Java для Linux

Java — один из языков программирования, который был разработан организацией Sun Microsystems, впоследствии выкупленной компанией Oracle. Программное обеспечение, которое пишется на данном языке нацелено на взаимодействие с любыми ОС, то есть они кроссплатформенные. Чтобы запускать подобные программы необходимо установить в ОС компьютера специальную виртуальную машину Джава (Java Virtual Machine — JVM), другими словами, специальный компонент, обеспечивающий работу программного обеспечения, написанного на языке Ява.

Загрузка программы

Версии и их различия

Существуют разные возможные вариации Джава для Линукс. Наиболее распространённые — OpenJDK и Oracle Java. Обычно в Linux используются именно эти реализации:

• Oracle Java — вариация программного обеспечения. Она содержит закрытые и открытые составляющие, защищённые патентами;
• OpenJDK — вариация Ява для Linux, содержащая открытый код.

И та и та вариации будут оптимальными в ОС Linux, поэтому можно пользоваться любой. Однако, некоторые приложения рекомендуют выбрать именно Oracle.

Два пакета, которые есть для Linux:

• 1. JRE— составляющие, способствующие работе Ява-программ в Линукс;
• 2. JDK— составляющие, способствующие работе, компиляции и разработке программ.

Что нужно устанавливать в Linux

Всё, что необходимо для рядового пользователя, если он хочет работать с ПО на языке джава, установить «OpenJDK JRE». Если вдруг есть потребность в компиляции, необходима установка «OpenJDK JDK».

То есть, если вы хотите открывать Ява в Линукс, устанавливайте OpenJDK JRE.

Команды для установки

# sudo mkdir /usr/lib/jvm

# sudo tar -zxf /home/username/Загрузки/tarname -C /usr/lib/jvm

Установка в систему

# sudo update-alternatives —install «/usr/bin/java» «java» «/usr/lib/jvm/foldername/bin/java» 1500 # sudo update-alternatives —install «/usr/bin/javaws» «javaws» «/usr/lib/jvm/foldername/bin/javaws» 1500

# sudo nano /etc/environment

Добовляем в /etc/environment следующее:

Для применения изменении без перезагрузки

Запуск программ

Если в вашей системе Линукс уже установлены необходимые компоненты Джава, останется только два раза нажать на ярлык приложения для его запуска. Если планируете запуск jar-файла, воспользуйтесь командной строкой и введите следующее: java -jar ./myprogram.jar.

Заключение

В данной статье мы вкратце разобрались с программным обеспечением Джава и компонентами, необходимыми для корректной работы программ, необходимым для системы Линукс. Мы постарались понятным языком объяснить, что необходимо обычному пользователю для работы с программным обеспечением Ява.

Java linux 32 bit download

This procedure installs the Java Development Kit (JDK) for 32-bit Linux, using a self-extracting binary file. The JDK download includes the Java SE Runtime Environment (JRE) – you do not have to download the JRE separately.

For RPM-based Linux distributions, like Red Hat or SuSE, refer to the RPM installation instructions.

The name of the downloaded file has the following format:

To install, download this file and use the following instructions.

Download and check the download file size.

You can download to any directory that you can write to.

This bundle can be installed by anyone (not only root users), in any location that the user can write to. However, only the root user can displace the system version of the Java platform supplied by Linux.

Make sure that execute permissions are set

Run this command:

% chmod a+x jdk-6u -linux-i586.bin

Change directory to the location where you would like the files to be installed.

The next step installs the JDK into the current directory.

Run the self-extracting binary.

Execute the downloaded file, prepended by the path to it. For example, if the file is in the current directory, prepend it with » ./ » (necessary if » . » is not in the PATH environment variable):

% ./jdk-6u

The binary code license is displayed, and you are prompted to agree to its terms.

The JDK files are installed in a directory called jdk1.6.0_ in the current directory. Follow this link to see its directory structure. The JDK documentation is a separate download.

Note about Root Access: Installing the software automatically creates a directory called jdk1.6.0_ . Note that if you choose to install the JDK into a system-wide location such as /usr/local , you must first become root to gain the necessary permissions. If you do not have root access, simply install the Java SE Runtime Environment into your home directory, or a subdirectory that you have permission to write to.

