how do struts and ejb combine to a web application

I use struts to develop a web application.
Homepage's URL is http://www.aaaaa.com/web/aaa.do
But our client hope when they type www.aaaa.com, page that IE shows is same as page that is http://www.aaaaa.com/web/aaa.do
Please ask how to solve. Thank you reading and help!

I have code that is related to connection pool.
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/myoracle");
conn = ds.getConnection();
Many of struts's action need call it.
I know 2 ways.
1) Codes is written in every action that use it.
2) encapsulating code into one class's static method.then every action class all call the class'static method
using 1), I fell CODE is redundancy!
using 2), when many user access application,if encapsulating class is single thread, performance will be bad.
or,if I have other choice?
Thanks
[note]: Basically I Don't intend to use mutiple-tie structure,so I directly wirte sql into action class

Hi,firstly, thank for your reply.
In fact , I know what you said. What I really want to know is as below:
Example:
how many lay should ejb be divided into? How is these lay's relation each other? Have such example?

I want to use struts Framework for web lay , then I want to know which Framework I should use for Ejb that belongs business lay.
Thanks very much!

I feel difference is if method ejbCreate'parameter can be saved。
is it right?
besides it, has other difference?

1.A session bean(bean1)'s method, with Required Attibute of Transaction
2. it call a entity bean's setXX("")(ex:setAccount(""))
3.call bea1.remove(),then happens the error,as if is not successful in Step 2.
4.when i switch the Required attribute to Support in Step 1, and it Did!
why?
Thanks a lot.
