P4Java is officially supported by Perforce. Pull requests will be managed by Perforce's engineering teams. We will do our best to acknowledge these in a timely manner based on available capacity. Issues will not be managed on GitHub. All issues should be recorded via Perforce's standard support process (https://www.perforce.com/support/request-support).
P4Java is a Java-native API for accessing Perforce SCM services from within Java applications, servlets, plugins, and other Java contexts.
- Perforce server at Release 2015.1 or higher.
- Java: full standard JDK 17 or later.
- SSL: unlimited strength JCE (Java Cryptography Extension) package for 256-bit encryption level SSL connection to a secure Perforce server.
Perforce server 2015.1 or higher supports 256-bit SSL connections and trust establishment via accepting the fingerprint of the SSL certificate's public key. The standard JDK comes with 128-bit encryption level ciphers. In order to use P4Java to connect to a secure Perforce server, you must download and install the unlimited strength JCE package for your JDK version.
To make a secure connection using P4Java, simply append 'ssl' to the end of the P4Java protocol (i.e. 'p4javassl://perforce:1667'). For new a connection or a key change, you must also (re)establish trust using the IOptionsServer's 'addTrust' method. See example code snippet below:
// Create a P4Java SSL connection to a secure Perforce server
try {
String serverUri = "p4javassl://perforce:1667";
Properties props = null;
IOptionsServer server = ServerFactory.getOptionsServer(serverUri, props);
// assume a new first time connection
// you should also handle a key change situation...
server.addTrust(new TrustOptions().setAutoAccept(true));
// if all goes well...
IServerInfo serverInfo = server.getServerInfo();
} catch (P4JavaException e) {
// process P4Java exception
} catch (Exception e) {
// process other exception
}
P4Java 2020.1 has changed the default TLS support to TLSv1.2 for use with Perforce server 2019.1 or greater this can be modified using the JVM option:
java -DsecureSocketEnabledProtocols=TLSv1.2
