Getting [SQLITE_BUSY] database file is locked with select statements

Question

If I run multiple threads against my web app I get:

java.sql.SQLException: [SQLITE_BUSY]  The database file is locked (database is locked)
    at org.sqlite.         


        

Answer 1

There should be only ONE connection with your application. you can use this to ensure.

public class SqliteHelper {
private static Connection c = null;
public static Connection getConn() throws Exception {
    if(c == null){
    Class.forName("org.sqlite.JDBC");
    c = DriverManager.getConnection("jdbc:sqlite:D:/test.db");
    }
    return c;
    }
}
