I hope someone can help clarify building webparts: As I understand it, you can create a webpart in any of the supported .NET languages. This would include J#, but not Sun's Java. Further, you can't have JSP as webparts. Is this correct or are there exceptions?

Also, has anyone been successful in creating a webpart with J#? Or know of any webpart J# sample code we could download to look at?

We are mostly a Java shop and want some idea of what it would take for our programmers to develop webparts using J# rather then C# or VB.
