DSNLess Connection to OracleDB v8.1.7

Question

Hi, I encounter problems in using DSNless approach to connect to Oracle DB. My program is using JDK1.1.8, Oracle DB version 8.1.7. Please help to identify the problem and provide solution to it.
Below is the code used and the error message
Trial A:
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
con = DriverManager.getConnection("jdbc:oracle:thin:@IP Address:port:Oracle_SID", uid, pwd);
Error --> java.sql.SQLException: Protocol violation
Trial B:
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
con = DriverManager.getConnection("jdbc:oracle:thin:@hostname:port:Oracle_SID", uid, pwd);
Error --> java.sql.SQLException: hostname
Trial C:
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
con = DriverManager.getConnection("jdbc:oracle:thin:uid/pwd@hostname:port:Oracle_SID");
Error --> java.sql.SQLException: hostname

Answer 1

Hi,
The "protocol violation' is message that is thrown when Oracle cant throw a more
specific message.
Please try following code, but before that please include classes12.zip in ur classpath. This file contains the oracle thin driver.
Connection connection = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@hostname:port:Oracle_SID"
connection = DriverManager.getConnection(url, "dbName", "password");
}catch (Exception e){
e.printStackTrace();
good luck ...san :-)
