Hi ,
when implementing a queue receiver and a topic receiver i find a diffrence . When i use queueReceiver.receive() for a queue i get all the messages which have been put in queue.
But when i do the same thing in a topic subscriber.receive().

Can any one tell me the reason .

hi,
my application needs an abstraction over log4j . so we are using jakarta commons logging . But the problem is that we need diffrent appenders for diffrent modules . Is there any way that we can use appeneders from jcl . or is there any way that we can specify more that one appenders in log4j properties file .
Thanks in advance.

I am looking to use websphere application server feature dynacache in hibernate. Other than implementing org.hibernate.cache.CacheProvider and org.hibernate.cache.Cache, what else do I need to do? Can anybody please help me in this regard? Also, I am bit puzzled on the configuration settings to be done in WAS in this regard.

Is thre any thing that i can do to prevent that . Please suggest me something .
