Hello ! I can connect to Oracle 8.1.6. server with this methods (from a simple class). DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); Connection conn = DriverManager.getConnection ("jdbc racle:thin:@qwert:asdfg:yxcvb", "scott", "tiger"); But if I try to do this from a servlet, I get the "no more data to read from socket" exception. (from the getConnection method) What is the problem ? Thanks.
