DriveWire 4 Java by Aaron Wolfe

• DriveWire4 Windows Installer
• Download the Latest release
• DriveWire4 for All Java not included
• DriveWire4 for linux x86_64 with Java included
• DriveWire4 for linux arm_64 with Java included
• DriveWire4 for Windows x64 with Java included

This repo holds two netbeans projects for two versions of DriveWire 4 by Aaron Wolfe that have been slightly modified so that they can be compiled and run with newer versions of java.

• drivewire4_from_source is DriveWire4 version 4.3.3p assembled from the source files available on sourceforge.

Compiling

To compile and run, make sure you have:

• A JDK installed, I used OpenJDK 17 but any other JDK should work as well.
• ant
• NetBeans 16 or higher. For use on ARM64 you'll need to compile a small shared library so you'll need.
• g++
• X11 development headers

With ant installed, navigate to the project directory "drivewire4/drivewire4_from_source" and type the following to compile:

ant

Depending on the version of ant you have this step might produce an error. you'll see something like the following.

BUILD FAILED
/home/rockyhill/Downloads/src/drivewire4/drivewire4_from_source/nbproject/build-impl.xml:1560: /home/rockyhill/Downloads/src/drivewire4/drivewire4_from_source/build/test/classes does not exist.

to solve this all you need to do is create test/classes directory inside of the newly created build directory. on linux you can issue the following command.

mkdir -p build/test/classes

Run the ant command again.

ant

If you are going to run this on a raspberry pi that uses the X11 windowing system, then you'll need a small library that calls XInitThreads(). In order to use SWT, XInitThreads() needs to be called beforehand. For whatver reason, SWT does not take care of this so we must. I found and modified a small library "xdll.cpp" that someone made to solve this issue and it can be found in drivewire4/drivewire4_from_source

Make sure you are compiling this on a raspberry pi and and that you have the X11 develeopment headers and g++ installed. to compile issue the following command. You can also cross compile this for arm64 from your dev computer but I haven't tried that yet.

g++ -o libx.so -shared -fPIC -Wl,-soname,libx.so -L/usr/lib/X11 -I/usr/include/X11 xdll.cpp -lX11

Copy the newly created shared library "libx.so" to "drivewire4/drivewire4_from_source/lib"

Yo can now start DriveWire 4 using the included script for arm64.

./drivewire4_linux_arm_64

For the drivewire4_from_source project use the script for your Operating system after compiling.

• drivewire4_linux_x86_64
• drivewire4_linux_arm_64
• drivewire4_windows_x86_64.bat
• drivewire4_mac_x86_64

For the drivewire4_decompiled version.

java -jar dist/drivewire_decompiled.jar
Error: Unable to initialize main class com.groupunix.drivewireui.MainWin
Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/Layout

• drivewire4_decompiled is a version of the sources obtained from the decompilation of DW4UI.jar.

Watch this video to see how the sourceforge version was modified to compile and run with Java 17.

• Compiling and running DriveWire 4 with OpenJDK 17

Ant uses "nbproject/private/private.properties" to get the path to the JDK from NetBeans. In my case "user.properties.file=/home/rockyhill/snap/netbeans/74/build.properties".
This is quickly solved by either updating that path manually or opening the project in NetBeans and building once. This is a minor annoyance but it's solvable.
After running it, you'll notice that the UI is very differnt from the UI that one sees when running the latest version of DriveWire 4. I suspect this might be a version isssue so hopefully someone will have the source for that and one day this repo can be updated. See screenshots of the UI below.
