ApacheCommonsConfigPropertySource for using Apache Commons Config with Spring Property Sources

ApacheCommonsConfigPropertySource.java

package com.bowerstudios.config;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import org.apache.commons.configuration.Configuration;
import org.springframework.core.env.EnumerablePropertySource;

/**
 * Allow use of Apache Commons Configuration Objects as Spring PropertySources
 */
public class ApacheCommonsConfigPropertySource extends
		EnumerablePropertySource<Configuration> {

	public ApacheCommonsConfigPropertySource(final String name,
			final Configuration source) {
		super(name, source);
	}

	@Override
	public Object getProperty(final String arg0) {
		return source.getProperty(arg0);
	}

	@Override
	public String[] getPropertyNames() {
		final List<String> keys = new ArrayList<String>();
		final Iterator<String> keysIterator = source.getKeys();
		while (keysIterator.hasNext()) {
			keys.add(keysIterator.next());
		}
		return keys.toArray(new String[keys.size()]);
	}
}

Still works with commons-configuration 2, just update the imports.
