The first thing you will need to do for the Add-on kit is build the JAR for it. This involves generating code, so you must have an ASN1C SDK license in place. To run the build, use the provided Ant build script. Run ant build. The build will generate code using asn1c, compile the code, and produce the objsys_nas.jar JAR file.

For the standalone kits, the objsys_nas.jar JAR file is already provided. It contains the class files for the generated NAS code, as well as those run-time class files that the NAS code depends on.

For the standalone unlimited source kit, the objsys_nas.jar JAR file can be re-built if necessary. To run the build, use the provided Ant build script as described above for add-on kits. The build will compile code and reproduce the objsys_nas.jar JAR file.

The easiest way to get started using the add-on is to examine the test_* subdirectories within the package. These contain test programs for encoding and decoding all of the different message types defined in the standards. Typically, code from within these samples can be used to form larger programs that can encode or decode larger message sets.
