I have to create a SQLite database that I will ultimately have to insert lines of data from a parsed .csv file. The issue that I'm having is creating the SQLite database in the intellij idea. Using the code below I continue to get the "No suitable driver" error. I believe that I've added the classpath correctly by using Project Structure-> Modules-> Add then selecting my downloaded SQLite .jar file, which in this case is sqlite-jdbc-3.30.1 (1).jar
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.SQLException;
public class mint {
public static void createNewDatabase(String fileName) {
String url = "C:\\SQLite\\sqlite-jdbc-3.30.1 (1).jar" + fileName;
try {
Connection conn = DriverManager.getConnection(url);
if (conn != null) {
DatabaseMetaData meta = conn.getMetaData();
System.out.println("The driver name is " + meta.getDriverName());
System.out.println("A new database has been created.");
}
} catch (SQLException e) {
System.out.println(e.getMessage());
System.out.println("An error occurred while connecting MySQL database");
}
}
public static void main(String[] args) {
createNewDatabase("input-filename.db");
}
}
Screenshot of output
You need to read this tutorial - URL should be like this
String url = "jdbc:sqlite:C:/sqlite/" + fileName;

I have inserted my SQLite.db file inside of package named newpackage
Location of database file I inserted here isCollegeProject\src\operalogsapp\newpackage\SQLite.db
Now I want to get this database, so I want the correct format for inserting it to driver manager.
public class databaseConnection {
public static Connection con;
public static Connection getDBConnection(String username, String password, Integer portNumber, String serviceName){
try {
//Register the JDBC driver
System.out.println("before className");
Class.forName("org.sqlite.JDBC");
System.out.println(con==null);
System.out.println("Registered to the JDBC driver");
//Open the connection
if("V50700_HOTEL".equals(username) && "V50700_HOTEL".equals(password) && portNumber==1501 && "operal".equals(serviceName)){
con=DriverManager.getConnection("jdbc:sqlite:C:\\Users\\absasahu\\Documents\\db\\SQLite.db");
//inside the getConnection (above line) I want to get correct location of database to enter.
System.out.println("DriverManager connected to db");
}
} catch (ClassNotFoundException | SQLException ex) {
System.out.println("Exception : "+ex);
//Logger.getLogger(dbCoonectionCode.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println("DFHUDSBFSDF");
return con;
}
Any help will be appreciated.
"jdbc:sqlite:sqlite_database_file_path", in your case from your code:
"jdbc:sqlite:C:/Users/absasahu/Documents/db/SQLite.db"
Regarding your question using a relative path:
"jdbc:sqlite:SQLite.db"
See also the answers at Set path to a jdbc SQLite database, where it will be located

Never tried it but seems like OpenOffice uses HSQLDB database underneath in file mode. Looks like you can connect to this HSQLDB database directly: Java: Creating a JDBC Connection to OpenOffice.Org Databases.
