cannot sete debug mode in client side code

[peter tong]

I am using Oracle Enterprise Pack for Eclipse,

I can set breakpoint in server side code but cannot debug in client side code, my run/debug configuration, Arguments tab > Program arguments is as follow:
Run/Debug Settings
-remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -startupUrl http://127.0.0.1:7001/ALS.html -logLevel INFO -noserver -codeServerPort 9997 -war D:\workspace\ALS_AdministrationConsole\war com.ha.als.ALS

my server is in localhost (but not using gwt jetty, I use oracle in localhost)
In IE, if I double click the url
url
will display
Error 404 -not found
if enter the url
url2
the application can be run, but not in client side debug mode.
what wrong with the program arguments in the debug mode for client side debugging fail?
