IcedTea-Web è un progetto che:
provides a Free Software web browser plugin running applets written in the Java programming language and an implementation of Java Web Start, originally based on the NetX project.
ma non esiste una build per macOS. Tuttavia, la parte importante di questa applicazione è scritta in Java, quindi possiamo eseguirla direttamente su macOS. Ecco come:
Ottieni la build Debian dalla versione stabile:
wget http://ftp.us.debian.org/debian/pool/main/i/icedtea-web/icedtea-netx-common_1.6.2-3.1_all.deb
Estrai il file deb:
tar xzvf icedtea-netx-common_1.6.2-3.1_all.deb
Estrai l'archivio data.tar.xz che si trova nel file deb:
tar xzvf data.tar.xz
Vai alla directory in cui si trova il file jar principale:
cd usr/share/icedtea-web/
e avvia semplicemente il tuo file jnlp:
java -cp netx.jar net.sourceforge.jnlp.runtime.Boot -Xnofork -jnlp my_application.jnlp
A seconda della tua applicazione potresti dover cambiare le opzioni. Puoi elencarli con:
java -cp netx.jar net.sourceforge.jnlp.runtime.Boot
che risultano in:
SYNOPSIS
javaws [-run-options] jnlp file
javaws [-control-options]
OPTIONS
When specifying options, the name of the jnlp file can be after the command, the -jnlp option, an option with no arguments, or after an argument with an option that takes one argument. A html file that launches a jnlp can be specified after the -html option.
The jnlp-file can either be a url or a local path.
The JNLP file should only be specified once, whether as a main argument, after -jnlp or through an html file.
Control options:
-about - Shows a sample application.(No argument expected)
-help - Prints out information about supported command and basic usage.(No argument expected)
-license - Display the GPL license and exit.(No argument expected)
-viewer - Shows the trusted certificate viewer.(No argument expected)
-Xclearcache - Clean the JNLP application cache.(No argument expected)
Run options:
-allowredirect - Follows HTTP redirects.(No argument expected)
-arg arg - Adds an application argument before launching.(Expected one or more arguments)
-headless - Disables download window, other UIs.(No argument expected)
-html - Location of HTML file to launch (url or file). You can use parameter ALL or numbers (like 1 2 5) to select applets on page. However experimental, this switch should keep you still in safety.(Expected one or more arguments)
-jnlp - Location of JNLP file to launch (url or file).(Exactly one argument expected)
-nosecurity - Disables the secure runtime environment.(No argument expected)
-noupdate - Disables checking for updates.(No argument expected)
-param name=value - Adds an applet parameter before launching.(Expected one or more arguments)
-property name=value - Sets a system property before launching.(Expected one or more arguments)
-strict - Enables strict checking of JNLP file format.(No argument expected)
-update seconds - Check for updates.(Exactly one argument expected)
-verbose - Enable verbose output.(No argument expected)
-version - Print the IcedTea-Web version and exit.(No argument expected)
-Xignoreheaders - Skip jar header verification.(No argument expected)
-xml - Uses a strict XML parser to parse the JNLP file.(No argument expected)
-Xnofork - Do not create another JVM.(No argument expected)
-Xoffline - Prevent ITW network connection. Only cache will be used. Application can still connect.(No argument expected)
-Xtrustnone - Instead of asking user, will foretold all answers as no.(No argument expected)
