| /** |
| * This interface represents a naming context, which |
| * consists of a set of name-to-object bindings. |
| * It contains methods for examining and updating these bindings. |
| * |
| * <h1>Names</h1> |
| * Each name passed as an argument to a {@code Context} method is relative |
| * to that context. The empty name is used to name the context itself. |
| * A name parameter may never be null. |
| * <p> |
| * Most of the methods have overloaded versions with one taking a |
| * <code>Name</code> parameter and one taking a <code>String</code>. |
| * These overloaded versions are equivalent in that if |
| * the <code>Name</code> and <code>String</code> parameters are just |
| * different representations of the same name, then the overloaded |
| * versions of the same methods behave the same. |
| * In the method descriptions below, only one version is fully documented. |
| * The second version instead has a link to the first: the same |
| * documentation applies to both. |
| * <p> |
| * For systems that support federation, {@code String} name arguments to |
| * {@code Context} methods are composite names. Name arguments that are |
| * instances of {@code CompositeName} are treated as composite names, |
| * while {@code Name} arguments that are not instances of |
| * {@code CompositeName} are treated as compound names (which might be |
| * instances of {@code CompoundName} or other implementations of compound |
| * names). This allows the results of {@code NameParser.parse()} to be used as |
| * arguments to the {@code Context} methods. |
| * Prior to JNDI 1.2, all name arguments were treated as composite names. |
| *<p> |
| * Furthermore, for systems that support federation, all names returned |
| * in a {@code NamingEnumeration} |
| * from {@code list()} and {@code listBindings()} are composite names |
| * represented as strings. |
| * See {@code CompositeName} for the string syntax of names. |
| *<p> |
| * For systems that do not support federation, the name arguments (in |
| * either {@code Name} or {@code String} forms) and the names returned in |
| * {@code NamingEnumeration} may be names in their own namespace rather than |
| * names in a composite namespace, at the discretion of the service |
| * provider. |
| * |
| *<h1>Exceptions</h1> |
| * All the methods in this interface can throw a {@code NamingException} or |
| * any of its subclasses. See {@code NamingException} and their subclasses |
| * for details on each exception. |
| * |
| *<h1>Concurrent Access</h1> |
| * A Context instance is not guaranteed to be synchronized against |
| * concurrent access by multiple threads. Threads that need to access |
| * a single Context instance concurrently should synchronize amongst |
| * themselves and provide the necessary locking. Multiple threads |
| * each manipulating a different Context instance need not |
| * synchronize. Note that the {@link #lookup(Name) lookup} |
| * method, when passed an empty name, will return a new Context instance |
| * representing the same naming context. |
| *<p> |
| * For purposes of concurrency control, |
| * a Context operation that returns a {@code NamingEnumeration} is |
| * not considered to have completed while the enumeration is still in |
| * use, or while any referrals generated by that operation are still |
| * being followed. |
| * |
| * |
| *<h1>Parameters</h1> |
| * A {@code Name} parameter passed to any method of the |
| * {@code Context} interface or one of its subinterfaces |
| * will not be modified by the service provider. |
| * The service provider may keep a reference to it |
| * for the duration of the operation, including any enumeration of the |
| * method's results and the processing of any referrals generated. |
| * The caller should not modify the object during this time. |
| * A {@code Name} returned by any such method is owned by the caller. |
| * The caller may subsequently modify it; the service provider may not. |
| * |
| * |
| *<h1>Environment Properties</h1> |
| *<p> |
| * JNDI applications need a way to communicate various preferences |
| * and properties that define the environment in which naming and |
| * directory services are accessed. For example, a context might |
| * require specification of security credentials in order to access |
| * the service. Another context might require that server configuration |
| * information be supplied. These are referred to as the <em>environment</em> |
| * of a context. The {@code Context} interface provides methods for |
| * retrieving and updating this environment. |
| *<p> |
| * The environment is inherited from the parent context as |
| * context methods proceed from one context to the next. Changes to |
| * the environment of one context do not directly affect those |
| * of other contexts. |
| *<p> |
| * It is implementation-dependent when environment properties are used |
| * and/or verified for validity. For example, some of the |
| * security-related properties are used by service providers to "log in" |
| * to the directory. This login process might occur at the time the |
| * context is created, or the first time a method is invoked on the |
| * context. When, and whether this occurs at all, is |
| * implementation-dependent. When environment properties are added or |
| * removed from the context, verifying the validity of the changes is again |
| * implementation-dependent. For example, verification of some properties |
| * might occur at the time the change is made, or at the time the next |
| * operation is performed on the context, or not at all. |
| *<p> |
| * Any object with a reference to a context may examine that context's |
| * environment. Sensitive information such as clear-text |
| * passwords should not be stored there unless the implementation is |
| * known to protect it. |
| * |
| *<p> |
| *<a name=RESOURCEFILES></a> |
| *<h1>Resource Files</h1> |
| *<p> |
| * To simplify the task of setting up the environment |
| * required by a JNDI application, |
