Where can I get the latest jdk as a zip file. I don't want the jre, I want the full jdk. I can't run exe's or even request windows installer so it's impossible for me to download the .exe and run it. Also I can't access some uploading sites like Drop box or 4shared. Is there any ftp or place that I can get just zipped up jdk? Thanks you very much. Jportable is not good enough, Thanks.
http://installbuilder.bitrock.com/java/ all the version are available. enjoy. all are ZIP
Ideally, Oracle would provide us with the option of downloading the JDK binaries as a ZIP package instead of forcing us to use the Windows installer. But since they don't, why don't you try downloading the ZIP distribution of another Oracle product that already includes a JDK (e.g. Oracle SQLDeveloper). And please be sure to come back here and let us know if this approach worked out for you. I'm sure there are tons of folks out there looking for workaround too.
It's really simple but, you have to make it yourself.
First, download the JDK from the Oracle Website.
Second, extract all the contents using 7zip or other extracting utility.
Third, navigate through the extracted content and use Java's "unpack200" to convert all the ".pack" files (there's a couple of them) into jar files. You can delete the ".pack" files afterwards if desired.
Note: In order to use unpack200 you need to have a JDK installed on the system. Navigate to the jdk1.x.x_xx/bin folder an run the utility from the command line.
Example: unpack200 rt.pack rt.jar
Thanks.
You can install jdk (with installer, uncheck 'public jre' option), zip installation folder.
Then uninstall jdk. Now you have a jdk zip, you can unzip wherever.
I'm using jdk this way on Windows Vista, both jdk 1.6, and 1.7.
I was also facing the same issue - to get a zip version of JDK7 on my PC. Tried to extract the exe installer and was happy to find that I got a set of folders including jdk,jre, lib,bin etc (similar to the set up that you get by running the installer for Jdk8). But my happiness was short lived - Eclipse did not recognize this path as a valid JDK / JRE installation , while I set up the additional Run time environments.
The fix is to run the exe installer and install it in a different path , outside Program files, so that it doesnt mess up your Java home settings or JRE versions for other client programs.

I am trying to install mingw-w64 onto Windows. However I receive an error, "the file has been downloaded incorrectly". Redownloading the setup file again from sourceforge does not fix the problem. Is there an alternative way to install it or am I doing something wrong?
Old post but same problem, the installer doesn't seem to work.
I give the solution which works for me
You can directly download the archive of MinGW64 with your chosen configuration :
https://sourceforge.net/projects/mingw-w64/files/mingw-w64/
Once the compressed file downloaded, you have just to extract and copy/paste the MinGW64 folder( with the pre-compiled librairies) to your chosen folder ( in my case : C:\mingw64)
I got same error and solved it, after struggling a few hours. You should download MinGW64 via https://winlibs.com/#download-release.
After downloading, You should unzip mingw64 file to a folder(in my case I unzipped it to c disk; C:\mingw64)
And then you have to set up path. for that follow below steps;
open settings.
Search for Edit environment variables for your
account.
choose path variable and then select edit.
Select New and add the Mingw-w64 folder path(bin folder). In my case, I added (C:\mingw64\bin).
Select OK to save the updated path.
And reopen your cmd, then check if everything is good by typing; gcc --version
Long story short, the official installer is broken and not been fixed for years, so we have to install it manually.
The official download link above would bring you to sourceforge: https://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win32/Personal Builds/mingw-builds/installer/mingw-w64-install.exe
And in the same folder that contains the installer, there's a repository.txt. (about this file)
Take a look at it, the installer basically just download and unzip the build from one of these urls within repository.txt. Choose the url you want and download/upzip it manually. (In my case, I use 8.1.0|x86_64|posix|seh|rev0 setup)
Last, setup the Path environment variable pointing to your unzipped bin folder, let say C:\mingw64\bin, and this should do the trick.
Finally, I solved this problem by downloading this:http://winlibs.com/
GCC 10.1.0 + LLVM/Clang/LLD/LLDB 10.0.0 + MinGW-w64 7.0.0 - release 3 (LATEST)
Win32: 7-Zip archive* | Zip archive
Win64: 7-Zip archive* | Zip archive
and set the %path%
After that, I still can't execute gcc correctly, but then I solved the problem by adding this environment variable:
"CGO_ENABLED=1"
I encountered the problem when using this golang package: https://github.com/mattn/go-sqlite3
I received the same error. When I re-ran the installer as an adminstrator it was installed successfully.
I also made sure not to add any spaces to the installation path.
