Orace Forms - ORA 1017 - Invalid username/password, logon denied

I am trying to call a form from the web with the following command:

https://test.com:7503/forms/frmservlet?config=webutil&form=xyz&userid=rajesh/test@mydatabase

It works fine.  However when I try to run the same command with a password containing special characters like:

https://test.com:7503/forms/frmservlet?config=webutil&form=xyz&userid=rajesh/test#123@mydatabase

I get the error:

ORA 1017 - Invalid username/password, logon denied.

I tried giving the password in double quotes but still getting the same error.  What is the solution for this?

Regards,

Rajesh
