how to integrate a functionality (implemented in java) in c# application

Hi,

I have implemented a c# application but now I have some new functionality (implemented in java) that I need to incorporate in my existing c# application. The java code itself is very big, so I don't want to write it again in c#. Instead, I am looking for a way to use that java code in my c# code. I came across some artilces that talked about JLCA, but I am not sure whether that would convert all the java code into c# code correctly. Any suggestions?
I will be highly grateful for your help.
