You may give javaocr a try ( http://sourceforge.net/projects/javaocr/ , yes, I'm developer )
Therre is no offocial release though, and you will have to look for sources ( good news: there is working android sample including sampler, offline trainer and recognizer application )
If you only one font, you can get pretty good results with it (I reached up to recognition rates 99.96 on digits of the same font)
PS: it is pure java and uses invariant moments to perform matching ( so no problems with scaling and rotation ) . There is also pretty effective binarisation.
