Mochalua is a Java ME port of the Lua runtime and API.
Quotes from lua-users.org:
We were aware of Kahlua but it was incomplete when we started the Mochalua project (and may still be). We were also aware that there was another project locked within the bowels of a short-sighted company. So we put our money toward hiring a company, Nikitova, to work with us to do a conversion from scratch.
Mochalua is a port of the Lua runtime and API only, not the compiler. The API functions have kept their original names and signatures from the C implementation with only minor variations to account for language differences. It has been able to pass the Lua test vectors. We have also put it through its paces for our own projects. At this time, it should be a pretty stable codebase for you to use.
