I have the following problem trying to create a Connection object to handle the connection from a command line Java application and an Oracle database.
So I have a Main class that contains the main() method, this one:
import java.sql.*;
import oracle.jdbc.OracleDriver;
public class Main {
public static void main(String[] args) {
System.out.println("Hello World !!!");
String partitaIVA = args[0];
String nomePDF = args[1];
Connection conn = null;
Statement stmt = null;
try {
Class.forName ("oracle.jdbc.OracleDriver");
// Step 1: Allocate a database "Connection" object
conn = DriverManager.getConnection("jdbc:oracle:thin:@XXX.XXX.XXX.XXX:1521:eme1", "myUserName", "myPswd"); // Oracle DB
} catch(SQLException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
}
}
The problem is that when I try to perform this instruction:
conn = DriverManager.getConnection("jdbc:oracle:thin:@XXX.XXX.XXX.XXX:1521:eme1", "myUserName", "myPswd"); // Oracle DB
I obtain this exception:
java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-01882: timezone region not found

So, I remember that in some other applications that works with this DB it was necessary to set the timezone or something like this (but now I can't access to these applications).
So, how can I fix this issue? Can I set programmatically the timezone for my Connection?
Tnx
Write this before your connection attempt:
TimeZone timeZone = TimeZone.getTimeZone("yourTimeZone"); // e.g. "Europe/Rome"
TimeZone.setDefault(timeZone);
So the whole code would be:
try {
TimeZone timeZone = TimeZone.getTimeZone("yourTimeZone");
TimeZone.setDefault(timeZone);
Class.forName("oracle.jdbc.OracleDriver");
conn = DriverManager.getConnection("connStr", "myUserName", "myPswd");
...
If this does not work, the problem may be an invalid JDBC driver version.
