B.1 Server Properties
The following table contains a list of properties typically used by servers for configuration. Note that properties are typically restricted from being set from applets.
java.rmi.server.codebase
Indicates the codebase URL of classes originating from the JVM. The codebase property is used to annotate class descriptors of classes originating from a JVM so that the class for an object sent as a parameter or return value in a remote method call can be loaded at the receiver.
java.rmi.server.disableHttp
The implementation of RMI calls through firewalls via proxies has been removed as of JDK 9.
java.rmi.server.hostname
RMI uses IP addresses to indicate the location of a server (embedded in a remote reference). If the use of a hostname is desired, this property is used to specify the fully-qualified hostname for RMI to use for remote objects exported to the local JVM. The property can also be set to an IP address. Not set by default.
java.rmi.dgc.leaseValue
Sets the lease duration that the RMI runtime grants to clients referencing remote objects in the JVM. Defaults to 10 minutes.
java.rmi.server.logCalls
If set to true, server call logging is turned on and
prints to stderr. Defaults to false.
java.rmi.server.useCodebaseOnly
If set to true, when RMI loads classes (if not available
via CLASSPATH) they are only loaded using the URL specified
by the property java.rmi.server.codebase.
java.rmi.server.useLocalHostname
If the java.rmi.server.hostname property is not set and
this property is set, then RMI will not use an IP address to denote the
location (embedded in remote references) of remote objects that are
exported into the JVM. Instead, RMI will use the value of the call to
the method java.net.InetAddress.getLocalHost.
B.2 Activation Properties
The RMI Activation mechanism has been removed from the system.
B.3 Other Properties
These properties are used to locate specific implementation classes within implementation packages. Note: all these properties have been deprecated as of Java 2 SDK, Standard Edition, v1.2.
java.rmi.loader.packagePrefix
Note: this property is deprecated as of Java 2 SDK, Standard Edition, v1.2
The package prefix for the class that implements the interface
java.rmi.server.LoaderHandler. Defaults to
sun.rmi.server.
java.rmi.registry.packagePrefix
Note: this property is deprecated as of Java 2 SDK, Standard Edition, v1.2
The package prefix for the class that implements the interface
java.rmi.registry.RegistryHandler. Defaults to
sun.rmi.registry.
java.rmi.server.packagePrefix
Note: this property is deprecated as of Java 2 SDK, Standard Edition, v1.2
The server package prefix. Assumes that the implementation of the
server reference classes (such as UnicastRef and
UnicastServerRef) are located in the package defined by the
prefix. Defaults to sun.rmi.server.
