BotDetect Java CAPTCHA Generator

3. Add BotDetect Java CAPTCHA Library Dependency

Here is how to add BotDetect Java CAPTCHA Library dependency in various dependency management scenarios:

The free version of BotDetect Java Captcha is available as a maven artifact:

1) Add BotDetect public maven repository (NetBeans 8):

Windows -> Services -> Maven Repositories -> Add Repository:
https://git.captcha.com/maven.git/blob_plain/HEAD:/

2) In pom.xml file, dependency should be added:

<dependency>
  <groupId>com.captcha</groupId>
  <artifactId>botdetect-jsf20</artifactId>
  <version>4.0.beta3</version>
</dependency>

<repository>
  <id>captcha</id>
  <name>BotDetect Captcha Repository</name>
  <url>https://git.captcha.com/maven.git/blob_plain/HEAD:/</url>
</repository>

In case your application uses JSF 1.2 you will need to add botdetect-jsf12 instead of botdetect-jsf20.

4. Register BotDetect Captcha Servlet

Update your application configuration (web.xml) file.

<servlet>
  <servlet-name>BotDetect Captcha</servlet-name>
  <servlet-class>com.captcha.botdetect.web.servlet.CaptchaServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>BotDetect Captcha</servlet-name>
  <url-pattern>/botdetectcaptcha</url-pattern>
</servlet-mapping>
