Erro ao iniciar Tomcat 7

Front-end
#1

Bom, ao tentar iniciar o tomcat da o seguinte erro:

java.lang.OutOfMemoryError: PermGen space
	at com.sun.faces.config.ConfigManager.releaseFactories(ConfigManager.java:808)
	at com.sun.faces.config.ConfigManager.initialize(ConfigManager.java:446)

Exception in thread "main"

Obs: o erro passou a ocorrer depois que importei o jsf-facelets.jar

Alguém ?

Bom, descobri que esse erro ocorre apenas colocar a seguinte configuração no web.xml (para habilitar o facelets)

  <context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
</context-param>

<context-param>
    <param-name>facelets.DEVELOPMENT</param-name>
    <param-value>true</param-value>
</context-param>

<context-param>
    <param-name>facelets.SKIP_COMMENTS</param-name>
    <param-value>true</param-value>
</context-param>

<context-param>
    <param-name>com.sun.faces.validateXml</param-name>
    <param-value>true</param-value>
</context-param>
