SharePoint and Web applications

[kensington]

We currently use Windows server for hosting ColdFusion and JSP.
We will be getting SharePoint next year. I assume we can still link our ColdFusion and JSP applications to SharePoint with just basic links?
Also it looks like anybody can create web pages with SharePoint but what if you need to create a Web Application with database backend? Would we have to learn .Net to do advance web applications in SharePoint?

Any page published by sharepoint is just like any other page and will have a url that can be used to link to it, just like any other page on the internet.

With regards to data access Sharepoint has it's own infrastructure that can remove a lot of the coding required with asp.net / ado.net, if you are looking at data access with sharepoint you will want to investigate the built in web parts, data sources and the Business Data Catalog (BDC) for starters.
