How to run helloworld portlet in Pluto 2

Hi all,

I am a new bee in Portlet and I just want to have taste of what actually it is, So I decided to learn Portlets but as I started I am getting confused in pluto version.
The book I refer uses pluto 1.1 and requires maven task to first create with source and make pluto run. I downloaded installable version 2 of pluto Its running in tomcat but as I open the basic URL http://localhost:8080/pluto/portal Its giving a blank page Document says enter username password but Its a blank page I don'y know where to enter. When I try to open the tomcat manager It gives some 401 error page( I figured out that manager app is not installed properly in that download). I am unable to run a basic programme in 2 days

.

So Please help me getting out of it

and suggest me a basic helloworld tutorial in pluto 2 so that I could start from there also any book that could take me further.

Thanks in Advance.
