What's New in This Release:
· Wholly revised the implementation of the logging subsystem, which is no longer based on log4j, but rather on the "logback" libraries.
This has consequences:
· on the libraries to be deployed in the "lib" folder;
· on the launch scripts, which have to point to the new libraries;
· on the configuration file, where the new mandatory element is needed;
· on the logging configuration file, which has to be in the logback format.
· Converting an existing configuration file so that the same log is generated by the new Server implies several steps; you can see the comments in the new Server log configuration file and compare the new file with the old one for hints.
Possible steps are:
· converting the log4j syntax into the logback syntax; note, for instance, that file appender properties are now defined through filters and that the pattern for dates may need quotes; unfortunately, we cannot point you to a complete guide;
· changing the class names of the custom appenders provided by...
