JavaTM RMI Implementation Logging |
Documentation Contents |
As of J2SETM 1.4, Sun's JavaTM Remote Method Invocation (Java RMI) implementation
uses the new Logging APIs to
provide implementation logging output.
The logging configuration file
and programmatic API (java.util.logging)
can be used to configure Java RMI implementation logging.
The java.rmi.server.logCalls system property and the
implementation-specific
sun.rmi.* logging properties that were recognized by
previous J2SE versions still function to set the default levels for
the Java RMI implementation Logger objects and to cause their
output to be directed to System.err as with earlier
versions.
The table below shows the names of the Logger objects
used by the Java RMI implementation and how they correspond to the logging
properties supported by previous versions.
Note that the Java RMI implementation supports a new logging category:
client-side call logging, analagous to the server-side call logging
activated by the java.rmi.server.logCalls property.
Client-side call logging is output to the Logger named
sun.rmi.client.call.
| System Property Name | Logger Name |
Information Logged |
|---|---|---|
java.rmi.server.logCalls
| sun.rmi.server.call
| server-side remote calls and exceptions |
sun.rmi.server.logLevel
| sun.rmi.server.ref
| server-side remote reference activity |
sun.rmi.client.logCalls(new in J2SE 1.4) | sun.rmi.client.call
| client-side remote calls and exceptions |
sun.rmi.client.logLevel
| sun.rmi.client.ref
| client-side remote reference activity |
sun.rmi.dgc.logLevel
| sun.rmi.dgc
| distributed garbage collection activity |
sun.rmi.loader.logLevel
| sun.rmi.loader
| activity of default RMIClassLoader provider
|
sun.rmi.transport.logLevel
| sun.rmi.transport.misc
| transport-layer activity |
sun.rmi.transport.tcp.logLevel
| sun.rmi.transport.tcp
| TCP binding and connection activity |
sun.rmi.transport.proxy.logLevel
| sun.rmi.transport.proxy
| HTTP tunnelling activity |
For both the sun.rmi.client.call and the
sun.rmi.server.call Loggers, exceptions
thrown from remote calls are logged at the level
Level.FINE, and each remote call is logged at the level
Level.FINER. Setting the
java.rmi.server.logCalls or
sun.rmi.client.logCalls system properties to the value
"true" causes the corresponding Logger to be
set to the level Level.FINER.
For the sun.rmi.* logging properties that have names
ending in ".logLevel", a value of "BRIEF"
causes the corresponding Logger to be set to the level
Level.FINE, and a value of "VERBOSE" causes
the corresponding Logger to be set to the level
Level.FINER. Use of the logging configuration file is
now preferred over the use of these sun.rmi.* system
properties for logging.
