My understanding of .NET is that the EJB analogy
was the first part of .NET to be go production. When
.NET was first released it was called NGWS (next
generation windows services) and it included:
ASP+, ADO+, COM+. But when Windows 2000 shipped, COM+
was production quality while ASP+ and ADO+ were not
there yet.  Since then the Microsoft marketing department
renamed NGWS to .NET and renamed what was still
unreleased.  ASP+ became ASP.NET and ADO+ became
ADO.NET.  I'm not sure why they skipped GDI+.

Here is the translation table:

Enterprise ------------- J2EE ------------- .NET
Web Server Extensions - JSP/Servlet ------ ASP.NET
XML Web Services ------- WSDP ------------- Web Services
Transaction Monitor ---- EJB -------------- COM+
Database Integration --- JDBC ------------- ADO.NET

Java package -> .NET namespace
javax.servlet -> System.Web
javax.xml.rpc -> System.Web.Services
javax.ejb -> System.EnterpriseServices
javax.sql -> System.Data

So if System.EnterpriseServices is the EJB equivalent,
then it's just a matter of implementing that namespace
using a Linux CTM (Component Transaction Monitor).
