Subject RE: Using Reloadable properties
Date Sat, 28 Apr 2007 21:26:44 GMT

Per Rel 1.4 Notes:

File-based configurations with a reloading strategy did not work well 

  together with CombinedConfiguration because the reloading strategy is
only 

  checked when its associated configuration is accessed (which does not 

  happen when only the combined configuration is queried). As a
workaround 

  CombinedConfiguration now provides the boolean forceReloadCheck
property. 

  If this is set to true, all contained configurations will be triggered
when 

  a property is queried. This will cause a reload if necessary. Issue: 

  CONFIGURATION-240.

 

But I do not see such a method in java docs.

 

Also, when I define my Config file as below, I get the following error :

 

<!-- Test configuration definition file that demonstrates complex
initialization -->

<configuration>

  <header>

    <result delimiterParsingDisabled="true" forceReloadCheck="true">

      <expressionEngine
config-class="org.apache.commons.configuration.tree.xpath.XPathExpressio
nEngine"/>

    </result>

  </header>

  <override>

    <properties fileName="test_reloadable.properties"
throwExceptionOnMissing="false"

      config-name="propertiesTest" config-optional="true">

      <reloadingStrategy refreshDelay="1000"

 
config-class="org.apache.commons.configuration.reloading.FileChangedRelo
adingStrategy"/>

    </properties>

    <properties fileName="test2.properties"
throwExceptionOnMissing="false"

      config-name="properties2" config-optional="true">

      <reloadingStrategy refreshDelay="1000"

 
config-class="org.apache.commons.configuration.reloading.FileChangedRelo
adingStrategy"/>

    </properties>

  </override>

</configuration>

ConfigurationFactory does not support specifying reloading strategies. 

You have to use DefaultConfigurationBuilder instead. Details can be 

found in the user guide [1]. There is also an example of defining a 

reloading strategy.
