OO Calc in Business Layer for Enterprise Application

[nordmeyer]

Hi,
I am want to use Calc to implement business logic for a JEE application. Best I would like to embedd Calc in my Java Process but I can't find anything about this architecture. Therefore I think I have to access running Calc processes from my Java Process. To be able to serve multiple requests parallely I think I have to run multiple Calc processes on the same Computer. Am I right?

Mabe someone has a hint for a better solution or can point me on mistakes in my approach.

Thanks in advance.

CU,
Thomas
