Olá pessoal,
Em um programinha de teste que estou fazendo, estou tendo um problema. O ActionForm parece não estar pegando os dados do jsp, retornando nulo. Acredito que fiz todas as “ligações” necessárias… mas ainda assim, retorna sempre nulo: não vê o que digito no text.
Coloco abaixo alguns trechos de arquivos importante pra solucionar o problema:
struts-config.xml, ao declarar o form-bean:
<form-bean name="addItemForm" type="com.edhand.example1.AddItemForm"/>
<form-bean name="delItemForm" type="com.edhand.example1.DelItemForm"/> struts-config.xml, no action-mappings:
<action path="/addItem" type="com.edhand.example1.AddItemAction"
name="addItemForm" scope="request" validate="true"
input="/pages/AddItem.jsp">
<forward name="success" path="/pages/Welcome.jsp"/>
<forward name="failure" path="/pages/erro.jsp" />
</action>
<action path="/delItem" type="com.edhand.example1.DelItemAction"
name="delItemForm" scope="request" validate="true"
input="/pages/DelItem.jsp">
<forward name="success" path="/pages/Welcome.jsp"/>
<forward name="failure" path="/pages/erro.jsp" />
</action> DelItemForm.java:
package com.edhand.example1;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
public class DelItemForm extends ActionForm {
private Long id;
public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request)
{
ActionErrors errors = new ActionErrors();
if (id == null)
{
errors.add("id", new ActionError("errors.required", "Código"));
}
return errors;
}
public void reset(ActionMapping mapping, HttpServletRequest request)
{
this.clear();
}
public Long getId()
{
return id;
}
public void clear()
{
this.id = null;
}
}DelItem.jsp

The taglib directive below imports the JSTL library. If you uncomment it,
you must also add the JSTL library to the project. The Add Library... action
on Libraries node in Projects view can be used to add the JSTL 1.1 library.

Percebam que acima tenho os beans addItemForm e delItemForm. O primeiro funciona perfeitamente, o segundo nao. Por isso coloquei os codigos soh dele.
Agradeço qq ajuda
