Hi, I´m an habitual user of log4j and I´m trying to port my application to logback. The first impression of this new tool was very good; the pluggin for Eclipse IDE has a good apparience. But I´m experiencing a little worrisomely problem: some logging lines cause the Eclipse plugin stops to write the rest of logging lines. If I activate a ConsoleAppender, I can view the rest of the logging lines at the standard console, but the Eclipse plugins don´t show that lines. The line causing the Eclipse plugin stops to work is: Method[] methods = clazz.getDeclaredMethods(); log.debug("method: {}", methods[i]); I´ve seen an error on the Error Log eclipse´s view saying that java.lang.reflect.Method is not Serializable, and the plugin do not show the rest of the logging lines. I´ve experimented similar error when I try to log a message line that contains an own object such as a bean. In this case, the error is a ClassNotFoundException because of the logback eclipse plugin can´t find the bean class. The bean class is in my proyect classpath and in the application server, logback goes fine because it can reach the bean class. How can I make accesible my classes to the logback plugin. Could be these two bugs of the plugin? If you need it, I can post the stacktrace of the error that appears at Eclipse Error Log View. Thanks a lot. P.D.: I´ve sent this message to the logback user´s list, but later I´ve thought the most appropiate list for this problem should be the dev list.
