Compiling the Source Code

Once you have the Java VM version 1.4 or higher installed, simply download and unpack the archive ../coba2.zip. You will find inside the unpacked archive several scripts readily available for compilation and execution purposes. You may re-configure the paths in the scripts for your local machine.

To recompile COBA 2.0, you can use the included Makefile with two targets:

• make app : to compile the command-line version and build the JAR archive applet/cobaapp.jar to store the compiled command-line version.
• make applet : to compile the applet and build the JAR archive applet/cobaUI.jar to store the compiled applet version.

To run COBA 2.0, you can either start the command-line version with: run_app KB_File(or none) Revision_File(or none) Contraction_File(or none)

or start the applet version with: run_applet

run_app is a script that starts the executable cobaapp.jar - the compiled command-line version of COBA 2.0. Please ensure that the path to java and the path to cobaapp.jar are set correctly for your machine.

run_applet is a script that calls the appletviewer to start the JAR archive cobaUI.jar - the compiled applet version of COBA 2.0 - with the security policy policy/revision.policy. Please ensure that the path to appletviewer and the path to cobaUI.jar are set correctly for your machine.
