First, why not do
<bean id="configurationBuilder"
class="org.apache.commons.configuration.DefaultConfigurationBuilder">
<property name="fileName" value="test-config-xml.xml"/>
</bean
<bean id="appConfig" factory-bean="configurationBuilder" factory-
method="getConfiguration"/>
Then declare your component to take a CombinedConfiguration instead of
the builder.
Next, you've supplied the constructor for a class named FtpEdt yet
your stack trace shows the failure in a class named Email. What is
that class doing?

I'm using Spring to autowire things together; in my Spring test-

</bean>
In test-config-xml.xml I have
<?xml version="1.0" encoding="ISO-8859-1" ?>
<configuration>
<xml
config-name="ftp"
fileName="properties/ftp.xml"
/>
<xml
config-name="email"
fileName="properties/email.xml"
/>
</configuration>
And ftp.xml contains
<?xml version="1.0" encoding="ISO-8859-1" ?>
<ftp>
<server>${ftp.server}</server>
<login>${ftp.login}</login>
<password>${ftp.password}</password>
<siteCmd>${ftp.siteCmd}</siteCmd>
</ftp>
The ${} placeholders are replaced by maven when I run my tests. The
email.xml file contains similar entries.
In my class that uses the DefaultConfigurationBuilder, it's injected
by Spring in its constructor:
@Autowired
public FtpEdt(final DefaultConfigurationBuilder configBuilder)
throws ConfigurationException {
super();
final CombinedConfiguration combinedConfig =
configBuilder.getConfiguration(true);
final Configuration config =
combinedConfig.getConfiguration("ftp");
this.server = config.getString("server");
if (this.server == null)
throw (new IllegalStateException("server not set"));
The problem is when the Email class's constructor is called, which
looks very similar, it blows up on the
configBuilder.getConfiguration(true); with
Caused by:
org.apache.commons.configuration.ConfigurationRuntimeException: A
configuration with the name 'ftp' already exists in this combined
configuration!

configuration-1.5.jar:1.5]

[classes/:na]
...
So I guess I don't understand how to use the CombinedConfiguration
and the DefaultConfigurationBuilder; can someone give me some hints
for how to do this?
Thanks
