camel quartz

[marcin80 <mt...@gmail.com>]

Hi

I would like to know how to create quartz jobs dynamically? My case is
following:
I have a message consumer witch consume messages from queue and each message
should be proces at specific time defined in message property. So I would
like use somethig like this:

<route>
 <from uri="activemq:queue:test"/>
 <!-- here I would like to create quartz jobs for each message triggering
message processing in specific time but I don't know how to do it (maybe it
is impossible?)-->

</route>

Can I do it?

Cheers,
Marcin

Ah okay then I assume you can use some sort of persistent quartz to
store the trigger time and the message content.
Then you need a database to store that. But then quartz should be able
to schedule and trigger those jobs accordingly.

I was just looking if you would keep that info in memory only and thus
suffer from lost messages in case of crash etc.
So keeping the messages on the JMS Broker would then be a better choice.

But the persistent of quartz will do as well.

Hi Claus, 

Thank you  for your response.

Time interval will be changeable for each task but range is 1 day - 1 week. 

Cheers,
Marcin

How long time in the future should those tasks be executed? It will
assume its better to keep the messages in the JMS Broker until the
time is due before they are visible for the consumers. JMS have such a
feature. Cant remember exact details about it.

Anyway you can use regular Quartz to schedule tasks. So just route to
a bean or Processor and do the code in Java to schedule it with
Quartz.
To continue routing the message from that task you can use
ProducerTemplate to send it back to Camel.

We do however have a ticket about being able to send a message to
camel-quartz endpoint and have it schedule the tasks for the future
and which destination to send to
https://issues.apache.org/activemq/browse/CAMEL-1185

Use the JIRA voting system to let us know which tickets is important
for the community.

And as always we love contributions so if anyone is up for it then try
make that feature and submit patches to back to Apache.
