A way to use Openssl in different languages/platforms

Openssl is known to be a standard in crypto world. Openssl is written in pure C, so the problem comes that how to use Opnessl in different languages? such Java. Though Java provides JCE and BouncyCastle, it's hard to know whether they have implementation deviations, i.e., for same input(legal or invalid), JCE and Openssl output different results.

What I come up with so far is to invoke openssl command directly. In real products, how to solve this problem?

Any help is really appreciated.
