Runtime Environment |
| 5 |
Version 6 |

|

|
| 8 |
The Java(TM) Platform, Standard Edition Runtime Environment (JRE(TM)), |
| 9 |
excluding the JavaFX(TM) runtime, is intended for software developers |
| 10 |
and vendors to redistribute with their applications. |
| 11 |
|
| 12 |
The Java SE Runtime Environment contains the Java virtual machine, |
| 13 |
runtime class libraries, and Java application launcher that are |
| 14 |
necessary to run programs written in the Java programming language. |
| 15 |
It is not a development environment and does not contain development |
| 16 |
tools such as compilers or debuggers. For development tools, see the |
| 17 |
Java SE Development Kit (JDK(TM)). The JRE installation triggers the |
| 18 |
download of the JavaFX runtime. The JavaFX runtime is also available |
| 19 |
separately, and is not part of the JRE. For information on JavaFX, and |
| 20 |
how to make changes, go to: http://java.com/javafx |

Deploying Applications with the Java SE Runtime Environment |
| 25 |
======================================================================= |
| 26 |
|
| 27 |
When you deploy an application written in the Java programming |
| 28 |
language, your software bundle will probably consist of the following |
| 29 |
parts: |
| 30 |
|
| 31 |
Your own class, resource, and data files. |
| 32 |
The Java SE Runtime Environment. |
| 33 |
An installation procedure or program. |
| 34 |
|
| 35 |
You already have the first part, of course. The remainder of this |
| 36 |
document covers the other two parts. See also the Notes for Developers |
| 37 |
page on the Java Software website: |

| 42 |
Java Platform, Standard Edition Runtime Environment (JRE) |
| 43 |
----------------------------------------------------------------------- |
| 44 |
|
| 45 |
To run your application, a user needs the Java SE Runtime Environment, |
| 46 |
which is freely available from Oracle. Or, you can redistribute the |
| 47 |
Java SE Runtime Environment for free with your application, according |
| 48 |
to the terms of the Java SE Platform Runtime Environment's license. The |
| 49 |
JavaFX runtime is only required to run applications written in the |
| 50 |
JavaFX scripting language; it is freely available from Oracle, and must |
| 51 |
not be redistributed with your application. |
| 52 |
|
| 53 |
The final step in the deployment process occurs when the software is |
| 54 |
installed on an individual user's system. Installation consists of copying |
| 55 |
software onto the user's system, then configuring the user's system |
| 56 |
to support that software. You should ensure that your installation |
| 57 |
procedure does not overwrite existing JRE installations, as they may |
| 58 |
be required by other applications. |

----------------------------------------------------------------------- |
| 113 |
Required vs. Optional Files |
| 114 |
----------------------------------------------------------------------- |
| 115 |
|
| 116 |
The files that make up the Java SE Runtime Environment are divided into |
| 117 |
two categories: required and optional. Optional files may be excluded |
| 118 |
from redistributions of the Java SE Runtime Environment at the |
| 119 |
vendor's discretion. |
| 120 |
|
| 121 |
The following section contains a list of the files and directories that |
| 122 |
may optionally be omitted from redistributions with the Java SE Runtime |
| 123 |
Environment. All files not in these lists of optional files must be |
| 124 |
included in redistributions of the runtime environment. |
| 125 |
|
| 126 |
----------------------------------------------------------------------- |
| 127 |
Optional Files and Directories |
| 128 |
----------------------------------------------------------------------- |
| 129 |
|
| 130 |
The following files may be optionally excluded from redistributions. |
| 131 |
These files are located in the jre1.6.0_<version> directory, where |
| 132 |
<version> is the update version number. Solaris and Linux filenames |
| 133 |
and separators are shown. Windows executables have the ".exe" suffix. |
| 134 |
Corresponding files with _g in the name can also be excluded. |
| 135 |
The corresponding man pages should be excluded for any excluded |
| 136 |
executables (with paths listed below beginning with bin/ , |
| 137 |
for the Solaris(TM) Operating System and Linux). |

Redistributable JDK(TM) Files |
| 222 |
----------------------------------------------------------------------- |
| 223 |
|
| 224 |
The limited set of files from the Java SE Development Kit (JDK) |
| 225 |
listed below may be included in vendor redistributions of the Java SE |
| 226 |
Runtime Environment. All paths are relative to the top-level |
| 227 |
directory of the JDK. The corresponding man pages should be included for |
| 228 |
any included executables (with paths listed below beginning with bin/ , |
| 229 |
for the Solaris(TM) Operating System and Linux). |
| 230 |
|
| 231 |
jre/lib/cmm/PYCC.pf |
| 232 |
Color profile. This file is required only if one wishes to |
| 233 |
convert between the PYCC color space and another color space. |
| 234 |
|
| 235 |
All .ttf font files in the jre/lib/fonts directory. |
| 236 |
Note that the LucidaSansRegular.ttf font is already contained |
| 237 |
in the Java SE Runtime Environment, so there is no need to |
| 238 |
bring that file over from the JDK. |
| 239 |
|
| 240 |
jre/lib/audio/soundbank.gm |
| 241 |
This MIDI soundbank is present in the JDK, but it has |
| 242 |
been removed from the Java SE Runtime Environment in order to |
| 243 |
reduce the size of the Runtime Environment's download bundle. |
| 244 |
However, a soundbank file is necessary for MIDI playback, and |
| 245 |
therefore the JDK's soundbank.gm file may be included in |
| 246 |
redistributions of the Runtime Environment at the vendor's |
| 247 |
discretion. Several versions of enhanced MIDI soundbanks are |
| 248 |
available from the Java Sound web site: |
| 249 |
http://java.sun.com/products/java-media/sound/ |
| 250 |
These alternative soundbanks may be included in redistributions |
| 251 |
of the Java SE Runtime Environment. |
| 252 |
|
| 253 |

