We have successfully used IKVM to create a dlls for our Drools application.

The performance was a bit slower on IKVM/.Net as in Sun Java 5.
We dynamically load a large number of rules and found the largest impact is to the 'load time'

The performance impact was not such that it would make a network call viable; especially with 1000s of clients.

Apart from the performance impact the behaviour is exactly the same.

Hi all,

Suppose that you have a rule engine that needs to be embedded on the machine
and that there is no way to call the rules as a service from a centralized
server, what approach would one have to choose to make Drools and .NET work?

The rulke engine will have to be cached to improve performance, so that
part, until there is an up-to-date version of Drools.NET, has to be in Java
anyway. Then you expose your JAVA code as a (local) service and let .NET
call it? Or am I seeing things wrong here?

I must stipulate that I am not an expert in .NET at all, and I know only
barely enough Java to get Drools working :-). 

Thanks for your help.

Kind regards,
Frank

Hi,

I believe the .NET implementation of Drools is somewhat out dated.

However Drools ticks all your other requirements.

With kind regards,

We are looking for a rules engine that has the following
characteristics.



1.       Supports both Java and .net

2.       Provides a business user friendly UI for creating/editing rules

3.       Supports versioning

4.       The rues in the rules repository are accessible to both Java
and
.net applications – Nice to have



Do you know whether Drools supports all the above?



Thanks
