```
public static final String IGNORE_JNDI_PROPERTY_NAME
```
    System property that instructs Spring to ignore a default JNDI environment, i.e. to always return false from isDefaultJndiEnvironmentAvailable().
    The default is "false", allowing for regular default JNDI access e.g. in JndiPropertySource. Switching this flag to true is an optimization for scenarios where nothing is ever to be found for such JNDI fallback searches to begin with, avoiding the repeated JNDI lookup overhead.
    Note that this flag just affects JNDI fallback searches, not explicitly configured JNDI lookups such as for a DataSource or some other environment resource. The flag literally just affects code which attempts JNDI searches based on the JndiLocatorDelegate.isDefaultJndiEnvironmentAvailable() check: in particular, StandardServletEnvironment and StandardPortletEnvironment.

public Object lookup(String jndiName)
              throws NamingException
```
    Description copied from class: JndiLocatorSupport
    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".
    Overrides:
    lookup in class JndiLocatorSupport
    Parameters:
    jndiName - the JNDI name to look up
    Returns:
    the obtained object
    Throws:
    NamingException - if the JNDI lookup failed
