DynaActionForm not working

Hi All,

I've created one form and trying to use dynamic form validation but instead any messages I'm getting "<ul><li></li></ul>".

In struts-config.xml

My AddressDynaAction class is as follows:

package dyna;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionMessage;
import org.apache.struts.action.DynaActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;

public class AddressDynaAction extends Action
{
  public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
    HttpServletResponse response) throws Exception{
 
    DynaActionForm addressForm = (DynaActionForm)form;
 
    //Create object of ActionMesssages
        ActionErrors errors = new ActionErrors();
    //Check and collect errors
        if(((String)addressForm.get("name")).equals("")) {
         errors.add("name",new ActionMessage("error.name.required"));
        }
 
        if(((String)addressForm.get("address")).equals("")) {
         errors.add("address",new ActionMessage("error.address.required"));
        }
 
        if(((String)addressForm.get("email")).equals("")) {
         errors.add("email",new ActionMessage("error.emailAddress.required"));
        }
    //Saves the error
    saveErrors(request,errors);
    //Forward the page
    if(errors.isEmpty()){
    return mapping.findForward("success");
    }else{
    return mapping.findForward("invalid");
    }
  }
}

My DynaAddress.jsp file is as follows:

<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
 
<html:html locale="true">
<head>
<title><bean:message key="welcome.title"/></title>
<html:base/>
</head>
<body bgcolor="white">
<html:form action="/DynaAddress.do" method="post">
 
<p>
<script language="javascript">
   var errors = '<html:errors/>';
   if(errors != '')
     alert(errors);
</script>
 
</p>
 
<table>
<tr>
<td align="center" colspan="2">
<font size="4">Please Enter the Following Details</font>
</tr>
<tr>
<td align="right">
Name
</td>
<td align="left">
<html:text property="name" size="30" maxlength="30"/>
</td>
</tr>
<tr>
<td align="right">
Address
</td>
<td align="left">
<html:text property="address" size="30" maxlength="30"/>
</td>
</tr>
 
<tr>
<td align="right">
E-mail address
</td>
<td align="left">
<html:text property="email" size="30" maxlength="30"/>
</td>
</tr>
 
<tr>
<td align="right">
<html:submit>Save</html:submit>
</td>
<td align="left">
<html:cancel>Cancel</html:cancel>
</td>
</tr>
</table>

</html:form>
</body>
</html:html>

Please help.

What's in your ApplicationResources.properties file? Do you have the following messages defined?

errors.invalid={0} is invalid.
errors.maxlength={0} can not be greater than {1} characters.
errors.minlength={0} can not be less than {1} characters.
errors.range={0} is not in the range {1} through {2}.
errors.required={0} is required.
errors.byte={0} must be an byte.
errors.date={0} is not a date.
errors.double={0} must be an double.
errors.float={0} must be an float.
errors.integer={0} must be an integer.
errors.long={0} must be an long.
errors.short={0} must be an short.
errors.creditcard={0} is not a valid credit card number.
errors.email={0} is an invalid e-mail address.

Did you define the validator plugin in your struts-config.xml file? Did you define validations in a validator.xml file?

For more details, read the Struts Validator Guide.

Also, if you're going to use JavaScript to display the errors (not recommended), you need to remove the errors.header, prefix, suffix, and footer.

My MessagesResource file is as follows:

# -- standard errors --
errors.header=<UL>
errors.prefix=<LI>
errors.suffix=</LI>
errors.footer=</UL>
# -- validator --
errors.invalid={0} is invalid.
errors.maxlength={0} can not be greater than {1} characters.
errors.minlength={0} can not be less than {1} characters.
errors.range={0} is not in the range {1} through {2}.
errors.required={0} is required.
errors.byte={0} must be an byte.
errors.date={0} is not a date.
errors.double={0} must be an double.
errors.float={0} must be an float.
errors.integer={0} must be an integer.
errors.long={0} must be an long.
errors.short={0} must be an short.
errors.creditcard={0} is not a valid credit card number.
errors.emailAddress=E-mail address
errors.name=Name
errors.address=Address
# -- other --
errors.cancel=Operation cancelled.
errors.detail={0}
errors.general=The process did not complete. Details should follow.
errors.token=Request could not be completed. Operation is not in sequence.
# -- welcome --
welcome.title=Struts Blank Application
welcome.heading=Welcome!
welcome.message=To get started on your own application, copy the struts-blank.war 
to a new WAR file using the name for your application. Place it in your container's "webapp" folder 
(or equivalent), and let your container auto-deploy the application. Edit the skeleton configuration files as needed, 
restart your container, and you are on your way! (You can find the application.properties file 
with this message in the /WEB-INF/src/java/resources folder.)
AddressForm.name=Name
AddressForm.address=Address
AddressForm.emailAddress=E-mail address
AdminForm.name=should be administrator

And one more question, do we've to define anything in validation.xml file for "Dynamic validation"?

All Struts Validation Framework validations are by definitinon "dynamic validations". You must define each validation you want performed in the validation.xml file. If you don't know how to do this, click on the link for the Struts Validation Guide that I gave you in my previous post, and read it.
