JSP contacting MySQL database

I want to make a simple Login page that queries a MySQL database. Can someone please tell me if they know of documentation that can take me through easily?

Connection to any database is alike. Only the database drivers differs. If I am not wrong, this is the string to get connected to MySql database.
Class.forName("org.gjt.mm.mysql.Driver");
Connection con=DriverManager.getConnection("jdbc:mysql://200.200.200.200/xxxxxx","xxxxxx","xxxxx");
where first xxxx is the dsn name, and the second xxxx is the userid and the third xxxx is the password to get connected to the mysql database.
Hope it helps

[b][u]JSP create mysql DataBase problem[/u][/b]

While i try to create mysql database through JSP program using query,

The code is as follows : Please Help Me......
try {
Connection con = null;
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
con=DriverManager.getConnection("jdbc:mysql://localhost:3306/bedrock","Dude1","");
try {
Statement stmt=con.createStatement();
stmt.executeUpdate("create database employee;");
System.out.println("Statement Executed");
catch(Exception e) {
System.out.println("Statement not Executed");
catch (SQLException ex) {
while (ex != null) {
System.out.println("sql exception"+ex);
ex = ex.getNextException ();
" THANKS IN ADVANCE "

It's not common to create databases with Java. I'd say this is especially true of JSPs. You'll have to GRANT permission to access and create tables to every single user that comes in? Are those tables cleaned up when users are done, or does the number of tables grow as the number of users grows? One table per customer? Sounds more like session or cookies to me. Do you validate users to make sure that only authorized users can create tables? Lots of problems, and it doesn't appear that you've addressed any of this from the code you've posted.
It's a bad idea to have code like this in a JSP. Those are for view only. Better to put database code on the server side where it belongs.

Jsp JST MySQL - database connection

Hello
I am facing a database connection problem. I want to connect to mysql database fro a jsp page that uses JSTL taglibs.
I am using Tomcat 5.x, JSTL 1.1. MySQL 5x
I have copied jstl.jar, standard.jar and mysql driver in the \WEB-INF\lib dir of my application.
If I connect to the database using scriptlet it works. But If I connect using the sql taglib, it gives me the error
2008-01-22 14:20:12 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver"
my jsp file is as follows
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="firstName">request.getParameter("name")</c:set>;
<%= request.getParameter("name") %>
<sql:setDataSource
var="myDS"
scope="request"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/contact_db"
user="root"
password=""
/>
<sql:query var="phone_book" dataSource="$(myDS)">
Select last_name, home, cell, office from phone_book where first_name = ?
<sql:param value="firstName"/>
</sql:query>
<HTML>

hi thanks
please let me know whats the better approach for getting an database connection if this is not recommended.
after some modifications i am not getting the no suitable driver error. I also updated the code as per your comments. ...yet am not seeing any results.
I have modified the file as follows.
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String firstName = request.getParameter("name");
%>
<%= firstName %>
<sql:setDataSource
var = "firstDS"
scope="request"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/contact_db"
user="root"
password=""
/>
<sql:query var="phone_book" dataSource="${firstDS}">
     Select * from phone_book where first_name = ?
     <sql:param value="${firstName}"/>
</sql:query>
<c:forEach var="phone_book" items="${user.rows}">
     <tr>
<td><c:out value="${row.no}"/></td>
<td><c:out value="${row.first_name}"/></td>
<td><c:out value="${row.last_title}"/></td>
<td><c:out value="${row.home}"/></td>
<td><c:out value="${row.cell}"/></td>
<td><c:out value="${row.office}"/></td>
</tr>

JSP contacting mysql

Im currently using this:
Class.forName("com.mysql.jdbc.Driver"); //which is the mysql-connector-java-3.0.0-beta
connect = DriverManager.getConnection("jdbc:mysql://localhost:3306/xyzDataSournce","abc","xyz");
in my source code, but my jsp doesn't seem to be contacting the xyzDatasource.
I open up winmysqladmin and discover that the driver and setup is using C:\WINNT\System32\myodbc.dll
I've also placed the mysql-connector-java-3.0.0-beta-bin.jar file in
C:\jakarta-tomcat-4.1.10-LE-jdk14\webapps\Alumni\WEB-INF\lib
and added to the class path of the system variable:
C:\jakarta-tomcat-4.1.10-LE-jdk14\webapps\Alumni\WEB-INF\lib\mysql-connector-java-3.0.0-beta-bin.jar
wat am i doing wrong?????

What is the error?

I want to know or How to connect Mysql
with JSP or JSF any other software isavailable?
please help me.....First you need to find 25 m of a CatV cable and...The DB files need to be located on the ninth device of a SCSI Daisy Chain with the total SCSI cable length being over 150 m (and the devices (and cables) need to be mix of Differential and Non-Differential).
Edit: And forget the terminator, who needs it?

