These tools are the foundation of the JDK. They are the tools you use to create and build applications.rnTool Name Brief Description rnappletviewer Run and debug applets without a web browser. rnApt Annotation processing tool.rnSee Annotation Processing Tool for program annotation processing. rnextcheck Utility to detect Jar conflicts. rnJar Create and manage Java Archive (JAR) files.rnSee Java Archive Files page for the JAR specification. rnjava The launcher for Java applications. In this release, a single launcher is used both for development and deployment.rnThe old deployment launcher, jre, is no longer provided. rnjavac The compiler for the Java programming language.
javadoc API documentation generator.rnSee Javadoc Tool page for doclet and taglet APIs. rnjavah C header and stub generator. Used to write native methods. rnjavap Class file disassemble rnJdb The Java Debugger.rnSee JPDA for the debugger architecture specifications.
Security ToolsrnThese security tools help you set security policies on your system and create applications that can work within the scope of security policies set at remote sites. rnTool Name Brief Description rnkeytool Manage keystores and certificates. rnjarsigner Generate and verify JAR signatures. rnpolicytool GUI tool for managing policy files. rnThese security tools help you obtain, list, and manage Kerberos tickets.rnTool Name Brief Description rnkinit Tool for obtaining Kerberos v5 tickets. Equivalent functionality is available on the Solaris operating system via the kinit tool. For example, for Solaris 11, see the kinit reference page. rnklist Command-line tool to list entries in credential cache and key tab. Equivalent functionality is available on the Solaris operating system via the klist tool. For example, for Solaris 11, see the klist reference page. rnktab Command-line tool to help the user manage entries in the key table. Equivalent functionality is available on the Solaris operating system via the kadmin tool. For example, for Solaris 11, see the kadmin reference page.
Internationalization ToolsrnThis tool helps to create localizable applications. rnTool Name Brief Description rnnative2ascii Convert text to Unicode Latin-1.
Remote Method Invocation (RMI) ToolsrnThese tools help to create applications that interact over the Web or other network. rnTool Name Brief Description rnrmic Generate stubs and skeletons for remote objects. rnrmiregistry Remote object registry service. rnrmid RMI activation system daemon. rnserialver Return class serialVersionUID.
Java IDL and RMI-IIOP ToolsrnThese tools are used when creating applications that use OMG-standard IDL and CORBA/IIOP. rnTool Name Brief Descriptionrntnameserv Provides access to the naming service.rnidlj Generates .java files that map an OMG IDL interface and enable an application written in the Java programming language to use CORBA functionality.rnorbd 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.rnservertool Provides ease-of-use interface for the application programmers to register, unregister, startup, and shutdown a server.
Java Deployment ToolsrnUtilities for use in conjunction with deployment of java applications and applets on the web. rnTool Name Brief Descriptionrnjavafxpackager Packages JavaFX applications for deployment. See Deploying JavaFX Applications for more information.rnpack200 Transforms a JAR file into a compressed pack200 file using the Java gzip compressor. The compressed packed files are highly compressed JARs, which can be directly deployed, saving bandwidth and reducing download time.rnunpack200 Transforms a packed file produced by pack200 into a JAR file.
Java Web Start ToolsrnUtilities for use in conjunction with Java Web Start. rnTool Name Brief Descriptionrnjavaws Command line tool for launching Java Web Start and setting various options.rnSee Java Web Start Guide for more information.
rnTroubleshooting ToolsrnThe following tools can be used for specific troubleshooting tasks. The tools described in this section are unsupported and experimental in nature and should be used with that in mind. They may not be available in future JDK versions. rnSome of these tools are not currently available on Windows platforms.rnTool Name Brief Descriptionrnjinfo Experimental - Configuration Info for Java - Prints configuration information for a given process or core file or a remote debug server.rnjhat Experimental - Heap Dump Browser - Starts a web server on a heap dump file (for example, produced by jmap -dump), allowing the heap to be browsed.rnjmap Experimental - Memory Map for Java - Prints shared object memory maps or heap memory details of a given process or core file or a remote debug server.rnjsadebugd Experimental - Serviceability Agent Debug Daemon for Java - Attaches to a process or core file and acts as a debug server.rnjstack Experimental - Stack Trace for Java - Prints a stack trace of threads for a given process or core file or remote debug server.rnRefer to the Java™ SE Troubleshooting web site for descriptions of tools, options, and other information to use in analyzing problems. The documents at this site contain suggestions about what to try before submitting a bug report and what data to collect for a report.
Scripting ToolsrnThe following tool can be used to run scripts that interact with the Java platform. This tool is unsupported and experimental in nature and should be used with that in mind. It might not be available in future JDK versions. rnTool Name Brief Descriptionrnjrunscript Experimental - Script shell for Java - Runs a script.
