Java Remote Method Invocation

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.

Property
Description

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

If set to true, disables the use of HTTP for RMI calls. This means that RMI will never resort to using HTTP to invoke a call via a firewall. Defaults to false (HTTP usage is enabled).

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.

Property	Description
`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`	If set to `true`, disables the use of HTTP for RMI calls. This means that RMI will never resort to using HTTP to invoke a call via a firewall. Defaults to `false` (HTTP usage is enabled).
`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`.
