Dynamic Changes to Properties File When Using Bridge Property Placeholder

[pberkman]

I am using the
org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer to
parameterize most of the varible-configuration in the Camel Contexts/Routes
as such:

<bean id="bridgePropertyPlaceholder"
class="org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer">
<property name="location" value="file:nextgate/ms/ngmsroute.properties"/>
</bean>

Unfortunately, the default is to cache all the property values. So, I have
to reload the app every time I need to change anything like a simple port
number in one of the adapters, etc.

Question: is there a way to configure the Bridge Property Placeholder so
that it will check the modify time of the properties file and reload if
necessary?

thanks!

Which runtime do you use?
In Karaf and ServiceMix you use the OSGI ConfigAdmin service which does
this for you. For free... ;-)
And you can configure the properties in a nice console too. The changed
property will be also flushed into the config file.

Best,
Christian

using Glassfish 3.1.2, so they have OSGI, but that is not a trivial change -
something I need to do in the future for certain, but not just for this
functionality... any other options?

The bridge is an adapter to the Spring property configurer. So check
the Spring docs what they offer from options. Maybe there is a cache
option you can turn off. etc Or maybe from JMX force a re-load of the
file etc.
