Multiple web apps deployed on separate tomcat server with a single access homepage?

An old fashioned way to do it would be to keep a top frame from your menu app, and use the lower portion for the other apps, but it's not recommended. Apache tiles lets you integrate page fragments, like the top menu, which you could synchronize to various servers with a rsync script. Another possibility, would be to ask the fragment from the central server using an AJAX call with JSONP, to overcome the cross domain limit.

I suspect that since the apps are already developed it's too late for this fourth possibility, but the cleanest way to develop an app now, is writing a platform API, accessible with AJAX calls. To clarify: Apart from integrating the layout, do you also want to have a common login? Why do you reject portal technology?

Thanks for your suggestions. Yes, there's single sign-on as well. I don't reject the portal technology at all, I am interested to know about other ways before going into portal and trying to keep the learning curve low for the team.

Would portals like Liferay or Spring portlet do it easily? – Smith James Oct 28 at 13:41.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
