RE: Configuration of transportConnectors, persistenceAdapter beans
Thanks James :)
I modified activemq.xml as below (Im using RC1):
<?xml version="1.0" encoding="ISO-8859-1"?>
<beans xmlns="http://activemq.org/config/1.0">
<bean id="configurer1"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfi
gurer">
<property name="location">
<value>classpath:context/server.properties</value>
</property>
</bean>
<broker useJmx="true" name="JMSServer">
<persistenceAdapter>
<journaledJDBC journalLogFiles="5"
dataDirectory="../activemq-data"/>
</persistenceAdapter>
<transportConnectors>
<transportConnector uri="tcp://${jms.server.hostname}:61616"/>
</transportConnectors>
</broker>
</beans>
server.properties file has the line: jms.server.hostname=localhost
There is another xml file that has the following bean definition
<bean id="activeMqBroker"
class="org.apache.activemq.xbean.BrokerFactoryBean">
<property name="config" value="classpath:activemq.xml"/>
<property name="start" value="true"/>
</bean>
My spring beans depend on the above bean with the bean id
"activeMqBroker".
When I ran the application I got the following stack trace. I wonder
where from this 'value' class appeared.
Is spring trying to parse "tcp://${jms.server.hostname}:61616" before it
can substitute jms.server.hostname?

Under the covers we're using Spring so you should be able to use a
Spring BeanPostProcessor to resolve any properties you like - e.g. add
this to the top of your file inside <beans>
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfi
gurer"/>

Re: Configuration of transportConnectors, persistenceAdapter beans
Posted by Adrian Co <ac...@exist.com>.
Hi,
I don't know if this would help, but i tried chaging:
<bean id="configurer1"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>classpath:context/server.properties</value>
</property>
</bean>
to
<bean id="configurer1"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:context/server.properties">
</property>
</bean>
and it worked for me.
Not sure though if this is by design or a bug. Maybe you could ask the spring guys. Probably something to do with location being an Object of type File. :-)
