JNDI环境变量
| Property Name | Description |
|---|---|
| java.naming.applet | An instance of java.applet.Applet. The applet parameters of this applet instance are used to obtain certain environment properties. See the next section for details. Constant: Context.APPLET  Default: None. |
| java.naming.authoritative | A string ("true" or "false") that specifies the authoritative source of the service requested. If you set this property to "true", then you are asking the service provider to use the most authoritative source for the service (such as a master server). Otherwise the source need not be (but can be) authoritative. Constant: Context.AUTHORITATIVE Default: "false" |
| java.naming.batchsize | The string representation of an integer that specifies the preferred batch size to use when returning data via the service's protocol. See the Searches  lesson for details and an example. Constant: Context.BATCHSIZE Default: Provider's default. Example: "10" |
| java.naming.dns.url | A URL string that specifies the DNS host and domain names to use for the "jndi" URL context implementation. Constant: Context.DNS_URL Default: None. Example: "dns://dnsserver/wiz.com" |
| java.naming.factory.control | Colon-separated list of class names of control factories. Each class must implement the ControlFactory interface. This property is used byControlFactory.getControlInstance() , which in turn is used by service providers. See the Controls and Extensions lesson for details. Constant: LdapContext.CONTROL_FACTORIES Default: The empty list. Example: "com.wiz.jndi.ldap.ControlFactory:vendorX.ldap.VendorXControlFactory" |
| java.naming.factory.initial | Class name of the initial context factory. Class must implement theInitialContextFactory interface. This class is instantiated by the InitialContextconstructor. You must set this property, unless you pass only URL names to theInitialContext methods. Constant: Context.INITIAL_CONTEXT_FACTORY Default: None. Example: "com.sun.jndi.ldap.LdapCtxFactory" |
| java.naming.factory.object | Colon-separated list of class names of object factories. Each class must implement the ObjectFactory or DirObjectFactory interface. This property is used byNamingManager.getObjectInstance() and DirectoryManager.getObjectInstance() , which in turn are used by service providers. See the Java Objects and the Directory  trail for details. Constant: Context.OBJECT_FACTORIES Default: The empty list. Example: "com.wiz.jndi.ldap.AttrsToRemote:com.wiz.jndi.ldap.AttrsToCorba" |
| java.naming.factory.state | Colon-separated list of class names of state factories. Each class must implement the StateFactory or DirStateFactory interface. This property is used byNamingManager.getStateToBind() and DirectoryManager.getStateToBind() , which in turn are used by service providers. See the Java Objects and the Directory trail for details. Constant: Context.STATE_FACTORIES Default: The empty list. Example: "com.wiz.jndi.ldap.RemoteToAttrs:com.wiz.jndi.ldap.CorbaToAttrs" |
| java.naming.factory.url.pkgs | Colon-separated list of package prefixes of URL context factories. The prefix consists of the URL scheme id and a suffix to construct the class name, as follows:
prefix.schemeId.schemeIdURLContextFactoryFor example, suppose the prefix is "vendorZ.jndi" and the URL scheme id is "ldap", the complete class name is vendorZ.jndi.ldap.ldapURLContextFactory. Each class whose name is constructed in this manner must implement the ObjectFactory orDirObjectFactory interface and follow the rules for processing URL names. The package prefix "com.sun.jndi.url" is always appended to the end of the list specified by this property. This property is used when a URL name is passed to theInitialContext methods. See the URL  lesson for more information. Constant: Context.URL_PKG_PREFIXES Default: The empty list. Example: com.wiz.jndi.url:vendorZ.jndi |
| java.naming.language | A string specifying the preferred language to use with this service. The values of this property are defined by RFC 1766. Constant: Context.LANGUAGE Default: Provider's default. Example: "en-US" |
| java.naming.provider.url | A URL string for configuring the service provider specified by the"java.naming.factory.initial" property. Constant: Context.PROVIDER_URL Default: Provider's default. Example: "ldap://localhost:389/o=JNDITutorial" |
| java.naming.referral | A string specifying how the service provider should handle referrals; one of"throw", "ignore", or "follow". See the Referrals lesson for details and examples. Constant: Context.REFERRAL Default: Provider's default. Example: "throw" |
| java.naming.security.authentication | A string specifying the type of authentication to use; one of "none", "simple","strong", or a provider-specific string. See the Security lesson for details and examples. Constant: Context.SECURITY_AUTHENTICATION Default: Provider's default. Example: "simple" |
| java.naming.security.credentials | An object specifying the credentials of the entity performing the authentication. Its type is determined by the service provider. See the Security lesson for details and examples. Constant: Context.SECURITY_CREDENTIALS Default: Provider's default. Example: A char[] containing "secret." |
| java.naming.security.principal | A string that specifies the identity of the entity performing the authentication. See the Security lesson for details and examples. Constant: Context.SECURITY_PRINCIPAL Default: Provider's default. Example: "cn=Directory Manager, o=JNDITutorial" |
| java.naming.security.protocol | A string specifying the security protocol to use. See the Security lesson for details and an example. Constant: Context.SECURITY_PROTOCOL Default: Provider's default. Example: "ssl" |
