33  ** <p>The <tt>RuntimeMain</tt> class allows to boot a CORBA object (implemented using the
34  ** system component framework) using the <tt>Runtime.loadServant</tt> operation. The parameters
35  ** are extracted from the command line information.</p>
36  **
37  ** <p>In its current state, the following information must/may be provided:</p>
38  ** <li>
39  ** <ul>Servant JAR location (mandatory) through the Java <tt>archive.location</tt> system property or
40  ** through the "-ArchiveLocation location" option on the command line.</ul>
41  ** <ul>Servant entrypoint (mandatory) through the Java <tt>archive.entrypoint</tt> system property or
42  ** through the "-ArchiveEntrypoint entrypt" option on the command line.</ul>
43  ** <ul>Initial references (optional) through "-ORBInitRef regname=ior" option on the command line.</ul>
44  ** <ul>System services (optional) through "-SystemService serviceid=entrypoint" option on the command line.</ul>
45  ** <ul>Runtime identity (mandatory) through the Java <tt>runtime.id</tt> system property or
46  ** through the "-RuntimeId rid" option on the command line.</ul>
