How to set configuration information in xbean.xml dynamically based
on message content
Iam using servicemix-http BC i need to pass the authentication information
dynamically i.e, the username and password will contain in the incoming
message itself
I should be able to pass the authentication info like this in xbean.xml
<basicAuthCredentials>
<username>${user}</username>
<password>${password}<password>
</basicAuthCredentials>
where user,password will contain in the incoming message
Is there any possibility of making using of POJO support ?, if it is how to
do that?

Arif,
One possible solution would be to add a servicemix-lwcontainer SU to your
application and build a simple POJO which adds the properties and then
forwards the message to your topic. Look at
http://incubator.apache.org/servicemix/pojo-support.html for more
information about how to do it...

Thank you Gert Vanthienen for quick response,
Iam having the similar but another requirement, iam using topic to place
the messages and the clients will read messages from this topic.
Requirement is before placing the message inthe topic i should be able to
read incoming message information and set some properties of the
message(Authentication information for the clients) so that the message will
be read by the intended client
Please provide some example code this is a very quick requirement tobe
implemented, a very quick response will be a great help tome.
Thanks in advance.

Re: changing jms consumer priorities at runtime
Posted by Dominique DE VITO <do...@thalesgroup.com>.
I understand your response like this:
- it's a priority defining concurrency between possible consumers of the
*same* messages,
- it's NOT a priority defining (CPU) concurrency between all the
consumers (then, my use case could not be implemented)
Is it correct ?

Re: changing jms consumer priorities at runtime

If i understand correctly, the consumer priority is only used when choosing
a consumer
to dispatch the message to. It won't affect the priority between messages,
which
is from what you want if I understand correctly.

Re: changing jms consumer priorities at runtime
Posted by Dominique DE VITO <do...@thalesgroup.com>.
Yes, the priority can't be changed at runtime in ActieMQ
But I think it could be done in SMX.
A "queue" looks like created for *each* StandardConsumerProcessor.poll()
method call:
destination = session.createQueue(endpoint.getJmsProviderDestinationName());
While changing "JmsProviderDestinationName" property value, from
"TEST.QUEUE?consumer.prority=10" string value to
"TEST.QUEUE?consumer.prority=20" string value, the consumer's priority
might be changed, I think, inside SMX.
Does it make sense ?
Here is the use case:
- my own business flows are from/to JMS endpoints, with various
intermediate steps,
- I want to modify flow priorities at business level
- the simplest way I have found is to modify JMS consumer priority to
change the associated business flow priority.

Re: changing jms consumer priorities at runtime
Posted by Guillaume Nodet <gn...@gmail.com>.
I don't think the priority can be changed at runtime in ActiveMQ.
This will need to close and recreate a new consumer, i.e. stop / restart
the endpoint / SU / SA ...
Another problem is that this is an ActiveMQ specific property ...
What's your use case for changing the consumer prioirity (and not the
message priority) at runtime ?

changing jms consumer priorities at runtime
Posted by Dominique DE VITO <do...@thalesgroup.com>.
I have some questions about defining/changing a JMS consumer's priority
inside ServiceMix.
* Priority defined at startup time
Possible through http://activemq.apache.org/consumer-priority.html ?
Is it correct ?
* Priority defined dynamically
It is not possible to change JMS consumer's priority at runtime inside SMX.
Is it correct ?
What about the following solution: exposing a "priority" field inside
JmsConfigurationMBean class and using this priority when creating a
MessageConsumer ?
Thanks.

Re: How to set configuration information in xbean.xml dynamically
based on message content
Posted by Gert Vanthienen <ge...@skynet.be>.
L.S.,
The authentication happens in the
org.apache.servicemix.http.processors.ProviderProcessor class. In the
process() method you will find the basic authentication credentials being
applied.
I think you can extend org.apache.servicemix.http.BasicAuthentication to
support Expression attributes for name and password. You will probably also
have to change the applyCredentials() method signature, to add an additional
parameter -- the message itself -- which you will need to resolve the
expressions. You can then reuse <sm:xpath /> to specify the expression in
your xbean.xml file.
I hope this already gets you started. Just let me know if you need any more
help...
I'm a bit confused about your reference to the other forum topic. Do you
also want to use this feature? Doesn't the proposed solution in this thread
work?
