Logon Page Customization in SAP Portal 7.31

Question

Hi Experts,
I am planning to change the look and feel of the Logon Page for Portal.
The current page is already a customized one.
For making the changes, I requested and got the following files.
1. tc~sec~ume~logon~ui.war from <drive>:\\usr\\sap\\<SID>\\J00\\j2ee\\cluster\\apps\\sap.com\\com.sap.security.core.logon\\servlet_jsp\\logon_ui_resources\\tc~sec~ume~logon~ui.war
and
2.  tc~sec~ume~logon~logic_api.jar from drive>:\usr\sap\<SID>\J00\j2ee\cluster\apps\sap.com\com.sap.security.core.logon\servlet_jsp\logon_app\root\WEB-INF\lib
The below is the screen shot of nwa/auth properties.
The file which was sent to me and the properties look like, standard logon module only.
I am not sure if the file is the custom one. How to find if its customized. In the layout folder, I couldn't fine any images in the current custom logon page.
I don't have access for deploying the ear. I have to send to the Server team and they only will be able to deploy.
Kindly advise me on how to proceed with.
Kind Regards,
Jelbin

here is the standard link for logon page customization for NW7.31 check it:
Developing a Custom Logon Screen - Developing Authentication Enhancements on the AS Java - SAP Library
if your are modifying a existing custom logon page first you will be requring the source code of that custom logon page ,Get it and import it in NWDS and follow the steps mentioned in standard help.
if source code is not available ask your server team to provide the custom logon page EAR file ,reverse engineer it by importing the EAR in NWDS and modify it as per your requirement and following the steps mentioned in help.
to know if you are modifying the correct EAR go to application.xml and check what is the application alias mentioned over there same will be configured in NWA under alias for application for login
as per your screenshot its mentioned as /new_logon
<context-root>new_logon</context-root>
Also check the J2EE engine .xml and check if you have your client name mentioned as company name.
Other check you can do id check images in the war file if those are present which are appearing on logon page when open,you can right click on image on opened portal logon page and get its name check in NWDS imported project war file if those images are present.you can do other chaecks in rendered code as per your customization to confirm if you are modiftyinfg the correct logon page ear or war file.
i guess if you dont have any the previous custom ear it might be under your provider location and application alias folder location not sure of it though :
<Installation drive>:\usr\sap\<SID>\J00\j2ee\cluster\apps\<providername>\com.sap.security.core.logon
\servlet_jsp\new_logon\tc~sec~ume~logon~ui.war
you can ask your server team if they found any war file in folder <provider name> or application alias folder or how many war file they found if they search with tc~sec~ume~logon~ui.war file ,aks them to give the one which is situated in your <client/provider.com > folder.
hope this helps.
