public abstract class NamingEntry
extends Object

NamingEntry Base class for all jndi related entities. Instances of subclasses of this class are declared in jetty.xml or in a webapp's WEB-INF/jetty-env.xml file. NOTE: that all NamingEntries will be bound in a single namespace. The "global" level is just in the top level context. The "local" level is a context specific to a webapp.

Constructor Detail

NamingEntry

protected NamingEntry(Object scope,
           String jndiName)
               throws NamingException

Throws:

NamingException

NamingEntry

protected NamingEntry(String jndiName)
               throws NamingException

Create a NamingEntry. A NamingEntry is a name associated with a value which can later be looked up in JNDI by a webapp. We create the NamingEntry and put it into JNDI where it can be linked to the webapp's env-entry, resource-ref etc entries.

Parameters:

jndiName - the name of the object which will eventually be in java:comp/env

Throws:

NamingException

Method Detail

toString

public String toString()

Overrides:

toString in class Object

bindToENC

public void bindToENC(String localName)
               throws NamingException

Add a java:comp/env binding for the object represented by this NamingEntry, but bind it as the name supplied

Throws:

NamingException

unbindENC

public void unbindENC()

Unbind this NamingEntry from a java:comp/env

release

public void release()

Unbind this NamingEntry entirely

getJndiName

public String getJndiName()

Get the unique name of the object relative to the scope

Returns:

the unique jndi name of the object

getJndiNameInScope

public String getJndiNameInScope()

Get the name of the object, fully qualified with the scope

Returns:

the name of the object, fully qualified with the scope

save

protected void save(Object object)
             throws NamingException

Save the NamingEntry for later use. Saving is done by binding the NamingEntry itself, and the value it represents into JNDI. In this way, we can link to the value it represents later, but also still retrieve the NamingEntry itself too. The object is bound at the jndiName passed in. This NamingEntry is bound at __/jndiName. eg jdbc/foo : DataSource __/jdbc/foo : NamingEntry

Throws:

NamingException
