TheOracle Technology Network License Agreementfor Oracle Java SE is substantially different from prior Oracle JDK 8 licenses. This license permits certainuses, such as personal use and development use, at no cost -- but other uses authorized under prior Oracle JDKlicenses may no longer be available. Please review the terms carefully before downloading and using this product.FAQs are availablehere.
These downloads can be used for development, personal use, or to run Oracle licensed products. Use for otherpurposes, including production or commercial use, requires a Java SE subscription or another Oracle license.
If you still want to use an old version you can find more information in the Maven Releases History and can download files from the archives for versions 3.0.4+ and legacy archives for earlier releases.
If you have downloaded Fiji or ImageJ2 quite some time ago (before 2016), you probably have the Java 6 version (how do I find out?). So when you update, you will not receive the latest plugin releases anymore, as described above.
I installed the jdk 1.6u7, and then I open firefox, I see there is a java console 6.0.07 in extension, but in plugins, there is no java. and I can't open java website, it shows I don't install java in my machine, but actually, I have installed jdk 1.6u7. I think only if the java exists in plugins, the website can get the jvm and run.
You would need JRE (Java Runtime Environment) to run Java programs. You can try to click the download button on the page (above image) or you can download the latest version here: -downloads-1637588.html
I download the jdk file: jdk-6u7-windows-i586-p.exe, after I click it and install, it installed both the jdk and jre, I can see 2 folders: C:\Program Files (x86)\Java\jdk1.6.0_07 and C:\Program Files (x86)\Java\jre1.6.0_07.
The Java Update feature lets you check for updates from the Java (32-bit) Update tab in Windows Control Panel. To update java manually, go to and download the latest version of Java, currently Java 7 Update 5, then close Firefox and run the installer. You will then see Java(TM) Platform SE 7 U5 in the Firefox Add-ons Manager Plugins list when you next open Firefox. You can check your Java version using the test links here.
The javac tool reads class and interface definitions, written in the Java programming language, and compiles them into bytecode class files. It can also process annotations in Java source files and classes.
Source code file names must have .java suffixes, class file names must have .class suffixes, and both source and class files must have root names that identify the class. For example, a class called MyClass would be written in a source file called MyClass.java and compiled into a bytecode class file called MyClass.class.
You should arrange source files in a directory tree that reflects their package tree. For example, if you keep all your source files in C:\workspace, the source code for com.mysoft.mypack.MyClass should be in C:\workspace\com\mysoft\mypack\MyClass.java.
Note: CLASSPATH, -classpath, -bootclasspath, and -extdirs do not specify the classes used to run javac. Fiddling with the implementation of the compiler in this way is usually pointless and always risky. If you do need to do this, use the -J option to pass through options to the underlying java launcher.
By default, classes are compiled against the bootstrap and extension classes of the platform that javac shipped with. But javac also supports cross-compiling, where classes are compiled against a bootstrap and extension classes of a different Java platform implementation. It is important to use -bootclasspath and -extdirs when cross-compiling; see Cross-Compilation Example below.
To shorten or simplify the javac command line, you can specify one or more files that themselves contain arguments to the javac command (except -J options). This enables you to create javac commands of any length on any operating system.
An argument file can include javac options and source filenames in any combination. The arguments within a file can be space-separated or newline-separated. If a filename contains embedded spaces, put the whole filename in double quotes, and double each backslash ("My Files\\Stuff.java").
Filenames within an argument file are relative to the current directory, not the location of the argument file. Wildcards (*) are not allowed in these lists (such as for specifying *.java). Use of the '@' character to recursively interpret files is not supported. The -J options are not supported because they are passed to the launcher, which does not support argument files.
When executing javac, pass in the path and name of each argument file with the '@' leading character. When javac encounters an argument beginning with the character `@', it expands the contents of that file into the argument list.
Unless annotation processing is disabled with the -proc:none option, the compiler searches for any annotation processors that are available. The search path can be specified with the -processorpath option; if it is not given, the user class path is used. Processors are located by means of service provider-configuration files named META-INF/services/javax.annotation.processing.Processor on the search path. Such files should contain the names of any annotation processors to be used, listed one per line. Alternatively, processors can be specified explicitly, using the -processor option.
For example, when you subclass java.applet.Applet, you are also using Applet's ancestor classes: java.awt.Panel, java.awt.Container, java.awt.Component, and java.lang.Object.
Note that all other classes and methods found in a package whose name starts with com.sun.tools.javac (informally known as sub-packages of com.sun.tools.javac) are strictly internal and subject to change at any time.
