Subject [jira] Commented: (AXIS2-3662) Can't use JMS transport from axis2.war on WebSphere Application Server 6.1
Date Tue, 01 Apr 2008 08:42:25 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-3662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12584054#action_12584054

Asankha C. Perera commented on AXIS2-3662:
------------------------------------------

The original post above stated that:

>My question is that why is axis2 not compliant with this specification? Also what options
do i have for using the jms transport with axis2 in WAS

Axis2 is targeted for the Web container of a J2EE server, and the typical restrictions that
applies for the EJB containers were not applicable to the Web container earlier

>Initial research shows the following possibilities:
>1) Use MDB's (not ideal)
>2) Change the axis2 code itself and make a synchronous MessageConsumer.receive call and
poll for messages

Axis2 needs to start/stop listening on JMS destinations as new services are deployed/un-deployed,
and thus I do not think the use of MDB's is going to be a proper solution. I am not in favour
of using a polling mechanism either - as JMS needs to be a high performance and time-critical
transport - unlike the File/Mail transports etc, where polling is acceptable and/or relevant

>Can anyone advice on the best approach here? And also will axis2 become compliant with
the J2EE 1.4 spec in the future?

I am looking at this, and at the same time thinking about how we should support transactions
with JMS.. so any comments from the community is welcome

> This means that the only way of deploying Axis2 with JMS transport on WAS is to use the
standalone axis server. This works, but a deployment within the application server would be
greatly preferable.
