    I Am getting Socket error while using this code whereas this code is working fine on my localTomcat Server.

    <%@ page import = "java.io.*, java.util.*,java.net.URL,java.awt.*,java.lang.*,java.sql.*" %>
    <%@ page import="com.mysql.jdbc.Driver" %>
        ResultSet rs;
    	Statement stmt;
         try {
    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/petrofe","petro", "petro");
    	String sql = "SELECT * FROM sample";
    	stmt = conn.createStatement();
    	rs = stmt.executeQuery(sql);
    	while (rs.next())
                 // Do something with the Connection
             } catch (SQLException ex) {
                 // handle any errors
                 out.println("SQLException: " + ex.getMessage());
                 out.println("SQLState: " + ex.getSQLState());
                 out.println("VendorError: " + ex.getErrorCode());
             catch (ClassNotFoundException cnfex)
    		 	       out.println("SQLException: " + cnfex.getMessage());

    Please Help

    I am not a java programmer at all, but it appears that your getting a permission error. I would begin by making certain that your user/pass for mysql are working. Type the following from the command line:

    mysql -u petro -p

    You should be prompted for your password, if you get a successfull connection: mysql>
    you will have at least narrowed the problem down to a tomcat/jdbc problem, and not a mysql problem.

    If that doesn't work, hopefully someone with more java experience would be able to help.

    In /var/tomcat4/conf/catalina.policy

    add the following to the web application grant section

    permission java.net.SocketPermission "localhost:3306", "connect,resolve";