Following this tutorial helped me manually install MinGW for windows : youtube
So the problem for me was that when I tried to use the .exe installer, it either showed me that,
"the file has been downloaded incorrectly" , or , the /.../bin folder did not have any files in it.
In the link above, the MinGW files (including the /bin files) were manually downloaded and identified properly by the Environment Variables.
The problem is with your internet connection and/or ISP. I'm not great at networking so I'll let others be more specific. I tried installing/downloading it using my mobile's data as wifi hotspot and it worked. Hope it helps
I installed the JDK8u40, but only find the javafx-src.zip.
Where can I find the source code for JDK? The src.zip?
Below is what I get after installation:
And btw, I didn't see the installation wizard! This is quite strange.
ADD 1
Today I tried several Java installation packages. All are downloaded from Oracle official site.
jdk-6u45-windows-i586.exe
jdk-7u75-windows-i586.exe
jdk-8u20-windows-i586.exe
jdk-8u25-windows-i586.exe
jdk-8u31-windows-i586.exe
jdk-8u40-windows-i586.exe
Both 6u45 and 7u75 installed well on my box. I can see the install wizard. And the src.zip is installed.
But 8u25 ~ 8u40 all installed silently. And no src.zip file is installed because I have no chance to select it in the wizard.
I am not sure if this is my fault or someone at Oracle made a mistake.
As #SubOptimal commented, the /s option indicates a silent install. I am wondering if there's an option to force the GUI install wizard to open.
I am using Windows 7 Enterprise x64 Build 7601 SP1
Make sure the Source code is not disabled when downloading.
Then as you can see on the picture, selecting "Source Code" will tell you exactly where it is located.
Notice that I've downloaded the 32 bits version to make sure to reproduce the same use case as you.
Edit
As per your new edits and comments, it seems what you want to know now is why you don't see the installation wizards. I'm pretty sure this is due to old-set registry key.
Run the following command
reg query hklm\software\microsoft\windows\currentversion\installer\UserData\S-1-5-18\Products /f "java" /s | find "HKEY_LOCAL_MACHINE"
Now, navigate to each of the returned path browsing with regedit and delete their entire parent (the big hexa number).
Re-try the installation and I'm pretty sure you will see the wizard.
As for the sources, Oracle documentation specify how to download them in silent mode.
jdk.exe /s ADDLOCAL="SourceFeature"
This is the way I got the src folder from jdk-8u172-windows-x64.exe file without installing.
Step1: Download jdk-8u172-windows-x64.exe file (Java SE Development Kit 8u172) from oracle site
Step2: Extract it and navigate to the path:
\jdk-8u172-windows-x64.rsrc\1033\JAVA_CAB9
Step3: Right click on file named "110" and extract it.
You will get the src.zip file.
It took me little while to figure this out. I hope it will help others.
Enjoy debugging Good Code!
I don't know why/where the src.zip is, but as an alternative, if all you want is the source and somehow the proposed method doesn't work for you, you could always pull directly from the JDK8u40 source tree.
You will need Mercurial instead of Git. This link talks about the hg clone command
Quoting from the OpenJDK Java.net site
The corresponding master forest jdk8u can be cloned using this command: hg clone http://hg.openjdk.java.net/jdk8u/jdk8u;cd jdk8u;sh get_source.sh .
In addition, the source code for the last release, 8u40, is available by cloning the 8u40 master forest : http://hg.openjdk.java.net/jdk8u/jdk8u40. The final build of that release was tagged as jdk8u40-b25.
There are differences between OpenJDK and Oracle's, though subtle
download JDK 8 from following link
http://www.oracle.com/technetwork/java/javase/jdk-8-readme-2095712.html
src.zip comes in-built with it
if you JDK installer silently skips installing the source. just open the control panel > programs an features and find Java. Right click on it and select change and then select the
source (option) ;)
Download the JDK
Run the Installer, but stop right away
Extract src.zip from C:\Users\<your_username>\AppData\LocalLow\Oracle\ss180121.cab
You can extract .zip from .cab with tool like 7Zip

I have created a Java application. And its ready for deployment.
I have made jar file from my code. wrapped it using launch4j and bundled jre with it and accessing my exe file(generated by launch4j).
So,No need to install JRE and Everything works fine.
But one small problem is that my Exe file has to be at some predefined relative path to the Bundled JRE.
For example let say user has installed it in E:/(My Soft) where My soft contains JRE files an my Exe file. Now if user copies the exe file to his desktop then he will not be able to execute it.
So, I want to is there any way i can bundle jre within my exe or any other tweek so that user can Execute the exe file from anywhere on his pc ?
