  • Configuring & Using Apache Tomcat 4 a Tutorial on Installing and Using
    Configuring & Using Apache Tomcat 4 A Tutorial on Installing and Using Tomcat for Servlet and JSP Development Taken from Using-Tomcat-4 found on http://courses.coreservlets.com Following is a summary of installing and configuring Apache Tomcat 4 for use as a standalone Web server that supports servlets 2.3 and JSP 1.2. Integrating Tomcat as a plugin within the regular Apache server or a commercial Web server is more complicated (for details, see http://jakarta.apache.org/tomcat/tomcat-4.0-doc/). Integrating Tomcat with a regular Web server is valuable for a deployment scenario, but my goal here is to show how to use Tomcat as a development server on your desktop. Regardless of what deployment server you use, you'll want a standalone server on your desktop to use for development. (Note: Tomcat is sometimes referred to as Jakarta Tomcat since the Apache Java effort is known as "The Jakarta Project"). The examples here assume you are using Windows, but they can be easily adapted for Solaris, Linux, and other versions of Unix. I've gotten reports of successful use on MacOS X, but don't know the setup details. Except when I refer to specific Windows paths (e.g., C:\blah\blah), I use URL-style forward slashes for path separators (e.g., install_dir/webapps/ROOT). Adapt as necessary. The information here is adapted from More Servlets and JavaServer Pages from Sun Microsystems Press. For the book table of contents, index, source code, etc., please see http://www.moreservlets.com/.

  • Solutions to Exercises
    533 Appendix Solutions to Exercises Chapters 1 through 10 close with an “Exercises” section that tests your understanding of the chapter’s material through various exercises. Solutions to these exercises are presented in this appendix. Chapter 1: Getting Started with Java 1. Java is a language and a platform. The language is partly patterned after the C and C++ languages to shorten the learning curve for C/C++ developers. The platform consists of a virtual machine and associated execution environment. 2. A virtual machine is a software-based processor that presents its own instruction set. 3. The purpose of the Java compiler is to translate source code into instructions (and associated data) that are executed by the virtual machine. 4. The answer is true: a classfile’s instructions are commonly referred to as bytecode. 5. When the virtual machine’s interpreter learns that a sequence of bytecode instructions is being executed repeatedly, it informs the virtual machine’s Just In Time (JIT) compiler to compile these instructions into native code. 6. The Java platform promotes portability by providing an abstraction over the underlying platform. As a result, the same bytecode runs unchanged on Windows-based, Linux-based, Mac OS X–based, and other platforms. 7. The Java platform promotes security by providing a secure environment in which code executes. It accomplishes this task in part by using a bytecode verifier to make sure that the classfile’s bytecode is valid. 8. The answer is false: Java SE is the platform for developing applications and applets. 533 534 APPENDIX: Solutions to Exercises 9.

  • Fedora Core, Java™ and You
    Fedora Core, Java™ and You Gary Benson Software Engineer What is Java? The word ªJavaº is used to describe three things: The Java programming language The Java virtual machine The Java platform To support Java applications Fedora needs all three. What Fedora uses: GCJ and ECJ GCJ is the core of Fedora©s Java support: GCJ includes gcj, a compiler for the Java programming language. GCJ also has a runtime and class library, collectively called libgcj. The class library is separately known as GNU Classpath. ECJ is the Eclipse Compiler for Java: GCJ©s compiler gcj is not used for ªtraditionalº Java compilation. More on that later... Why libgcj? There are many free Java Virtual machines: Cacao, IKVM, JamVM, Jikes RVM, Kaffe, libgcj, Sable VM, ... There are two main reasons Fedora uses libgcj: Availability on many platforms. Ability to use precompiled native code. GNU Classpath Free core class library for Java virtual machines and compilers. The JPackage Project A collection of some 1,600 Java software packages for Linux: Distribution-agnostic RPM packages. Both runtimes/development kits and applications. Segregation between free and non-free packages. All free packages built entirely from source. Multiple runtimes/development kits may be installed. Fedora includes: JPackage-compatible runtime and development kit packages. A whole bunch of applications. JPackage JOnAS Fedora©s Java Compilers gcj can operate in several modes: Java source (.java) to Java bytecode (.class) Java source (.java) to native machine code (.o) Java bytecode (.class, .jar) to native machine code (.o) In Fedora: ECJ compiles Java source to bytecode. gcj compiles that bytecode to native machine code.

  • Towards Architectural Programming of Embedded Systems
    Towards Architectural Programming of Embedded Systems Arne Haber, Jan O. Ringert, Bernhard Rumpe Software Engineering, RWTH Aachen University, Germany http://www.se-rwth.de/ Abstract: Integrating architectural elements with a modern programming language is essential to ensure a smooth combination of architectural design and programming. In this position statement, we motivate a combination of architectural description for distributed, asynchronously communicating systems and Java as an example for such an integration. The result is an ordinary programming language, that exhibits archi- tecture, data structure and behavior within one view. Mappings or tracing between different views is unnecessary. A prototypical implementation of a compiler demon- strates the possibilities and challenges of architectural programming. 1 Java with Architectural Elements As stated in [MT00] there are a number of languages that support design, analysis, and further development of software-system-architectures. These languages are commonly known as Architecture Description Languages (ADL) and allow a high level description of software systems of a specific domain. Using an ADL enables reasoning about specific system properties in an early development stage [GMW97]. Furthermore, there are quite often mappings from architecture to a General Purpose Language (GPL), producing code frames for the GPL. This helps ensuring the architectural consistency initially, but when the code evolves the architecture becomes implicitly polluted or when the architecture shall be evolved this needs to be done on the code level. Tracing is therefore important to keep architecture and code aligned. However, it would be much better to integrate both, architecture and code into one single artifact such that tracing is not necessary anymore.

