SYNOPSIS

options

This represent the command-line options for thermic compiler. See Options for the rmic Compiler.

package-qualified-class-names

Class names that include their packages, for example, java.awt.Color.

DESCRIPTION

The rmic compiler generates stub and skeleton class files using the JRMP.

Note:

The rmic compiler has been updated to remove the -idl and -iiop options and can no longer generate IDL or IIOP stubs and tie classes.

JRMP class files are generated from compiled Java programming language classes that are remote object implementation classes. A remote implementation class is a class that implements the interface java.rmi.Remote. The class names in the rmic command must be for classes that were compiled successfully with the javac command and must be fully package qualified. For example, running the rmic command on the class file name HelloImpl as shown here creates the HelloImpl_Stub.class file in the hello subdirectory (named for the class's package):

A skeleton for a remote object is a JRMP protocol server-side entity that has a method that dispatches calls to the remote object implementation.

A stub is a client-side proxy for a remote object that's responsible for communicating method invocations on remote objects to the server where the actual remote object implementation resides. A client's reference to a remote object, therefore, is actually a reference to a local stub.

By default, the rmic command generates stub classes that use the 1.2 JRMP stub protocol version only, as though the -v1.2 option were specified. See Options for the rmic Compiler.

A stub implements only the remote interfaces, and not local interfaces that the remote object also implements. Because a JRMP stub implements the same set of remote interfaces as the remote object, a client can use the Java programming language built-in operators for casting and type checking.

Note:

The rmic compiler does not support reading of class files that have been compiled with the --enable-preview option, nor does it support generation of stub or skeleton classes that have preview features enabled.

OPTIONS FOR THE RMIC COMPILER

-bootclasspath path

Overrides the location of bootstrap class files.

-classpath path

Specifies the path the rmic command uses to look up classes. This option overrides the default or the CLASSPATH environment variable when it is set. Directories are separated by colons or semicolons, depending on your operating system. The following is the general format for path:

-d directory

Specifies the root destination directory for the generated class hierarchy. You can use this option to specify a destination directory for the stub, skeleton, and tie files.

-g

Enables the generation of all debugging information, including local variables. By default, only line number information is generated.

-Jargument

Used with any Java command, the -J option passes the argument that follows it (no spaces between the -J and the argument) to the Java interpreter.

-keep or -keepgenerated

Retains the generated .java source files for the stub, skeleton, and tie classes and writes them to the same directory as the.class files.

-nowarn

Turns off warnings. When the -nowarn options is used, the compiler doesn't print warnings.

-nowrite

Doesn't write compiled classes to the file system.

-vcompat (deprecated)

Generates stub and skeleton classes that are compatible with both the 1.1 and 1.2 JRMP stub protocol versions. This option was the default in releases before 5.0. The generated stub classes use the 1.1 stub protocol version when loaded in a JDK 1.1 virtual machine and use the 1.2 stub protocol version when loaded into a 1.2 (or later) virtual machine. The generated skeleton classes support both 1.1 and 1.2 stub protocol versions. The generated classes are relatively large to support both modes of operation.

-verbose

Causes the compiler and linker to print messages about what classes are being compiled and what class files are being loaded.

-v1.1 (deprecated)

Generates stub and skeleton classes for the 1.1 JRMP stub protocol version only. The -v1.1 option is useful only for generating stub classes that are serialization-compatible with existing, statically deployed stub classes generated by the rmic command from JDK 1.1 that can't be upgraded (and dynamic class loading isn't being used).

-v1.2 (deprecated)

(Default) Generates stub classes for the 1.2 JRMP stub protocol version only. No skeleton classes are generated because skeleton classes aren't used with the 1.2 stub protocol version. The generated stub classes don't work when they're loaded into a JDK 1.1 virtual machine.

ENVIRONMENT VARIABLES

CLASSPATH

Used to provide the system a path to user-defined classes.
