Struts em Ação, dúvida sobre o forward failure

Front-end
#1

Pessoal,

Estou começando no struts 1.3.8, e no primeiro não entendi o porque o meu forward “sucess” não funciona.

Tenho um formulário com três campos: usuário, senha e confirmação da senha, quando digitado usuário e submetido, o action checa se os dados conferem com um arquivo de properties. se Tudo correr bem, a página sucess.htm é exibida, caso contrário a página failure.html

O problema é que só a página failure.html é exibida indiferente dos dados que eu digite no formulário, gostaria de entender por que ocorre isto.

segue o meu fonte.

register.jsp

&lt;%@ taglib uri="/WEB-INF/struts-html.tld" prefix="form"%&gt; &lt;form:form action="register.do"&gt; Username:&lt;form:text property="username" /&gt; <br> Enter password:&lt;form:password property="password1" /&gt; <br> re-enter password:&lt;form:password property="password2" /&gt; <br> &lt;form:submit value="Register" /&gt; &lt;/form:form&gt;

success.html

[code]<html>
<head>
<meta http-equiv=“Content-Type” content=“text/html; charset=ISO-8859-1”>
<title>Sucess</title>
</head>
<body>
<center>Sucesso - Regsitration suceeded !

Try another?

</center> </body> </html>[/code]

failure.html

[code]<html>
<head>
<meta http-equiv=“Content-Type” content=“text/html; charset=ISO-8859-1”>
<title>failure</title>
</head>
<body>
<center>Falha - Regsitration suceeded !

Try again?

</center> </body> </html>[/code]

No struts-config.xml, você definiu como ‘success’, e na tua action definiu como ‘sucess’.

Obrigado pela resposta.

Eu entedi o que vc disse, mas como sou novato no struts não sei exatamente o que modificar pra funcionar…
