Copyright text in Portal 7.3

Hello All,

I am trying to change the Copyright text in sap portal 7.3 to a client related Text.

I have changed the text in  LogonLabels.properties and LogonLabels_en.properties files.

And I have replaced the existing .war file with the customized one at server location and restarted the server.

But still the changes are not reflecting. Is there anything else that needs to be done. Am I missing something?

Kindly Reply ASAP. Thank you.

Regards,

Naveen
