11
13 javaws is an implementation of a JNLP client. It uses a JNLP (Java
14 Network Launch Protocol) file to securely run a remote Java application
15 or a Java applet. This implementation of javaws is from the IcedTea
16 project and is based on the NetX project.
17
18 A JNLP file is an xml file that describes how to securely run a remote
19 Java application or a Java applet.
20
21
23 When specifying options, the name of the jnlp file must be the last
24 argument to javaws - all the options must preceede it.
25
26 The jnlp-file can either be a url or a local path.
27
28 Control Options
29
30 By default javaws will launch the jnlp file specified on the command
31 line. The control options can be used to change this behaviour.
32
33 -about Shows a sample application that can be used to test the
34 basic functionality of this implementation.
35
36 -viewer Shows the trusted certificate viewer. This allows a user to
37 list, examine, remove or export trusted certificates. Note
38 that this only reflects the certificates trusted by javaws
39 and not any other certificates or programs.
40
41
42 Run Options
43
44 In the default mode, the following run-options can be used:
45
46 -basedir dir
47 Directory where the cache and certificates to be used are
48 stored.
49
50 -arg arg Adds an application argument before launching.
51
52 -param name=value
53 Adds an applet parameter before launching.
54
55 -property name=value
56 Sets a system property before launching.
57
58 -update seconds
59 Update check if seconds since last checked.
60
61 -license Display the GPL license and exit.
62
63 -verbose Enable verbose output. Very useful in debugging.
64
65 -nosecurity Disables the secure runtime environment.
66
67 -noupdate Disables checking for updates.
68
69 -headless Disables download window, other UIs.
70
71 -strict Enables strict checking of JNLP file format. Any deviations
72 from the JNLP DTD will cause javaws to abort.
73
74 -umask=value
75 Sets the umask for files created by an application.
76
77 -Xnofork Do not create another JVM, even if the JNLP file asks for
78 running in a separate JVM. This is useful for debugging.
79
80 -Jjava-option
81 This passes along java-option to the java binary that is
82 running javaws. For example, to make javaws run with a max
83 heap size of 80m, use -J-Xmx80m.
84
85 -help Print a help message and exit.
86
87
89 ~/.netxrc specifies the location of the base directory
90
91
93 There arent any known bugs. If you come across one, please file it at
94 http://icedtea.classpath.org/bugzilla/
95 Please run javaws in verbose mode and include that output along with
96 the jnlp file when filing out the bug report.
