JDUN - Usage Instructions

JDUN Documentation

JDUN supports Windows 98, Me, NT4, 2000, XP, and Vista
Non-windows operating systems are not supported
JDUN requires the inclusion of native DLL files with your java application. These files must be located in either the current working directory or on the system path of the machine.

To add the JDUN classes to your project, simply add the included jar file to your classpath. Some IDEs refer to this as libraries on the Java build path of your project. You can then build your project and include the JDUN classes with your application distributables.

There are numerous free java obfuscators available. We recommend ProGuard. For JDUN to work, some classes and methods must not be obfuscated. Below is an example of a proguard obfuscation file you could use with JDUN.

-libraryjars <java.home>\lib\rt.jar
-injars      myapp_pre.jar
-outjar      myapp.jar

# keep all native method names and the names of their classes
-keepclasseswithmembernames class * {
    native <methods>;
}

# keep class names DialUpManager, DialUpDevice, and DialUpEntryProperties
-keepnames class com.jpackages.jdun.DialUpManager
-keepnames class com.jpackages.jdun.DialUpDevice
-keepnames class com.jpackages.jdun.DialUpEntryProperties

# keep method notifyCallback
-keep class com.jpackages.jdun.DialUpManager {
  private void notifyCallback(java.lang.String, int, int);
}

# keep all DialUpEntryProperties methods
-keep class com.jpackages.jdun.DialUpEntryProperties {
  <methods>;
}