I want to know or How to connect Mysql
with JSP or JSF any other software isavailable?
please help me.....First you need to find 25 m of a CatV cable and...The DB files need to be located on the ninth device of a SCSI Daisy Chain with the total SCSI cable length being over 150 m (and the devices (and cables) need to be mix of Differential and Non-Differential).
Edit: And forget the terminator, who needs it?

JSP, EJB in Jboss 4 with mySQL database. Error in connecting to database

Hi, i using JBoss 4-0-1 with jsp and mySQL database. I get this example from a book using stateless session beans. However i modify it so it can connect to mySQL database.
This is my code for jsp.
<%@ page import="asg.MusicEJB.*,
java.util.*,
javax.naming.Context,
javax.naming.InitialContext,
javax.rmi.PortableRemoteObject" errorPage="error.jsp" %>
<%--
     The following 3 variables appear in a JSP declaration.
     They appear outside the generated _jspService() method,
     which gives them class scope.
     Since we want to initialize our Music EJB object once
     and read the Music Collection database to get the
     recording titles once, we place this code inside
     method jspInit().
     The EJB business method getMusicList()
     returns a collection of RecordingVO objects which we
     store in ArrayList albums.
--%>
<%!
     MusicHome musicHome;
     Music mymusic;
     ArrayList albums;
     Properties properties=new Properties();
     public void jspInit() {
               properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
               properties.put(Context.PROVIDER_URL, "localhost:3306");
               System.out.println("............................in properties");
          try {
               //Context initial = new InitialContext();
               InitialContext jndiContext = new InitialContext(properties);
               //Object ref = jndiContext.lookup("MusicEJB");
               Object objref = jndiContext.lookup("java:comp/env/ejb/EJBMusic");
               musicHome = (MusicHome)PortableRemoteObject.narrow(objref, MusicHome.class);
               mymusic = musicHome.create();
               albums = mymusic.getMusicList();
               System.out.println(".............................in line 64");

     RecordingVO objects. These variables will all be available
     to other pages within the session.

Unable to connect JSP and MySQL

Hi, I am new to this forum
I've started developing web pages using JSP
I've the problem connecting JSP and MySQL database. I've created the page that retrive records from mysql table. But the connection fail to access to database it gives me this error:
org.apache.jasper.JasperException: Exception in JSP: /retreive_book.jsp:15
The code is:
12: <%
13: //Class.forName("com.mysql.jdbc.Driver").newInstance();
14: Class.forName("org.gjt.mm.mysql.Driver");
15: connection = DriverManager.getConnection(connectionURL,"","");
16: statement = connection.createStatement();
17: rs = statement.executeQuery("SELECT * FROM books_detail");
18: %>
And the connectionURL parameter has this value:
String connectionURL = "jdbc:mysql://localhost:3306/books?username=;password=";
root cause msg is:
java.sql.SQLException: Invalid authorization specification: Access denied for user 'nobody'@'localhost' (using password: NO)
Please can anyone help me. It is 3 days now trying to do that but not succeded yet

Hi
Yes It is true that my MySQl installation its username is root. So how should put that in the url. Cause I did that but it didn.t work
String connectionURL= "jdbc:mysql://localhost:3306/books?username=root;password=";
If I write in that manner is it correct for root username or should I put a single quote
Thanks

I read this doc - [http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html], this applicable if I Tomcat Admin, but i'am not Admin
I simply user, i.e. I want to place its database on virtual host (Tomcat+(JSP-JSTL)+MySQL).
There is idea how can resolve this problem
Thank you in advance ;)

For all how have similar problem.
Decision instead of these ways
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
it is necessary to indicate these
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

Sending colour from a JSP page into a MySQL database field

Dear All,
I am working on trying to send different colours into a MySQL database field from a JSP page.
This is so that I can represent different pieces of data on my webpage tables in different colours providing status depending on the user request.
What is the best way to write JSP code for this?
thanks,
Alasdair

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");
} catch (Exception ee) {
ee.printStackTrace();
%>
</body>
</html>

Learn JDBC API: [http://java.sun.com/docs/books/tutorial/jdbc/index.html]. Create a DAO class which uses JDBC to interact with Java and takes or returns the desired data in form of DTO's. Use and test it as a plain vanilla Java application with a main() method. This require a JDBC driver (a concrete implementation of the JDBC API) in the classpath. MySQL offers JDBC drivers as download at their homepage, it is called "Connector/J".
Once you got the JDBC part to work, create a Servlet class which holds an instance of the DAO class and uses its methods to interact with the database. In the doGet() you can place logic to preload data from the DAO class for display. In the doPost() you can place logic to process data for create, update or delete using the DAO class. Finally let it forward the request to a JSP.
In the JSP you can use JSTL/EL to display data. For tabular view you may find the JSTL c:forEach useful. For plain display, just use EL the usual way.
