Customizing Logon Page in Portal 7.4

Hi,

I need to change the branding image of portal (7.4).

I got the below War and Jar 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

When I imported the war file into NWDS, I am getting the build errors. I added the required jar file to the WEB-INF folder and to the Build Path. But still I have build errors.

I also refered the below docs.
