I am getting an error on this page when trying to do the example in the newsletter on Struts 1.1

Here is the error

Anyone know why I am getting this error? Does it really have to do with the LoginView.jsp? Or could the error be the result of another file?

Do you have your tld files defined in your web.xml? Are they in the right location?

Here's your problem:

In your web.xml, you define the URI as:
/WEB-INBF/struts-template
but you coded your JSP to use this URI:
/WEB-INBF/struts-template.tld
Those two have to be identical for it to work.

Ok, fixed that. But still getting the same error. Am I just stupid here?

Here is my LoginView.jsp page with the corrected URI's

BTW which editor you are using ??
I am using TextPad for jsp and Eclipse for Java.
TextPad shows different color[blue] for
<%@ taglib uri
and normal color[black] for
<%@ TAGLIB URI
you have to download plugin for jsp syntax coloring available at textpad.com

Well, good news. Thanks to Ravish and Thomas, I am not getting any errors.
BUT....
Now I am just getting a blank page.

I am starting to go bald because of this simple example.
I really don't know why it would be a blank page. I basically copy and pasted the code from the newsletter for the jsp page. Any ideas?

If you do "view source" what do you see?

There is a whole lot of Javascript but no actual FORM tags or plain html tags anywhere. And the <HTML> is never closed.

write one SOP just before forwarding string.
and make sure you have entry of that forward in your action.

Are you sure you have closing </HTML> tag in your JSP ??

The HTML is never closed because we forgot to put in a close HTML tag.

But that shouldn't screw anything up.
There should be a lot of JavaScript.
The question is why aren't the tags being turned into html.

I had caught that before posting the problem. So yes, I have the closing </html> tag.
Here is my file, again...

Is it supposed to be this hard?

If it was easy then anyone could do it! Minus the JavaScript, what does your source look like?

Hi Greg,
If you are getting a 'form bean null' error, the problem is probably with your struts-config.xml file. Make sure that your action definition has a name attribute containing the name of the dynaform you wish to use on the page.
Here is an example of how it should look like:

The 'name' is used to associate a form bean with a Struts action. If you don't define it, you will get 'form bean null' type errors.
Hope this helps.
Darryl

Well, I can't see anything wrong with my struts-config.xml, but here it is:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
          "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
 
<struts-config>

    <form-bean name="login"
           type="org.apache.struts.validator.DynaValidatorForm" >
      <form-property name="userId" type="java.lang.String" />
      <form-property name="passWord" type="java.lang.String" />
    </form-bean>

<action-mappings>
    <action
    path="/login"
    type="test.struts.LoginAction"
    name="login"
    input="/LoginView.jsp"
    validate="true">
    <forward name="valid" path="/MainMenu.jsp" />
    <forward name="invalid" path="/LoginView.jsp" />
</action>
  </action-mappings>

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

Hi there,
Sometimes when I get strange errors like this, I validate my web.xml and struts-config.xml files to make sure they are well-formed. It's happened to me on a number of occasions where the application loaded without error but didn't fully parse the configuration file because of errors in form.
Boy do I sound out of ideas, don't I? :-)

You and me both are out of ideas. So is there an easy way for me to validate my XML files?

is this class is in your classpath org.apache.struts.validator.DynaValidatorForm
I have not used this class but it seems that its not finding the class.
It seems that some class should extend this class. Do you have that class?
can you provide line num 97 of LoginView_jsp.java ?
You can find this file in work folder if you are using Tomcat with default setting.

You don't have a form-beans tag in your struts-config.xml!!!

one more NOTE:
xml files are also case sensitive.
I saw some tags in CAPS in your xml file.
just try making them small letters.

Line 97 reads

Ahh, then this is a typo on your part. You stated in your 1.1 newsletter article to change the struts-config.xml file to have the following:

I guess you left of the s??

thats what I was fearing ... this is almost last line of the generated code.
It does not help at all. Error is somewhere else not at line 97.

Ok, fixed the struts-config file to have <form-beans> instead of <form-bean> and still getting a blank page and a "Cannot retrieve definition for form bean login" in the error logs.
I really appreciate everyone that is helping me through this problem.

actually all <form-bean> tag should be inside <form-beans> tag.

No your strut-config.xml should be like this
