Jdbc mysql error

Hi,
Everything is set up and running on Redhat7.1. Version 1.3.1 of jdk is
installed and tomcat version 3.2.1.
I also installed the mod_jserv module and started serving jsp pages
which worked perfectly.
I then downloaded the mysql jdbc drivers from the mysql site and
installed them and set the classpath to
correct path in /etc/profile. I get the following error when connecting
to the mysql database:

Heres the code that i used.

//try {

Connection Conn =

Statement Stmt = Conn.createStatement();
String SQL="SELECT * from user";
ResultSet RS = Stmt.executeQuery(SQL);
while (RS.next()) {
System.out.println(RS.getString(1));
// Clean up after ourselves
RS.close();
Stmt.close();
Conn.close();
//catch (SQLException E) {
// System.out.println("SQLException: " + E.getMessage());
// System.out.println("SQLState: " + E.getSQLState());
// System.out.println("VendorError: " + E.getErrorCode());
%></body></html>
Now if I uncomment the commented code I get no error but I also get no
results which is wrong.
I'm thinking there is a priviledge problem. The mysql database is set up
to alloow any user to connect.
Any help would be greatly appreciated.

I had this problem a few days ago myself and finally went to the developer of the mySQL driver. According to the developer, RedHat, for some unknown reason, maps
127.0.0.1 to "localhost.localdomain". To fix the problem, I had to change the host in my db table from "localhost" to "localhost.localdomain". In my URL, I still used 'localhost'. I also did this in my user table.
Example:
Update user set host = "localhost.localdomain"
where host = "localhost";
Update db set host = "localhost.localdomain"
where host = "localhost";
This works for me through JDBC on Redhat.
Maybe you can help me. Where did you put your driver class files? I tried putting them in WEB-INF/lib and that didn't seem to work. I tried putting them in WEB-INF/classes and that didn't seem to work either. I keep getting, "no suitable driver" which means it has something to do with the CLASSPATH. Unfortunately, since I am using a hosting company that is unfamiliar with servlets, I am limited on what I can get them to do.

Also setup classpath...

"Connection refused: connect"
This means there is no service running on the host and port you are trying to connect to.
Try
telnet localhost 3306
If this fails to connect then nothing will work until either the service is running correctly.

Getting an error in JDBC mySQL Connection

Hi,
I am creating JDBC mySQL Connection error.
The eror messsage is
Incorrect name parameter jdbc:mysql://10.114.16.70:3306/kaushikb root,pass in naming operation.where root is the username and pass is the password and kaushikb is the database name.
I am entering the tablename as: emptable.
Regards
Taton
Edited by: Taton on Dec 11, 2008 3:15 PM

Let me guess: you did
getConnection("jdbc:mysql://10.114.16.70:3306/kaushikb root,pass");rather than
getConnection("jdbc:mysql://10.114.16.70:3306/kaushikb", "root", "pass");

Hi!
I also have the same problem (I also test the sample in this case but still got the same error. When I use a standard java client then I can acess mySQL database without any problem, this just occurs when trying to access the database from a JSP page.
CLASSPATH=
C:\Program\RDBMS\mySQL\mysql-connector-java-2.0.14\mysql-connector-java-2.0.14-bin.jar
Please need som advice on this.

That is a good idea for actual implementation, but this is just a test. There isn't any reason that this should not work because it hasn't been broken up into multiple files etc.Evidence would indicate that it is not in fact working though. And the error indicates a syntax error. Because it is JSP there is no assured way to localize the problem, not to mention that since it is running is a container there is no assurance that the posted code is even what is running.
My suggestion on the other hand completely eliminates all of those possibilities.
But if it helps you the posted SQL does not have any syntax errors. So if you can solve the problem that you have knowing just that then go for it. Myself I would at least create a test jig.

Very urgent !!!!!!!! Jdbc error mysql error

hii
i am not been able to connected to d/b ,i am using mySQL..

