Class JNDIProvided<T>

java.lang.Object

org.picocontainer.gems.jndi.JNDIProvided<T>

All Implemented Interfaces:

Serializable, ComponentAdapter<T>

public class JNDIProvided<T>
extends Object
implements ComponentAdapter<T>, Serializable

Represents dependency provided via JNDI. This dependency is not to be managed by container at all, so there is no lifecycle, no monitoring etc.

JNDIProvided

public JNDIProvided(Object componentKey,
            JNDIObjectReference<T> reference,
            Class<T> type)

Create adapter with specified key and reference

Parameters:

componentKey - component key

reference - JNDI reference storing component

type - the type that the JNDIObjectReference will return.

JNDIProvided

public JNDIProvided(JNDIObjectReference<T> reference,
            Class<T> type)

Create adapter with JNDI reference. referenced object class will be takes as key

Parameters:

reference - JNDI reference storing component

type - the type that the JNDIObjectReference will return.

JNDIProvided

public JNDIProvided(String jndiName,
            Class<T> type)
             throws NamingException

Create adapter based on JNDI name. I leave this unchecked because type is really not known at this time

Parameters:

jndiName - name to be used

type - the type that the JNDIObjectReference will return.

Throws:

NamingException - will be thrown if something goes wrong in JNDI
