TargetSource which performs a fresh JNDI lookup for each call.

Can be used as alternative to JndiObjectFactoryBean, to allow for relocating a JNDI object lazily or for each operation (see "lookupOnStartup" and "cache" properties). This is particularly useful during development, as it allows for hot restarting of the JNDI server (for example, a remote JMS server).

Example:

 <bean id="queueConnectionFactoryTarget" class="org.springframework.jndi.JndiObjectTargetSource">
   <property name="jndiName"><value>JmsQueueConnectionFactory</value></property>
   <property name="lookupOnStartup"><value>false</value></property>
 </bean>

 <bean id="queueConnectionFactory" class="org.springframework.aop.framework.ProxyFactoryBean">
   <property name="proxyInterfaces"><value>javax.jms.QueueConnectionFactory</value></property>
   <property name="targetSource"><ref bean="queueConnectionFactoryTarget"/></property>
 </bean>

A createQueueConnection call on the "queueConnectionFactory" proxy will cause a lazy JNDI lookup for "JmsQueueConnectionFactory" and a subsequent delegating call to the retrieved QueueConnectionFactory's createQueueConnection.

Alternatively, use a JndiObjectFactoryBean with a "proxyInterface". "lookupOnStartup" and "cache" can then be specified on the JndiObjectFactoryBean, creating a JndiObjectTargetSource underneath (instead of defining separate ProxyFactoryBean and JndiObjectTargetSource beans).
