java.sql.SQLException: Io exception: Got minus one from a read call during JDBC connection with oracle

Question

Hi I am new to java when I tried to connect oracle with my java sample code I got the above exception

My Code is

import java.sql.*;
import java.io.IO         


        

Answer 1

solution 1 :

I think this exception is due to operating system internal environment problem.

I have got same problem with type 4 driver. But type 1 driver not giving this exception. So that currently I'm using type 1 driver.

Check port number, sid at tnsnames.ora

C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN\SAMPLE\tnsnames.ora

solution 2 :

install vmware on your computer, install OS, then program will work with type 4 driver.
