Perfect! That works out very well.

There are a couple ways:
1) Use StatusPrinter.printInCaseOfErrorsOrWarnings(loggerContext)

2) Load hard-coded string of configuration XML w/configuration.debug set to 'true':
	static final String LOGBACK_XML = 

		"<configuration debug='true'>" + 		"  <appender name='FILE' class='ch.qos.logback.core.RollingFileAppender'>" +

		"    <file>foo.log</file>" +		"    <append>true</append>" +

		"    <encoder>" +		"      <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>" +

		"    </encoder>" +		"  </appender>" +		"  <root level='INFO'>" +

		"    <appender-ref ref='FILE' />" +		"  </root>" +

		"</configuration>"		;	

	static public void configLogback() {		LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();

                try {               JoranConfigurator configurator = new JoranConfigurator();               configurator.setContext(lc);               lc.reset();            

               configurator.doConfigure(new ByteArrayInputStream(LOGBACK_XML.getBytes()));           } catch (JoranException je) {               je.printStackTrace();

           // you can also print the errors/warning explicitly (instead of debug='true' in xml)           //StatusPrinter.printInCaseOfErrorsOrWarnings(lc);

I ended up accessing BasicStatusManager directly to get the message out so I can at least see what's going on. Then I was able to figure out that some required configuration wasn't set for RollingPolicy object.

Please let me know if there is a way to make BasicStatusManager cough up all log messages for LogBack. Otherwise, I guess I just have to do it the way I'm doing now when things are not working.
