を参考にBehaviorを実装してみたがbehavior-classが見つからないエラーが発生してしまう。

エラー

javax.faces.FacesException: Could not find any registered behavior-class for behaviorId : confirmation
	at org.apache.myfaces.application.ApplicationImpl.createBehavior(ApplicationImpl.java:1182)
	at javax.faces.application.ApplicationWrapper.createBehavior(ApplicationWrapper.java:113)
	at org.apache.myfaces.view.facelets.tag.jsf.BehaviorTagHandlerDelegate.createBehavior(BehaviorTagHandlerDelegate.java:102)
	at org.apache.myfaces.view.facelets.tag.jsf.BehaviorTagHandlerDelegate.applyAttachedObject(BehaviorTagHandlerDelegate.java:137)
	at org.apache.myfaces.view.facelets.tag.jsf.BehaviorTagHandlerDelegate.apply(BehaviorTagHandlerDelegate.java:71)

以下は上記サイトを参考に実装した内容。

ConfirmBehavior.java

@FacesBehavior(value = "confirmation")
public class ConfirmBehavior extends ClientBehaviorBase {
    @Override
    public String getScript(ClientBehaviorContext behaviorContext) {
        return "return confirm('Are you sure ?');";
    }
}

taglib.xml

<namespace>http://www.rubus.be/jsf/tutorial</namespace>
<tag>
    <tag-name>confirmation</tag-name>
    <behavior>
        <behavior-id>confirmation</behavior-id>
    </behavior>
</tag>

confirm.xhtml

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:r="http://www.rubus.be/jsf/tutorial"
...
<h:commandButton value="with confirmation" actionListener="#{bean.performAction}">
    <r:confirmation/>
</h:commandButton>
...
</html>

ConfirmBehavior.javaがbehaiviorとして読み込まれていないのが原因のようだったので、faces-config.xmlに追加してみたらうまくいった。

faces-config.xml

<behavior>
	<behavior-id>confirmation</behavior-id>
	<behavior-class>xxx.ConfirmBehavior</behavior-class>
</behavior>
