[Mono-list] server-sided concepts in Mono / ASP.NET vs. Java EE

[Tobi Ulm]

Hi Kristian,

the current mono release 2.4 is somewhere between .net 2.0 and .net 3.5, but
it's not .net 3.0.

- we use the ressource assemblies for that.



- On the MS .net side there is the only "old" Application Server COM+ which
is being replaced some days. Right now there are two ways on the MS
plattform to host J2EE like apps. COM+ components (like beans, look under
System.EnterpriseServices. ServicedComponent; not supported in mono) and
Windows Communication Foundation (WCF, .net 3.0, not implemented in mono,
look at mono Olive). WCF is MS distributed Framework of the future, but the
only thing which is missing is an AppServer. So MS is working on an
Application Server for Windows and WCF, which codename is Dublin. in mono
there is, what i know, no Application Server where you can host .net
Components. Never used the spring framework.

- there are many ways for ORM in .net and mono. there is nhibernate, typed
datasets, LINQ to DataBases, EntityModel and a lot of others. But ORM is
sometimes not good:

- for Java <=> .net interop look for following:
