Class JndiLocator

java.lang.Object
  extended by org.apache.shiro.jndi.JndiLocator
Direct Known Subclasses:
JndiObjectFactory, JndiRealmFactory

public class JndiLocator
extends Object

Convenient superclass for JNDI accessors, providing "jndiTemplate" and "jndiEnvironment" bean properties.

Note that this implementation is an almost exact combined copy of the Spring Framework's 'JndiAccessor' and 'JndiLocatorSupport' classes from their 2.5.4 distribution - we didn't want to re-invent the wheel, but not require a full dependency on the Spring framework, nor does Spring make available only its JNDI classes in a small jar, or we would have used that. Since Shiro is also Apache 2.0 licensed, all regular licenses and conditions and authors have remained in tact.

Since:
1.1

Method Detail

setJndiTemplate

public void setJndiTemplate(JndiTemplate jndiTemplate)
Set the JNDI template to use for JNDI lookups.

You can also specify JNDI environment settings via "jndiEnvironment".

See Also:
setJndiEnvironment(java.util.Properties)

getJndiTemplate

public JndiTemplate getJndiTemplate()
Return the JNDI template to use for JNDI lookups.


setJndiEnvironment

public void setJndiEnvironment(Properties jndiEnvironment)
Set the JNDI environment to use for JNDI lookups.

Creates a JndiTemplate with the given environment settings.

See Also:
setJndiTemplate(org.apache.shiro.jndi.JndiTemplate)

getJndiEnvironment

public Properties getJndiEnvironment()
Return the JNDI environment to use for JNDI lookups.


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 (e.g. "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
Returns:
the obtained object
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
requiredType - the required type of the object
Returns:
the obtained object
Throws:
NamingException - if the JNDI lookup failed
See Also:
setResourceRef(boolean)

convertJndiName

protected String convertJndiName(String jndiName)
Convert the given JNDI name into the actual JNDI name to use.

The default implementation applies the "java:comp/env/" prefix if "resourceRef" is "true" and no other scheme (e.g. "java:") is given.

Parameters:
jndiName - the original JNDI name
Returns:
the JNDI name to use

CONTAINER_PREFIX, setResourceRef(boolean)
