public static final String CPE
The environment property into which getContinuationContext() stores the value of the CannotProceedException parameter. The value of this field is java.naming.spi.CannotProceedException.
- Field Value:
- "java.naming.spi.CannotProceedException"
public static Context getContinuationContext(CannotProceedException cpe) throws NamingException
Creates a context in which the context operation must be continued. This method is used by operations on names that span multiple namespaces.
- Parameters:
cpe
- the exception that triggered this continuation. This method obtains the environment (CannotProceedException.getEnvironment()
and sets the environment propertyCPE
= cpe.
- Returns:
- a non null context for continuing the operation
- Throws:
NamingException
- if the naming problems have occured
public static Context getInitialContext(Hashtable environment) throws NamingException
Creates the initial context. If the initial object factory builder has been set withsetObjectFactoryBuilder(ObjectFactoryBuilder)
, the work is delegated to this builder. Otherwise, the method searches for the property Context.INITIAL_CONTEXT_FACTORY first in the passed table and then in the system properties. The value of this property is uses as a class name to install the context factory. The corresponding class must exist, be public and have the public parameterless constructor.
- Parameters:
environment
- the properties, used to create the context.
- Returns:
- the created context
- Throws:
NamingException
- if throws by the context factory
public static Object getObjectInstance(Object refInfo, Name name, Context nameCtx, Hashtable environment) throws Exception
Creates an object for the specified name context, environment and referencing context object.If the builder factory is set by
setObjectFactoryBuilder(ObjectFactoryBuilder)
, the call is delegated to that factory. Otherwise, the object is created using the following rules:
- If the referencing object (refInfo) contains the factory class name, the object is created by this factory. If the creation fails, the parameter refInfo is returned as the method return value.
- If the referencing object has no factory class name, and the addresses are StringRefAddrs having the address type "URL", the object is created by the URL context factory. The used factory corresponds the the naming schema of the each URL. If the attempt to create the object this way is not successful, the subsequent rule is tried.
- If the refInfo is not an instance of Reference or Referencable (for example, null), the object is created by the factories, specified in the Context.OBJECT_FACTORIES property of the environment and the provider resource file, associated with the nameCtx. The value of this property is the colon separated list of the possible factories. If none of the factories can be loaded, the refInfo is returned.
The object factory must be public and have the public parameterless constructor.
- Parameters:
refInfo
- the referencing object, for which the new object must be created (can be null). If not null, it is usually an instance of theReference
orReferenceable
.name
- the name of the object. The name is relative to the nameCtx naming context. The value of this parameter can be null if the name is not specified.nameCtx
- the naming context, in which scope the name of the new object is specified. If this parameter is null, the name is specified in the scope of the initial context.environment
- contains additional information for creating the object. This paramter can be null if there is no need to provide any additional information.
- Returns:
- the created object. If the creation fails, in some cases the parameter refInfo may be returned.
- Throws:
Exception
- if the object factory throws it. The object factory only throws an exception if it does not want other factories to be used to create the object.
public static Object getStateToBind(Object obj, Name name, Context nameCtx, Hashtable environment) throws NamingException
Get the object state for binding.
- Parameters:
obj
- the object, for that the binding state must be retrieved. Cannot be null.name
- the name of this object, related to the nameCtx. Can be null if not specified.nameCtx
- the naming context, to that the object name is related. Can be null if the name is related to the initial default context.environment
- the properties for creating the object state. Can be null if no properties are provided.
- Returns:
- the object state for binding, may be null if no changes are returned by the factory
- Throws:
NamingException
-
public static Context getURLContext(String scheme, Hashtable environment) throws NamingException
Creates the URL context for the given URL scheme id.The class name of the factory that creates the context has the naming pattern scheme-idURLContextFactory. For instance, the factory for the "ftp" scheme should be named "ftpURLContextFactory". The Context.URL_PKG_PREFIXES environment property contains the colon-separated list of the possible package prefixes. The package name is constructed by concatenating the package prefix with the scheme id.
If the factory class cannot be found in the specified packages, the system will try to use the default internal factory for the given scheme.
After the factory is instantiated, its method
ObjectFactory.getObjectInstance(Object, Name, Context, Hashtable)
is called to create and return the object instance.
- Parameters:
scheme
- the url scheme that must be supported by the given contextenvironment
- the properties for creating the factory and context (may be null)
- Returns:
- the created context
- Throws:
NamingException
- if thrown by the factory when creating the context.
public static boolean hasInitialContextFactoryBuilder()
Checks if the initial context factory builder has been set.
- Returns:
- true if the builder has been set
public static void setInitialContextFactoryBuilder(InitialContextFactoryBuilder builder) throws NamingException
Sets the initial context factory builder.
- Parameters:
builder
- the builder to set
- Throws:
SecurityException
- if the builder cannot be installed due security restrictions.NamingException
- if the builder cannot be installed due other reasonsIllegalStateException
- if setting the builder repeatedly
- See Also:
hasInitialContextFactoryBuilder()
public static void setObjectFactoryBuilder(ObjectFactoryBuilder builder) throws NamingException
Sets the initial object factory builder.
- Parameters:
builder
- the builder to set
- Throws:
SecurityException
- if the builder cannot be installed due security restrictions.NamingException
- if the builder cannot be installed due other reasonsIllegalStateException
- if setting the builder repeatedly