Note about Overwriting Files: If you install the software in a directory that contains a subdirectory named jdk1.6.0_ , the new software overwrites files of the same name in that jdk1.6.0_ directory. Please be careful to rename the old directory if it contains files you would like to keep.

Note about System Preferences: By default, the installation script configures the system such that the backing store for system preferences is created inside the JDK’s installation directory. If the JDK is installed on a network-mounted drive, it and the system preferences can be exported for sharing with Java runtime environments on other machines.

See the Preferences API documentation for more information about preferences in the Java platform.

Java SE JDK and JRE 8.301

Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. This new version is considered a Critical Patch Update.

It’s also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing. Installing this update will ensure that your Java applications continue to run as safely and efficiently as always.

The JRE is the Java Runtime Environment, it covers most end-users needs. Contains everything required to run Java applications on your system. It is a package of everything necessary to run a compiled Java program, including the Java Virtual Machine (JVM), the Java Class Library, the java command, and other infrastructure. However, it cannot be used to create new programs.

The JDK is the Java Development Kit, the full-featured SDK for Java. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). It is capable of creating and compiling programs.

Usually, if you only care about running Java programs on computer you will only install the JRE. It’s all you need. On the other hand, if you are planning to do some Java programming, you need to install the JDK instead.

Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Why would you need the JDK then? Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets.

Allow SASL Mechanisms to Be Restricted

• A security property named jdk.sasl.disabledMechanisms has been added that can be used to disable SASL mechanisms. Any disabled mechanism will be ignored if it is specified in the mechanisms argument of Sasl.createSaslClient or the mechanism argument of Sasl.createSaslServer. The default value for this security property is empty, which means that no mechanisms are disabled out-of-the-box.

SunPKCS11 Provider Upgraded with Support for PKCS#11 v2.40

• The SunPKCS11 provider has been updated with support for PKCS#11 v2.40. This version adds support for more algorithms such as the AES/GCM/NoPadding cipher, DSA signatures using SHA-2 family of message digests, and RSASSA-PSS signatures when the corresponding PKCS11 mechanisms are supported by the underlying PKCS11 library.

New Checks on Trust Anchor Certificates

• New checks have been added to ensure that trust anchors are CA certificates and contain proper extensions. Trust anchors are used to validate certificate chains used in TLS and signed code. Trust anchor certificates must include a Basic Constraints extension with the cA field set to true. Also, if they include a Key Usage extension, the keyCertSign bit must be set.
• A new system property named jdk.security.allowNonCaAnchor has been introduced to restore the previous behavior, if necessary. If the property is set to the empty String or «true» (case-insensitive), trust anchor certificates can be used if they do not have proper CA extensions.
• The default value of this property, if not set, is «false».
• Note that the property does not apply to X.509 v1 certificates (since they don’t support extensions).
• This property is currently used by the JDK implementation. It is not guaranteed to be supported by other Java SE implementations.

Exact Match Required for Trusted TLS Server Certificate

• A TLS server certificate must be an exact match of a trusted certificate on the client in order for it to be trusted when establishing a TLS connection.

Added LuxTrust Global Root 2 Certificate

The following root certificate has been added to the cacerts truststore:

+ LuxTrust
+ luxtrustglobalroot2ca
DN: CN=LuxTrust Global Root 2, O=LuxTrust S.A., C=LU

Bug Fixes:

Support for OpenType CFF Fonts

• Previously, Oracle JDK 8 did not include OpenType CFF fonts (.otf fonts) into the standard logical fonts (such as «Dialog» and «SansSerif»). This resulted in missing glyphs when rendering text. In the most extreme cases where only CFF fonts were installed on the system, a Java exception could be thrown.
• Several Linux distributions were affected by this issue because they rely on CFF fonts to support some languages, which is common for CJK (Chinese, Japanese, and Korean) languages.
• Oracle JDK 8 now uses these CFF fonts, and this issue has been resolved.

Better Serial Filter Handling

• The jdk.serialFilter system property can only be set on the command line. If the filter has not been set on the command line, it can be set can be set with java.io.ObjectInputFilter.Config.setSerialFilter. Setting the jdk.serialFilter with java.lang.System.setProperty has no effect.
