Problem in putting the classpath

Question

HI!
I have a serious problem!
I'm trying to create a connection using the antinav jdbc driver type 3 for WindowsXP and Access 2000.
I also have installed JDK1.4.2 version and I use JCreatorLE environment.
I followed the instructions of README.text but nothing works!
I'll tell you what I did and please reply to me for a solution!
First of all I run the Setup.exe contained in package AccessOnNT.zip
After that I run the InstallAtinavService program from the StartMenu and I started the Service.
I copied JdbcClasses.jar to a directory c:\AtinavDriver\classes\ and after that I went to ControlPanel-->System-->Environment and put as Variable=CLASSPATH and as a value=c:\AtinavDriver\classes\JdbcClasses.jar
I also put the classpath to JCreatorLE. I went to Configure-->Options-->JDK Profiles and I added the package c:\AtinavDriver\classes\JdbcClasses.jar
The code I wrote is the following:
import java.sql.*;
import java.util.*;
public class test{
public static void main(String[] arguments){
try{
Class.forName("acs.jdbc.Driver");
} catch(Exception eDriver) {
System.out.println("driver " +eDriver);
String url="jdbc:atinav:localhost:7227:c:\\databases\\my movies.mdb";
String username="Admin";
String password=" ";
try {
Connection conn=DriverManager.getConnection(url,username,password);
Statement st=conn.createStatement();
ResultSet rec=st.executeQuery("SELECT title,category"+"FROM my movies.mdb Contacts"+
"WHERE"+"ORDER BY title");
while (rec.next()) {
System.out.println(rec.getString("title")+"\n"+rec.getString("category"));
st.close();
}catch (Exception eConnection) {
System.out.println("Connection " + eConnection);
When I execute I get this message :
driver java.lang.ClassNotFoundException: acs.jdbc.Driver
Connection java.sql.SQLException: No suitable driver
Press any key to continue...
Please tell me what I did wrong as soon as posible!
Thank you!

Looks like your JCreator CLASSPATH is okay. If it wasn't, you would have gotten a ClassNotFoundException for the JDBC driver. Looks like you got past that.
Your exception says "Connection java.sql.SQLException: No suitable driver". That usually means that your database connection URL is incorrect.
String url="jdbc:atinav:localhost:7227:c:\\databases\\my movies.mdb";This does not look correct at all.
I'm unfamilar with this Antinav type III driver you're using. Why isn't the JDBC-ODBC bridge driver sufficient? Did you have to pay for this? What made you think it was necessary?
If you use the bridge driver, you can connect using this code:
import java.sql.*;
import java.util.*;
public class AccessConnection
    public static void main(String [] args)
        try
            AccessConnection ac = new AccessConnection();
            if (args.length > 0)
                ac.findMoviedByCategory(args[0]);
            else
                System.out.println("Usage: java AccessConnection <category>");
        catch (Exception e)
            e.printStackTrace();
    public void findAllMoviesByCategory(final String category) throws SQLException, ClassNotFoundException
        Connection conn = null;
        PreparedStatement st = null;
        ResultSet rs = null;
        try
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String url      = "jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb)};DBQ=c:\\databases\\my movies.mdb";
            String username = "admin";
            String password =   "";
            conn        = DriverManager.getConnection(url,username,password);
            String sql  = "SELECT title,category FROM movies WHERE category = ? ORDER BY title";
            st          = conn.prepareStatement(sql);
            st.setString(1, category);
            rs = st.executeQuery();
            while (rs.next())
                System.out.println(rs.getString("title") + " " + rs.getString("category"));
        finally
            try { if (rs != null) rs.close(); } catch (SQLException ignore) {}
            try { if (st != null) st.close(); } catch (SQLException ignore) {}
            try { if (conn != null) conn.close(); } catch (SQLException ignore) {}
}There were other problems (e.g., your SQL query wasn't correct - no WHERE value.)
