public abstract class JndiLocatorSupport
extends JndiAccessor

Convenient superclass for classes that can locate any number of JNDI objects. Derives from JndiAccessor to inherit the "jndiTemplate" and "jndiEnvironment" bean properties.

JNDI names may or may not include the "java:comp/env/" prefix expected by J2EE applications when accessing a locally mapped (ENC - Environmental Naming Context) resource. If it doesn't, the "java:comp/env/" prefix will be prepended if the "resourceRef" property is true (the default is false) and no other scheme (e.g. "java:") is given.

Method Detail

setResourceRef

public void setResourceRef(boolean resourceRef)

Set whether the lookup occurs in a J2EE container, i.e. if the prefix "java:comp/env/" needs to be added if the JNDI name doesn't already contain it. Default is "false".

Note: Will only get applied if no other scheme like "java:" is given.

isResourceRef

public boolean isResourceRef()

Return whether the lookup occurs in a J2EE container.

lookup

protected Object lookup(String jndiName)
                 throws NamingException

Perform an actual JNDI lookup for the given name via the JndiTemplate. If the name doesn't begin with "java:comp/env/", this prefix is added if resourceRef is set to true.

Parameters:

jndiName - the JNDI name to look up

Throws:

NamingException - if the JNDI lookup failed

See Also:

setResourceRef(boolean)

lookup

protected Object lookup(String jndiName,
                        Class requiredType)
                 throws NamingException

Perform an actual JNDI lookup for the given name via the JndiTemplate. If the name doesn't begin with "java:comp/env/", this prefix is added if resourceRef is set to true.

Parameters:

jndiName - the JNDI name to look up

Throws:

NamingException - if the JNDI lookup failed

See Also:

setResourceRef(boolean)

convertJndiName

protected String convertJndiName(String jndiName)

Convert the given JNDI name to the actual JNDI name to use. Default implementation applies the "java:comp/env/" prefix if resourceRef is true and no other scheme like "java:" is given.

Parameters:

jndiName - the original JNDI name

Returns:

the JNDI name to use
