RE: ActionForm returning blank jsp
I have a blank page appearing when a null forward is returned.
How is your input page attribute in the validator form set?
May be Struts is trying to forward to a null forward so blank page
appears.

Subject: ActionForm returning blank jsp
I am having a problem with my ActionForm validate() method returning a
blank jsp page. It is a very simple logon.jsp with only two required
fields "username" and "Password" The ActionForm validates that the user
has in fact entered something in both fields. If the user has left a
field blank, the ActionForm should return an error, "please enter a
username", etc. All validation after that is performed in the
logonAction execute() such as "user not found in system", "invalid
username, password" etc. The LogonAction execute() returns errors to the
logon.jsp as it should. My logonForm however, does not, just a blank
(empty) jsp page. Any suggestions would be greatly appreciated.
Here is my JSP
<%@ page contentType="text/html;charset=iso-8859-1" language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %> <%@ taglib
uri="/WEB-INF/struts-bean.tld" prefix="bean" %> <%@ taglib

My STRUTS-CONFIG
My ActionForm
/**
* Form bean for the user signon page.
*/
public class LogonForm extends ActionForm {
private String password;
private String username;
public LogonForm(){
password = "";
username = "";
}
//getters and setters are here
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request)
{
ActionErrors errors = new ActionErrors();
if ((username == null) || (username.length() < 1))
errors.add("username", new ActionError("error.noUsername"));
if ((password == null) || (password.length() < 1))
errors.add("password", new ActionError("error.noPassword"));
return errors;
}

Yes, it is literally returning a blank document.
