If you are downloading the JDK installer for 64-bit systems for update 9 Minor 1, Security 1, and Patch 1, then the file name jdk-9.minor.security.patch_windows-x64_bin.exe becomes jdk-9.1.1.1_windows-x64_bin.exe.
If you are downloading the JRE installer for 64-bit systems for update 9 Minor 1, Security 1, and Patch 1, then the file name jre-9.minor.security.patch_windows-x64_bin.exe becomes jre-9.1.1.1_windows-x64_bin.exe.
Installed 32-bit Jdk Or Jre Or Download
The following table lists example installation scenarios and the commands required to perform them. The notation jdk stands for the downloaded installer file base name, such as jdk-9_windows-x64_bin.exe.
The private JRE installed with the JDK is not registered. To register the JRE, you must set the PATH environment variable to point to JAVA_HOME\bin, where JAVA_HOME is the location where you installed the private JRE . See Setting the PATH Environment Variable.
If there are two versions of JDK or JRE installed on a system, one with the new version-string format introduced in JDK 9, and the other with the older version format, then there will be two different CurrentVersion registry key values. For example, if JDK 1.8.0 and JDK 9 are installed, then the following registry keys are created:
With Java Web Start, you can download and run applications, such as a complete spreadsheet program or an internet chat client, without going through complicated installation procedures. With Java Web Start, you run applications simply by clicking a web page link. If the application is not present on your computer, Java Web Start automatically downloads all necessary files. It then caches the files on your computer so that the application is always ready to be run anytime that you want - either from an icon on your desktop or from the browser link. No matter which method you use to run the application, the most current, available version of the application is always presented to you.
If you have a previous version of Java Web Start, do not uninstall it. Uninstalling it will cause the download cache to be cleared, and all previously installed Java Web Start application data will have to be downloaded again. The new version will write over previous installations and automatically update browsers to use the new version. The configuration files and the program files folder used by Java Web Start have changed, but all your settings will remain intact after the upgrade because Java Web Start will translate your settings to the new form.
To avoid seeing the misleading message, either press F5 or reopen the dialog box. Any Java Web Start application that was downloaded and cached with the JDK or JRE will no longer appear in the list of currently installed programs.
When the installed JRE falls below the security baseline or passes its built-in expiration date, an additional warning is shown to users to update their installed JRE to the latest version. For businesses that manage the update process centrally, users attempting to update their JRE individually, may cause problems.
A deployment rule set enables enterprises to manage their Java desktop environment directly and continue using legacy business applications in an environment of ever-tightening Java applet and Java Web Start application security policies. A deployment rule set enables administrators to specify rules for applets and Java Web Start applications; these rules may specify that a specific JRE version must be used. Consequently, the Java Uninstall tool will not run if it detects a deployment rule set to ensure that no required JREs are uninstalled.
The JRE bootstrap installer uses the system Internet Connection settings to connect to the web for downloading extra files. If you are behind a firewall and require proxy settings, then ensure that the proxy settings in Internet Options/Internet Properties are set up properly (select Start, then Control Panel, then Internet Options/Internet Properties, then Connections, and then LAN Settings). If you can browse the external web (for example, outside the firewall) with Internet Explorer, then your proxy settings are properly set up. The installer does not understand the proxy settings specified in Netscape/Mozilla.
The message is part of the Java Auto Update mechanism, which detects at user login time if a newer version of the JRE is available for download. In the system tray, click the Java Update icon to download and install the update.
To address these problems, ensure that the third-party downloader applications are turned off and the network connection is configured properly. Also, if a proxy is in use, then ensure that the proxy authentication is turned off.
See Error 1722: Problem with Windows Installer Package. If you encounter any other errors or issues, then you can access Java Help Center, which contains solutions for issues that you might encounter when downloading and installing Java on your system. In particular, you can search for solutions by error number. Searching for "Error 1722" returns a solution to this issue.
