PropertyPlaceholderConfigurer and VelocityConfigurer

[chacs]

Hi,

I am having problem that placeholders in velocity.properties are not being replaced.

in applicationContext.xml:

<bean id="propertyPlaceholderConfigurer" class="org.spr...PropertyPlaceholderConfigurer">
  <property name="location"><value>/WEB-INF/app.properties</value></property>
</bean>

in some-servlet.xml:

<bean id="velocityConfig"class="org.spr...VelocityConfigurer">
  <property name="configLocation"><value>/WEB-INF/velocity.properties</value></property>
</bean>

/WEB-INF/app.properties:

velocity.file.resource.loader.modificationCheckInterval=0

/WEB-INF/velocity.properties:

file.resource.loader.modificationCheckInterval=${velocity.file.resource.loader.modificationCheckInterval}

The place holder ${velocity.file.resource.loader.modificationCheckI nterval} was not replaced by 0 (got exception from VelocityConfig trying to convert that ${ve...} string to a number)

I have tried a few things without success:

1. move the PropertyPlaceholderConfigurer from applicationContext.xml to some-servlet.xml

2. use a PropertiesFactoryBean instead of setting the configLocation on VelocityConfigurer (same result):

<bean id="velocityConfig"class="org.spr...VelocityConfigurer">
  <property name="velocityProperties">
    <bean class="org.spr...PropertiesFactoryBean">
      <property name="location">/WEB-INF/velocity.properties</property>
    </bean>
  </property>
</bean>

any help ?

thanx.

The PropertyPlaceholderConfigurer is meant to use variables instead of property values in the same app context. So, it doesn't change the value of a file included to be interpreted by a bean.
However, you can dispatch toward one velocity configuration or another, it is the right level of abstraction.
