Logging is activated by use of separate in/out interceptors that can be attached to the client and/or service as required. These interceptors can be specified either programmatically (via Java code and/or annotations) or via use of configuration files.</p><p>Configuration files are probably best. They offer two benefits over programmatic configuration:</p><ol><li>Logging requirements can be altered without needing to recompile the code</li><li>No Apache CXF-specific 
 APIs need to be added to your code, which helps it remain interoperable with other JAX-WS compliant web service stacks</li></ol><p>Enabling message logging through configuration files is shown <a shape="rect" href="http://cxf.apache.org/docs/configuration.html">here</a>.</p><p>For programmatic configuration, the logging interceptors can be added to your service endpoint as follows:</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
