Salut,

You neither define tmp nor temp so its difficult to spot where the
actual problem
is. You should be able to do however:

> structure* jumboExt :: iXSGetData() {
>
       structure_var tmp = new structure();
 
>      tmp->length( 100 );
>      for( int i=0; i < 100; i++ ) {
>           tmp[i] = i;
>      };
> 
       return tmp._retn();
> };

>      structure     *data;
To be CORBA-compliant you'd rather write

       structure_var data;

>      data = handler->iXSGetData();
> 
> } catch ( CORBA :: Exception & ) {
> 
>      cout << "Exception";          // This exception was thrown
> 
> };

Probably due to some memory management problem in the server
because the sequence wasn't allocated properly. The book on
'Advanced CORBA programming with C++' by Henning/Vinoskit has
a good explaination of the memory management issues when using CORBA.
