Subject [jira] [Commented] (AMQ-4468) TimeStampPlugin doesn't work with Stomp
Date Mon, 15 Apr 2013 22:50:16 GMT


Erik commented on AMQ-4468:

My test code that verifies the problem is written in php. I am not a  java developer. I do
not have the ability to create a JMS unit test. Do you want a tar file of php? It's a very
simple test. Use a language binding other than java JMS and send a message.  Perhaps NMS?
The "timestamp" header is added. If a timestamp existed, it is still changed. This is the
essence of the bug.

>             Fix For: 5.8.0
> Stomp producers cannot set the JMSTimestamp or timestamp header. Activemq always adds
a timestamp header and overrides a set value. Therefore, the expires header cannot be recalculated
according to Activemq time according to the description for TimeStampPlugin. TimeStampPlugin
works for JMS producers because the JMSExpiration UTC can be adjusted up/down according to
the difference between JMSTimestamp and Activemq UTC.
> Example:
> ActiveMQ time is 2pm UTC
> Stomp producer time is 1:03pm UTC.
> Stomp expires time is 1:03pm + 15 minutes: 1:18pm UTC.
> ActiveMQ will throw this message away with TimeStampPlugin enabled.
> ActiveMQ will deliver this message for a JMSProducer.
> Recommendation:
> 1)
> ActiveMQ should allow Stomp producers to set a timestamp or JMSTimestamp header.
> if( Stomp Message Timestamp Header ) {
> use header
> }
> else {
> add timestamp header
> }
> 2)
> Add the disableTimeStampsByDefault=true feature to the stomp protocol URI.