The -source 1.6 option specifies that version 1.6 (or 6) of the Java programming language be used to compile OldCode.java. The option -target 1.6 option ensures that the generated class files will be compatible with 1.6 VMs. Note that in most cases, the value of the -target option is the value of the -source option; in this example, you can omit the -target option.
I'm not allowed to change the POM file, so I had to do some jiggery pokery. I copied the tools.jar from my Java 6 JDK, created the directory C:\java\lib and pasted it there. I then restarted eclipse and cleaned my project. And VOILA errors are gone.
The directory "C:\ProgramData\Oracle\Java\javapath" is present in PATH environment variable and contains shortcuts to the java, javaw etc...The target for these shortcuts were all JRE 1.8. (This I think was the main problem)I changed the shortcuts to point to the correct JDK exe's.
Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-04T20:00:29+01:00) Maven home: C:\Program Files\Apache\maven-3.6.1 Java version: 1.8.0_221, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jre1.8.0_221 Default locale: en_GB, platform encoding: Cp1252 OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
We can see maven gets the java runtime path as "C:\Program Files\Java\jre1.8.0_221" if you don't specify JAVA_HOME environment variable. And then maven assumes this path to be JAVA_HOME. That's why when building the application either from command prompt or any IDE, maven looks for tools.jar file in path "%JAVA_HOME%..\lib\tools.jar".
Using JMRI requires a combination of hardware (in this case running Windows), Java software and a JMRI download for a specific version. The table below shows configurations that have been reported working - there may be other combinations that are also possible, but they have not been reported by the user community. JMRI Release Windows Rel. Java Rel. Test release 4.x.y through 4.25.9 7, 8, 10, 11, Vista Java 1.8 ("Java 8") Production rel 4.26 7, 8, 10, 11 Java 8 or Java 11 (Recommended) Production rel 4.26 Vista Java 8 Test rel 4.27.1 7, 8, 10, 11, Vista Java 8 or Java 11 (Recommended) Test rel 4.99.x 8.1, 10, 11 Java 11 Production rel 5.0 8.1, 10, 11 Java 11 Test rel 5.x 8.1, 10, 11 Java 11 Older releases: JMRI Release Windows Rel.

During the installation your machine will be checked for java 11 or greater. First it will check the default version, then if that fails search the registry entries (javasoft keys).
If java 11 or greater is not found it will ask you whether you wish to continue the installation. Continuing permits you to resolve this issue later by either installing a valid version or linking JMRI to an absolute version as described in Using a specific java version section below.
JMRI also supports an offline installation - to set up, refer to the Offline Installation section below.The JMRI project is continuously adding features, bug fixes, examples and tutorials to the release, and sonew "Test" versions appear every couple of weeks. You may find one of these has features that you really want.These are announced in the JMRI users Groups.io group.
Run the JMRI installer When the JMRI download is ready, you will be asked to either save it to disk or directly run the installer. [NOTE: illustrations below are not all from the same release, but should be similar to what you see.] Installer start-up
Check for a previous version It will then check to see if a previous version of JMRI exists, backup any Preference, Roster and other settings and, if necessary, uninstall the old JMRI version. You may choose to have the installer make a backup of the existing files, and provide a location on disk for this set.
In some circumstances, the removal of JMRI version 2.5.1 or earlier might fail, resulting in a messageUninstaller failedIn such cases, it is necessary to download and run the following file and then re-run the installer: RemoveOldJMRIUninstallEntry.exe
Choose Users If supported by your Windows version and depending on the permissions of your user, the installer may ask you to choose to install JMRI just for yourself or for all users of the computer.
Choose Components The installer will now present a list of the components to be installed. This will install JMRI to the default location, place shortcuts for DecoderPro and PanelPro on the desktop and create a JMRI Start Menu folder containing shortcuts for typically used JMRI programs. If you wish to change where JMRI is installed, change the install type from 'Typical' to 'Custom (select to choose program folder)' using the drop-down menu.
Choose Install Location The next screen suggests a place for the install.
Choose Start Menu Folder The following screens lets you choose a place for JMRI in your Start menu.
Check for Java The installer will check for a suitable version of Java on your computer and, if required, will alert you to which version of Java should be installed. For example, although these messages may change based on the version of JMRI you are attempting to install. See the tables above for information about which Java is currently recommended for your version of JMRI and see the JMRI Java Recommendations page for information about downloading Java.
Install files Once existence of a suitable Java Runtime Environment has been confirmed, it will then install the needed libraries, plus add a "JMRI" program group to your Start menu and put shortcuts to the DecoderPro and PanelPro programs on your desktop. Click Next.
Installation is complete
Using a specific java version To use a specific java installation either install that version to the JMRI install directory \jre or link the specific java version to the JMRI install directory \jre 2ff7e9595c
