Sridhar,
JDE looks for a prj.el in your current directory and if it does not find one
looks in the parent directory, etc. Therefore if you have different prj.els
it will use the appropriate one from your path and switch automatically.

PS.
Alternatively you could use an over-the-top function like make-ibm117 below
to reset your variable names. Here's how I did it.
; UNIX or NT?
(defconst running-x (eq window-system 'x))
(defconst running-win32 (equal (device-type) 'mswindows))
;; Where am I at the moment?
(cond (running-win32
;; evaluates to 0 if found!
(defconst at-home (string-match "JCOOLEY" (getenv "COMPUTERNAME")))
(defconst at-jcp (string-match "JAMESC" (getenv "COMPUTERNAME")))
(cond (at-home (setenv "JAVAHOME" "h:\\utils\\ibm1.1.7"))
(at-jcp (setenv "JAVAHOME" "C:\\utils\\ibm\\jdk1.1.7")))
;; Bash setup on NT
(setq explicit-shell-file-name "bash")
(setq explicit-sh-args '("-login" "-i"))
))
(defun make-ibm117 ()
"Set up IBM JDK1.1.7 environment"
(interactive)
;; just need to upadre the CLASSPATH