I created a war in java studio creator2 , export war file and deploy it by TomCat manager, After that ,when I launch a page at the first time , I got the following error
com.sun.rave.web.ui.appbase.ApplicationException: org.apache.jasper.JasperException: java.lang.RuntimeException: com.mysql.jdbc.NotImplemented: Feature not implemented

Serious problem of jdbc-mysql connectivity using tomcat

hi everybody
i m in serious problem since last 15-20 days. i m trying hard to make the connection jdbc-mysql using tomcat with the help of a jsp test page but every time i am facing almost the similar probems listed below in detail:
to make sure that the jdrivers's .jar (mysql-connector-java-3.1.7-bin.jar) available for such connections working fine i have tried the above said connection without using tomcat....which is working fine...for this i have created a dummy database with a dummy table ..and written some queries in the .java file of my code which upon running inserts the specified values in the defined(dummy) database.
this is the confirmation that the classpath etc..are ok in regard to the mysql-connector-java-3.1.7-bin.jar
now i have placed a copy of this .jar file in to the commons/lib directory of the tomcat web server(which is suppossed to be the place for such external jars)
after doing so i have followed 2 methods :
method 1st:........
i have made aone more jar file from the following .java file....
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class TestSQLLoad
String user = "Not Connected";
String pwd = "no pwd";
int id = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null ) {
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
user = "Got Connection "+conn.toString();
Statement stmt = conn.createStatement();
String q = "select name, password, id from user";
ResultSet rst = stmt.executeQuery(q);
if(rst.next()) {
user=rst.getString(1);
pwd=rst.getString(2);
id = rst.getInt(3);
conn.close();
}catch(Exception e) {
e.printStackTrace();
public String getUser() {
return user;
public String getPassword() {
return pwd;
public int getID()
return id;
after compiling it at the cmd prompt i made a .jar file from the .class of it and named it MySQLLoad.jar...then i placed it also in to the commons/lib directory where the mysql-connector-java-3.1.7-bin.jar was already placed.
then i have changed the server.xml and web.xml files from the conf directory of the tomcat as given here:
server.xml

after all this i have taken a jsp page whose code is here:
(the mysql database used is named as "testdb" and the table name is "user" which is having fields name,password and id)
<html>
<head>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
and placed it in to the Tomcat 5.5\webapps\tomcat-docs\testdb directory and saved as test-db.jsp
when i run this page on the browser i get a lot may errors stating
org.apache.jasper.JasperException: Unable to compile class for JSP

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.4 logs.
AND NOW WHEN just to get rid of such errords i try to include a statement
<%@ page import="pkg.TestSQLLoad" %> in the jsp page code (and also place the MySQLLoad.class file in a folder called pkg and place it in the same directory where the jsp page is )and make it look like
<html>
<head>
<%@ page import="pkg.TestSQLLoad" %>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
now when i run it i get the following errors:

in response to the above error i have even tried placing the MySQLLoad.class directly in the testdb folder along with the jsp page without keeping it in a package named pkg and then importing directly as <@page import="MySQLLoad" %>
that too gave me the following errors

and if i do not use the statement <%@ page import="MySQLLoad"%> then also i get the errors like

THE 2nd Method:
in my second method i did the same changes in the web.xml and server.xml
then i took a jsp page with the following code:

so better if u plz guide me in that regard

JDBC/MYSQL Connection problems

I'm new to using JDBC so I'm not sure if I'm simply doing something wrong in my code or if I've installed something incorrectly. I've got the JDBC connector/J installed properly as far as I can tell. At least when I run my code I'm not getting an error about the driver not being found. The problem I'm running into is that even though I've double and triple checked the authentication info I keep getting the following error:
Exception in thread "main" java.sql.SQLException: Invalid authorization specification message from server: "Access denied for user: '[email protected]' (Using password: YES)"
The actual connection commands I'm using are as follows:
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/Test", "testusr", "testpwd");
I've checked and rechecked the spelling of my mySQL user & password and as far as I can tell, they work just fine so I can't figure out why I would be getting this error. Any suggestions on things I can try or does anyone see any obvious errors in what I'm doing?

The failure is caused not by the JDBC driver but by how the MySQL was configured
when it was installed. By default, MySQL is configured to allow connections that
are created only from within the localhost.
The line
DriverManager.getConnection("jdbc:mysql://localhost:3306/Test?user=testusr& password=testpwd") translates to "create a connection to MySQL running at 'localhost' and use the
'testusr@<hostname.domain>' as user name and 'testpwd' as the password".
If you can see, the <hostname.domain> is replaced with "other value" aside from
the "localhost" which you expect, hence connection is denied.
The '<hostname.domain>' is replaced with the value of either your IP address or
hostname. Therefore, any connections created from outside the host where your
server is running will be denied. Now, making the 'host' value set from
'localhost' to '%' would tell MySQL that you are allowing connections created from
outside the MySQL host to connect to the server.
Another way to go around this is problem is to modify your
"\Windows\system32\drivers\etc\hosts" OR "/etc/hosts" file and give
your loopback address (127.0.0.1) another alias (aside from localhost), e.g.:
127.0.0.1 localhost <hostnameY.domain>
192.168.1.1 <hostnameX.domain> <hostnameY.domain>where you replace <hostnameY.domain> with the name/alias of your computer in
the network. The domain is optional and depends upon the domain name that
your network is using.

