Hi
 
For my project i need to transfer a char array from the client (java
idl) to the server (omniORB). This message should have 121 elements.
Therefore I created following idl file:
 
#ifndef __ECHO_IDL__
#define __ECHO_IDL__
 
interface Echo {
  typedef sequence<char,121> msg;
  msg testConnection(in msg testConnection);
};
 
#endif
 
The problem is hat i do not know how I can write into these
sequenz(array)
I think that this line from the xxxSK.cpp is important form e but i am
not able to understand it :
Echo::msg* testConnection(const Echo::msg& testConnection);
 
In the echo example this line looks like that:
char* testConnection(const char* msg);
 
For this line in the example file the c code to save something in this
variable is easy to understand
virtual char* incomingMsg(const char* mesg);
 
I can use msg in all my methods and i am able to return a string: return
CORBA::string_dup("Hier ist die Funktion testConnection");
 
I do not understand this with the created sequence in the idl file. How
can I access testConnection ????
 
 
Thanks Christian
