problem in getting already existing values

[madhuriks]

hi,
in my application i used jsp pages...the problem arises at modification...im using EL to get previous values that means already existing ones..im using 'disabled' concept for the text field i created but it is showing 'null' after i submit the form...if i check my XML...how to make it appear with the previous values.
