You should save the above jars to a dedicated folder (for example, <Magic xpi installation>/JDE_lib), and reference them one by one in either the machine's CLASSPATH or in the Magic.ini file's CLASSPATH.
In the following example, the JDE JCA classes were placed underneath the Magic xpi installation in the JDE_lib folder. This example connects to JDE with an Oracle database. This is why the Oracle JDBC driver's ojdbc5.jar is loaded.
