Modify Alfresco Client like portlet on Liferay

[jackdaniels]

Hi all,
this is my first message in this forum.
I am an italian student and I'm working for a project where is required the integration between Liferay and Alfresco.
I've loaded Alfresco on Liferay like a portlet and now I can see the portlet Alfresco Client and use several features of Alfresco.
But I must modify the interface of Alfresco and adapt it for my web application.
How can I do it?
How can I create a personal web application on Alfresco deployed like portlet on Liferay?
Thanks for your help!!

Jack

I've begin to do somethings.
I've Alfresco.war that I've deployied on liferay. I've imported it on Eclipse like existing war project.
Here I'm customizing the file login.jsp to try some modify.
Is this the right way??
