RE: J2EE (Spring) + Flex + Tomcat 6.0.18 problem
if your bean implemenents implements Lifecycle it is likely that you
LifecycleBean is not running in which case you'll need to restart it e.g
true
if(!context.getBean("lifecycle").isRunning())
context.getBean("lifecycle").start();
if your bean implelements FactoryBean then increase the
timeToLive(default is 120sec) or maxElementsInMemory(default is 1) or
maxElementsOnDisk(default is 1000)
post your code if you need further assistance