If you save the self-installing executable file to disk without running it from the download page at the web site, note that its byte size provided on the download page. After the download has completed, verify that you have downloaded the full, uncorrupted software file.
The file jdk-7-windows-i586-i.exe is the JDK installer for 32-bit systems. The file jdk-7-windows-x64.exe is the JDK installer for 64-bit systems. If you downloaded either file instead of running it directly from the web site, double-click the installer's icon. Then, follow the instructions the installer provides. The installer may ask you to reboot your computer. When finished with the installation, you can delete the downloaded file to recover disk space.
If you see the error message "corrupt cabinet file," then the file you have downloaded is corrupted. Check the file size against the expected file size listed in these instructions. If sizes do not match, try downloading the bundle again. (A cabinet file contains compressed application, data, resource, and DLL files.)
So what does this mean exactly? Base (the database component) relies completely on Java technologies to run, but otherprograms (like Writer, Calc and Impress) only need Java for special functionality. If you do not need to use Base and donot want to use any of the Wizards, then you do not need to have Java installed and configured for running ApacheOpenOffice (and older versions of OpenOffice.org). You can completely prevent OpenOffice from prompting you about the useof Java by telling OpenOffice not to use a Java runtime environment (JRE). From the OpenOffice main menu use:"Tools - Options... - Java", and uncheck "Use a Java runtime environment". However, we do recommendthat you have a JRE on your system to take full advantage of OpenOffice's features without any issues.
You will need to have a JRE version (32-bit or 64-bit) that is compatible with the architecture of the ApacheOpenOffice version you downloaded. If you already have a JRE installed on your system that satisfies this requirement inone of the standard areas for Java installation, OpenOffice should detect this installation and let you choose it for usein OpenOffice via the "Tools - Options... - Java". If you have a JRE installed that is not detected,you should be able to add it through this same menu. And, you can install a JRE or configure OpenOffice to use Java at anytime to get missing functionality to work.
The current versions of Apache OpenOffice work reliably with a variety of JREs includingOracle Java, versions 6, 7 and 8,openJDK, versions 6, 7 and 8 andAdoptium OpenJDK, versions 8 and 11. Feel free to download a JRE from either of these sitesif you feel you need this functionality.
The current version, Apache OpenOffice 3.4, has reported problems with using the 32-bit JRE on 64-bit Windows 7systems. However, this problem can not be reproduced in all cases. Java 1.7 is the latest Java from Oracle.
There are two different Java SE packages that can be installed: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). JRE is an implementation of the Java Virtual Machine (JVM), which allows you to run compiled Java applications and applets. The JDK includes the JRE as well as other software that is required for writing, developing, and compiling Java applications and applets.
The interactions between Java naming conventions and Linux package naming conventions can be somewhat confusing. Earlier in this tutorial, we clarified the difference between the full JDK environment for development, and the JRE environment for running Java applications. Although OpenJDK is the name of the open source distribution of Java, you have only actually installed the OpenJDK JRE. In order to install the full OpenJDK JDK, you should install the corresponding package with -devel appended onto its name. This is a common convention for development packages for other programming environments, which Java also follows, although the terminology overlaps awkwardly here.
As before, you can install the full JDK environment by appending -devel to the package name. However, after this, running java programs will still use the OpenJDK 1.8.0 version that you installed earlier by default, which you can confirm by running java -version again:
If you installed multiple versions of Java, you may want to set one as your default (i.e. the one that will run when a user runs the java command). Additionally, some applications require certain environment variables to be set to locate which installation of Java to use.
For example, if you installed Java to (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-2.el8_5.x86_64/jre/bin (i.e. your java executable is located at (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-2.el8_5.x86_64/jre/bin/java), you could set your JAVA_HOME environment variable in a bash shell or script like so:
Throughout this section we will be using the wget command to download the Oracle Java software packages. wget may not be included by default on your Linux distribution, so in order to follow along you will need to install it by running: 2ff7e9595c
