You really don't want to have 50 hibernate sessionfactories in memory. They are heavy to create. So as long as the schemas are the same use 1 sessionfactory and simply switch the datasource. Drawback is that you also would have to do something similair for 2nd level caching (switching caches also) but that shouldn't be a problem either. Mike,

The database side of this is exactly our situation and this is the approach that seems most reasonable to me. The implementation seems like a no brainer in straight JDBC, but we use hibernate, so I look forward to looking at your code. Another of our engineers advocates merging all the client databases into a single database and modifying the app accordingly. That sounds like a nightmare to me on several levels, including the risk to customer data. I have just started some prototype work on a branch of our application and look forward to letting you know how it goes. It is nice to stumble upon this!

Your article helped me to get the direction on this. The interceptor for the flows, "FlowSecurityInterceptor" is in the package: "org.springframework.webflow.security" . But in the spring-webflow jar I could not find the security package. Can you please help in knowing from where can I get the binaries for the same so that I can use in my application. Regards, Leena Hello sir,

In my application I’m trying to secure the web-flows using ACEGI. Your article helped me to get the direction on this.

The interceptor for the flows, “FlowSecurityInterceptor” is in the package:
“org.springframework.webflow.security” . But in the spring-webflow jar I could not find the security package.

Can you please help in knowing from where can I get the binaries for the same so that I can use in my application.
