I am new to Struts and am using Ted's sample logon app as my basis for
learning. His part works fine. I added a new jsp page that contains two
fields, created a form bean & an action form with validation edits. My
problem is that when I execute my form via
http://localhost:8080/starrd/app/names.do I get validation errors appearing
immediately (before I enter any data in the form). I can't believe thats
normal: I must be doing something wrong.
Thanks in advance for the help.

Here's the pertinent parts of my struts-config:
<form-beans>
<form-bean
name="nameForm"
type="com.starrcs.app.SANameForm"/>
<global-forwards>
<forward
name="names"
path="/app/names.do"/>
<action-mappings>
<action
path="/app/names"
type="com.starrcs.app.SANameAction"
name="nameForm"
scope="request"
validate="true"
input="/pages/app/Name.jsp">
<forward
name="continue"
path="/pages/app/Name.jsp"/>
</action>
Here's my Name.jsp:
<!-- Name.jsp 2002/01/21 RJS -->
<%@ page language="java" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<html><head><title><bean:message key="app.name.title"/></title></head>
<html:base/>
<body>
<html:errors/>
<html:form action="/app/names" focus="name">
<table border="0" width="100%">
<tr><th align="right">Name:</th><td align="left">
<html:text property="name"/></td>
</tr>
<tr><th align="right">Address line one:</th><td align="left">
<html:text property="addr1"/></td>
<tr>
<td align="right"><html:submit property="submit" value="Submit"/></td>
<td align="left"><html:reset/></td>
</tr>
</table>
</html:form>
</body>
</html>

Here's the pertinent parts of SANameAction.java:
public final class SANameAction extends Action
{
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
// Obtain fields from web tier
String name = ((SANameForm) form).getName();
String addr1 = ((SANameForm) form).getAddr1();
// Log this event, if appropriate
if (servlet.getDebug() >= SAConstants.DEBUG)
{
StringBuffer message =
new StringBuffer("SANameAction: name = ");
message.append(name);
message.append(", addr1 = ");
message.append(addr1);
servlet.log(message.toString());
}
// Forward control to the welcome URI
// specified in the configuration.
return (mapping.findForward(SAConstants.WELCOME));
}
} // End SANameAction
Here's the pertinent parts of SANameForm.java:
public final class SANameForm extends ActionForm
{
// ---- Instance Variables
private String name = null;
private String addr1 = null;
// ---- Properties
public String getName()
{
return (this.name);
}
public void setName(String name)
{
this.name = name;
}
public String getAddr1()
{
return (this.addr1);
}
public void setAddr1(String addr1)
{
this.addr1 = addr1;
}
// ---- Public Methods
public void reset(ActionMapping mapping,
HttpServletRequest request)
{
setName(null);
setAddr1(null);
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{
ActionErrors errors = new ActionErrors();
if ((name == null) || (name.length() < 1))
errors.add("name",
new ActionError("app.error.name.required"));
if ((addr1 == null) || (addr1.length() < 1))
errors.add("addr1",
new ActionError("app.error.addr1.required"));
return errors;
}
} // End SANameForm
When I first execute the form via http://localhost:8080/starrd/app/names.do
I immediately (before entering any data or executing the submit button) I
get validation errors displayed for name and addr1 and get the following in
my log file:
2002-01-21 20:19:19 action: Processing a GET for /app/names
2002-01-21 20:19:19 action: Looking for ActionForm bean under attribute
'nameForm'
2002-01-21 20:19:19 action: Creating new ActionForm instance of class
'com.starrcs.app.SANameForm'
2002-01-21 20:19:19 action: Storing instance under attribute 'nameForm' in

2002-01-21 20:19:19 action: Populating bean properties from this request
2002-01-21 20:19:19 action: Validating input form properties
2002-01-21 20:19:19 action: Validation error(s), redirecting to:
/pages/app/Name.jsp
Then if I fill in the two fields with data, I do not get validation errors
(which is correct). Then this is what is in my log:
2002-01-21 20:19:37 action: Processing a POST for /app/names
