null to empty string

i was wondering if JSP has something like converting all null String into

an empty string to be display on the page input fields

currently, i have to do something like

public String emptyString(String s){

return (s ==null)?"": s;

}

i was hoping JSP have something that will do this automatically for you..

# 1

Say for request.getParameter("userName")

<%= (request.getParameter("userName") == null)? "": request.getParameter("userName") %>

If you are using JSTL the c:out tag has a default value that you could set to a blank string.

Or you could create your own custom tag to do the same thing.
