Verification failed on Username existence check using AJAX

Iam completely new to AJAX. Iam working on a web application using Struts, Spring and Hibernate. On the registeration page, there is button, on click of that it has to validate whether the username entered by the new user is already exists in the database( ms sql server 2005) or not.
But the problem is that AJAX is not getting called on the click of "Check Availability" button. I think there is some problem on URL. Because it is not able to enter into "" class since nothing is happening.

Following is my applicationContext.xml :-




The bolded line above in the code(register.jsp) has some problem i think because javascript alert "1" is not coming. But iam getting the alert "ein".
Please help me... I don't know what is happening inside actually and where i went wrong.
I would really appreciate your help.
Thanks in advance.

You posted quite the same question here too.

What is the first alert statement displaying?? Since you didn't provide the ID attribute for the text field, struts will generate a unique ID itself. You need to put the styleId attribute on the html:text tag to give it the ein ID. Also why are you using /*.do as the path to the server call?? And do you think this will call the AJAXCheckUserServlet servlet?? You've not declared the AJAXCheckUserServlet servlet in your web.xml, so it won't be called.