  • Intro to Java
    Introduction to Java 1 / 10 Java I Developed for home appliances - cross-platform VM a key feature I Originally called Oak I Gained notariety with HotJava web browser that could run “programs over the internet” called applets I Gained popularity when Netscape included Java VM in Navigator web browser I JavaScript is purely a marketing label meant to capitalize on Java hype - there is no relationship between Java and JavaScript I Java is a general-purpose application programming language. I Java applets are now very rare. The bulk of Java code runs on (web) servers. 2 / 10 The Java Programming Language I Java is part of the C family. Same syntax for variable declarations, control structures I Java came at a time when C++ was king. C++ was a notoriously complex object-oriented extension to C. I Java improved on several key aspects of C++, greatly simplifying software development I Two most compelling features of Java were cross-platform deployablility (“write once, run anwhere”) and autoatic garbage collection I These two advantages, especially garbage collection, drove Java adoption 3 / 10 The Java Platform Three components of the Java platform: I The Java programming language I The Java Virtual Machine (JVM) I The Java standard library Java is both compiled and interpreted: I Java source files (ending in .java) are compiled to java bytecode files (ending in .class) I Java bytecode is then interpreted (run) by the JVM I Compiling and running can be done on different machines – bytecode is portable (more precisely, the JVM on each platform accepts the same bytecode).

  • Java Programming 24-Hour Trainer, Second Edition
    11 Introducing Java During the last two decades Java has maintained its status as one of the most popular programming languages for everything from programming games to creating mission-critical applications, such as those for trading on Wall Street or controlling Mars rovers. For the current popularity chart see the Tiobe Index at http:// www.tiobe.com/index.php/content/paperinfo/tpci/index.html. In this lesson you are intro‐ duced to some of the very basic Java terms. You also download and install the Java Development Kit (JDK) and compile your first program. WHY LEARN JAVA? The Java programming language was originally created in 1995 by James Gosling from Sun Microsystems (acquired by Oracle Corporation in 2010). The goal was to provide a simpler and platform-independent alter‐ native to C++. Java programs run inside the Java Virtual Machine (JVM), which is the same on every platform from the application programmer’s perspective. You find out what platform independence means a little later, in the section “The Life Cycle of a Java Program”. For now, let’s look at some of the reasons why Java can be your language of choice. Java is a general-purpose programming language that’s used in all industries for almost any type of application. If you master it, your chancesCOPYRIGHTED of getting employed as a software MATERIAL developer will be higher than if you specialize in some domain-specific programming languages. There are more than nine million professional Java developers in the world, and the majority of them are ready to share their knowledge by posting blogs and articles or simply answering technical questions online.

  • 1 Compiling Java Programs
    CS 61B P. N. Hilfinger Basic Compilation: javac, gcc, g++ 1 Compiling Java Programs [The discussion in this section applies to Java 1.2 tools from Sun Microsystems. Tools from other manufac- turers and earlier tools from Sun differ in various details.] Programming languages do not exist in a vacuum; any actual programming done in any language one does within a programming environment that comprises the various programs, libraries, editors, debuggers, and other tools needed to actually convert program text into action. The Scheme environment that you used in CS61A was particularly simple. It provided a component called the reader, which read in Scheme-program text from files or command lines and converted it into internal Scheme data structures. Then a component called the interpreter operated on these translated pro- grams or statements, performing the actions they denoted. You probably weren’t much aware of the reader; it doesn’t amount to much because of Scheme’s very simple syntax. Java’s more complex syntax and its static type structure (as discussed in lecture) require that you be a bit more aware of the reader—or compiler, as it is called in the context of Java and most other “production” programming languages. The Java compiler supplied by Sun Microsystems is a program called javac on our systems. You first prepare programs in files (called source files) using any appropriate text editor (Emacs, for example), giving them names that end in ‘.java’. Next you compile them with the java compiler to create new, translated files, called class files, one for each class, with names ending in ‘.class’.

  • Virtual Machines Due Date: 6/3 Demo Date: 6/4
    INF 212 Analysis of Programming Languages Project 8 – Virtual Machines Due date: 6/3 Demo date: 6/4 Goal: Get acquainted with a virtual machine. Similarly to the type checking homework, the concrete task in this homework is very simple, but it requires you to analyze and understand an existing Java VM implementation. The task is just a means to the end goal, and not the goal in itself. In process of achieving the goal, students with Windows machines will get the extra benefit of getting acquainted with another kind of virtual machine: an entire operating system virtual machine. For this one, you will not be looking inside, you will only install and use it. Students with Macs and Linux will not need this (and hence miss the opportunity to use it...). Description You will be using JamVM, an open source Java virtual machine (http://jamvm.sourceforge.net/). Start by downloading the latest release. In this project you will create new Opcodes for JamVM. Opcodes 248-255 are unused by JamVM and thus are the Opcodes that you will be adding additional functionality for. A testcase is provided for you (here). Since the compiler will not be aware of your new opcodes, you will need to edit your .class files manually using a binary/hex editor if you wish to create different test cases. The new opcodes will replace the IADD opcode during a standard arithmetic expression. For an expression x + y you need to replace the byte representing IADD (60 in hexadecimal) with the value of the new opcode.
