Ecommerce using stripes

[Ragav pb]

Hello All,

We have planned to start an e commerce project using Stripes + Hibernate.

Please let me know if it is good to have admin & user part in same project or two separate ones.
If it is a single project , how do i separate admin side code & user code.

for eg: if i have admin actions in com.ecommerce.adminactions pacakge and user actions in com.ecommerce.useractions package should i use dynamicmappingfilter to direct admin request to com.ecommerce.adminactions and user request to com.ecommerce.useractions ?

http://myecommerce.com/admin/* - > should always go to com.ecommerce.adminactions

http://myecommerce.com/ -> should go to com.ecommerce.useractions

or
Should i use @urlbinding(/admin/st.action) in each class (Hard code).

The requirement is they need multistore concept.
Please let me know your thoughts on this.Your thoughts & suggestions will be helpful
