The general functionality of file-based payload logging is provided for Web Service endpoints in form of two CXF interceptors located within the package, which have to be deployed on the endpoints:

  • .InPayloadLoggerInterceptor for inbound messages
  • .OutPayloadLoggerInterceptor for outbound message

In addition to the base expression placeholders, the following one is defined:

Value Name Value Type Description
partialResponse boolean true when the currently handled message represents a WS-Addressing asynchronous acknowledgement (HTTP code 202). This gives a means to distinguish between such acknowledgement messages and “normal� messages which have the same sequence IDs


This is a Spring configuration fragment that defines a set of parameterized interceptor beans:

    <bean id="logFileNamePrefix" class="java.lang.String">
        <constructor-arg value="#{systemProperties['IPF_LOG_DIR']}/[processId]/[date('yyyyMMdd-HH00')]/[sequenceId]" />

    <bean id="serverInLogger" class="">
        <constructor-arg value="#{@logFileNamePrefix}-server-in.txt" />

    <bean id="serverOutLogger" class="">
        <constructor-arg value="#{@logFileNamePrefix}-server-out[partialResponse ? '-partial' : ''].txt" />

In this example, a common prefix for log file names is defined. Referencing the JVM property IPF_LOG_DIR gives an additional possibility for path customization by the user. The serverOutLogger interceptor is configured to distinguish between “normal� outbound messages and WS-Addressing asynchronous acknowledgements — the latter will be stored in files with a special suffix “-partial�.

The endpoint URI which uses these interceptors can look like:

    from("xca-iti39:iti39service" +
         "?inInterceptors=#serverInLogger" +
         "&inFaultInterceptors=#serverInLogger" +
         "&outInterceptors=#serverOutLogger" +

Custom file name expression resolvers

The logger beans in the example above implicitly use the Spring Expression language, which requires you to add the following runtime dependency to your pom.xml file:


You can also provide your own implementation of org.openehealth.ipf.commons.ihe.core.payload.ExpressionResolver and pass an instance with the constructors of the payload loggers instead.
