[Peter L. Berghold]

Hi folks,

I’ve been pounding my head against the desk trying to figure this one out on my own and from all the documentation I’ve read this
thing should just work but it doesn’t.

Here is a JSP form:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles"%>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>





<html:form action="/actions/public/system/sendEmail" method="POST"  onsubmit="return validateSendEmailForm(this);">
<html:javascript formName="sendEmailForm"/>
    <p>
        Use this form to send an email. All fields are considered mandatory.
        Email addresses will be checked for validity.
    </p>
    <p>
        Please be sure to include your real name in the body of the message to
        avoid confusion on the part of the email recipient
    </p>
    <p style="border: 1px; color: red; ">
        <html:errors /> 

    </p>
    <hr>
    <table width="100%">
        <tr height="30">
            <td width="30%" align="right">
                From:
                <br>
                (Your email address)
            </td>
            <td>
                <html:text property="from_rq" size="40" maxlength="80" />
                <br>
                <html:errors property="label.from_rq" />
            </td>
        </tr>
        <tr height="30">
            <td width="30%" align="right">
                Subject:
            </td>
            <td>
                <html:text property="subject_rq" size="40" maxlength="72" />
                <br>
                <html:errors property="subject_rq" />
            </td>
        </tr>
        <tr>
            <td width="30%" align="right">
                Message body:
            </td>
            <td>
                <html:textarea property="body_rq" rows="10" cols="40" />
                <br>
                <html:errors property="body_rq" />
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <table width="100%">
                    <tr>
                        <td width="33%">
                        
                            <html:cancel value="abort" property="action_rq" />
                        </td>
                        <td width="34%">
                             
                        </td>
                        <td>
                            <html:submit value="Send" property="action_rq"></html:submit>
                        </td>
                    </tr>
                </table>
            </td>
        </tr>
    </table>

</html:form>

The form bean itself looks like this:

and here is the whole mess referenced in the struts-config.xml file.

<form-bean name="sendEmailForm"
            type="org.bcdc.struts.form.SendEmailForm" />
<!-- other stuff between here and there -->
        <action
      attribute="sendEmailForm"
      input=".public.email.send"
      name="sendEmailForm"
      path="/actions/public/system/sendEmail"
      scope="request"
      validate="yes"
      type="org.bcdc.struts.action.SendEmailAction">
      <forward name="class_detail" path="/actions/public/class/detail.do" />
      <forward name="failure" path="/actions/public/sendEmail.do" />
    </action>
<!-- and here is the validation framework being invoked --> 
    <message-resources parameter="org.bcdc.struts.ApplicationResources" />
    <plug-in className="org.apache.struts.tiles.TilesPlugin">

        <!-- Path to XML definition file -->
        <set-property property="definitions-config"
            value="/WEB-INF/tiles-defs.xml" />
        <!-- Set Module-awareness to true -->
        <set-property property="moduleAware" value="true" />
    </plug-in>

    <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
        <set-property property="pathnames"
            value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />
    </plug-in>

And here is the validation ruleset for this form:

 <form name="sendEmailForm">
      <field property="from_rq" depends="required,email">
          <arg0 key="label.from_rq"/>
      </field>
      <field property="subject_rq" depends="required">
          <arg0 key="label.subject_rq"/>
          
      </field>
      <field property="body_rq" depends="required">
          <arg0 key="label.body_rq"/>
      </field>
  </form>
  

The ultimate goal here is to process all this server side, but I enabled the javascript stuff in an attempt to narrow down what is going
on.

What I’m seeing is if I invoke the form and hit submit, instead of seeing the errors that I’d expect I’m getting a blank popup. This
would IMHO indicate that the validation framework is doing its thing, but cannot find my message library. The message library
ApplicationResources.properties is right where I’d expect it to be and here is what is in there:

# Resources for parameter 'org.bcdc.struts.ApplicationResources'
# Project P/www.bayshoredogclub.org

label.from_rq=Your Email address
label.subject_rq=Subject
label.body_rq=A body of message text

The only thing I can’t seem to figure out is why it can’t find the messages…

Peter, don’t forget to double check with the Struts folks on this as well. I don’t know off hand (never used the validation framework) but I’ll ask another guy in the office that might to see if he knows. If he doesn’t (or is too busy) he many not reply though.
