I need to know how its stored into mysql database.
which jar file is used for creating the connection with mysql database .
Thanks,

The connection objects are store in the CI_APPOBJECTS repository table with SI_KIND='Metadata.DataConnection' . The connection properties are stored as property bags along with your objects.
Unfortunately I have just found a reference that this kind of access in not fully supported though and you may have to use the Universe Designer SDK (COM based)
Change password of Universe connection using Java SDK?
Since you are working with the SDK it will make sense to post your questions here:

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));

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>

Cannot establish mysql database connection with j2ee application

Hello All,
I started studying J2EE technology about a month back. I have this simple application involving a couple of servlets and jsps. The code is from a reliable source , so I know that there is nothing wrong with the prog code. Now the code uses a simple database, where I am stuck! I just can't connect to the database Mysql.
I downloaded Mysql database from the mysql site.
I downloaded JDBC driver for mysql from the same site.
Can somebody please tell me which files(from the driver that I downloaded) have to be unzipped to jar files to be set in the class location?
Any help is highly appreciated.
Thanks

MySQL Database Connection (two databases at the same time)

I have never had to open more than one MySQL database from within the same website before, but I do now. The website I have is designed where all the content comes from within the main database. I am building an Inventory system that I want within it's own database, in the event I would ever need to move the application to another server or something, I don't want this data residing in the main database.
Currently, I open the database connection from within a file called "common.php" that resides in a directory called "lib" that can be accessed from the root directory. Below is the proposed code that would be placed within the "common.php" file:
// Define Database Variables
$dbserver = "127.0.0.1";
$dbuser = array('clevelan_user1', 'clevelan_user2');
$dbpass = array('P@ssw0rd', 'P@ssw0rd2');
$dbname = array('clevelan_database1', 'clevelan_database2');
// Start Session
session_start();
// Connect to Databases
connectdb($dbserver, $dbuser[0], $dbpass[0], $dbname[0]);
connectdb2($dbserver, $dbuser[1], $dbpass[1], $dbname[1]);
// Database 1 Connection
function connectdb($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection;
$connection = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db = @mysql_select_db($dbname, $connection) or die ("could not select databsase");
return $connection;
// Database 2 Connection
function connectdb2($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db

//End of Code Within the "common.php"
From within any page of the website, I want to access both connections by placing an include at the top of each page:
include_once("lib/common.php");
Currently, when I run the code above, any page within the website (the home page) provides error messages with regards to database connectivity (the pages are looking for there content from within the second database. It's as if the second database is the only database seen by the website.
I need help figuring out how I can have two MySQL databases open at the same time (the second database will only be open for short periods of time and then closed). But the main database is always open.

Create one project using one copy of the exact tables.
create 2 different sessions.xml files each pointing to the same project. Set the login information in the sessions.xml files.
That should work fine.

MySQL database connections supported?

Hi,
I am trying to connect to mysql database using the 'write to database' and 'query database' activities of utilities.
I have used it successfully for MS SQL but am not able to work with MySQL. I have created the ODBC connection to MySQL database and am able to successfully test connection to mysql database from the 'odbc datasource administrator' window of administrative
tools.Also able to retrieve the databse names in this window.
However when I run the write to DB activity to use this ODBC connection, i get the below error (tkt is the name of the 'table').
Database error has occurred. [MySQL][ODBC 5.3(a) Driver][mysqld-5.6.21]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''tkt'' at line 1
Code = 80040e14
Code meaning = IDispatch error #3092
Source = Microsoft OLE DB Provider for ODBC Drivers
Description = [MySQL][ODBC 5.3(a) Driver][mysqld-5.6.21]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''tkt'' at line 1
Any compatibility issues or anything else?

Hello,
I can reproduce the issue with exactly the same error code. Query database ran without problem except write to database. I also tried to use SQL server instead, and it succeeded.
I saw the same error with SQL server at first because I used the wrong database. So I’m not sure if we need additional implement with MySQL.
As suggested, run the same task with script should be a good workaround.

CS3 mysql database connection using php

Hi, this is my first time trying to connect to a database. I have created a mysql database with my hosting provider. I am also configured to use php. I have ready numerous threads on this topic, but am still confused.
I am getting the following error message:
When I enter the following information into the connection string, I get the following error Error http error code 404 file not found. The site does not map to ftp.readyhosting.com/_mmserverscripts/mmhttdb.php Is the location of mysql server correct? Connection name ? user defined ?aosprod?
Mysql server = aoswebeditor.readyhostingmysql.com. Also, this is not the same location as the web server.
The hosting company provides the following php code to connect to the database.
<?php
$link = mysql_connect('aoswebeditor.readyhostingmysql.com', 'aosweb', '*password*');
if (!$link) {
die('Could not connect: ' . mysql_error());
echo 'Connected successfully';
mysql_select_db(aos);
?>
Because of the connection dialog boxes in CS3, I have not used this php code but only used the mysql server aoswebeditor.readyhostingmysql.com.
My requirements are very simple, I want to use the same remote database for the dreamweaver connection for the remote and testing server.
Any ideas would be appreciated.
Thanks. George

