Development

You can simply build the software yourself.

How to get the sources

You should have git installed

$ git clone git://github.com/kwart/totp-me.git

or you can download current sources as a zip file

How to build it

Download lcrypto-j2me-xxx.zip ("xxx" - current version of lcrypto, for example "lcrypto-j2me-156.zip") from the Bouncy Castle website and extract it to new lcrypto-j2me folder.

Copy folder totp-me/for-lcrypto-j2me/ contents to lcrypto-j2me folder.

Correct the lcrypto-j2me version number in pom.xml files

  • lcrypto-j2me/pom.xml: find <version>1.56</version>
  • totp-me/pom.xml: find <artifactId>lcrypto-j2me</artifactId> .. <version>1.56</version>

Install Maven.

Build and install lcrypto-j2me

$ cd lcrypto-j2me
$ mvn clean install

Build totp-me

$ 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
