I want my applet (it runs in AppletViewer -> jdk 1.1) to
get the ResultSet which was made on the server. I'm using CORBA (VisiGenic 2.5). How should my .idl file look like (returning types of methods) and how should be appropriate methods in server class and in client class declared?

ResultSet is Java interface. At the moment I convert the results
to the CORBA structure-sequence. Then they're pushed to the client. I want to skip the converting part.

Probably the simplest approach is to use Visibroker's java2idl compiler to create an IDL file automatically from your Java interface. You can then use the TIE method to associate a CORBA object with a corresponding Java implementation.  This requires the client to obtain the information in your ResultSet via method calls.

You may be able to do even better, perfomance-wise, by using VisiBroker's Caffiene product, which allows you to pass Java objects by value; this is not currently standard CORBA, but it works - and the OMG is working on a standard way to do exactly this (expect the standard to be pretty close to Caffiene).
