10 javaws [-control-options]
11
13 javaws is an implementation of a JNLP client. It uses a JNLP (Java Net‐
14 work Launch Protocol) file to securely run a remote Java application or
15 a Java applet. This implementation of javaws is from the IcedTea
16 project and is based on the NetX project.
17 A JNLP file is an xml file that describes how to securely run a remote
19 Java application or a Java applet.
20
23 When specifying options, the name of the jnlp file can be after the
24 command, the -jnlp option, an option with no arguments, or after an
25 argument with an option that takes one argument. A html file that
26 launches a jnlp can be specified after the -html option.
27 The jnlp-file can either be a url or a local path.
28 The JNLP file should only be specified once, whether as a main argu‐
29 ment, after -jnlp or through an html file.
30 Control options:
32 -about Shows a sample application.(No argument expected)
35 -help Prints out information about supported command and basic
37 usage.(No argument expected)
38 -license Display the GPL license and exit.(No argument expected)
40 -viewer Shows the trusted certificate viewer.(No argument expected)
42 -Xclearcache
44 Clean the JNLP application cache.(No argument expected)
45 Run options:
48 -allowredirect

60 -html Location of HTML file to launch (url or file). You can use
62 parameter ALL or numbers (like 1 2 5) to select applets on
63 page. However experimental, this switch should keep you
64 still in safety.(Expected one or more arguments)
65 -jnlp Location of JNLP file to launch (url or file).(Exactly one
67 argument expected)
68 -nosecurity Disables the secure runtime environment. You need also

84 expected)
85 -update seconds
87 Check for updates.(Exactly one argument expected)
88 -verbose Enable verbose output.(No argument expected)
90 -version Print the IcedTea-Web version and exit.(No argument
92 expected)
93 -Xignoreheaders

96 -xml Uses a strict XML parser to parse the JNLP file.(No argu‐
98 ment expected)

106 argument expected)
