MYSql JSP connection

Hi!
I am trying to conect to MySql database form a jsp page, but I get error. I am using the following:
1. MySql dababase installed in C:/mysql
2. Tomcat installed in c:/tomcat
3. JDBC driver "mm.mysql-2.0.14-bin.jar" installed in c:\tomcat\lib
Here is my code:
<%@ page import="java.sql.*" %>
<%
String connectionURL = "jdbc:mysql://localhost:3306/gixpro1?user=username&password=pwd";
Connection connection = null;
Statement statement = null;
ResultSet rs = null;
%>
<html><body>
<%
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
connection = DriverManager.getConnection(connectionURL, "", "");
statement = connection.createStatement();
rs = statement.executeQuery("SELECT * FROM gixpro1");
while (rs.next()) {
out.println(rs.getString("name")+"<br>");
rs.close();
%>
</body></html>
Here is my error:

Not sure which Tomcat your using, but if your using Tomcat 4.1.9 you should put it in either c:/tomcat/shared/lib or c:/tomcat/common/lib (the c:/tomcat/lib is no more in 4.1.9 as far as I know).
If your in Tomcat 4.0.4, you should be okay where your jar is (c:/tomcat/lib); but for kicks you could try moving it to c:/tomcat/common/lib.
Of course; you could place it in your c:/j2sdk.../jre/lib/ext directory and c:/program files/java/jre/lib/ext and that would solve the problem also.

Java Connector via MySQL [ Cannot Connect ]

I downloaded the MySql connector and extracted the connector and placed it at this directory,
C:\Program Files\Java\jdk1.5.0_06\jre\lib\ext
I also set the classpath as such by adding
ClassPath = .;C:\Program Files\Java\jdk1.5.0_06\jre\lib\ext\mysql-connector-java-3.1.12-bin.jar.Actually , I followed the tutorial at
http://www.stardeveloper.com/articles/display.html?article=2003090201&page=4.
I then executed this program below.
import java.sql.*;
public class Connect {
public static void main(String args[]) {
    Connection con = null;
    try {
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     con = DriverManager.getConnection("jdbc:mysql:///enron", "root", "horizon");
      if(!con.isClosed())
        System.out.println("Successfully connected to MySQL server...");
    } catch(Exception e) {
      System.err.println("Captured Exception: " + e.getMessage());
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
However i was unable to connect..This is wat happened as below..

Any Help watsoever is greatly appreciated.
Thanks in advance.

Hi thanks for the reply.
Although , I am though a bit baffled by your reply.
Where is it that you want me to add the URL.Not add the URL - change the one you have. Read the docs for the connector and follow that.
And where else should i place that jar file.I put it in my CLASSPATH, close to where the source for my project is. (That means not in one place, but several places. I duplicate the JAR file for every app that needs it.)
Cos I follow the tutorial at...
http://www.stardeveloper.com/articles/display.html?art
icle=2003090201&page=4.
Unless You are saying that the above site is wrong..
If thats the case, can you point out another
alternative site which can guide me along .No time to read that site, nor do I have the interest.
The Sun Java tutorial is sufficient for using JDBC. As far as how you package and deploy apps, that's another matter. You should be using the class name and URL that your JDBC driver docs suggest.

MySQL gateway connection

Looks like plenty of folks here have similar problems getting the dg4odbc gateway working for MySQL. Hope someone that's tackled this can help me out.
Our configuration is such that we have our gateway machine separate from our Oracle database, and the MySQL machine is yet another server. We have installed and configured the gateway along with the unixODBC gateway and the MySQL connector. Running ./isql from the gateway successfully connects to the MySQL database and returns rows from specified tables.
Our difficulty is with setting up the listener.ora (on the gateway) and tnsnames.ora (on the Oracle host). Here are the contents of those files:
listenter.ora:
SID_LIST_LISTENER =
    (SID_DESC =
      (PROGRAM = dg4odbc)
      (ORACLE_HOME=/db01/app/oracle/product/gateways)
      (SID_NAME = myodbc3)
      (ENVS=LD_LIBRARY_PATH=/opt/unixODBC/lib:/opt/mysql/myodbc5/lib:/usr/local/lib:/db01/app/oracle/product/gateways/lib)
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = gw_host)(PORT = 1521))
)tnsnames.ora:
dg4odbc =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = gw_host)(PORT = 1521))
    (CONNECT_DATA = (SID= myodbc3))
    (HS=OK)
)Listener status on the gateway is:

I logged into sqlplus and create a public database link:

P.S. tnsping from the Oracle database to the gateway gives this:

Maybe it is sufficient to get the part where the libodbc.so library is loaded, so check where you'll find it in the strace file and provide this info until the error is visible in the traceHopefully this is what you wanted from truss.

Mysql not connecting

Hi all
I have downloaded the J connector, both 5.0.8 and 5.1.13 but they both gives me problems.
if i try:

Error MySQL #2002 connection could not be made etc from phpMyAdmin

Error MySQL #2002 connection could not be made etc from phpMyAdmin
I am just seting up Adobe Flash Builder 4.5 for PHP, Zend Server, MySQL and phpMyAdmin.
On attempting The Tutorial Build your first Mobile PHP project I am getting this error.
Can anybody help please ?

