Button actionListener gives exception

Question

Dear All,
I have created a sample page in jsf2.0 in netbeans6.9 which gives me following error when i click the submit button.. I am quite confused because my code seems correct.
registration.jsp
<h:form>
Name:
<h:inputText value="#{loginBean.userName}" label="Name"></h:inputText>
<h:message for="Name" ></h:message>
Password:
<h:inputSecret value="#{loginBean.password}" label="Password"></h:inputSecret>
<h:message for="Password" ></h:message>
<h:commandButton value="Login" actionListener="#{loginBean.processAction}">
</h:commandButton>
</h:form>
faces-config.xml
<faces-config>
<managed-bean>
<managed-bean-name>loginBean</managed-bean-name>
<managed-bean-class>com.beans.LoginBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
</faces-config>
backing bean class
package com.beans;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.faces.event.AbortProcessingException;
import javax.faces.event.ActionEvent;
import javax.faces.event.ActionListener;
public class LoginBean{
private String userName;
private String password;
/** Creates a new instance of LoginBean */
public LoginBean() {
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getUserName() {
return userName;
public void setUserName(String userName) {
this.userName = userName;
public void processAction(ActionEvent event) {
if(userName.equals("sa") && password.equals("sa")){
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Login sucessfull."));
Exception
org.apache.jasper.JasperException: /registration.jsp(31,12) A literal value was specified for attribute actionListener that is defined as a deferred method with a return type of void. JSP.2.3.4 does not permit literal values in this case
at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)
Please can any one put some light in this problem..

I don't see anything wrong. The problem may be somewhere else, such as in the deployment or in the web.xml.
