IBM Database Connectivity for JavaScript

Client (tested configurations):

IBM® Database Connectivity for JavaScript™ clients are Web applications running in a standard browser (that is, no plug-ins or extensions need be installed).

• Operating systems: Windows® XP
• Software: Mozilla Firefox 1.5 or 2.0, Opera 9.0, or Internet Explorer 7 (with "native XHR" support both enabled and disabled). It is expected that Database Connectivity for JavaScript will run in any modern browser that supports XMLHttpRequest.

Server (tested configurations):

The server environment is a PHP container, running in a Web server, that accesses a relational database.

• Operating systems: Windows XP
• Software:
  • Web server: Apache 2.0.58 or 2.2.3
  • PHP (server): PHP 5.2.0 and PHP PDO extension
  • Database: IBM DB2® 8.2.2

Note that it should be a straightforward process to install IBM Database Connectivity for JavaScript™ on a different software stack: for example, using Linux® rather than Windows XP; or using MySQL rather than DB2. Preliminary tests show that simply supplying a different DSN parameter to the RDB constructor allows application code to seamlessly switch between different database servers. This switching is possible because the IBM Database Connectivity for JavaScript gateway accesses databases through the PDO interface.

The zip file contains three directory trees:

• js: Client JavaScript libraries
• php: Server gateway PHP code
• public_docs: JSDoc for the client libraries
• demos: demo applications

In order to use IBM Database Connectivity for JavaScript, simply include the following JavaScript files in your Web applications:

• http://yourhost:8080/jsdbc_js//messages.js
• http://yourhost:8080/jsdbc_js//rdb.js
• http://yourhost:8080/jsdbc_js//utils.js

http://yourhost:8080/jsdbc_js/ specifies the URL of the JavaScript files that are available to Web clients in your IBM Database Connectivity for JavaScript installation. For example, a Web page will read as follows:

<script language="JavaScript" 
   type="text/javascript"
src=
   "http://yourhost:8080/jsdbc_js/rdb.js">
