40 * A class providing APIs for the CORBA Object Request Broker
41 * features. The <code>ORB</code> class also provides
42 * "pluggable ORB implementation" APIs that allow another vendor's ORB
43 * implementation to be used.
44 * <P>
45 * An ORB makes it possible for CORBA objects to communicate
46 * with each other by connecting objects making requests (clients) with
47 * objects servicing requests (servers).
48 * <P>
49 *
50 * The <code>ORB</code> class, which
51 * encapsulates generic CORBA functionality, does the following:
52 * (Note that items 5 and 6, which include most of the methods in
53 * the class <code>ORB</code>, are typically used with the <code>Dynamic Invocation
54 * Interface</code> (DII) and the <code>Dynamic Skeleton Interface</code>
55 * (DSI).
56 * These interfaces may be used by a developer directly, but
57 * most commonly they are used by the ORB internally and are
58 * not seen by the general programmer.)
59 * <OL>
60 * <li> initializes the ORB implementation by supplying values for
61 * predefined properties and environmental parameters
62 * <li> obtains initial object references to services such as
63 * the NameService using the method <code>resolve_initial_references</code>
64 * <li> converts object references to strings and back
65 * <li> connects the ORB to a servant (an instance of a CORBA object
66 * implementation) and disconnects the ORB from a servant
67 * <li> creates objects such as
68 * <ul>
69 * <li><code>TypeCode</code>
70 * <li><code>Any</code>
71 * <li><code>NamedValue</code>
72 * <li><code>Context</code>
73 * <li><code>Environment</code>
74 * <li>lists (such as <code>NVList</code>) containing these objects
75 * </ul>
76 * <li> sends multiple messages in the DII
77 * </OL>
78 *
79 * <P>
80 * The <code>ORB</code> class can be used to obtain references to objects
81 * implemented anywhere on the network.
82 * <P>
83 * An application or applet gains access to the CORBA environment
84 * by initializing itself into an <code>ORB</code> using one of
85 * three <code>init</code> methods. Two of the three methods use the properties
86 * (associations of a name with a value) shown in the
87 * table below.<BR>
88 * <TABLE BORDER=1 SUMMARY="Standard Java CORBA Properties">
89 * <TR><TH>Property Name</TH> <TH>Property Value</TH></TR>
90 * <CAPTION>Standard Java CORBA Properties:</CAPTION>
91 * <TR><TD>org.omg.CORBA.ORBClass</TD>
92 * <TD>class name of an ORB implementation</TD></TR>
93 * <TR><TD>org.omg.CORBA.ORBSingletonClass</TD>
94 * <TD>class name of the ORB returned by <code>init()</code></TD></TR>
95 * </TABLE>
96 * <P>
97 * These properties allow a different vendor's <code>ORB</code>
98 * implementation to be "plugged in."
99 * <P>
100 * When an ORB instance is being created, the class name of the ORB
101 * implementation is located using
102 * the following standard search order:<P>
103 *
104 * <OL>
105 * <LI>check in Applet parameter or application string array, if any
106 *
107 * <LI>check in properties parameter, if any
108 *
109 * <LI>check in the System properties
110 *
111 * <LI>check in the orb.properties file located in the user.home
112 * directory (if any)
113 *
114 * <LI>check in the orb.properties file located in the java.home/lib
115 * directory (if any)
116 *
117 * <LI>fall back on a hardcoded default behavior (use the Java IDL
118 * implementation)
119 * </OL>
120 * <P>
121 * Note that Java IDL provides a default implementation for the
122 * fully-functional ORB and for the Singleton ORB. When the method
123 * <code>init</code> is given no parameters, the default Singleton
124 * ORB is returned. When the method <code>init</code> is given parameters
125 * but no ORB class is specified, the Java IDL ORB implementation
126 * is returned.
127 * <P>
128 * The following code fragment creates an <code>ORB</code> object
129 * initialized with the default ORB Singleton.
130 * This ORB has a
131 * restricted implementation to prevent malicious applets from doing
132 * anything beyond creating typecodes.
133 * It is called a singleton
134 * because there is only one instance for an entire virtual machine.
135 * <PRE>
136 * ORB orb = ORB.init();
137 * </PRE>
138 * <P>
139 * The following code fragment creates an <code>ORB</code> object
140 * for an application. The parameter <code>args</code>
141 * represents the arguments supplied to the application's <code>main</code>
142 * method. Since the property specifies the ORB class to be
143 * "SomeORBImplementation", the new ORB will be initialized with
144 * that ORB implementation. If p had been null,
145 * and the arguments had not specified an ORB class,
146 * the new ORB would have been
147 * initialized with the default Java IDL implementation.
148 * <PRE>
149 * Properties p = new Properties();
150 * p.put("org.omg.CORBA.ORBClass", "SomeORBImplementation");
151 * ORB orb = ORB.init(args, p);
152 * </PRE>
153 * <P>
154 * The following code fragment creates an <code>ORB</code> object
155 * for the applet supplied as the first parameter. If the given
156 * applet does not specify an ORB class, the new ORB will be
157 * initialized with the default Java IDL implementation.
158 * <PRE>
159 * ORB orb = ORB.init(myApplet, null);
160 * </PRE>
161 * <P>
162 * An application or applet can be initialized in one or more ORBs.
163 * ORB initialization is a bootstrap call into the CORBA world.
