oSCJ

Open Safety Critical Java (oSCJ) project implements a restricted subset of SCJ (JSR-302). The project is developed at S3 group at Purdue University.

For more information, see the oSCJ webpage: http://www.ovmj.net/oscj/

Check-out oSCJ

You can check-out oSCJ from our Mercurial repository: hg clone https://scj-jsr302.googlecode.com/hg/ scj

Check-out oSCJ's VM

oSCJ library can be executed on top of two different Virtual Machines : FijiVM and Ovm.

• FijiVM - FijiVM is available under academic license, feel free to directly contact us to obtain its distribution. FijiVM' usage is surprisingly simple and while delivering astonishing performance! (See FijiVM Installation instructions: http://rtjava.blogspot.com/2010/10/oscj-news.html) ``` To install FijiVM+oSCJ:
  1. untar fivm.tar.gz
  2. cd fivm
  3. $ hg clone https://scj-jsr302.googlecode.com/hg/ scj
  4. execute: $ autoreconf -i $ ./configure $ make

To update oSCJ: cd fivm/scj $ hg pull $ hg update

Now, all you need is located in fivm/scj/oSCJ. - there is examples/ dir with all the example applications and also "scj/" dir that contains oSCJ L0 implementation. Just enter e.g. fivm/scj/oSCJ/examples/helloworld and type ./build.sh - you can also observe all the building parameters (really easy!). - for a more complicated case study and build parameters, see fivm/scj/oSCJ/examples/minicdx ```

• Ovm - You can check-out our Ovm distribution from : hg clone https://ovm.scj-jsr302.googlecode.com/hg/ ovm


  See our readme file for more details about installing and running oSCJ with Ovm.
