But I have a question: When the connectionFactory brokerUrl is changed to ssl://192.168.0.2:443, where 192.168.0.2 could be any valid address other than localhost, and the environment variable ACTIVEMQ_OPTS is set to -Xmx512M -Dorg.apache.activemq.UseDedicatedTaskRunner=true -Dderby.storage.fileSyncTransactionLog=true -Dcom.sun.management.jmxremote -Djavax.net.ssl.keyStore=C:\work\ActiveMQ401\broker.ks -Djavax.net.ssl.keyStorePassword=secret -Djavax.net.ssl.trustStore=c:\work\ActiveMQ401\broker.ts -Djavax.net.ssl.trustStorePassword=secret performance slows down to approximately 1/2 min. per message/response compared to less than 1 sec. when set to tcp://192.168.0.2:61616. Does it mean this is unusable in production environments? Thanks, Rolando Great stuff!

But I have a question:

When the connectionFactory brokerUrl is changed to ssl://192.168.0.2:443, where 192.168.0.2 could be any valid address other than localhost, and the environment variable ACTIVEMQ_OPTS is set to

-Xmx512M -Dorg.apache.activemq.UseDedicatedTaskRunner=true -Dderby.storage.fileSyncTransactionLog=true -Dcom.sun.management.jmxremote -Djavax.net.ssl.keyStore=C:\work\ActiveMQ401\broker.ks -Djavax.net.ssl.keyStorePassword=secret -Djavax.net.ssl.trustStore=c:\work\ActiveMQ401\broker.ts -Djavax.net.ssl.trustStorePassword=secret

performance slows down to approximately 1/2 min. per message/response compared to less than 1 sec. when set to tcp://192.168.0.2:61616.

Does it mean this is unusable in production environments?

So I've been porting the sample using the new JMS namespace. So, while the original sample is working fine, when I change the content of server-context.xml like here: I get the following exception Caused by: java.lang.NoSuchMethodException: blog.jms.remoting.RegistrationServiceImpl.processRequest(org.springframework.remoting.support.RemoteInvocation) I think I've to write a custom message converter but I do not understand why Thanks Andrea Hi I'm testing spring 2.5.

When testing the performance of this request/reply solution, it turns out that only about 14 requests per second gets processed at full speed on a "yesteryear"-machine. (Just using a loop that sends the next request when the reply arrives) Is this somehow due to lack of pooling? Or is it maybe that the proxy creates a new temporary reply queue for each request?

Indrit,

Could you elaborate on this requirement a bit? My initial reaction is that it would require some customization - if you are talking about a splitter/aggregator model. For that scenario, QueueRequestor is too fine-grained - each request/reply unit-of-work is operating on a single message.
