似乎JSF尝试访问方法，就好像它是属性一样。
CollaborateursBean.java
public class CollaborateursBean implements Serializable {
....
public void ajouter(ActionEvent e)
{
System.out.println("DO SOMETHING");
}
}

这是启动Tomcat时遇到的异常：
**Property 'ajouter' not found on type com.steriamedshore.proboard.view.referentiel.collaborateurs.CollaborateursBean

这是如何引起的？如何解决？
