P4Java, from Perforce Software, is a pure Java API for accessing Perforce SCM services from within Java applications, servlets, plug-ins, and other Java contexts. P4Java enables developers to tightly integrate Perforce functionality into tools such as CruiseControl, Maven, and Ant, and in environments such as J2EE-based web application and web service frameworks. Perforce SCM versions and manages source code and digital assets for enterprises large and small.
P4Java is a pure Java implementation of the client-side Perforce networking protocol that speaks directly to the Perforce server. Perforce-managed resources, files, and services are available as first-class Java interfaces, classes, methods, and objects, rather than simple strings or command-line-like functions. The new P4Java API allows Java plug-in and apps developers direct access to Perforce SCM features and services in Java-natural ways.
The Perforce Java API is available now, at no additional charge, with the latest release of the Perforce Server, and is supported on servers starting from version 2007.3. Perforce pricing is all-inclusive; there are no add-on components that require licensing. End-user licenses for the complete solution, including one year of support and maintenance, start at $900 per seat; volume discounts are available.
