The ECCN classification of ActiveMQ is given as 5D002, see http://www.apache.org/licenses/exports/ I believe this is a self-classification. To answer your question, this bit is relevant (my bolding): "Products classified as ECCN 5D002 , are exported by the ASF under the TSU exception in EAR 740.

Encryption algorithms in ActiveMQ?

2012-05-30 Thread Don Asper
Hi: Does ActiveMQ contain encryption algorithms that preclude it from being shipped to other countries? I see on the ActiveMQ website that password encryption can be done using encrypt and decrypt options of the activemq command, for example. Is other encryption or decryption done by ActiveMQ or is

Without looking at your specific exception, you say everything was working until you changed 2 things. Can you come back here when you have isolated whether the behaviour changes when you go from tcp to nio or when you make the change for kahaDB? If it's for kahaDB, you need to tell us the range

One way is using the feature of multicast broker discovery http://activemq.apache.org/discovery-transport-reference.html Then, every >500ms, a broadcast datagram is sent for each transport on each broker. 239.255.2.3 UDP D=6155 S=6155 The message indicates the transport that is running.

Hi Torsten, thanks. Yes, I've made experiments with 5.5.1 on the server side but had trouble getting it up reliably in my OSGi environment so I'm hesitant to upgrade on the server side. However, the problem resides mainly in the client AFAICS, and that one uses 5.5.1 already. I guess I'll take a p

No ideas? As a work-around I'm now thinking about running a scheduled task that restarts the MessageListener every hour. That's a work-around that shouldn't really be necessary, right? A colleague told me yesterday that he did exactly that in a personal project of his. So, I'm probably not the only
