1 Introduction
The JAR files (Java ARchive) allow to archive files in a JAVA specific format which is indeed portable.
The JAR files are in fact just some ZIP files renamed (we can unzip them).
The advantage of JAR archives is that tey can be run like .exe files under WINDOWS.
2 Build from scratch
- File MANIFEST.MF:
Main-Class: ClassePrincipale Class-Path: \Archives\liquidlnf.jar // Le fichier JAR contenant le Look \& Feel Liquid
- Command:
$ jar cvmf MANIFEST.MF Programme.jar *.class $ unzip Programme.jar
3 Netbeans
3.1 Including libraries
If we enable the WEBSTART option, the .jar libraries files will load even if they are not included into the project JAR file.
To do it, you must right click on the project node and choose ``proporties'' and then ``web start''.
3.2 Including ressources
In order to include the etc/ directory (and the nectar.xml configaration file) into the sources.
To do it, we have to right click on the project node and choose ``proporties'' and then ``sources'' an add the etc/ directory
as a ``source package folder''.
Note that the nectar.xml is not prefixed by the project name nor by etc/.
try {
// use the user configuration file (local copy)
doc = builder.build(new FileInputStream("etc/" + Main.confFile));
UI_Log.logger.info("LOCAL configuration file loaded");
} catch (Exception f) {
UI_Log.logger.info("Cannot load local configuration file... try to look into the JAR");
// use the default configuration file (into the jar)
ClassLoader cl = Thread.currentThread().getContextClassLoader();
InputStream jarFile = cl.getResourceAsStream("nectar.xml");
if (jarFile == null) {
UI_Log.logger.severe("Cannot load default configuration from JAR file");
return;
}
else {
UI_Log.logger.info("DEFAULT configuration file loaded");
doc = builder.build(jarFile);
}
}
