Customized login page

Hi,

I copied the sap provided logon.par file and changed the umlogon.jsp file (just removed the branding images). I created an iView and embedded it in the anonymous access page. It works fine with login.

However the login error messages return back to the original login page. Kindly let me know how to return the error messages to the calling page.

Thank you in advance.

Rgds,

Janvi.
