Java^TM 2 SDK
Tools and Utilities

Each of the development tools comes in a Microsoft Windows version (Windows) and a Solaris or Linux version. There is virtually no difference in features between versions. However, there are minor differences in configuration and usage to accommodate the special requirements of each operating system. (For example, the way you specify directory separators depends on the OS.)

The following documents contain important information you will need to know to get the most out of the SDK tools.

Tool Changes in Java 2 SDK, v1.4
[Solaris, Linux and Windows]

The sections below provide a brief introduction to the tools in the Java 2 SDK, with links to their reference pages:

Basic Tools (javac, java, javadoc, appletviewer, jar, jdb, javah, javap, extcheck)
Remote Method Invocation (RMI) Tools (rmic, rmiregistry, rmid, serialver)
Internationalization Tools (native2ascii)
Security Tools (keytool, jarsigner, policytool, kinit, klist, ktab)
Java IDL and RMI-IIOP Tools (tnameserv, idlj, orbd, servertool)
Java Plug-in^TM Tools

Basic Tools

These tools are the foundation of the Java 2 SDK. They are the tools you use to create and build applications.

Java IDL and RMI-IIOP Tools

These tools are used when creating applications that use OMG-standard IDL and CORBA/IIOP.

Tool Name with
Reference Links Brief Description

tnameserv Provides access to the naming service.

idlj Generates .java files that map an OMG IDL interface and enable an application written in the Java programming language to use CORBA functionality.

orbd Provides support for clients to transparently locate and invoke persistent objects on servers in the CORBA environment. ORBD is used instead of the Transient Naming Service, tnameserv. ORBD includes both a Transient Naming Service and a Persistent Naming Service. The orbd tool incorporates the functionality of a Server Manager, an Interoperable Naming Service, and a Bootstrap Name Server. When used in conjunction with the servertool, the Server Manager locates, registers, and activates a server when a client wants to access the server.

servertool Provides ease-of-use interface for the application programmers to register, unregister, startup, and shutdown a server.
