webpart

We have a large number of Java based servlets/portlets running in a BEA portal that we want to convert into SharePoint 2007 webparts. Many of the portlets use user preferences but the implementations are split between preferences being handled by the portlet directly and stored in a separate database from the portal. Others are using the BEA WebLogic API for user preferences.

Three questions:

Has anyone gotten a Java Servlet/JSP (compiled against JRE 1.4.2 and running on Tomcat 4.1) to run as a SharePoint 2007 webpart?
How large of an effort was it in general (as in, was it measured in days/weeks/months)?
Would it be easier to rewrite the portlet as native webparts at least as far as user preferences are concerned?
