Customize Netweaver 7.3 Masthead (com.sap.portal.navigation.afp.masthead.war)

Hello Experts..

I am trying to customize Netweaver 7.3 Masthead file(Masthead.jsp) through NWDS. I have searched on SDN and found so many links but non of them resolve the issues.

Link:

http://scn.sap.com/thread/3265584

It says that we do not need to create EAR files for the Imported WAR file. I have followed exactly the same steps but after assigning needed JAR files to Lib folder and configuring Build Path, error didn't removed.

Does I am missing some thing here.

Link:

AFP - Masthead Modification

It says that we need to create EAR files for the uploaded WAR file. But needed Jar files are not said here.

My doubts are:

1. Do we need to create EAR file for the project in NWDS.

2. Which are the Needed JAR files required to remove the error of Project and Masthead.jsp file.

Can any one tell me the exact process to edit the Masthead and needed JAR files to remove the error....

If you guys have any document...Please share with us..It will be highly appreciated.

Please let me know...

Thanks.
