JAR (Java ARchive) is a file format based
on the popular ZIP file format. A JAR file aggregates many
files into one. Although JAR can be used as a general archiving
tool, its primary use is to allow Java applets and their
requisite components (.class files, images, and other binary
elements) to be downloaded to a browser in a single HTTP
transaction, rather than opening a new connection for each
piece.
The JAR format also supports compression, which reduces the size of the file and improves download time. Entries in a JAR file may be digitally signed by the author to authenticate their origin.
Process Commander can access external JAR files through several means including Connect Java rules.
From the System Management application, use the
Advanced > Class Loader menu item to reload
(refresh) the JAR files available to Process Commander. See the
Pega Developer Network article PRKB-20931 About the Process Commander class
paths.
For a list and description of the JAR files included with
Process Commander, including those of third parties
redistributed, see the Pega Developer Network article
PRKB-21570 JAR files distributed with
V5.1.
