RE: Route Dependency in XML DSL + JPA
Hello,
Thanks for your reply. This strategy appears not to work. Using the jpa
component in the to endpoint tries to store the entity in the message
body into the db. This results in a null pointer. I am trying to
retrieve entities from the db using jpa.
So once route A completes, route B should use the jpa component to get
the entities from the db.
Any other ideas would be appreciated. I might have to write a custom
bean, but I thought Camel could handle this. Seems like a use case.
<route id ="A">
<from uri="quickfix:config" />
<!-- On login, create MD Request -->
<filter>
<simple>${header.EventCategory}
=='SessionLogon'</simple>
</filter>
<to uri="direct-vm:route-b"/>
</route>
<route id="B">
<from uri="direct-vm:route-b"/>
<to
uri="jpa://{{app.jpa.cdx.entity}}?consumeDelete=false&consumer.query={{a
pp.sql.included.cds}}" />
<bean ref="SecDefinitionFactory" method="create"/>
<bean ref="MarketDataRequestFactory" method="create"/>
<to uri="quickfix:config?....." />
</route>

sorry - I missed the XML prerequisite.
would it be an option to connect route A to B using a direct endpoint
e.g.:
<route id ="A">
<from uri="quickfix:config" />
<!-- On login, create MD Request -->
<filter>
<simple>${header.EventCategory}
=='SessionLogon'</simple>
</filter>
<to uri="direct-vm:route-b"/>
</route>
<route id="B">
<from uri="direct-vm:route-b"/>
<to
uri="jpa://{{app.jpa.cdx.entity}}?consumeDelete=false&consumer.query={{a
pp.sql.included.cds}}" />
<bean ref="SecDefinitionFactory" method="create"/>
<bean ref="MarketDataRequestFactory" method="create"/>
<to uri="quickfix:config?....." />
</route>

I have the same use case as you - upon completion of route 'A', signal
route 'B' to perform a one-time read of the DB. (by "one-time", I
mean once per-signal from route 'A'). for the custom poller see my
response to your other email with subject "JPA Component behavior",
which has the custom poll strategy attached. Your XML example is
attached.
