Ola amigos, vejam se entendem o problema

Porque quando eu passo o mouse sobre o botão ele não me manda uma msg na tela?

Att

Criei um form teste com os seguintes codigos abaixo :

jsp:

[code]<?xml version="1.0" encoding="UTF-8"?>

<jsp:root version=“2.1” xmlns:f=“http://java.sun.com/jsf/core” xmlns:h=“http://java.sun.com/jsf/html” xmlns:jsp=“http://java.sun.com/JSP/Page” xmlns:webuijsf=“http://www.sun.com/webui/webuijsf”>

Tá com cara de q vc está usando o editor visual de JSF do Netbeans. Eu trabalho com JSF a algum tempo e te aconselho a não usar essa ferramenta, especialmente se vc
ainda está aprendendo JSF.
Outra coisa, JOptionPane é um componente da SWING, q é uma API p/ desenvolver sistemas de desktop não sistemas WEB.

Ok, entao como posso mandar ums msg na tela ?

Ao passar o mouse em cima do botão ?..

Vc pode usar a funcão “alert” do JavaScript.

Ok usarei ele, mas como ? como declaro este alert no evento ?

Obrigado!

Kra o atributo onMouseMove não pode ser usado do modo q vc usou no seu código. Ele serve apenas p/ executar script. Tente isso:

<webuijsf:button id="button1" onMouseMove="#alert('Hello user!:)')" style="position: absolute; left: 240px; top: 312px" text="Botão"/>
