struts appliation problem on WAS 5.1.1

It seems that struts encountered problem initilise the plugin, what plugin are you configured in the struts-config.xml?
Check whether the files used by the plugin exist and are in the correct path.

Here's my struts-config.xml
<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
          "struts-config_1_1.dtd">


<struts-config>
 
  <form-beans>
      <form-bean name="PinForm" type="xx.yy.zz.pinrequest.form.PinForm"/>
      
 </form-beans>
 
 <action-mappings>
   <action path="/pin" type="xx.yy.zz.pinrequest.action.PinAction" name="PinForm"
            scope="request" input="/pin.jsp" validate="true">
             <forward name="pin" path="/pin.jsp" />
   </action>
 </action-mappings>

 <message-resources
     parameter="resources.ApplicationResources"
     null="false" />


 <!-- Validator Configuration -->
<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>

What should I do when you said I should put mu plugin in right path

The value for the attribute should be on the same line.
This is because xml parser will not remove the "\n" from the value when it read the struts-config.xml.

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

However, you can set the path to multiple lines coz the plugin will split the value using the delimeter ",".
  <set-property property="pathnames"
               value="/WEB-INF/validator-rules.xml,
                          /WEB-INF/validation.xml"/>

Thank you very much ..I don't see that error any more but I don't see the validation  error message  displayed when I enter 999999999 or 000000000 for ssn.
I see the following message in logs:

364d4e6c PropertyMessa I org.apache.struts.util.PropertyMessageResources  Initializing, config='org.apache.struts.taglib.html.LocalStrings', returnNull=true

In my jsp I have 3 passowrd fields with properties SSN1,SSn2,SSN3
I added  <html:errors property="ssn"/> to my jsp just below my <html:html>

here is my action:

package xx.yy.zz.pinrequest.action;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Iterator;
import java.util.List;

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


import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.Action;
import us.ny.state.otda.dcse.pinrequest.form.PinForm;

public class PinAction extends Action
{

   public ActionForward execute(ActionMapping mapping, ActionForm form,  HttpServletRequest request,  HttpServletResponse response)
        throws Exception
      {
              ActionErrors errors = new ActionErrors();
                 
             PinForm pinForm = (PinForm) form;
       boolean ssnValidity = true;
          String ssn = pinForm.getSSN();

         /**  PinBD pinBD=nul;
             pinBD=new PinBD();

            String valid= pinBD.getSSN(ssn);
            String mesg=pinBD.getResponseMessage();*/
            
             
            try
            {
                               if(ssn.equals( "000000000") || ssn.equals ("999999999"))
                    {
                                ssnValidity = false;
                }
            }catch(Exception e){
             errors.add("ssn", new ActionError("error.invalidSsn.errorMsg"));
                  saveErrors(request,errors);
                  return mapping.findForward("pin");
              }
           return mapping.findForward("pin");
      }
      
  }  
             

Mu config.xml is above in yesterdays' comment and my ApplicationResources is below
 
        error.invalidSsn.errorMsg= Please enter a valid SSN.
  error.noRecordFound.errorMsg= No record found for this SSN.
   
 
 
 
 # Struts Validator Error Messages
   errors.required={0} is required.
   errors.minlength={0} can not be less than {1} characters.
   errors.maxlength={0} can not be greater than {1} characters.
   errors.invalid={0} is invalid.

   errors.byte={0} must be a byte.
   errors.short={0} must be a short.
   errors.integer={0} must be an integer.
   errors.long={0} must be a long.
   errors.float={0} must be a float.
   errors.double={0} must be a double.

   errors.date={0} is not a date.
   errors.range={0} is not in the range {1} through {2}.
   errors.creditcard={0} is an invalid credit card number.
   errors.email={0} is an invalid e-mail address.


Since I'm doing validation in action I guess  I don't need to worry about validation.xml         

Thbaks a lot for the earlier anwser and please let me know what I'm doing wrong here.    

I'm getting below error when I put my validation in my form.
Error 500: Server caught unhandled exception from servlet [action]: null

I also changed my validation.xml and added   pinForm.ssn1 =SSN1 to applicationproperties

my validation.xml islike this now

<form-validation>
  <formset>
    <form name="PinForm">
      <field property="ssn1"
            depends="required">
        <arg0 key="pinForm.ssn1  "/>
      </field>
     </form>
   </formset>
 </form-validation>

and my validation in form is as follows:

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
      {
       
            ssn=getSSN();
             System.out.println("1:"+ssn);    
        ActionErrors errors = new ActionErrors();
       errors = super.validate(mapping,request);
       System.out.println("hello1");
      System.out.println("2:"+getSSN());
        if(this.getSSN().equals( "000000000") ||  this.getSSN().equals ("999999999"))
          {
                                System.out.println("hello2");
                   // errors.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("error.invalidSsn.errorMsg"));
                      errors.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("pinForm.ssn1 "));
                        
                                System.out.println("hello3");
               
          }
          return errors;
      }

I'm so confused.

Hmm... the codes looks fine.
Can you post the entire error stack trace.

In Action stack trace do you notice 'config='org.apache.struts.taglib.html.LocalStrings', returnNull=true'
Does that mean something
