Can't use captcha from tomahawk library

I'm trying to use the captcha component from tomahawk, <t:captcha>. Everytime the page loads, the following error appears:

com.sun.facelets.tag.TagException: /tiles/competitionSite.xhtml @112,46 Tag Library supports namespace: http://myfaces.apache.org/tomahawk, but no tag was defined for name: captcha

I think there's something wrong with the libraries. I checked the tomahawk JARs and <t:captcha> should be supported in Tomahawk 1.1.7 or higher. I used multiple versions (e.g. 1.1.13), but <t:captcha> never worked. All the other tags like <t:inputText> are working fine. I also imported the batik-awt-util-1.6-1.jar, because that's necessary for captchas.

Maybe there's a problem with my other libraries? I can't exchange them easily, because there are many dependencies. Here's a list of them:

batik-awt-util-1.6-1.jar
commons-beanutils-1.7.0.jar
commons-codec-1.3.jar
commons-collections-3.1.jar
commons-digester-1.6.jar
commons-el-1.0.jar
commons-lang-2.1.jar
commons-validator-2.1.jar
el-ri.jar
jakarta-oro.jar
jboss-serialization.jar
jsf-facelets-1.1.12.jar
jstl-1.1.0.jar
myfaces-api-1.1.5.jar
myfaces-impl-1.1.5.jar
org.springframework.web-3.0.5.jar
richfaces-api-3.1.6.GA.jar
richfaces-impl-3.1.6.GA.jar
richfaces-ui-3.1.6.GA.jar
tomahawk-1.1.13.jar
urlrewrite-2.6.0.jar

Thanks for your help!

Solution

I just found the mistake. In our CMS the tomahawk.taglib.xml file will not be deployed dynamically from the included JAR. I just had to create a new entry like this:

  <tag>
    <tag-name>captcha</tag-name>
    <component>
      <component-type>org.apache.myfaces.CAPTCHA</component-type>
      <renderer-type>org.apache.myfaces.CAPTCHA</renderer-type>
    </component>
  </tag>

Now I use <t:captcha> with tomahawk-1.1.7.jar and batik-awt-util-1.6-1.jar.
