XML : Java XStream cannot find class in Maven directory

I am using XStream and when I run my application for a module called Webserver directory: org/westbank/webserver

But if I have it in certain other modules, it parses fine without the error.. I am confused. Even if i make a new module and try it, I get the error, but most of the other modules I have work if I add TestService to it and load it from that path.

My XML:

  <XML>   <service class = "org.westbank.webserver.authentication.TestService">      <name>Test</name>      <identifier>14</identifier>      <vital>true</vital>   </service>  </XML>    

The Error:

  Exception in thread "main"  com.thoughtworks.xstream.converters.ConversionException:   ---- Debugging information ----  cause-exception     :     com.thoughtworks.xstream.mapper.CannotResolveClassException  cause-message       : org.westbank.webserver.authentication.TestService  class               : org.westbank.configuration.XMLConfiguration  required-type       : org.westbank.configuration.XMLConfiguration  converter-type      :     com.thoughtworks.xstream.converters.reflection.ReflectionConverter  path                : /XML/service  line number         : 2  version             : 1.4.9  -------------------------------
