jar
Subelement
The
jar
element specifies a JAR file to be loaded by the JNLP Client through its
ClassLoader
.
Attributes allowed for this element are as follows:
•
version
: An optional attribute that uniquely identifies (together with the
href
attribute)
the JAR file. See the versioning section for details.
•

server. This is a required attribute.
•
size
: An optional attribute that specifies the size of the JAR file, measured in bytes.
•
download
: Specifies when it must be loaded by the JNLP Client. It has two possible val-
ues:
eager
or
lazy
.
•
part
: An optional attribute for grouping together resources. Parts are local to the JNLP
file. Specifications of this attribute also influence the downloading. All resources with the
same
part
attribute are downloaded together.
•
main
:The JAR that contains the class to be launched through its
main(..)
method. Only
one
main
attribute can be used for a JNLP file. If no
main
attribute is specified, the first
jar
element encountered in the JNLP file is used as the main JAR.
