Put the text data in their own container tags. Also don't use <font> tags, they are deprecated in favor of stylesheets. Something like :
You were erroneously using the bean property 'firstName' to access the element of the DOM. You have got to realize that the server side constructs you are using have got nothing to do with the generated text. The user only gets the processed JSP file.
<jsp:useBean id="adminUser" class="bss.BSSUserDetailsDo" scope="session"/> <div style='font: normal 12px verdana; color: brown;'> <bean:message key="Bss.user.welcome"/> <span id='firstName'><jsp:getProperty name="adminUser" property="firstName"/></span> </div>

thanx for your response S.O.S.. i have made the changes as you told.
now when i try to access it and display on my page using " name.value " it displays "undefined". What i might have done wrong??
i saw my page source code after executing the page.. the source is some thing like this
where Tommy is the name i want to acces.Do you think its correct?

hay another thing..
this is a new thing which came with the change..
i made a function such that if the user types the same name as "Tommy" it should execute.
And the funny thing is as soon as i press "t" or "T" it gets executed.

innerHTML' property. Something like document.getElementById('firstName').innerHTML> And the funny thing is as soon as i press "t" or "T" it gets executed.
You need to show me the event handling code.
>
var a = document.getElementById('header');>
document.write(a.value);Again the same mistake. Access the inner HTML of a non-form element using the '
innerHTML' property. Something like alert(a.innerHTML). I don't accept change. I don't deserve to live.
