How to set the timezone region for JDBC Connection and avoid the SqlException timezone region not found?

问题

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

    at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:560)
    at java.sql.DriverManager.getConnection(DriverManager.java:582)
    at java.sql.DriverManager.getConnection(DriverManager.java:185)
    at Main.main(Main.java:21)

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

回答1:

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.
