[omniORB] IDL modules

[Hamilton Temple]

Hello there,

I have been working with the following idl definition:

interface Add{
double add(in string a, in string b, in string c);
};

In the server I use the following instruction to activate the object id:

AddImpl * addImpl=new AddImpl();
PortableServer::ObjectId_var myObjID = myPOA->activate_object(addImpl);

I modified the idl as follows:

module Operations{
interface Add{
double add(in string a, in string b, in string c);
};
};

I defined the corresponding namespace Operations in the implementation, and
added the line "using namespace Operations;" at the beginning of the server
code.

Now compilation fails with the following errors:

server.cpp: In function 'int main(int, char**)':
server.cpp:64: error: no matching function for call to
'PortableServer::POA::activate_object(Operations::AddImpl*&)'
/usr/include/omniORB4/poa.h:552: note: candidates are: virtual
PortableServer::ObjectId*
PortableServer::POA::activate_object(PortableServer::ServantBase*)
server.cpp:67: error: no matching function for call to
'PortableServer::POA::servant_to_reference(Operations::AddImpl*&)'
/usr/include/omniORB4/poa.h:566: note: candidates are: virtual
CORBA::Object*
PortableServer::POA::servant_to_reference(PortableServer::ServantBase*)

Any hints would be much appreciated. Thank you,

Hamilton

How is your class AddImpl defined ?


S.

Stefan, thank you for your answer.

AddImpl is defined as follows:

#include <Add.hh>

namespace Operations{
class AddImpl: public POA_Add, public PortableServer::RefCountServantBase{
CORBA::ORB_var orb_;
PortableServer::POA_var poa_;

public:
AddImpl();
virtual PortableServer::POA_ptr _default_POA();
virtual double add(const char * a,const char * b,const char * c)
throw(CORBA::SystemException);
};
};

Without the namespacing this code compiled without any problems.

Hi,

I just realized of my mistake. The correct definition is:

#include <Add.hh>

namespace Operations{
class AddImpl: public POA_Operations::Add, public
PortableServer::RefCountServantBase{
CORBA::ORB_var orb_;
PortableServer::POA_var poa_;

public:
AddImpl();
virtual PortableServer::POA_ptr _default_POA();
virtual double add(const char * a,const char * b,const char * c)
throw(CORBA::SystemException);
};
};

I hope that this helps to other CORBA rookies :D

Regards,

Hamilton
