Disabled field's value is reading as null

[anilareddy]

Hi friends,

I've got an error in my project.

<input type="text" name="empname" disabled value=<%=session.getAttribute("emp_name")%>>

and after submitting this,i'm trying to retrieve it as
String emp=request.getParameter(empname);

but it is reading it as null. If i remove the disabled attribute,it reads the value..
Can anyone tell me wats wrong in this and wat shud b done to correct it..
And one more error is that,if session.getAttribute("emp_name") is sachin tendulkar it displays only sachin and its leaving the remaining part except the first name. Please anyone suggest me

disabled fields are not submitted with their enabled siblings, which is why you get 'null' instead of ''.

Perhaps you should use readonly instead, which will be submitted but can't be changed by the user.
