Back Forward JAR

Java 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.

PRPC 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 PRPC. See the PDN article About the Process Commander class paths.

For a list and description of the JAR files included with PRPC, including those of third parties redistributed, see the PDN article JAR files distributed with V5.1.
