4.6. Logging

The platform uses Logback framework for logging.

To output to the log, use SLF4J API: get a logger for the current class and invoke one of its methods, for example:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Foo {
    // create logger
    private Logger log = LoggerFactory.getLogger(Foo.class);

    private void someMethod() {
        // output message with DEBUG level
        log.debug("someMethod invoked");

Logs for the Middleware, Web Client and Web Portal blocks are configured at the application server level; in fast deployment mode the server is Tomcat.
