If you want to use the CIMCheck command line validation tool or the CIMCheck API you need the following archive:
http://files.cimtool.org/cimcheck-100605.zip
Note that this version has not been synchronised with the latest CIMTool version yet. It corresponds to CIMTool release 1.8.2.
Unzip the archive to create a directory containing the CIMCheck jar files. CIMCheck can then be executed by:
java -jar CIMCheck/CIMCheck.jar [option...] profile_file model_file...
To use the CIMCheck API the jars should be added to the classpath.
