I want to connect to Oracle database via jdbc using ojdbc6 driver.
I have Oracle 10g in virtual machine, and Oracle 8i at work. I'm trying to create a java application that allows me to connect to the database and execute some SQL statement.
With Oracle 10g everything is fine, but with oracle 8i (8.1.7) i get this error
java.lang.ArrayIndexOutOfBoundsException: 4

And this line of the stacktrace (jdbcon is my class name)
at jdbcon$4.actionPerformed(jdbcon.java:235)
Take me to this line of code
con=DriverManager.getConnection("jdbc:oracle:thin:@"+adresse+":"+port+":"+bd,user,pass);
The source code
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
con=DriverManager.getConnection("jdbc:oracle:thin:@"+adresse+":"+port+":"+bd,user,pass);
if(con.isValid(10))
//System.out.println("Connexion réussie");
JOptionPane.showMessageDialog(null, "Connexion réussie");
Note
when i use a wrong SID it gives me this error :
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
This means that the host,Port are okay. And when i use the right SID i get the previous error .
This problem is only with oracle 8i.
Oracle version 8 is not supported by ojdbc6 and ojdbc5 drivers (these are for later version of oracle) , to connect you need:
classes12.zip drivers that can be downloaded from Oracle8i JDBC Drivers
