌心。我得再试一次monday@paul-奥格尔维：嗨，保罗，我找到了这个的复制品，所以把它合上了。请考虑这一更新。参见@ SJSAM。
