The following downloads are available in the distribution:
| Download | Description | Executable? |
|---|
| one-jar-sdk-0.96.jar | The Software Developer Kit, delivered as a self-extracting One-JAR application. Requires Ant for rebuild. Contains source-code for the example application, and everything Ant that you need to start building One-JAR applications. | Yes |
| one-jar-example-0.96.jar | A test-case for various scenarios using One-JAR to load resources, URL's and classes. Contains source code for the examples. | Yes |
| one-jar-dll-0.96.jar | An example of using Windows Native Libraries (DLL's) with One-JAR. Contains C/C++ source code and a mingw make setup. | Yes |
| one-jar-ant-task-0.96.jar | The Ant taskdef code to support a <one-jar> task. Also contains XML definitions for the Ant taskdef, and a macro version of a one-jar builder. Contains source code for the Ant task. | No |
| one-jar-boot-0.96.jar | The low-level JarClassLoader and other One-JAR bootstrap mechanisms Contains source-code for the One-JAR bootstrap classes. | No |
Note: the executable Jar files are command-line tools: do not try to execute them on Windows by double-clicking
the file since you may get unexpected results. Open a DOS command shell and execute them
using the java -jar command.
Which One Do I Need?
- For a quick demo of One-JAR in action, download and run one-jar-example-0.96.jar.
Run using
java -jar one-jar-example.jar
- If you are ready to start developing a One-JAR archive, download and run one-jar-sdk-0.96.jar. This is
a self-extracting archive, so choose carefully where you run it. It contains everything you need to build and test
a simple "Hello One-JAR" example that demonstrates the use of
/main/main.jar and /lib
libraries. You will also need to have access to Ant 1.6.5 or later to build the example.
The SDK can rebuild itself.
- Once you are up-to-speed with One-JAR, the one-jar-ant-task-0.96.jar
contains just the Java class for the
<one-jar> Ant task, as well as a
taskdef. (This file is also delivered with the SDK).
- The minimum set of Java sources and pre-compiled JDK 1.4 classes needed to build a One-JAR archive by hand are contained in
one-jar-boot-0.96.jar.
One-JAR is very compact: the class files have an uncompressed footprint of around 40KB.
