Hello All,
I recently downloaded a ODBC driver (17th Aug 2001 release) called LinkBook for QuickBooks. The driver when used with JAVA(JDK1.1.8 ) ie accessed using JDBC-ODBC Bridge works fine and allows me to acess data stored inside .QBW files of QuickBooks.

But when I try to run the same code using JDK1.3,it throws me an exception saying

"Exception in thread "main" java.sql.SQLException: The result set type is not supported.
at sun.jdbc.odbc.JdbcOdbcStatement.initialize(JdbcOdbcStatement.java:154)
at sun.jdbc.odbc.JdbcOdbcConnection.createStatement(JdbcOdbcConnection.java:420)
at sun.jdbc.odbc.JdbcOdbcConnection.createStatement(JdbcOdbcConnection.java:394)
at checkQuickBook.main(checkQuickBook.java:16)"
If any one has accessed QuickBooks .QBW files by any means using JAVA,I would like to hear from u.Kindly help me,its urgent.

here is the code that I have written.Kindly help me solve this problem.

CODE
----------------------------------------------------------------------------------------------------------------------------------
import java.sql.*;

public class checkQuickBook
{
public static void main(String args[]) throws Exception
{
String url = "jdbc dbc:myfirstlinktoquickbooks";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection(url,"","");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM Budgets");//Budgets is a table in default DB that comes with QuickBooks
while(rs.next())
{
System.out.println(rs.getString(1));
}
}
}
Hi,
In your question u have mentioned that there is a digital certificate for each client.Can u tell me how were u able to authenticate the client from server (ie) how did u send the certificate to server for verification when the server demands for it(SSL3.0 where the server demands client authentication).we r also working on a similar project and will be greatfull if u can help us out.
Thank You

Hi everyone.
I have recently started working on SSL.All I did was configured my Tomcat4.0 to handle SSL by generating a certificate according to its specification.
But when I try to access "Https" through an application whose source code, I have given below I get "javax.net.ssl.SSLException: untrusted server cert chain"
Exception.Can any one please help me find a solution to this problem.
The code is
public class URLReader
{
public static void main(String[] args) throws Exception
{
String inputLine;
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
URL verisign = new URL("https://localhost:8443/");
BufferedReader in = new BufferedReader(new InputStreamReader(verisign.openStream()));
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
}
}
And also can any one help me to set up the Server ID that verisign gives free on trial basis on Tomcat4.0.
Expecting replies.
Bye
Sunil
