Just Like Us: Digital Debates on Feminism and Fame
by Caitlin E. LawsonIn Just Like Us: Digital Debates on Feminism and Fame, Caitlin E. Lawson examines the rise of celebrity feminism, its intersections with digital culture, and its complicated relationships with race, sexuality, capitalism, and misogyny. Through in-depth analyses of debates across social media and news platforms, Lawson maps the processes by which celebrity culture, digital platforms, and feminism transform one another. As she analyzes celebrity-centered stories ranging from “The Fappening” and the digital attack on actress Leslie Jones to stars’ activism in response to #MeToo, Lawson demonstrates how celebrity culture functions as a hypervisible space in which networked publics confront white feminism, assert the value of productive anger in feminist politics, and seek remedies for women’s vulnerabilities in digital spaces and beyond. Just Like Us asserts that, together, celebrity culture and digital platforms form a crucial discursive arena where postfeminist logics are unsettled, opening up more public, collective modes of holding individuals and groups accountable for their actions.

Just Spring: A Lightweight Introduction to the Spring Framework (Oreilly And Associate Ser.)
by Madhusudhan KondaGet a concise introduction to Spring, the increasingly popular open source framework for building lightweight enterprise applications on the Java platform. This example-driven book for Java developers delves into the framework's basic features, as well as advanced concepts such as containers. You'll learn how Spring makes Java Messaging Service easier to work with, and how its support for Hibernate helps you work with data persistence and retrieval. Throughout Just Spring, you'll get your hands deep into sample code, beginning with a problem that illustrates dependency injection, Spring's core principle. In the chapters that follow, author Madhusudhan Konda walks you through features that underlie the solution. Learn dependency injection through a simple object coupling problem, along with different injection types Tackle the framework's core fundamentals, including beans and bean factories Dive into containers and other advanced concepts, such as event handling and autowiring beans Discover how Spring makes the Java Messaging Service API easier to use Learn how Spring has revolutionized data access with Java DataBase Connectivity (JDBC) Use Spring with the Hibernate framework to manipulate data as objects
Just Spring Data Access
by Madhusudhan KondaJDBC has simplified database access in Java applications, but a few nagging wrinkles remain--namely, persisting Java objects to relational databases. With this book, you'll learn how the Spring Framework makes that job incredibly easy with dependency injection, template classes, and object-relational-mapping (ORM). Through sample code, you'll discover how Spring streamlines the use of JDBC and ORM tools such as Hibernate, the Java Persistence API (JPA), and Java Data Objects (JDO). If you're a Java developer familiar with Spring (perhaps through O'Reilly's Just Spring tutorial) and want to advance your data access skills, this book shows you how. Learn how to use Spring's basic and advanced data access tools Work with Spring's JdbcTemplate class to separate non-critical code from business code Eliminate placeholder variables in your queries with the NamedParameterJdbcTemplate class Use Spring's template classes to perform batch executions Operate inserts on database tables without writing any SQL statements Learn about Spring's support for Hibernate as an object-relational-mapping tool Use JPA as a standards-based ORM--alone or with Spring support Move data from a relational to a non-relational database with JDO
Just Spring Integration
by Madhusudhan KondaGet started with Spring Integration, the lightweight Java-based framework that makes designing and developing message-oriented architectures a breeze. Through numerous examples, you'll learn how to use this open source framework's basic building blocks to work with both inter- and intra-application programming models. If you're a Java developer familiar with the Spring framework (perhaps through O'Reilly's Just Spring tutorial) and want to advance your skills with Enterprise Application Integration (EAI) patterns, and messaging systems in particular, this book is ideal. Learn Spring Integration fundamentals, including channels, endpoints, and messages Use message channels to decouple applications, separating producers from consumers Discover how common endpoint patterns separate a messaging application's business logic from integration details Create a seamless integration between the endpoints, using Transformers Implement Spring Integration's flow components to design your messaging application's business flow Configure the framework's File, FTP, JMS, and JDBC adapters to integrate with external systems

Jython Essentials
by Samuele Pedroni Noel RappinJython is an implementation of the Python programming language written in 100% pure Java, so it runs under any compliant Java Virtual Machine. The secret to Jython's popularity lies in the combination of Java's libraries and tools with Python's rapid development capabilities. With Jython, you can write Python programs that integrate seamlessly with any Java code. And like Python, Jython can be used interactively, so you can get immediate results as you are programming. Jython Essentials provides a solid introduction to the Python language, offering a brief but thorough tour of the Python concepts you'll need to understand to use Jython effectively. The book makes frequent comparisons between Python and Java, with special emphasis on the different object-oriented semantics of the two languages, so Java programmers can quickly get up to speed with Jython. Jython Essentials also covers the various ways in which Jython and Java can interact. For example, Jython code can create instances of pre-existing Java classes and call methods in those instances. You can write Jython classes that are direct subclasses of existing Java classes and use introspection to discern the capabilities of JavaBeans components. This book provides examples of using Jython with existing Java libraries, including the Swing GUI toolkit, the JDBC database API, the Servlet API, and various XML tools. And finally, the book shows how Jython can be used as a scripting language within a Java program. With Jython Essentials, you have everything you need to start creating applications that mix the best of Python's interactivity and Java's robust libraries.