JDBC, MySQL and the rudeness of SQLExceptions

Hi there
I'm having an annoying problem (no, really?).
I've got a MySQL database running on a nice little Red Hat Linux server. It works just fine, and I can access it remotely from my windows desktop. So I'm trying to write a little client app.
I'm using Windows XP with Java2 v1.4.01. For my JDBC drivers I'm using Connector/J (formerly mm.mysql). The connector/J jar is in jre\lib\ext. I have also unpacked it to C:\Java\Connector and linked directly to the jar in my CLASSPATH environment variable.
So everything sounds right so far, yeah?
Trouble is, every time I try to connect I get a rude "No Suitable Driver" error. I've searched extensively for material about this problem, but no solution I've tried seems to work. Any comments, suggestions etc will be appreciated.
The test code is quoted below:
import java.sql.*;
public class MySQLClient{
private boolean connected;
private Connection conn;
public MySQLClient(){
     connected = false;
public boolean Connect(String userName, String userPwd){
try {


Hmmmm code was cut off. Here it is again.
import java.sql.*;
public class MySQLClient{
private boolean connected;
private Connection conn;
public MySQLClient(){
     connected = false;
public boolean Connect(String userName, String userPwd){
try {
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     conn = DriverManager.getConnection(
"jdbc:mysql:190.100.7.1:3306", userName, userPwd);
     connected = true;
     System.out.println("Connect OK!");
     } catch (java.lang.ClassNotFoundException e){
System.err.println("Can't find the freakin' driver");
     System.err.println(e.getMessage());
     } catch (java.lang.InstantiationException e){
     System.err.println("WTF???");
     System.err.println(e.getMessage());
     } catch (java.lang.IllegalAccessException e){
System.err.println("Illegal access");
     System.err.println(e.getMessage());

JDBC MYSQL Connection Problem

Hi guys I have created a database called books in MySQL and I have the following code to test the link of connection. I am using Netbeans.
import java.sql.*;
public class jdbcexample1 {
/** Creates a new instance of jdbcexample1 */
public jdbcexample1() {
* @param args the command line arguments
public static void main(String[] args) {
// TODO code application logic here
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql:///books", "jhtp6", "jhtp6");
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) {}
However my program when run gives me the exception message which is
"Exception: com.mysql.jdbc.Driver"
Before you tell me, I have put the "mysql-connector-java-3.0.14-production-bin" in the ext folder of jre and I have also appended the CLASSPATH as follows.
".;C:\PATH\mysql-connector-java-3.0.14-production-bin.jar;" which leads to the jre ext folder.
What am I doing wrong, Have I missed something above and if not what could be wrong with my setup.
Thanks!! :)

Helo,
I have just started with java, I am also using netbeans, I used similar code to test the link, the code gives the following error when compiled:
java.lang.NoClassDefFoundError: JdbcExample1
Exception in thread "main"
Java Result: 1
The code I used is a s follows:
package com.stardeveloper.example;
import java.sql.*;
public class JdbcExample1 {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql:///pet", "root", "siemens");
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) {}
Pls help..
Thanks..

Here's the code I'm using:
<%
     Class.forName("org.gjt.mm.mysql.Driver").newInstance();
     java.sql.Connection conn;
     conn = DriverManager.getConnection("jdbc:mysql:numbers", "username", "password");
%>
If anyone knows how to fix this, I'd appreciate any help!

Hi,
Three things:
1. I presume numbers refers to the prot you are accesaing mysql - i tend to use default 3306.
2. If there are problems recognising DriverManagaer are you importing java.sql.*; I'm sure you are.
3. I think the sun.tools.javac.Main error relates to the tools version that you are using, although I would not guarantee this. The tools.jar in later versions of tomcat is twice the size of earlier versions and you have to ensure this is the version that your application is checking for. A quick test for this is to put the newer version(size 74k) into WEB-INF \lib directory where an application looks first for complied java files.
best,

What is the error message?
I advice you to use prepared statement for batch inserting.
