LOG4j allows the developer to control which log statements are output with arbitrary granularity. It is fully configurable at runtime using external configuration files.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
This document provides an overview of logging in Java using Log4j. It discusses why logging is useful, the basic components of Log4j including loggers, appenders, and layouts. It also covers Log4j configuration, optimization best practices, and includes a demonstration of Log4j.

The document contains technical information about network protocols including Ethernet, IP, TCP, frame check sequences, maximum transmission unit, and maximum segment size. It includes diagrams and descriptions of these network concepts. The document is copyrighted by Plugram, Inc. in 2011.
The document discusses a programming project in Java. It includes code for a Main class with a main method that prints "Hello World". There are also hexadecimal strings and copyright notices from the company Plugram, Inc. suggesting it is describing how to set up and run a simple Java program.
The document is a report from an HTML5 API user group meeting in Osaka on October 22, 2011. It discusses HTML5 features like the Canvas API, Form API, local storage and web fonts. The entire document is copyrighted by Plugram Inc. in 2011.
The document discusses Netty, an asynchronous event-driven network application framework for Java. It provides high-performance network programming by leveraging Java NIO and an event-driven architecture. Netty allows building high levels of concurrency with low latency. It includes features like HTTP servers, protocol buffers, and handlers for building custom server-side applications.
This document discusses the T2 framework and thread safety in Java. It provides an overview of the T2 framework, its components like pages, plugins and container adapters. It then discusses thread safety issues in Java like volatile fields and the use of synchronized, Lock and Atomic classes. It analyzes whether the T2 page implementation is thread-safe and provides references for further reading.
GWT meets HTML5 by compiling Java code to optimized JavaScript that can take advantage of HTML5 features like Canvas. GWT uses deferred binding to generate different JavaScript implementations for different browsers to support a wide range of devices from desktop to mobile.
This document discusses Google Web Toolkit (GWT) and HTML5. It provides an agenda for a presentation that includes discussing what GWT is, how it compiles Java code to JavaScript, and its features like deferred binding. It then covers how GWT supports HTML5 features and discusses a session from Google I/O 2010 about GWT and HTML5. Key links are provided about GWT, the I/O session, and using GWT in Eclipse.
The document introduces Slim3 and GWT in Action. It discusses using Slim3, a Java web framework, with Google Web Toolkit (GWT) to create AJAX applications that can take advantage of Slim3 features like hot reloading and validation. It also covers using Slim3 with Google App Engine and its data store and transaction APIs.