| 268 |
bin/amd64/apt [Solaris Operating System (AMD)] |
| 269 |
bin/apt.exe [Microsoft Windows] |
| 270 |
|
| 271 |
lib/jconsole.jar |
| 272 |
The Jconsole application. NOTE: The Jconsole application requires |
| 273 |
the dynamic attach mechanism. |
| 274 |
|
| 275 |
The dynamic attach mechanism consisting of the following files: |
| 276 |
lib/tools.jar [All platforms] |
| 277 |
jre/lib/sparc/libattach.so |
| 278 |

| 286 |
|
| 287 |
The Java Platform Debugger Architecture implementation consisting of the |
| 288 |
files shown in the dynamic attach section above, and the following files: |
| 289 |
lib/tools.jar [All platforms] |
| 290 |
lib/sa-jdi.jar [All platforms] |
| 291 |

| 298 |
[Solaris(TM) Operating System (AMD) and Linux] |
| 299 |
|
| 300 |
jre\bin\server\ |
| 301 |
On Microsoft Windows platforms, the JDK includes both |
| 302 |
the Java HotSpot(TM) Server VM and Java HotSpot Client VM. |
| 303 |
However, the Java SE Runtime Environment for Microsoft Windows |
| 304 |
platforms includes only the Java HotSpot Client VM. Those wishing |
| 305 |
to use the Java HotSpot Server VM with the Java SE Runtime |
| 306 |
Environment may copy the JDK's jre\bin\server folder to a |
| 307 |
bin\server directory in the Java SE Runtime Environment. Software |
| 308 |
vendors may redistribute the Java HotSpot Server VM with their |
| 309 |
redistributions of the Java SE Runtime Environment. |
| 310 |
|
| 311 |

----------------------------------------------------------------------- |
| 313 |
Unlimited Strength Java Cryptography Extension |
| 314 |
----------------------------------------------------------------------- |
| 315 |
|
| 316 |
Due to import control restrictions for some countries, the Java |
| 317 |
Cryptography Extension (JCE) policy files shipped with the Java SE |
| 318 |
Development Kit and the Java SE Runtime Environment allow strong but |
| 319 |
limited cryptography to be used. These files are located at |
| 320 |
|
| 321 |
<java-home>/lib/security/local_policy.jar |
| 322 |
<java-home>/lib/security/US_export_policy.jar |
| 323 |
|
| 324 |
where <java-home> is the jre directory of the JDK or the |
| 325 |
top-level directory of the Java SE Runtime Environment. |
| 326 |
|
| 327 |
An unlimited strength version of these files indicating no restrictions |
| 328 |
on cryptographic strengths is available on the JDK web site for |
| 329 |
those living in eligible countries. Those living in eligible countries |
| 330 |
may download the unlimited strength version and replace the strong |
| 331 |
cryptography jar files with the unlimited strength files. |
| 332 |
|
| 333 |
----------------------------------------------------------------------- |
| 334 |
The cacerts Certificates File |
| 335 |
----------------------------------------------------------------------- |
| 336 |
|
| 337 |
Root CA certificates may be added to or removed from the Java SE |
| 338 |
certificate file located at |
| 339 |
|
| 340 |
<java-home>/lib/security/cacerts |
| 341 |
|
| 342 |
For more information, see The cacerts Certificates File section |

| 348 |
Endorsed Standards Override Mechanism |
| 349 |
======================================================================= |
| 350 |
|
| 351 |
From time to time it is necessary to update the Java platform in order |
| 352 |
to incorporate newer versions of standards that are created outside of |
| 353 |
the Java Community Process(SM) (JCP(SM) http://www.jcp.org/) (Endorsed |
| 354 |
Standards), or in order to update the version of a technology included |
| 355 |
in the platform to correspond to a later standalone version of that |
| 356 |
technology (Standalone Technologies). |
| 357 |
|
| 358 |
The Endorsed Standards Override Mechanism provides a means whereby |
| 359 |
later versions of classes and interfaces that implement Endorsed |
| 360 |
Standards or Standalone Technologies may be incorporated into the Java |
| 361 |
Platform. |
| 362 |
|
| 363 |
For more information on the Endorsed Standards Override Mechanism, |
| 364 |
including the list of platform packages that it may be used to |
| 365 |
override, see |