Just thought I would add that I did every test the help files suggest, no firewall etc.
Strange thing is that after the majority downloaded I had about 55 apps left that could not be updated because of the network connection that could not be made, I downloaded them manually instead of clicking 'yes please do download them all'.
I still came across a few that gave me the msg that an connection could not be made but when I skipped them and came back later to try again it did download. Took some time but I now have them all up to date.
Now see if I can sync the iPhone and iPad.
I run the latest iTunes 10.4.1 (10) and 10.6.8, have not updated to Lion yet.
cheers,
Christine

Mysql.sock - connection error (code 2002)

Performed a clean install of SL Server.
Enabled Web and MySQL services.
When using GUI (SequelPro of MySQL GUI Tools) I get a mysql.sock connection error.
"Could not connect to MySQL instance at localhost. Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) (code 2002)"
The database location of MySQL is /var/mysql. Thus a reference to /tmp/mysql.sock is obviously wrong.
The file /var/mysql/mysql.sock does exist but apparently no reference is made to this file.
Q: How to make a reference to the correct socket file,
Coen

It looks looks like the Sequel Pro app is guessing incorrectly that the mysql.sock is in /tmp. If that's the problem, you should be able to fix it by going to Sequel Pro's Connection panel and entering the correct path, which is /var/mysql/mysql.sock.

MySQL -- JDBC Connection help !!!

Hi everybody...Well I have MySQL Server and Java, I get the JDBC and tried this:
import java.sql.*;
public class JdbcE {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql://localhost/test", "user", "pass");
if(!con.isClosed())
System.out.println("Successfully connected to MySQL server...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}
And with that code all works fine...but when I change the Host from LOCALHOST to [ROUTER IP] like this:
con = DriverManager.getConnection("jdbc:mysql://182.185.145.12/test", "user", "pass");
I got this exception:
Exception: Communications link failure due to underlying exception:

I don't know how to solve it...
I have a 2wire 1700HG router, maybe it would be a problem of the firewall can anyone help me to solve this problem??

Well I sorry...I am very new in this kind of things...I just know that I have a 2wire 1700HG, I have installed MySQL Server, Java and mysql-connector-java...
When I try this in the connection statement:
con = DriverManager.getConnection("jdbc:mysql://localhost/test", "user", "test");
Everything works fine...but when I try this to connect from a remote PC
con = DriverManager.getConnection("jdbc:mysql://189.145.185.182/test", "user", "test");
This error comes out on screen:

Please help setting up Mysql ASP connection on a Mac DW8

Dear All
I have posted previously but I still have not solved this
problem, and really need anybody with a mac DW setup to give some
advice. I have spoken to Adobe and trawled the net looking for a
solution to getting ASP and DW working on a mac. I know I need a
windows machine and a local network which I have. I have a real
issue making a database connection from within dreamweaver.
Please help anybody with experience.
Many thanks in advance
Graham

I don't know how you can define the MySQL database connection
string in DW,
because I only use DW for layout purposes (HTML + CSS). But I
have an
ASP/VBscript site running against a MySQL database, and it
successfully uses
the following connection string:
"DRIVER={MySQL ODBC 3.51 Driver};SERVER=" & myDBhost
& ";DATABASE=" &
myDBname & ";USER=" & myDBuserid & ";PASSWORD="
& myDBpassword &
";OPTION=3;"
Hope this helps.

Why my MySQL JDBC Connect fail??

Dear friends:
I have following code:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class JdbcExample2 {
public static void main(String args[]) {
    Connection con = null;
    try {
      Class.forName("com.mysql.jdbc.Driver").newInstance();
      //jdbc:mysql://host_name:port/dbname
//     con = DriverManager.getConnection("jdbc:MySQL:///test","admin", "admin");
      con = DriverManager.getConnection("jdbc:MySQL://localhost:3306/test","admin", "admin");
      if(!con.isClosed())
        System.out.println("Successfully connected to " +
          "MySQL server using TCP/IP...");
    } catch(Exception e) {
      System.err.println("Exception: " + e.getMessage());
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
}But when I run , I got following error:
Exception: com.mysql.jdbc.Driver
My question is:
[1]. when I connect to MySQL Server through mySQL Client, I got
Enter password: *****
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 18 to server version: 4.1.21-community-nt
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
how Can I determine MySQL Server name?? I forgot when I install, maybe MySQL is my SQL Server name
[2]. Do I need to creat a user DSN name or System DSN name for MySQL Server?? which one is best??
How to do it??
[3]. How to make above simple JDBC program runnable??
Thanks
sunny

MySQL database connection from Custom JSP

I am trying to connect MySQL database from my custom JSP. I am getting following error which says that the connector JAR (mysql-connector-java-5.1.7) is not in CLASS PATH.
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Where should I need to add to get by custom JSP during run time of BPM Studio or Workspace?
I have tried in adding to External resources. But didn't work that way. even I tried adding to "lib" folder in resource view.
My Custom JSP code:_
<%@ page language="java" import="java.sql.*" %>
<html>
<head></head>
<body>
<%
System.out.println("MySQL Connect Example.");
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "aboo";
String driver = "com.mysql.jdbc.Driver";
String userName = "monty";
String password = "some_pass";
try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
System.out.println("Connected to the database");
String query = "Select * FROM employeee";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query);
while (rs.next()) {
System.out.println(rs.getInt(1));
System.out.println(rs.getString(2));
conn.close();
System.out.println("Disconnected from database");
