when I run the server in the ice demo Ice\plugin ,I find initialize() function which is in the helloplugin34d.dll ,is called but don't know when it is called.

helloplugin code as follow:
///////////////////////////////////////////////
class HelloPluginI : public Ice::Plugin
{
public:

HelloPluginI(const Ice::CommunicatorPtr& communicator) :
_communicator(communicator)
{cout<<"通信器初始化!"<<endl;
}

void
initialize()
{
cout<<"hello适配器初始化!"<<endl;
Ice::ObjectAdapterPtr adapter = _communicator->createObjectAdapter("Hello");
adapter->add(new HelloI, _communicator->stringToIdentity("hello"));
adapter->activate();
}//为什么会调用这个函数?

void
destroy()
{
cout<<"销毁初始化!"<<endl;
}

private:

Ice::CommunicatorPtr _communicator;
};

};

extern "C"
{

ICE_DECLSPEC_EXPORT ::Ice::Plugin*
createHello(const Ice::CommunicatorPtr& communicator, const string& name, const Ice::StringSeq& args)
{
return new HelloPluginI(communicator);
}

}
/////////////////////////////////////////////////////



the server code as follow:

////////////////////////////////////////////////////
#include <Ice/Ice.h>

using namespace std;

class PluginServer : public Ice::Application
{
public:

virtual int
run(int argc, char* argv[])
{
if(argc > 1)
{
cerr << appName() << ": too many arguments" << endl;
return EXIT_FAILURE;
}

communicator()->waitForShutdown();
return EXIT_SUCCESS;
}
};

int
main(int argc, char* argv[])
{
PluginServer app;
return app.main(argc, argv, "config.server");
}
//////////////////////////////////////////////////////



the config.server code as follow :
//////////////////////////////////////////////////////
#
# Warn about connection exceptions
#
Ice.Warn.Connections=1

#
# Network Tracing
#
# 0 = no network tracing
# 1 = trace connection establishment and closure
# 2 = like 1, but more detailed
# 3 = like 2, but also trace data transfer
#
Ice.Trace.Network=1

#
# Protocol Tracing
#
# 0 = no protocol tracing
# 1 = trace protocol messages
#
#Ice.Trace.Protocol=1

#
# Logger Plugin Configuration
#
Ice.Plugin.Logger=LoggerPlugin:createLogger

#
# Hello Plugin Configuration
#
Ice.Plugin.Hello=HelloPlugin:createHello
Hello.Endpoints=tcp -p 10000
//////////////////////////////////////////



I trace the sever runing ,when the code run
///////////////////////////////////////////
class PluginServer : public Ice::Application
{
public:

virtual int
run(int argc, char* argv[])

//////////////////////////////////////////

    Hi,

    The plugin initialize method is called when the communicator is initialized (which occurs is your case when you call the main method on the Ice.Application object). See here for more information on the Plugin API.

    Cheers,
    Benoit.
