Fuse ESB - Configuring Web Service Endpoints

Logging Message Content

You can log the content of the messages that are sent between a service and a consumer. For example, you might want to log the contents of SOAP messages that are being sent between a service and a consumer.

Configuring message content logging

To log the messages that are sent between a service and a consumer, and vice versa, complete the following steps:

Adding the logging feature to an endpoint

Add the logging feature your endpoint's configuration as shown in Example 5.11.

Example 5.11. Adding Logging to Endpoint Configuration

<jaxws:endpoint ...>
  <jaxws:features>
    <bean class="org.apache.cxf.feature.LoggingFeature"/>
  </jaxws:features>
</jaxws:endpoint>

The example XML shown in Example 5.11 enables the logging of SOAP messages.

Adding the logging feature to a consumer

Add the logging feature your client's configuration as shown in Example 5.12.

Example 5.12. Adding Logging to Client Configuration

<jaxws:client ...>
   <jaxws:features>
      <bean class="org.apache.cxf.feature.LoggingFeature"/>
    </jaxws:features>
</jaxws:client>

The example XML shown in Example 5.12 enables the logging of SOAP messages.

Set logging to log INFO level messages

Ensure that the logging.properties file associated with your service is configured to log INFO level messages, as shown in Example 5.13.

Example 5.13. Setting the Logging Level to INFO

.level= INFO
java.util.logging.ConsoleHandler.level = INFO

Logging SOAP messages

To see the logging of SOAP messages modify the wsdl_first sample application located in the InstallDir/samples/wsdl_first directory, as follows:

Add the jaxws:features element shown in Example 5.14 to the cxf.xml configuration file located in the wsdl_first sample's directory:

Example 5.14. Endpoint Configuration for Logging SOAP Messages

<jaxws:endpoint name="{http://apache.org/hello_world_soap_http}SoapPort"
                createdFromAPI="true">
  <jaxws:properties>
    <entry key="schema-validation-enabled" value="true" />
  </jaxws:properties>
  <jaxws:features>
    <bean class="org.apache.cxf.feature.LoggingFeature"/>
  </jaxws:features>
</jaxws:endpoint>

The sample uses the default logging.properties file, which is located in the InstallDir/etc directory. Make a copy of this file and name it mylogging.properties.
In the mylogging.properties file, change the logging levels to INFO by editing the .level and the java.util.logging.ConsoleHandler.level configuration properties as follows:
```
.level= INFO
java.util.logging.ConsoleHandler.level = INFO
```

Start the server using the new configuration settings in both the cxf.xml file and the mylogging.properties file as follows:

Platform	Command
Windows	`start java -Djava.util.logging.config.file=%CXF_HOME%\etc\mylogging.properties demo.hw.server.Server`
UNIX	`java -Djava.util.logging.config.file=$CXF_HOME/etc/mylogging.properties demo.hw.server.Server &`

Start the hello world client using the following command:

Platform	Command
Windows	`java -Djava.util.logging.config.file=%CXF_HOME%\etc\mylogging.properties demo.hw.client.Client .\wsdl\hello_world.wsdl`
UNIX	`java -Djava.util.logging.config.file=$CXF_HOME/etc/mylogging.properties demo.hw.client.Client ./wsdl/hello_world.wsdl`

The SOAP messages are logged to the console.
