JSF 2.0 Ajax Implementation

[Deniz Atak]

I am trying to solve this problem for days but couldn't find a proper solution. People suggested to use Ajax but I couldn't implement it. I had to open this thread because the other thread was not going any further and also the topic has changed.

I have a jspf page in which I am using facelets. I have a form with input values and a button. When user clicks on the button I want to check the validation and give user a feedback.

 <?xml version="1.0" encoding="UTF-8"?>
    <div class="rave-layout" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:webuijsf="http://www.sun.com/webui/webuijsf">
        <f:subview id="webfilteroverview">
            <webuijsf:form id="form1">
    <tr>
        <td>
            <webuijsf:label for="textField1" text="#{msg.reports_request_name}"/>
        </td>
        <td colspan="2">
            <webuijsf:textField binding="#{report.reportNameField}" columns="26" id="textField1" required="true"
                                style="margin-left:10px;" styleClass="textfield"/>                       
        </td>
    </tr>
    
    <h:commandButton value="push" action="#{report.submitReportRequest}">
            <f:ajax execute="@form1" render="@form1"/>
    </h:commandButton>

report.java:

  public void submitReportRequest() {
    if(reportNameField!=null){   
        submitted=true;
    }
    }

but it is giving:

PWC6143: No tag "ajax" defined in tag library associated with uri "http://java.sun.com/jsf/core"

error. However I am using JSF 2.0 and as far as I know JSF 2.0 has Ajax support included. What am I doing wrong?

Did you included all your libs?

[Deniz Atak]

I think the neccessary library is:

jsf-api.jar

it is under:
/home//netbeans-6.8/enterprise6/modules/ext/jsf-2_0/
/home/sges-v3/glassfish/modules/
