disculpen lo extenso del mail, pero estoy empesando a ver un poco de struts 2 y tengo un problema que me impide continuar
estoy siguiendo un ejemplo del libro "struts 2 in action"
este es el jsp HelloWorld.jsp
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>HelloWorld</title>
</head>
<body>
<!-- The property struts tag reads the value off the value stack. In our case
the Struts 2 framework has automatically made the Java bean properties of
our action available to the result. We just need to match the nomenclature
of our value paramater below with the Java Beans attribute name of our
HelloWorld action.
-->
<hr>
<h3>Custom Greeting Page</h3>
<h4><s:property value="customGreeting"/></h4><br>
<h4><s:property value="customEdad"/></h4>
<hr>
</body>
</html>
----------------------------------------------------------------------------------
el atributo customGreetin lo muestra sin problemas pero customEdad no, tira el siguiente error:
GRAVE: ParametersInterceptor - [setParameters]: Unexpected Exception caught setting 'edad' on 'class manning.chapterTwo.HelloWorld: Error setting expression 'edad' with value '[Ljava.lang.String;@146e381'
les paso los siguientes archivos
NameCollector.jsp
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Name Collector</title>
</head>
<body>
<hr>
<h4>Enter your name so that we can customize a greeting just for you!</h4>
<s:form action="HelloWorld">
<s:textfield name="name" label="Your name"/>
<s:textfield name="edad" label="Your age"/>
<s:submit/>
</s:form>
<hr>
</body>
</html>
