We are in the process of writing a java client in ESB which would connect to PI environment ,in the past we had done using C# .net but which had limitation as it was just supporting windows platform. We used to connect PI SDK utility rest of the things SDK was managing.
Now we want it should support windows as well as in linux platform. So it should be developed in java and we need java API .
What do you suggest on which PI Developer Technology we should use.?
