Welcome to the Skunkware Java section.

Package List

Acme Labs Java Software

These excellent Java classes were downloaded from Jef Poskanzer's ACME Laboratories. The ACME Labs home page is at http://www.acme.com/ and includes some remarkably useful freeware.

In addition to the Acme class library, i have also downloaded and packaged up a few of Jef's Java applications. These include :

WebCat

fetch URLs and write them to stdout

WebList

make a list of the files in a web subtree

WebCopy

copy a remote web subtree to the local disk

WebGrep

search a web subtree for a pattern

WebPost

post a web query and write the results to stdout

ToPpm

dump out an image URL as PPM

ToGif

dump out an image URL as GIF

Also included is the Java application wrapper script JavaWrapper and a sample shell script i wrote called webget which front-ends the action of WebCat.

The Acme class library gets extracted, by default, into /usr/local/java/Acme. The Java applications get extracted into /usr/local/java and the shell script wrappers get extracted into /usr/local/bin.

The JavaWrapper script checks to see if your CLASSPATH environment variable is set. If not, it sets it to /usr/local/java. If set, it checks to see if /usr/local/java is a component and, if not, appends that.

Many other useful and fun things are at ACME Laboratories.

If you have questions about the packaging of these classess, you may address them to me, Ron Record, via rr@ronrecord.com.

Apache JMeter

The Apache JMeter is a 100% pure Java desktop application designed to test URL behavior and measure their performance.

Apache JMeter may be used to test server performance both on static and dynamic resources (files or CGI, Servlets, Perl scripts). It may well be used to simulate a heavy load on a server or network to test its strength or to analyse overall performance under different load types. You can use it to make a graphical analysis of your server or to test your server/script behavior under heavy concurrent load.

Apache JMeter features include:

• Complete portability and 100% Java purity.
• Full Swing and lightweight component support (precompiled JAR uses packages javax.swing.*).
• Works with any URL supported by the underlying Java platform.
• Allows the use of both GET and POST method with HTTP URLs.
• Full multithreading framework allows concurrent sampling by many threads.
• Several load statistics may be choosen with pluggable timers.
• Data analisys and visualisation plugins allow great extendibility as well as personalization.
• Careful GUI design allows faster operation and more precise timings.

Enhydra - Java application server

Enhydra is an Open Source Java application server run-time and development environment. In development for nearly two years, Enhydra is the basis for a number of Internet applications deployed in mission-critical commercial environments. Its genesis is the direct result of requirements from managers, developers and architects of corporate IT, product companies and Web hosting service providers.

Java application servers are taking Internet application development beyond traditional CGI programming. Requirements for scalable, manageable and maintainable N-tier client/server applications demand the use of application servers. Enhydra and commercial Java application servers offer development tools and common object services capable of supporting rapid development by teams of interface designers and software engineers.

Once compiled, the Enhydra application server serves applications through standard Web servers, such as Apache or Netscape. Enhydra is also capable of handling HTTP requests directly from browsers.

Enhydra's license is based on the FreeBSD-style license. Designed by consultants to balance the need for flexibility and rapid development, its run-time modules and tools include:

• Enhydra Application Framework - Super-servlet run-time environment of common services (session, presentation, database connectivity) for supporting N-tier Enhydra applications.
• Enhydra Multiserver - a servlet running environment with embedded servlet management, monitoring and debugging.
• Enhydra XMLC - XML Compiler (to-be-released), designed to support designer/developer co-development.
• Enhydra Jolt - a structured approach to using embedded Java for dynamic HTML.

Jikes - Java Compiler

Jikes is a freely available Open Source Java compiler from IBM.

Jikes^TM is a research project, providing just the core function of Java compilation. It is not an IBM product, and is certainly not a replacement for, or alternative to, IBM products such as VAJava. The latter is a full, industrial-strength product. Compilation is but one of the many functions that it provides.

Jikes is a source to bytecode compiler, and not a bytecode to native compiler, such as the High Performance Java compiler that is part of the latest VisualAge Product. Jikes is similar to function to the javac compiler shipped with Sun's Java Development Kits (JDK's).

Jikes is designed to operate with any version of the JDK, while other IBM offerings are usually designed to work only with a particular version of the JDK. Thus it is possible that Jikes may reject a program that another IBM-written compiler accepts, or vice versa.

