Yes, the haarwavelet structure are actualy simple 2D filters. Filtering is implemented in OpenCV. Just look for the correct filter structure to get the desired result.
I only know the C++ - code but you can use Java bindings to reach the same result.

Just give filter2D a try, but looks like it can not implement the haar discrete wavelet transform.However, stack overflow do have an answer
