Subject [jira] Commented: (AMQ-1609) STOMP messages only support properties with data type String
Date Sat, 12 Apr 2008 13:05:43 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-1609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42231#action_42231
] 

Timothy Bish commented on AMQ-1609:
-----------------------------------

I'd think we'd want some sort of versioning of the Stomp protocol so that clients can know
what they are talking when communicating with a broker.  For instance if the ActiveMQ CPP
client was to receive a stomp frame with this property encoding we'd probably throw all sorts
of exceptions which would not be good.  I'd think if we did something like this we'd need
to also provide some sort of wire format negotiation mechanism so that a client can tell the
broker whether or not it can handle v1.1 typed properties or not.

> Currently the STOMP connector seems to support only string type message properties. 
> As an effect, subscription selectors like color = 'blue' AND weight > 2500 will not
work (if the message has been sent using STOMP, the weight property will be a string).
> I suggest to implement typed properties in the Stomp protocol which could be serialized
in a platform-independent way.
> In addtion , if I understand the OpenWire documentation correctly, the OpenWire protocol
supports some simple datatypes, but not - for example - Date, which would be easy to map to
a long value.
