Date: Mon, 31 Jul 2000 04:39:43 -0700 (PDT)
Message-ID: <20000731113943.29286.qmail@web4902.mail.yahoo.com> (raw)
Before, I can connect database both from applet or
servlet.But today, when I try to connect database from
applet or servlet, there was a problem.
By servlet the error message is : "Couldn't load DB
driver :null".
By applet, in the browser just appear "Connecting to
database ", and in the status bar is a message "Applet
myapplet org/postgresql/jdbc2/Resultset".
Help me please......
The SERVLET code :
import java.io.*;import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class myServlet extends HttpServlet
{
public void doGet(HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
Connection con = null;Statement stmt = null;
ResultSet rs = null;
res.setContentType("text/html");
PrintWriter out = res.getWriter();
try[
Class.forName("org.postgresql.Driver");
con =
DriverManager.getConnection("jdbc:postgresql:myDB",
"me", "pass");
stmt = con.createStatement();
rs = stmt.executeQuery("select k_id,
k_name, date
from myTable");
out.println("<HTML><HEAD><TITLE>KAMOKU</TITLE></HEAD>");
out.println("<BODY><FONT
COLOR='RED'><H3><BR>TEST
SERVLET & JDBC</H3><BR></FONT>");
out.println("SELECT id, name, date FROM
kamoku<BR><BR> ");
out.println("<UL>");
while(rs.next()){
out.println("<LI>" +
rs.getString("k_id")+" "+
rs.getString("k_name") + " " + rs.getDate("date"));
}
out.println("<UL>");
out.println("</BODY></HTML>");
}
catch(ClassNotFoundException e)
{
out.println("Couldn't load DB driver : " +
e.getMessage());
}
catch(SQLException e)
{
out.println("SQLException caught : " +
e.getMessage());
}
finally
{
try
{
if (con != null) con.close();
}
catch (SQLException ignored) { }
}
}
}
Thank you.
