Install log formatter in glassfish

Question

I don´t like the output of the com.sun.enterprise.server.logging.UniformLogFormatter which might be uniform but not very helpful. So in a first step I just replaced it with the java.util.logging.SimpleFormatter. This actually works fine but for a java.lang.ClassCastException exception:

java.lang.ClassCastException: java.util.logging.SimpleFormatter cannot be cast to com.sun.enterprise.server.logging.UniformLogFormatter

Being a perfectionist I want to get rid of this exception and I wonder if I can create my own child class from com.sun.enterprise.server.logging.UniformLogFormatter and somehow install this class into glassfish.

How to install a custom log formatter into Glassfish?

Extending the logger from java.util.logging.SimpleFormatter is no longer a problem, but required (at least on GlassFish 3.1.2). See this #9609880 for a complete example. – Keeler

Have a look at Configuring format of server log on the GlassFish forums. Basically, you need to:

• Implement your formatter
• Put the jar with your formatter in domain_dir/lib/ext.
• Declare it in <mydomain>/config/logging.properties

I finally found time to create the needed loggers. However they leave a little after-taste as I needed auto-depends.jar and logging.jar to compile and run as well as common-util.jar to run. All from glassfish/modules.That opens two rhetoric question: 1) How much memory did I just waste for a simple logger. 2) Who was the idiot who implemented com.sun.enterprise.server.logging.UniformLogFormatter as a class instead of an interface. – Khz
