Add JavaFX to Web Pages with Applets - JavaFX: Developing Rich Internet Applications - page 243

<offline-allowed> is not specified, the application can only be run when the
system is connected back to the applet's source location.

<security>
The <security> element defines the security permissions the applet is allowed
to have. Each applet, by default, is run in a security-restricted environment. If
<all-permissions> is defined, the applet will have full access to the user's
machine. In this case, the JAR files must be digitally signed and the user is asked
whether to grant this permission prior to the applet running.

<resources>
The <resources> element identifies the resources needed for running the applet.
This includes specifying which versions of Java are required to run the applet.
This section also identifies all the archive files needed by the applet.

<applet-desc>
The <applet-desc> element defines the properties for the applet. There is some
overlap with these settings and the settings set from the HTML page using the
JavaScript code defined in the next section. The overlap is resolved as defined in
Table 9.1.

Ta b l e 9 . 1 Precedence Rules for <applet> HTML Tag and JNLP Settings

Property Precedence

width HTML

height HTML

codebase JNLP (If absolute)

code* JNLP

archive* JNLP

java_arguments* JNLP

java_version* JNLP

* When using JNLP applets, applet properties code , archive , java_arguments , and java_

version are unnecessary as these are defined in the JNLP file. Applet parameters are
merged with the settings defined in the JNLP file. If the same parameters are specified in
both, the applet's settings take precedence except for java_arguments and
java_version .
