JSF CAPTCHA

JSF CAPTCHA Integration How To Guide

Protecting your JSF forms with BotDetect Java Captcha requires a few steps. To find out about each of them, follow the links given bellow:

• Add BotDetect library in the classpath
• Register CaptchaServlet
• Display Captcha protection on the JSF form
• Validate Captcha user input during JSF form submission

JSF Basic CAPTCHA Example

This code example shows the most basic source code required to protect a JavaServer Faces form with BotDetect CAPTCHA and validate the user input.

It can be used as a starting point when you are first learning how to use BotDetect.

The JSF Basic CAPTCHA Examples are included in examples folder of the download package as bdc4-jsf20-basic-captcha-example.war and bdc4-jsf12-basic-captcha-example.war files. Deploying (unpacking) the file will create a standard JSP directory tree.

JSF Facelets CAPTCHA Example

This code example shows how to protect a JavaServer Faces form with Facelets presentation technology using BotDetect CAPTCHA and validate the user input.

The JSF Facelets CAPTCHA Examples are included in examples folder of the download package as bdc4-jsf20-facelets-captcha-example.war and bdc4-jsf12-facelets-captcha-example.war files. Deploying (unpacking) the file will create a standard JSP directory tree.

JSF Login Form CAPTCHA Example

This code example shows how to add BotDetect CAPTCHA protection to a typical JavaServer Faces login form.

To prevent bots from trying to guess the login info by brute force submission of a large number of common values, the visitor first has to prove they are human (by solving the CAPTCHA), and only then is their username and password submission checked against the authentication data store.

Also, if they enter an invalid username + password combination three times, they have to solve the CAPTCHA again. This prevents attempts in which the attacker would first solve the CAPTCHA themselves, and then let a bot brute-force the authentication info.

The JSF Login Form CAPTCHA Examples are included in examples folder of the download package as bdc4-jsf20-login-form-captcha-example.war and bdc4-jsf12-login-form-captcha-example.war files. Deploying (unpacking) the file will create a standard JSP directory tree.

JSF Login Form Filter CAPTCHA Example

The JSF Login Form Filter Captcha code example shows how to add BotDetect CAPTCHA validation to basic Login form filter in JavaServer Faces Web Applications.

To prevent bots from trying to guess the login info by brute force submission of a large number of common values, the visitor first has to prove they are human (by solving the CAPTCHA), and only then is their username and password submission checked against the authentication data store.

Also, if they enter an invalid username + password combination three times, they have to solve the CAPTCHA again. This prevents attempts in which the attacker would first solve the CAPTCHA themselves, and then let a bot brute-force the authentication info.

The JSF Login Form Filter CAPTCHA Example is included in examples folder of the download package as bdc4-jsf20-login-form-filter-captcha-example.war file. Deploying (unpacking) the file will create a standard JSP directory tree.

JSF Validator CAPTCHA Example

The JSF Validator Captcha code example shows how to integrate BotDetect CAPTCHA validation with standard JavaServer Faces page validation functionality and other validator controls.

The JSF Validator CAPTCHA Examples are included in examples folder of the download package as bdc4-jsf20-validator-captcha-example.war and bdc4-jsf20-validator-captcha-example.war files. Deploying (unpacking) the file will create a standard JSP directory tree.

CakePHP MVC CAPTCHA

CakePHP MVC CAPTCHA How To Guide

Adding BotDetect PHP Captcha protection to your CakePHP MVC applications requires a slightly different approach than adding it to basic PHP websites, but is still straightforward. This page will guide you through the necessary steps and explain the available options.

• Include BotDetect in your CakePHP application
• Display BotDetect in your CakePHP View
• Validate the Captcha in your CakePHP Controller

CakePHP MVC CAPTCHA Basic Example

This example illustrates the most basic form of BotDetect PHP Captcha protection in CakePHP MVC applications.

Alongside the Captcha image, the user is provided with an input field to retype the displayed characters. Depending on if the Captcha code entered matches the displayed one or not, a message stating the validation result is shown on the form.

The simple code showing the message in this example would of course be replaced with useful form processing code in a real world scenario.

CakePHP MVC CAPTCHA Form Validation Example

This example shows how to integrate BotDetect PHP Captcha validation and CakePHP data validation functionality. It uses Cake's FormHelper and Model validation, which provide a lot of out-the-box functionality when used together.

The example is based around a contact form which sends email if the user input is considered valid – a likely real world scenario for Captcha protection integration.

To keep the example brief, it doesn't use a database backend. Still, this type of Model integration is ideal for protecting database-driven forms that take advantage of the CakePHP Model infrastructure.

CakePHP MVC CAPTCHA Auth Example

This example demonstrates how to integrate BotDetect PHP Captcha into login and register forms in a scenario where CakePHP Auth Component is used to authenticate users to your application.

The example is based around a login form and a registration form which authenticate users and add new users if the user input is considered valid – a likely real world scenario for Captcha protection integration.
