Logging Messages

CXF includes two logging interceptors which output the incoming/outgoing messages to the Java log. To enable, you need to add these interceptors to your endpoint.uses Java SE Logging for both client- and server-side logging of SOAP requests and responses. 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 or via use of configuration files.

For programmatic configuration, the logging interceptors can be added to your service endpoint as followsServer-side, if you have a JAX-WS endpoint, you would want to do this:

import javax.xml.ws.Endpoint;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.EndpointImpl;

EndpointImpl ep = (EndpointImpl) Endpoint.publish("http://localhost/service", service);

ep.getServer().getEndpoint().getInInterceptors().add(new LoggingInInterceptor());
ep.getServer().getEndpoint().getOutInterceptors().add(new LoggingOutInterceptor());

...

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;

public class WSClient {
    public static void main (String[] args) {
        MyService ws = new MyService();
        MyPortType port = ws.getPort();
        
        Client client = ClientProxy.getClient(port);
        client.getInInterceptors().add(new LoggingInInterceptor());
        client.getOutInterceptors().add(new LoggingOutInterceptor()); 
        
        // make WS calls...

However, you will probably want to use configuration files for this. They offer two benefits over programmatic configuration:

1. Logging requirements can be altered without needing to recompile the code
2. 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.

Enabling message logging through configuration files is shown hereYou can also enable message logging through CXF configuration.

Configure logging levels.

CXF uses Java SE Logging. In the /etc folder of the CXF distribution there is a sample Java SE logging.properties file you can use to configure logging. For example, if you want to change the console logging level from WARNING to FINE, you need to update two properties in this logging.properties file as below:
