If you are installing ImageJ2 on Windows, we strongly recommend that you storeyour ImageJ2.app directory somewhere in your user space(e.g., C:\Users\[your name]\ImageJ2.app) rather than in C:\Program Files orother system-wide directory. If you move ImageJ2.app to such a directory, modernversions of Windows will deny ImageJ2 write permission to its own directorystructure, preventing it from being able to update. See alsoimagej/imagej#72.
Note: Affected computers may report back as 'Pending Restart' once the patch has run successfully, but will not report back their final status until the computer has been restarted. Important Note: The Java Runtime Environment update does not remove versions of JRE older than JRE 6 update 111. Multiple versions of JRE may be present on affected computers after applying the action below.

The instructions below provide a guide to install the official Oracle JDK 6. You will need to regularly update this manually to ensure your installation maintains recommended security and stability fixes.
Oracle JDK 6 is no longer maintained. It is not updated with the latest security patches and are not recommended for use in production.You can however still download them from the Oracle Java Archive
The version here installed can be updated easily by copying the new version over the currently installed files. Just extract the package and copy over the new one over the one that is currently installed.
I expect, that the ppa of ferramroberto might not be working in the future, because repackaging of java is not allowed any more. Unfortunately what is not allowed for canonical is also not allowed for any other packager. So the solution mentioned above might be the only way (which is basically a wrapper for update-alternatives!):
It is generally a good idea, to get an oracle account and get the java newsletter to be informed about software updates until a solution comes along the way for us ubuntu users to be informed about updates.
IBM SDK, Java Technology Edition, Version 8 contains the latest virtual machine technology from IBM. Downloads contain the latest IBM fixes and Oracle updates to the Java SE 8 application programming interfaces (APIs).
No up-to-date Macintosh should have any problem with DrJava. By update-to-date we mean running Snow Leopard or Lion, and updated with the latest available software updates. If you are not up to date, try that first.
Visit the Oracle download page for JDK 6 Update 30. Any relatively recent version of JDK 6 should be fine, but under no circumstances should you download JDK 7. JDK 7 is not supported by DrJava. The download should not to ask you to make an Oracle account. It if does, please let us know.
If you are still having problems, it is likely that some old version of Java on your system is causing problems. Perhaps you took this (or a similar class) previously. Or you downloaded a cool game that needed Java. Whatever the case, it is time to purge your system of those old Java versions.
I updated my OS from Windos SP2 to SP3(32bit) still the same message "CA of the certificate is not trusted. Use certificate issued by a trusted CA" showing please suggest some solutions.
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.
Edited 2013-01-11: And the world keeps on turning (2012-12-21 notwithstanding), and lo and behold, JRE 6 is about to reach its end of support. Oracle says no more public updates to Java 6 after February 2013.
Edited 2015-04-29: And with another couple of revolutions around the sun, the time has come for the end of support for Java SE 7, too. In April 2015, Oracle affirmed that it was no longer providing public updates to Java SE 7. The tentative end of public updates for Java SE 8 is March 2017, but that end date is subject to change (later, not earlier).
Java SE Runtime is for end user, so you need Java JRE version, the first version of Java was the 1, then 1.1 - 1.2 - 1.3 - 1.4 - 1.5 - 1.6 etc and usually each version is named by version so JRE 6 means Java jre 1.6, anyway there is the update version, for example 1.6 update 45, which is named java jre 6u45.
Since 15th March 2014 this cookie is provided to the user after accepting the License Agreement and is necessary for accessing the Java packages in download.oracle.com. The previous (and first) implementation in 27th March 2012 made use of the cookie gpw_e24=http%3A%2F%2Fwww.oracle.com[...]. Both cases remain unannounced to the public.
Downloading Java from the command line has always been troublesome. What I have been doing reciently is to use FireFox (other browsers might work) to get a download started on my laptop, pause it (within the Downloads windows), use the "Copy Download Link" menu item of the context menu displayed for the downloading file. This URL can then be used on the Linux box to download the same file. I expect the URL has a short time to live. Ugly, but generally successful.
Oracle has put a prevention cookie on the download link to force you to agree to the terms even though the license agreement to use Java clearly states that merely by using Java you 'agree' to the license..
Instead of using for every new Java version a new link or changing existing scripts, I was looking for a more generic way to automate the download of the required Java packages and later installation via yum localinstall $JAVA_ENVIRONMENT-$JAVA_VERSION-linux-x64.rpm.
I've used a somehow trivial approach similar to manual/user action to find the package and to download it. I am also pretty sure that one will find a more elegant way to do it by using other tools like egrep, awk, etc.., so leave it as an example here:
Oracle provide persistent links to the latest updates of each Java version as documented at _afrLoop=397248601136938&id=1414485.1 - though you need to create/log in to an Oracle Support account. *Otherwise you can only access the last "public" update of each Java version, e.g. 1.6_u45 (Mar 2013; Latest update is u65, Oct 2013)*
I've made a jdk-download script (specific for the tar.gz) for my gentoo boxes. Doesn't need to be updated like other similar scripts, trying to "brute-force" download the latest build for whatever version you want.
2) This script in turn calls various other scripts - one of them being create_mirror_misc.sh; this script refers to pnda-static-file-dependencies.txt which has a list of files to be downloaded.
3) On the very first line of the pnda-static-file-dependencies.txt is a reference to download the jdk-8u131-linux-x64.tar.gz file from -pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz oraclelicense=accept-securebackup-cookie; It is at this point that my script was failing with the message Failed to download -pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz after 3 retries
4) I browsed to the page -pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz and found the following error message displayed **In order to download products from Oracle Technology Network you must agree to the OTN license terms**
This happens because when you click the "Accept" button on the download page in your browser, the webpage saves a cookie that it uses to check your agreement before letting you download the file. The problem occurs when trying to download from the command line using wget and it's because there's no cookie information sent with the wget request for downloading the file so from the file server's perspective, you're a completely new user who hasn't accepted the license agreement.
One solution is to send cookie information using the --header option of the wget utility (as shown above in other answers). Ideally if some content is protected, you'd use the various session management options available with wget. For this particular problem however, it's solved (currently) by sending the Cookie header with the download request.
Regarding Oracle Java SE Support Roadmap,[3] version 20 is the latest one, and versions 17, 11 and 8 are the currently supported long-term support (LTS) versions, where Oracle Customers will receive Oracle Premier Support. Java 8 LTS the last free software public update for commercial use was released by Oracle in March 2022, while Oracle continues to release no-cost public Java 8 updates for development[3] and personal use indefinitely.[4] Java 7 is no longer publicly supported. For Java 11, long-term support will not be provided by Oracle for the public; instead, the broader OpenJDK community, as Eclipse Adoptium or others, is expected to perform the work.[5] 2b4c41e320
