Travel to Poland on a one way ticket

I would like to visit Poland next month, but plan to travel on to India after that. I want to visit Germany also before I leave. Will Poland allow me to enter with a one way ticket? They can but would they refuse me entrance on a one way ticket?

Thanks.

you wont be refused more than likely for that reason...

I came here on a one way ticket from the US two years ago and I've been here legally ever since. No problem.
