2013-10-08 Thread Graham Leggett
Hi all, I am having a further problem that has me stumped. I have 8 nodes, each node makes a short lived connection to poll a central activemq server in the expectation of picking up exactly one message for processing, processing may take many seconds to minutes. The activemq server has a queu

Tuning activemq for reliability, not performance

2013-10-08 Thread Graham Leggett
Hi all, We have a system that does heavy message processing where we have very few (tens, hundreds) of messages that take minutes to process each. What we also have is periodic activemq v5.8.0 instability that causes the "java service wrapper" to proactively send a "kill -9" signal to the activ

Hi all, Earlier this afternoon we starting seeing the following exception recorded in our activemq v5.8.0 wrapper.log file. Can anyone shed some light on what it means? INFO | jvm 3| 2013/10/07 15:13:24 | java.lang.NumberFormatException: property JMS_AMQP_MESSAGE_FORMAT was null INFO |

XMPP: does it work for anybody?

2008-06-07 Thread Graham Leggett
Hi all, I have spent over a day trying to get a jabber client (any jabber client) to successfully connect to activemq's XMPP connector, either with or without SSL, and so far I have got nowhere. I know that activemq is listening on an XMPP port, because when I telnet there, I get an XMPP hea

Hi all, A quick Google search to find a straightforward explanation on how to authenticate activemq against an LDAP server uncovered the following message: http://osdir.com/ml/java.activemq.user/2006-05/msg00556.html Following the message resulted in no luck, the server refused to start, wi

ActiveMQ over XMPP over SSL

2008-06-06 Thread Graham Leggett
Hi all, According to http://activemq.apache.org/xmpp.html, it is possible to run ActiveMQ over XMPP. According to http://activemq.apache.org/how-do-i-use-ssl.html, it is possible to run ActiveMQ over SSL. What doesn't seem clear, is whether ActiveMQ can run on top of XMPP, on top of SSL.
