| # JavaTM 2 SDK Tools and Utilities | Documentation Contents

Each of the development tools comes in a Microsoft Windows version (Windows) and a Solaris version. There is virtually no difference in features between Windows and Solaris 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.

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-inTM Tools

Basic Tools
These tools are the foundation of the Java 2 SDK. They are the tools you use to create and build applications.
|  | Reference Pages
javac | The compiler for the Java programming language. | [Solaris and Linux] [Windows]
java | The launcher for Java applications. In this release, a single launcher is used both for development and deployment. The old deployment launcher, jre, is no longer provided. | [Solaris] [Linux] [Windows]
javadoc | API documentation generator. For links to Javadoc enhancements, Doclet API, Taglet API, doclets and more, see the Javadoc Tool Page | [Solaris and Linux] [Windows]
appletviewer | Run and debug applets without a web browser. | [Solaris and Linux] [Windows]
jar | Manage Java Archive (JAR) files. | [Solaris and Linux] [Windows]
jdb | The Java Debugger. | [Solaris and Linux] [Windows]
javah | C header and stub generator. Used to write native methods. | [Solaris and Linux] [Windows]
javap | Class file disassembler | [Solaris and Linux] [Windows]
extcheck | Utility to detect Jar conflicts. | [Solaris and Linux] [Windows]
Remote Method Invocation (RMI) Tools
These tools help to create apps that interact over the Web or other network.
rmic | Generate stubs and skeletons for remote objects. | [Solaris and Linux] [Windows]
rmiregistry | Remote object registry service. | [Solaris and Linux] [Windows]
rmid | RMI activation system daemon. | [Solaris and Linux] [Windows]
serialver | Return class serialVersionUID. | [Solaris and Linux] [Windows]
Internationalization Tools
This tool helps to create localizable apps.
native2ascii | Convert text to Unicode Latin-1. | [Solaris and Linux] [Windows]
Security Tools
These tools help you set security policies on your system and create apps that can work within the scope of security policies set at remote sites.
keytool | Manage keystores and certificates. | [Solaris and Linux] [Windows]
jarsigner | Generate and verify JAR signatures. | [Solaris and Linux] [Windows]
policytool | GUI tool for managing policy files. | [Solaris and Linux] [Windows]
These tools help you obtain, list, and manage Kerberos tickets.
kinit | Tool for obtaining Kerberos v5 tickets. | [Solaris and Linux] [Windows]
klist | Command-line tool to list entries in credential cache and key tab. | [Solaris and Linux] [Windows]
ktab | Command-line tool to help the user manage entires in the key table. | [Solaris and Linux] [Windows]
Java IDL and RMI-IIOP Tools
These tools are used when creating applications that use OMG-standard IDL and CORBA/IIOP.
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. |
Java Plug-in Tools
Utilities for use in conjunction with the Java Plug-inTM product.
unregbean | Unregisters a packaged JavaBeans component over ActiveX. Unregbean is described on the Java Plug-in Scripting document on the Java Software web site. |
