Problem using JDEbug, couldn't debug a simple HelloWorld Program

[Sumeet_Singh]

Hi,

I'm having problems in JDEbug feature of JDE. After the first breakpoint is
hit, and I hit "continue", the Debugger Hangs, and I get a timout errors
thereafter. I looked the FAQ and changed the jde-bug-raise-frame-p variable
to "off". Still getting the error. Please help.

The details are :
     host platform : Solaris 2.6
     JDE version : JDE 2.0In GNU Emacs 20.4.1 (sparc-sun-solaris2.6, X
     toolkit) of Wed Oct  4 2000 on mars
               configured using `configure  --prefix=/u/ssingh2/emacs'
     Emacs version : Emacs 20.4.1
     Content of my .emacs file :
;; This .emacs file illustrates the minimul setup
;; required to run the JDE.

;; Set the debug option to enable a backtrace when a
;; problem occurs.
(setq debug-on-error t)

;; Update the Emacs load-path to include the path to
;; the JDE and its require packages. This code assumes
;; that you have installed the packages in the emacs/site
;; subdirectory of your home directory.
;; added for JDE

;; If you want Emacs to defer loading the JDE until you open a
;; Java file, edit the following line
(setq defer-loading-jde nil)
;; to read:

;;  (setq defer-loading-jde t)
