the Commons Configuration problem

[kkk]

Hi:
I found the Commons Configuration  can do most of read configuraion
job for me ,so I want to have a try.
But I am not sure the Commons Configuration how to read the file(for
example a xml file), is it a Singleton?  Since if not, I think I
should build a Singleton class to save the properties read by the
Commons Configuration, if so , I can use the Commons Configuration
directly.
Thanks.

Have you looked at http://commons.apache.org/configuration/userguide/howto_xml.html#Accessing_properties_defined_in_XML_documents?
  If the user's guide doesn't provide all the information you are  
looking for you might want to describe your use case so others can  
give you advice on how to do it.

In answer to your specific question, no it is not a singleton. But if  
your application keeps a reference to the configuration object you can  
retrieve the properties as often as needed. If your application needs  
to allow the configuration to be updated without restarting the  
application you should not transfer the data to other objects.  
Instead, use a reloading strategy and get the properties from the  
configuration every time they are needed.

Thanks , I dont need the update, so I think I can use a extra object
to save the data from the property file.

AFAIK no such thing exists. I would guess the xwork copied/repackaged
org.apache.commons.lang.StringUtils.

Looking at the xwork pom[1], it looks like thats what they've done
with the shade plugin[2]:

[1] http://svn.opensymphony.com/svn/xwork/trunk/core/pom.xml
[2] http://maven.apache.org/plugins/maven-shade-plugin/
