Question

I’m creating createEdit.jsp , the page which can handle both edit and create new users.
Here is my jstl tag

<c:if test="${ pageAction == 'edit' }"> 
<input type="text" name="loginU" disabled="disabled" value="${userEdit.login}"/>
</c:if>

if this page is ‘edit’ I have disabled textfield with login (e.g. ‘user’ ) shown.
The problem is – this value can’t be posted further as request expires.
And When I’m trying to get loginU on my servlet I get null.

String loginU = req.getParameter("loginU");

out.println("login: " + loginU);

What should I do to pass this ${userEdit.login} further

Answer 1

inputs marked as disabled do not get POSTed, ones marked as readonly do however, so you could:

<c:if test="${ pageAction == 'edit' }"> 
    <input type="text" name="loginU" readonly="readonly" value="${userEdit.login}"/>
</c:if>

The alternative, which may look better, is to spit the value out and add a hidden input to send the value:

<c:if test="${ pageAction == 'edit' }">
    <p>${userEdit.login}</p> 
    <input type="hidden" name="loginU" value="${userEdit.login}"/>
</c:if>