First of all, you seem to be mixed up about terminology. ASP stands for Active Server Pages, and is a type of server technology similar to PHP. I think you mean ISP (Internet Service Provider). However, this is not correct, either. An ISP provides your connection to the internet. Although some ISPs also host websites for their customers, your website is normally located at a hosting company. You need to get that mixup out of the way. Otherwise, you might confuse people with future questions about ASP, when you actually mean something completely different.
OK, lecture over...
Your hosting company is following standard procedure by preventing remote access to MySQL databases. However, Dreamweaver does make it possible to use your remote database and website for testing purposes. It does so by uploading a hidden folder called _mmServerScripts to your remote server. This performs a local connection with your database, and then sends the results back to your local computer. When setting up your testing server definition in Dreamweaver, you need to provide the details as I indicated before. When creating a MySQL connection in Dreamweaver, fill in the server name and account details as given to you by your hosting company. If everything is set up correctly, you should be able to use your remote server and database for testing.
Having said that, it is much better to install a local testing environment. You'll find it faster, and it also lets you make mistakes (an essential part of the learning process) in the security of a closed environment. For details of how to set up a local testing environment, see this article in the Adobe Developer Connection.

Mysql database connection with Labwindows/CVI 2009 sql toolkit

Dear experienced users,
I am using the following software/hardware:
Windows 7/ Mysql database 5.6.15 64-bit with MySql ODBC 5.2 Ansi driver installed
Labwindows/CVI 2009 with sql toolkit
The user DSN of ODBC Data source administrator have been confiugred to one of mysql database. The test MYSQL Connector/ODBC is succesful.
The Labwindows/CVI build setting is configure to debug64 after trying debug (32)
The source code is from the example readtab.c with changes to the dsn I am testing
hdbc = DBConnect ("DSN=dvd_collection");
The error message I have is confusing me.
(it is in the attachd png)
I thought it was due to the 64 bit mysql database. That's why I tried the 64 bit build from Labwiondws/CVI. I alsow tried Labview DB tools open connect.vi. It shows me the same error.
Any suggestion is appreciated.
Thanks,
Jimmy

I always use connection strings of the form "DSN=datasourcename;UID=database_user_id; PWD=database_user_password".
Where:
datasourcename = The name of the connection defined in the ODBC connection.
database_user_id = One of the user identities created by the database administrator. Obviously the administrator will lock down the permissions appropriate to the task in hand.
database_user_password = The password that identifies database_user_id, again set by the database administrator.
Note that while it is obviously desireable to lock the permissions down as far as possible on the MySQL server, the more you do so, the slower the database will run, because of the way mySQL searches the permissions tables.

MySQL database connection: Communications link failure Last packet sent to the server was 0 ms ago.

Hello,
I am trying to connect to an external MySQL database from within a bundle.
But I keep getting this error:
Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure Last packet sent to the server was 0 ms ago.)
These are the details of my bundle:
1)          Spring bundle(using Spring DM)
2)          MySQL database is at port 7046 so my bean is as below:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
                    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
                    <property name="url" value="jdbc:mysql://instance13550.db.xeround.com:7046/jas" />
                    <property name="username" value="mysql" />
                    <property name="password" value="mysql" />
</bean>
My bundle connects to the mysql database from withina local felix installation. But when I put the same bundle within CQ I get the error.
Please help.
Karan

I dont know the answer, but if you google for this, some articles listed might help:
re: "Communications link failure Last packet sent to the server was"
Note: I use 're:' which is short for 'reply',
I think you will also be better off using preparedStatements. Dont forget to use preparedStatement.clearParameters() just before preparedStatements.setString() items in the loop
Also, I question why you need to test having 1000 test users all banging away at your application at once. Chances are, most will be staring at your web page and only a few will ever hit the update/insert button
within the same 100 milliseconds or so that your process takes to update.

your error means that your program can not load the class specified.
you have to put the driver jar file (in mysql case it named "mysql-connector-java-3.1.12-bin.jar") put it in your class path.
the easiest and famous class path is:
%JAVA_INSTALLATION_PATH%\jre\lib\extGood Luck

Mysql DataBase connectivity with PI 7.1

Dear Experts,
I need to connect Mysql DB table to access the data using PI 7.1 and pass it to ECC RFC.
I have configured the sender JDBC channel details as below
JDBC Driver : com.mysql.jdbc.Driver
Connection : jdbc:mysql://<Server>:<port>/<database>
But it showing the below error while starting my Sender channel in RWB.
We already install the above driver com.mysql.jdbc.Driver in PI again it shows the same error.
Kindly help to resolve this issue.
Best Regards,
Monikandan

Hi Monikandan,
Looks like the driver installation was done properly. You need to check if the installation was proper and re-deploy with proper steps.
