    <tiles:putAttribute name="body">  
        olá mundo!

e o template:

    <body>
        <h1>TEMPLATE</h1>        
        <div id="divContent">  
            <tiles:insertAttribute name="body"/>  
        </div>          
    </body>
</html>

O que pode ser?

não conheço quase nada de tiles… mas parece algum erro no formulario.jsp, ou no template que se aplica nele… ve se não tem alguma conf feita errado.

de onde vc copiou esse código? tá com o filtro do tiles configurado direitinho? dá algum erro no startup da aplicação?

hugohmesquita 13 de nov. de 2012

rapaz mudei do tomcat para o glassfish ai deu certo… logo em seguida voltei para o tomcat e funcionou :shock:

Lucas_Cavalcanti 13 de nov. de 2012

pois eh… geralmente a primeira solução pra problemas bizarros é dar um clean no projeto e no servidor… às vezes fica algum lixo lá.
