RE: Validation Problem

[Bailey, Shane C.]

I didn't notice if you got your problem solved but it is a simple spelling
error:

   public void setField1(String feld1)
   {
    this.field1 = field1;
   }

should be:

setField1(String field1)

Subject: Validation Problem

Hi!

I now have a strange validation problem. I use this ActionForm class:

package com.mycompany;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionServlet;
import org.apache.struts.util.MessageResources;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import java.lang.String;

public class PostTestForm extends ActionForm
{
   private String field1 = "";
   private String field2 = "";
   private String field3 = "";

   private void checkForEmpty(String fieldName, String fieldKey, String
value,
                              ActionErrors errors)
   {
    if (value.trim().length() == 0)
    {
     System.out.println(fieldName + value.trim().length());
     ActionError error = new ActionError("error.posttest.field.null",
fieldName);
     errors.add(fieldKey, error);
    }
   }

   private void checkForLength(String fieldName, String fieldKey, String
value,
                               int maxLength, ActionErrors errors)
   {
    if (value.length() > maxLength)
    {
     ActionError error =  new ActionError("error.posttest.field.length",
fieldName);
     System.out.println(maxLength);
     errors.add(fieldKey, error);
    }
   }


   public ActionErrors validate(ActionMapping mapping,
     HttpServletRequest request)
   {
    ActionErrors errors = new ActionErrors();

    checkForEmpty("field1", "error.field1.empty", getField1(), errors);
    checkForEmpty("field2", "error.field2.empty", getField2(), errors);
    checkForEmpty("field3", "error.field3.empty", getField3(), errors);

    checkForLength("field1", "error.field1.length", getField1(), 5, errors);
    checkForLength("field2", "error.field2.length", getField2(), 5, errors);
    checkForLength("field3", "error.field3.length", getField3(), 5, errors);

    return errors;
   }

   public void reset(ActionMapping mapping, HttpServletRequest request)
   {
    field1 = "";
    field2 = "";
    field3 = "";
   }

   public String getField1()
   {
    return field1;
   }

   public void setField1(String feld1)
   {
    this.field1 = field1;
   }

   public String getField2()
   {
    return field2;
   }

   public void setField2(String field2)
   {
    this.field2 = field2;
   }

   public String getField3()
   {
    return field3;
   }

   public void setField3(String field3)
   {
    this.field3 = field3;
   }

}

Everything works fine except the application always claims, that field1 is
empty
even if it's not. value.trim().length() always is = 0 with respect to the
field1.
The content of the HTML-Form looks like this:

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<html:form action="postTest">
<table border="0" cellpadding="0" cellspacing="0"
style="border-collapse:collapse" bgcolor="E7E7E7" width="100%"
height="900px">
<tr>
  <td>
    <html:errors/>
  </td>
</tr>
<tr>
  <td>
    <input name="field1" type="text" size="17" maxlength="32">
  </td>
</tr>
<tr>
  <td>
    <input name="field2" type="text" size="17" maxlength="32">
  </td>
</tr>
<tr>
  <td>
    <input name="field3" type="text" size="17" maxlength="32">
  </td>
</tr>
<tr>
  <td>
    <input name="submit" type="submit" value="Submit">
  </td>
</tr>
</table>
</html:form>

What's wrong???

Regards
Tom
