method-invoking Spring bean - java

I've declared the following bean in my Spring config
<bean id="templateCacheClearingTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">
<property name="delay" value="5000" />
<property name="period" value="5000" />
<property name="timerTask">
<bean class="org.springframework.scheduling.timer.MethodInvokingTimerTaskFactoryBean">
<property name="targetObject" ref="templateMailService" />
<property name="targetMethod" value="clearCache" />
</bean>
</property>
</bean>
This should cause the clearCache() method of the templateMailService bean to be invoked every 5000ms, but nothing appears to be happening. Am I missing something?
Cheers,
Don

I think you need:
<bean id="timerFactory" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref bean="templateCacheClearingTask"/>
</list>
</property>
</bean>
In addition to what you already have.

ActiveMQ Data persistent Issue in Java Spring

I have an application which uses embedded activeMQ 5.11. At the start of the application it creates activemq-data\producerBroker\KahaDB folder at the class path location. I do want to change the location but spring.xml doesn't take a location.
Spring.xml as given,
<bean id="producerBroker" class="org.apache.activemq.broker.SslBrokerService">

g.ClassNotFoundException: org.apache.activemq.store.kahadaptor.KahaPersistenceAdapter"
Anyone has experience in the directory change in activeMQ 5.11 in java spring?
The destination of the persistence location must be defined at the broker level.
The kahaPersistenceAdapter (which was file based) was removed with version 5.9. You should use the kahaDB.
kahaDB - uses KahaDB an embedded lightweight non-relational database
<broker brokerName="broker" persistent="true" useShutdownHook="false">
<transportConnectors>
<transportConnector uri="tcp://localhost:61616"/>

How to use SpEL in Spring?

I have declare bean like these:
<bean id="kenny"
class="com.springinaction.springidol.Instrumentalist">
<property name="song" value="Price Tag"></property>
<property name="age" value="27"></property>
<property name="instrument">
<bean class="com.springinaction.springidol.Saxophone"/>
</property>
</bean>
<bean id="carl"
class="com.springinaction.springidol.Instrumentalist">
<property name="song" value="#{kenny.song}" />
<property name="instrument">
<bean class="com.springinaction.springidol.Saxophone"/>
</property>
</bean>
Why the song property of carl is "#{kenny.song}" not "Price Tag"?
What am I missing to use SpEL in Spring?

ReloadingPropertyPlaceholderConfigurer

For some reason the ReloadablePropertiesFactoryBean doens't seem to do what I expect. When I change a property in the test.properties file I get a log message saying:
9979 [timer] INFO com.krest.core.properties.ReloadablePropertiesFactoryBean - Reloading Properties...
But for some reason nothing happens. The old property value is still set on my test bean. Does anybody know why this is? I use Spring 3 and my configuration looks like this:
<bean id="configproperties"
class="com.krest.core.properties.ReloadablePropertiesFactoryBean">
<property name="location"
value="classpath:test.properties" />
</bean>
<bean id="propertyConfigurer"

<property name="reloadingPlaceholderSuffix" value="}" />
</bean>
<bean id="mybean" class="nl.mycompany.TestBean">

</bean>

Validate format parameter via config in Spring MVC

Here is my situation:
I have my mvc-config.xml file for my web service set up to have JSON as the default media type. I also have favorParameter for the ContentNegotiatingViewResolver as true. Additionally, I have useNotAcceptableStatusCode as true so that not accepted formats will return a 406.
My question is: Is there a way, in the config, to trigger the 406 status code when someone passes in an unacceptable format parameter (format=foo)? Or must that be done with code?
Here is the config file:

ContentNegotiatingViewResolver doesn't seem to support such behaviour. For now, I think your best bet is to subclass it and override the getMediaTypeFromParameter() method to throw an exception if the media type is not supported.
You can throw any RuntimeException from that method, and if you annotate the exception class with #ResponseStatus, you can control the HTTP response code, e.g.
#ResponseStatus(HttpStatus.NOT_ACCEPTABLE)
public class FormatNotSupportedException extends RuntimeException {
}
In the longer term, I strongly encourage you to file an issue with http://jira.springsource.org, asking for such functionality to be added to ContentNegotiatingViewResolver. They should be able to add this as an optional behavioural parameter. It's requests like these that mean Spring keeps getting better.
