What Is MySqlJavaClient?

MySqlJavaClient is an application written in Java which allows you to connect to a MySQL database over a network (including the internet), issue database queries in SQL, receive the results of those queries, and display them in tabular form. Information about the MySQL database management system is available from MySQL AB at http://www.mysql.com In many situations, it is free.

If you need information about how to administer and/or use a MySQL database, consult their tutorial and manual at http://www.mysql.com/documentation/

If you need information about the SQL language, invented at IBM by the way, consult the same tutorial or the later chapters of any book by Roger Jennings.

What Versions of MySqlJavaClient Are Available?

At any given time, only one will be available. The current release is an expiring beta release, beta 0.3. It expires exactly six months from March 12, 2001. As new releases become available, they will be posted to this Web site, where they will replace previous releases. Because MySqlJavaClient is written in Java, only one release is needed, as it will run on any system on which the Java Development Kit, version 1.2.2 or higher, is installed.

Basic Information About MySqlJavaClient

The final release of MySqlJavaClient will probably be copyrighted (copyleft?) under one of the GNU licenses, but until then, MySqlJavaClient is copyright Charles W. Neville, March 2001, all rights reserved.

This expiring beta release expires exactly six months from March 12, 2001. Until then, it may be freely downloaded and used by anyone, provided it is neither modified nor sold for profit.

As with anything else that is free, this beta release is provided as is, and there are no guarantees or warrantees of any sort, either expessed or implied. In no event will the copyright holder(s) be liable for any damages resulting from the use of this software. Use at your own risk.

System Requirements

To run this beta release of MySqlJavaClient, you need the Java Development Kit -- JDK 1.2.2 or higher -- installed. You should be able to run this beta release on any machine for which a suitable version of the JDK is available. To run this release by double clicking MySqlJavaClient.bat, you need to be running Windows 98 or higher, or NT 4.0 or higher.

MySqlJavaClient is an ordinary Java application. The name of the Java class file is MySqlJavaClient.class. To run MySqlJavaClient under Mac OS 9, Mac OS X, Linux, Sun Solaris, etc., etc., run it the way you run any other Java application in your operating environment. You will have to set the classpath first; read the .bat file (included with the distribution) to see how.

The JDK is available for free for many operating systems from Sun Microsystems at http://java.sun.com/

How to Download and Install MySqlJavaClient

MySqlJavaClient can be installed by simply downloading, unzipping, and moving a folder to a convenient place. As the installation process does not write to the Windows/NT registry, it is easy to install and run MySqlJavaClient from a Temp directory, a Zip disk, or even a floppy disk. This is a great advantage in shared laboratory environments, where you may not have the administrator privileges required for most software installations. In detail, you download and install MySqlJavaClient by

  1. Download Readme.txt, and read it. It contains more copyright information, installation directions, operating instructions, and important cautions. (Downloading .txt files can be tricky.

Netscape Navigator will display the file in the browser window, typically with no line breaks. Simply press Select All from the Edit menu to select all the text, and then press Copy from the Edit menu to copy the text to the clipboard. After that, start your favorite text processing program (Notepad?, UltraEdit?, Wordpad?, Word?, Word Perfect?), press Paste from the Edit menu to paste the text into new document, and then save the document in a convenient place.)
  2. Download MySqlJavaClientb03.zip This contains the distribution. Downloading this is typically easy. Just click on the link.
  3. To install MySqlJavaClient, you will need to unzip MySqlJavaClientb03.zip. You probably have a zip utility such as WinZip installed on your system, but if not, a public domain DOS command line version of the zip utilities zip.exe and unzip.exe are available on this Web site. To find out how to run them, type zip -h and unzip -h. Be sure to type zip -L to read the copyright and license agreement.
  4. Complete installation and uninstallation instructions are contained in the Readme.txt file.
