| 32 | /** |
| 33 | * This class is the starting context for performing naming operations. |
| 34 | *<p> |
| 35 | * All naming operations are relative to a context. |
| 36 | * The initial context implements the Context interface and |
| 37 | * provides the starting point for resolution of names. |
| 38 | *<p> |
| 39 | * <a name=ENVIRONMENT></a> |
| 40 | * When the initial context is constructed, its environment |
| 41 | * is initialized with properties defined in the environment parameter |
| 42 | * passed to the constructor, and in any |
| 43 | * <a href=Context.html#RESOURCEFILES>application resource files</a>. |
| 44 | * In addition, a small number of standard JNDI properties may |
| 45 | * be specified as system properties or as applet parameters |
| 46 | * (through the use of {@link Context#APPLET}). |
| 47 | * These special properties are listed in the field detail sections of the |
| 48 | * <a href=Context.html#field_detail><tt>Context</tt></a> and |
| 49 | * <a href=ldap/LdapContext.html#field_detail><tt>LdapContext</tt></a> |
| 50 | * interface documentation. |
| 51 | *<p> |
| 52 | * JNDI determines each property's value by merging |
| 53 | * the values from the following two sources, in order: |
| 54 | * <ol> |
| 55 | * <li> |
| 56 | * The first occurrence of the property from the constructor's |
| 57 | * environment parameter and (for appropriate properties) the applet |
| 58 | * parameters and system properties. |
| 59 | * <li> |
| 60 | * The application resource files (<tt>jndi.properties</tt>). |
| 61 | * </ol> |
| 62 | * For each property found in both of these two sources, or in |
| 63 | * more than one application resource file, the property's value |
| 64 | * is determined as follows. If the property is |
| 65 | * one of the standard JNDI properties that specify a list of JNDI |
| 66 | * factories (see <a href=Context.html#LISTPROPS><tt>Context</tt></a>), |
| 67 | * all of the values are |
| 68 | * concatenated into a single colon-separated list. For other |
| 69 | * properties, only the first value found is used. |
| 70 | * |
| 71 | *<p> |
| 72 | * The initial context implementation is determined at runtime. |
| 73 | * The default policy uses the environment property |
| 74 | * "{@link Context#INITIAL_CONTEXT_FACTORY java.naming.factory.initial}", |
| 75 | * which contains the class name of the initial context factory. |
| 76 | * An exception to this policy is made when resolving URL strings, as described |
| 77 | * below. |
| 78 | *<p> |
| 79 | * When a URL string (a <tt>String</tt> of the form |
| 80 | * <em>scheme_id:rest_of_name</em>) is passed as a name parameter to |
| 81 | * any method, a URL context factory for handling that scheme is |
| 82 | * located and used to resolve the URL. If no such factory is found, |
| 83 | * the initial context specified by |
| 84 | * <tt>"java.naming.factory.initial"</tt> is used. Similarly, when a |
| 85 | * <tt>CompositeName</tt> object whose first component is a URL string is |
| 86 | * passed as a name parameter to any method, a URL context factory is |
| 87 | * located and used to resolve the first name component. |
| 88 | * See {@link NamingManager#getURLContext |
| 89 | * <tt>NamingManager.getURLContext()</tt>} for a description of how URL |
| 90 | * context factories are located. |
| 91 | *<p> |
| 92 | * This default policy of locating the initial context and URL context |
| 93 | * factories may be overridden |
| 94 | * by calling |
| 95 | * <tt>NamingManager.setInitialContextFactoryBuilder()</tt>. |
| 96 | *<p> |
| 97 | * NoInitialContextException is thrown when an initial context cannot |
| 98 | * be instantiated. This exception can be thrown during any interaction |
| 99 | * with the InitialContext, not only when the InitialContext is constructed. |
| 100 | * For example, the implementation of the initial context might lazily |
| 101 | * retrieve the context only when actual methods are invoked on it. |
| 102 | * The application should not have any dependency on when the existence |
| 103 | * of an initial context is determined. |
| 104 | *<p> |
| 105 | * When the environment property "java.naming.factory.initial" is |
| 106 | * non-null, the InitialContext constructor will attempt to create the |
| 107 | * initial context specified therein. At that time, the initial context factory |
| 108 | * involved might throw an exception if a problem is encountered. However, |
| 109 | * it is provider implementation-dependent when it verifies and indicates |
| 110 | * to the users of the initial context any environment property- or |
| 111 | * connection- related problems. It can do so lazily--delaying until |
| 112 | * an operation is performed on the context, or eagerly, at the time |
| 113 | * the context is constructed. |
| 114 | *<p> |
| 115 | * An InitialContext instance is not synchronized against concurrent |
| 116 | * access by multiple threads. Multiple threads each manipulating a |
| 117 | * different InitialContext instance need not synchronize. |
| 118 | * Threads that need to access a single InitialContext instance |
| 119 | * concurrently should synchronize amongst themselves and provide the |
| 120 | * necessary locking. |