Klassmaster - Java class modifier/obfuscator

Zelix KlassMaster is a utility written in Java TM that reads and modifies Java class (bytecode) files. It is also a Java obfuscator and a Java unobfuscator.

Swing - Java Foundation Classes

The Java Foundation Classes software greatly simplifies the development and deployment of 100% Pure Javatm applications for the Internet, intranet and desktop environments. By using the JFC software, developers can create an application that reflects the operating system on which it runs, or use the GUI components to create their own platform-independent interface. In addition, they can take advantage of a new Java look and feel to be provided by Sun in order to have a uniform look and feel across all platforms.

Description

VRwave is a freely available browser for 3D worlds and scenes modeled in VRML 2.0 (the latest version of the Virtual Reality Modeling Language). It is being developed by the Institute for Information Processing and Computer Supported New Media (IICM) of Graz University of Technology, Austria, the team who brought you the VRweb VRML 1.0 browser. Visit http://www.iicm.edu/ for information about the IICM.

VRwave is the only free VRML browser available in full source code which does not require commercial packages such as Inventor or Motif and which will run on (almost) any Unix or Windows platform. For more information on VRwave, visit http://www.iicm.edu/vrwave . The new name VRwave is intended to distinguish the VRML 2.0 browser written largely in Java from VRweb, which was written in C++. In terms of look and feel, VRwave is a direct successor to VRweb. For more information about VRweb, visit http://skunkware.dev/skunkware/x11/viewers/ .

Productivity

This program displays VRML 2.0 files for the user to manipulate. When used with a web browser, such as Netscape or Mosaic, this 3D viewer allows access to the increasing number of web sites offering virtual reality content and to the advanced HyperWave servers (formerly known as "Hyper-G"). HyperWave servers represent the next generation web solution for publishing rich hypermedia documents in the Internet's World Wide Web and internal TCP/IP networks. For more information about HyperWave, visit http://www.hyperwave.de/.

Work Planned

None

Documentation

Preliminary on-line help for VRwave is included in the archive "Common-VRwave-0.9-Unix.tar.gz". For additional information, view the VRweb User Guide at http://www.iicm.edu/vrweb/help .

Verification

Run "vrwave filename &" (or "$VRWAVE_HOME/vrwave filename &"), where filename is any VRML 2.0 file. If VRweb (the C++ predecessor of VRwave) is executed, it will automatically invoke VRwave when a VRML 2.0 file is encountered. Both VRML 1.0 and VRML 2.0 files have a file suffix of ".wrl".

Known Limitations

Currently, VRwave for Unix is unable to process VRML 1.0 files. For more information, visit http://hiwaay.net/~crispen/vrml/faq.html#q2.

How to get the source

Visit http://skunkware.dev/skunkware/ or ftp://ftp.sco.com/skunkware/src/x11/viewers to obtain a copy of the source in gzip format. To create the executable from the source code (on OpenServer 5.0.4), follow these steps:

• Install the "SVR5 based UnixWare release (codenamed Gemini)" version of the Universal Development Kit (UDK) and Java Development Kit 1.1 (JDK).
• Obtain (or build) and install the UDK version of the Mesa Graphics Library (version 2.4), which is available from SCO SkunkWare. Only the two primary Mesa libraries (libMesaGL.a and libMesaGLU.a) are required.
• Use ksh.
• Ensure that the execution search path includes the directory containing the UDK C/C++ compilers (e.g., "/udk/usr/ccs/bin") BEFORE any other compiler directories (e.g., "/usr/bin/" for the SCO Development System compilers).
• Execute the command: "export CPU=SCO".
• Decompress and untar the archive "vrwave-0.9.tar.gz".
• See file BUILDING for an installation guide.
• The unbuilt source directory hierarchy requires about 3 Meg, and the built hierarchy requires about 5 Meg of disk space. The shared object is under 1 Meg.
• Decompress and untar the archive "Common-VRwave-0.9-Unix.tar.gz".
• Set environment variable VRWAVE_HOME to the directory which was created on unpacking the archive (vrwave-0.9). This directory contains the vrwave wrapper script, help, icons, etc.
