LoggerContext is the context for logback-classic whereas RequestLogImpl
*is* the context for logback-access+Jetty.  You need to set requestLog (of type RequestLogImpl) as the context for components such as RollingFileAppender and TimeBasedRollingPolicy. By the way, all logback components must be started. Otherwise, they will not work.

As such, here a revised version which should work better. Beware, I have not tested this code and it may still contain some wrinkles. Without further ado here is the code:

  RequestLogImpl requestLog = new RequestLogImpl(); // implements Context

        ch.qos.logback.access.PatternLayoutEncoder encoder = new ch.qos.logback.access.PatternLayoutEncoder();
        encoder.setContext(requestLog);
        encoder.setPattern("combined");
        encoder.start(); // // components must be started

        RollingFileAppender<IAccessEvent> appender = new RollingFileAppender<IAccessEvent>();
        appender.setContext(requestLog); // requestLog is the context
        appender.setName("REQUESTLOG");
        appender.setFile("/bps/log/request/myrequest.log");
        appender.setEncoder(encoder);


        TimeBasedRollingPolicy<IAccessEvent> timePolicy = new TimeBasedRollingPolicy<IAccessEvent>();


timePolicy.setFileNamePattern("/bps/log/archive/request/my_request_%d{yyyy-MM-dd}_%d{HH_mm_ss,aux}.log.zip");
        timePolicy.setContext(requestLog); // requestLog is the context
        timePolicy.setMaxHistory(30);
        timePolicy.setTimeBasedFileNamingAndTriggeringPolicy(new StartupTimeBasedTriggeringPolicy<IAccessEvent>());
        timePolicy.setParent(appender);
        timePolicy.start(); // components must be started

        appender.setRollingPolicy(timePolicy);
        appender.setTriggeringPolicy(timePolicy);

        appender.start(); // // components must be started
        requestLog.addAppender(appender);

Let us know how it goes.

This does not work (it archives etc, but never any contents in the file) :

        LoggerContext loggerContext =
LoggerContext.class.cast(LoggerFactory.getILoggerFactory());

        RollingFileAppender<IAccessEvent> appender = new
RollingFileAppender<>();
        appender.setName("REQUESTLOG");
        appender.setFile("/bps/log/request/myrequest.log");
        TimeBasedRollingPolicy<IAccessEvent> timePolicy = new
TimeBasedRollingPolicy<>();

timePolicy.setFileNamePattern("/bps/log/archive/request/my_request_%d{yyyy-MM-dd}_%d{HH_mm_ss,aux}.log.zip");
        timePolicy.setContext(loggerContext);
        timePolicy.setMaxHistory(30);
        timePolicy.setTimeBasedFileNamingAndTriggeringPolicy(new
StartupTimeBasedTriggeringPolicy<IAccessEvent>());
        timePolicy.setParent(appender);
        appender.setRollingPolicy(timePolicy);
        appender.setTriggeringPolicy(timePolicy);
        PatternLayoutEncoder encoder = new PatternLayoutEncoder();
        encoder.setPattern("combined");
        appender.setEncoder(encoder);
        RequestLogImpl requestLog = new RequestLogImpl();
        requestLog.addAppender(appender);

    Hi Jan-Olav,

    It's not possible to tell without seeing the code in question. Would
    you want to post it here?
