Thanks. The pageContext.setAttribute() works!

This is not how you pass parameters from scriptlets to EL. EL typically
uses pageContext/request/session/application attributes. To make
anything but a String accessible via EL, you'll want to do
pageContext.setAttribute("db_fields", DB_FIELDS), or something like that.
By using the <c:set> tag, you are printing <%=DB_FIELDS%> and then
storing that as a page context attribute. In your example, try <c:out
value="${db_fields}" /> and you'll see what happens if you do
out.println(DB_FIELDS).
