.net calling java, for the 100th time

[c]

So far it looks like we have these options for calling our java based API
from a .NET application:

1) http://www.jnbridge.com, about $500 per machine/developer
2) re-write java app in Visual J++ (Microsoft java) - then it will
integrate nicely with .NET.
3) use web services
4) use JNI

Option 2 isn't possible, because our java based app is a huge server side
beast. Not sure how the JNI option would work. Our product doesn't support
web services yet, so option 3 is out.

Did I miss anything?

thanks.

I think there are many Java-COM bridges out there; .NET can play with COM
components nicely, so that could be a good way to go.
But the answer really depends on what you want to do: Any kind of
IPC/component technology could solve your problem: sockets, CORBA, memory
mapped files (not sure if java has native support for those)

perhaps this article will help.

Just because your application doesn't support web services (yet), how is #3
out?
You can add web services to the Java side, and call them from the .NET side.
What's so bad about that?

Or, you could create a set of facade classes that call your Java app, and
compile those classes in Visual J# (Java syntax), and make them available as
web services or COM components. That is probably the easiest way.

Concur with Nick's Option 1 because it is the most decoupled.
Option 2 ties the solution to J++ and COM, both Windows only technologies.

Hey folks --

JNBridgePro isn't that expensive. You can deploy it for $95/machine for the
SE version. That's for each .NET machine on which our components reside;
you can deploy the Java components on as you want. There are also volume
discounts. See http://www.jnbridge.com/pricing.htm for more information.

The development license is indeed $495 for one developer seat, but you
likely only need one developer license.

Compared to the developer time needed to roll your own .NET/Java interop
solution, JNBridgePro is a good deal.
