You can simply build the software yourself.

How to get the sources

You should have git installed

$ git clone git://

or you can download current sources as a zip file

How to build it

You need to have Maven installed

$ cd totp-me
$ mvn clean package

This default build uses Microemulator API implementation to simplify the build process, but it's only MIDP-2.0 implementation. To be sure the source code is MIDP-1.0 compatible, you should install Oracle WTK and provide path to it to Maven as wtk.home system property

$ mvn clean package -Dwtk.home=/opt/WTK2.5.2

How to run it in the Microemulator

Just use exec:java goal after you've successfully built the project

$ mvn exec:java
