Resource /j2ee/jsso/SSOLogin not found on this server

I was running three applications deployed on Oracle Application Server 10g Release 3 (10.1.3.1.0) because I got some errors I decided to undeployed two of them. Once I logged out and restart the SOA server using runstartupconsole.bat I am not able to get any more “Java SSO Login” web page which is launched using the url "http://<server>:8888/em".
Error got is:
--------------------------------
404 Not Found
Resource /j2ee/jsso/SSOLogin not found on this server
--------------------------------------------------------------------------
I assume that by mistake when those two instances where undeployed by supererogation I removed something related with “…\j2ee\home\applications\javasso” folder because after some research I found that this folder is empty therefore I made a copy of it from another server which are running an application exactly like this but even so I am not able to get around with this issue.
Please let me know if there is a way to get “Java SSO Login” web page
