How to use different configurations?

[Marcelo Salhab Brogliato <ms...@vialink.com.br>]

Hi there,
my name is Marcelo and I'm new to the list. I use struts for some time  
and have some projects in it.
But I'm in a new situation now. My customer have two different  
business and he want the same application for both, but detached.
This application was developed with Struts2 and Spring (for dependency  
injection) and the core is the same for both business. It has just  
some different properties.
For example, main database (host, user, pass and schema), sync  
database (host, user, pass and schema) [our system communicates with  
another system throw an oracle database that we call sync database],  
and some minor preferences like application title, some default  
filters. All these settings are in a properties file for each customer.
How do I config struts to load these properties and use in my  
struts.xml? Is the interceptor a good way to put some of these  
properties in the ValueStack?
Do I need to deploy two times the same application, only changing the  
properties file? Or is there a way to dynamically select the correct  
for each http request?

I was thinking about creating a localhost.property, business1.property  
and business2.property. Creating a symbolic link to my  
localhost.property I could run the application on development server.
And in Ant I could create two targets, one for each business, and the  
only difference is which file they will copy (business1.property or  
business2.property).
Is there an easy way to do this?

Thanks for your help and time,
Salhab