| * application components and service providers may be distributed |
| * along with <em>resource files.</em> |
| * A JNDI resource file is a file in the properties file format (see |
| * {@link java.util.Properties#load java.util.Properties}), |
| * containing a list of key/value pairs. |
| * The key is the name of the property (e.g. "java.naming.factory.object") |
| * and the value is a string in the format defined |
| * for that property. Here is an example of a JNDI resource file: |
| * |
| * <blockquote>{@code |
| * java.naming.factory.object=com.sun.jndi.ldap.AttrsToCorba:com.wiz.from.Person |
| * java.naming.factory.state=com.sun.jndi.ldap.CorbaToAttrs:com.wiz.from.Person |
| * java.naming.factory.control=com.sun.jndi.ldap.ResponseControlFactory |
| * }</blockquote> |
| * |
| * The JNDI class library reads the resource files and makes the property |
| * values freely available. Thus JNDI resource files should be considered |
| * to be "world readable", and sensitive information such as clear-text |
| * passwords should not be stored there. |
| *<p> |
| * There are two kinds of JNDI resource files: |
| * <em>provider</em> and <em>application</em>. |
| * |
| * <h2>Provider Resource Files</h2> |
| * |
| * Each service provider has an optional resource that lists properties |
| * specific to that provider. The name of this resource is: |
| * <blockquote> |
| * [<em>prefix</em>/]{@code jndiprovider.properties} |
| * </blockquote> |
| * where <em>prefix</em> is |
| * the package name of the provider's context implementation(s), |
| * with each period (".") converted to a slash ("/"). |
| * |
| * For example, suppose a service provider defines a context |
| * implementation with class name {@code com.sun.jndi.ldap.LdapCtx}. |
| * The provider resource for this provider is named |
| * {@code com/sun/jndi/ldap/jndiprovider.properties}. If the class is |
| * not in a package, the resource's name is simply |
| * {@code jndiprovider.properties}. |
| * |
| * <p> |
| * <a name=LISTPROPS></a> |
| * Certain methods in the JNDI class library make use of the standard |
| * JNDI properties that specify lists of JNDI factories: |
| * <ul> |
| * <li>java.naming.factory.object |
| * <li>java.naming.factory.state |
| * <li>java.naming.factory.control |
| * <li>java.naming.factory.url.pkgs |
| * </ul> |
| * The JNDI library will consult the provider resource file |
| * when determining the values of these properties. |
| * Properties other than these may be set in the provider |
| * resource file at the discretion of the service provider. |
| * The service provider's documentation should clearly state which |
| * properties are allowed; other properties in the file will be ignored. |
| * |
| * <h2>Application Resource Files</h2> |
| * |
| * When an application is deployed, it will generally have several |
| * codebase directories and JARs in its classpath. JNDI locates (using |
| * {@link ClassLoader#getResources ClassLoader.getResources()}) |
| * all <em>application resource files</em> named {@code jndi.properties} |
| * in the classpath. |
| * In addition, if the Java installation directory contains a built-in |
| * properties file, typically {@code conf/jndi.properties}, |
| * JNDI treats it as an additional application resource file. |
| * All of the properties contained in these files are placed |
| * into the environment of the initial context. This environment |
| * is then inherited by other contexts. |
| * |
| * <p> |
| * For each property found in more than one application resource file, |
| * JNDI uses the first value found or, in a few cases where it makes |
| * sense to do so, it concatenates all of the values (details are given |
| * below). |
| * For example, if the "java.naming.factory.object" property is found in |
| * three {@code jndi.properties} resource files, the |
| * list of object factories is a concatenation of the property |
| * values from all three files. |
| * Using this scheme, each deployable component is responsible for |
| * listing the factories that it exports. JNDI automatically |
| * collects and uses all of these export lists when searching for factory |
| * classes. |
| * |
| * <h2>Search Algorithm for Properties</h2> |
| * |
| * When JNDI constructs an initial context, the context's environment |
| * is initialized with properties defined in the environment parameter |
| * passed to the constructor, the system properties, |
| * and the application resource files. See |
| * <a href=InitialContext.html#ENVIRONMENT>{@code InitialContext}</a> |
| * for details. |
| * This initial environment is then inherited by other context instances. |
| * |
| * <p> |
| * When the JNDI class library needs to determine |
| * the value of a property, it does so by merging |
| * the values from the following two sources, in order: |
| * <ol> |
| * <li>The environment of the context being operated on. |
| * <li>The provider resource file ({@code jndiprovider.properties}) |
| * for the context being operated on. |
| * </ol> |
| * For each property found in both of these two sources, |
| * JNDI determines the property's value as follows. If the property is |
| * one of the standard JNDI properties that specify a list of JNDI |
| * factories (listed <a href=#LISTPROPS>above</a>), the values are |
| * concatenated into a single colon-separated list. For other |
| * properties, only the first value found is used. |
| * |
| * <p> |
| * When a service provider needs to determine the value of a property, |
| * it will generally take that value directly from the environment. |
| * A service provider may define provider-specific properties |
| * to be placed in its own provider resource file. In that |
| * case it should merge values as described in the previous paragraph. |
| * |
| * <p> |
| * In this way, each service provider developer can specify a list of |
| * factories to use with that service provider. These can be modified by |
| * the application resources specified by the deployer of the application, |
| * which in turn can be modified by the user. |
