Well, that's the problem. When we use jms.useAsyncSend in the connection URI with the failover transpoert we can't even start the JMS client. It hangs when it's trying to create the connection to the broker. We are using Active-MQ 5.0.0. These are the errors we see in the logs pertaining to ActiveMQ
*DEBUG 08:06:34.296,ActiveMQ Task,(org.apache.activemq.transport.failover.FailoverTransport:136)> Connect fail to: tcp://localhost:61616?jms.useAsyncSend=true&wireFormat.maxInactivityDuration=-1, reason: java.lang.IllegalArgumentException: Invalid connect parameters: {jms.useAsyncSend=true} *DEBUG 08:06:34.296,ActiveMQ Task,(org.apache.activemq.transport.failover.FailoverTransport:152)> Waiting 10 ms before attempting connection. which is what made me think that useAsyncSend is not possible to use with failover. If I remove the failover transport client is able to connect successfully but then we lose the features we wanted with failover. The connection URI looks like this failover:(tcp://localhost:61616?jms.useAsyncSend=true&wireFormat.maxInactivityDuration=-1) thanks jaya James.Strachan wrote: > > 2008/5/9 jaya_srini <[EMAIL PROTECTED]>: >> >> Thanks so much for the responses.
