How to display popup in JSF

How to display popup on click of some button on the jsp?

do you know how to open a pop-up on HTML?

No I have not used Html popup even previously.

just google this topic, doesn't have to include JSF in your google search unless you need specific JSF functionality

Ok Thanks

                                        value="OpenPopup"/>
                </rich:panel>
            </h:form>
        </body>
    </html>
</f:view>

Before run this code, Just create sample jsp page (sample.jsp).
Both program (mainPage.jsp and sample.jsp) you will maintain same location.