Try use jnlp starter for your programms. Read more in official oracle documentation JNLP
There's one option to bundle JRE with exe is to create a Portable Edition app with for example jPortable. So you can execute exe anywhere on the PC without installing JRE. But the better option is to create a custom installer which will check current installation of JRE in the client PC and install it as an required option if no other compatible JRE found.
Is there a way to prevent that the Java installation routine (e.g. jdk-7u1-windows-i586.exe) copies java.exe into C:\Windows\system32 directory?
I have to install my software on a client's laptop and I don't want to break other Java applications which are already installed on the machine. In other words I want to install a private JRE which is only used by my software.
By now, I copied an already installed JRE from my computer to the client's machine.
I discovered yesterday that there is a problem with Java versions on Windows, as you know keeping java up to date these days is critical, especially the JRE used by Internet explorer located in the Windows system32 or syswow64 folder.
You can perform a search for java in your C: drive and look at the various executable files it finds to determine if the situation applies on a specific system.
After doing some research I find that when the Java updater runs, it only updates the files installed in the JAVA home , usually located on the program files, but it does NOT update the files located in the windows system folder. As a result and since the system folder is in the default system PATH , the usage of Internet Explorer continues to use an old version of the JAVA files ( java.exe , javaw.exe , javaws.exe )
The solution is to uninstall java using the control panel uninstall programs feature, download most recent version and install again.
Cheers!

I recently upgraded to java 8 and discovered this problem as the java version under system32 was still java 7. It stops you even running version as it complains about the registry keys
U:\>java -version
Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion'
has value '1.8', but '1.7' is required.
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.
Doing the following pointed me to the culprit:
U:\>where java
C:\Windows\System32\java.exe
C:\Program Files\Java\jdk1.8.0_45\bin\java.exe
I 'solved' this problem by just deleting the java under system32! I'm unsure of what consequences this will have.
You can just provide the JRE you want to use on your software and:
Set the JAVA_HOME variable before you run your application
Point to the correct java.exe file (e.g. ..\jre1.5.0_22\bin\java <your_java_main>)
This can be done in a *.bat file for example.
After running the *.bat file you created, all other java version will be ignored and it won't matter which versions are, or will be, installed on that pc.
I found the newest JDK still doesn't write correct code against registry.
The issue is if a computer doesn't have JRE, JDK doesn't register JRE in registry correctly.
For those install JDK 1.7u72 Just add Software\JavaSoft\Java Runtime Environment as the error message indicate. And add a string entry of CurrentVersion with value 1.7.
And then add Software\JavaSoft\Java Runtime Environment\1.7 and put a JavaHome string entry with value "C:\Program Files\Java\jre7". And JRE will function correctly.
Blame Oracle, if you use Registry, then write correct code, otherwise don't use the Registry!
All you have to do is go to Control Panel -> Programs Uninstall a program. Uninstall the old java updates and keep the newest java update and java development kit update. Your newest java update and java development kit update should have the same number.
Windows 10 Solution
Check Java Version in Console (CMD) with java -version
Check in Console (CMD) with where java, which Java Path's are enlisted.
If it you shows you "C:\Windows\System32" in its output, you will have a problem to get to your %JAVA_HOME%, where your wanted Java version resides.
Meaning, you need to get rid of "java.exe" in "C:\Windows\System32".
Just uninstall the JRE in the Software ("Programs and Features")
Hint: Keep in mind, do NOT the JDK, here in my case "Java SE Development Kit 8 Update (64-bit)"), but the JRE.
One way I would try would be to create a write-only empty file with the name java.exe into the System32 folder.
A project I am working on requires an old version of SLAPD (the LDAP
server) and must run on Windows, hence I am using cygwin packages:
I've found a binary package of slapd version I need 2.2.x here:
http://www.mirrorservice.org/sites/sourceware.org/pub/cygwin/release/...
How do I manually install it in cygwin? It does not seem to be a package-manager file format (like an RPM or a Deb), but is there a tool to install it for me?
FYI, I'm operating behind a corporate firewall that prevents me from viewing the main cygwin site (including the documentation), so please nobody tell me to RTFM - I wish I could!
Thanks
If you need an older version, the Cygwin time machine might help. To use it, I had to invoke setup.exe from the command line, giving it the --no-verify/-X option and it still wouldn't let me downgrade the "cygwin" package itself but at least it is, albeit very slowly, allowing me to install the version I wanted to test as a parallel installation.
If you are using the cygwin package installer to install this package, usually if you select to view the full info and scroll to the package you need you will see some info about the version.
Now if you click on the version number you will see that it changes from the oldest in the repository to the current. If your repository has the version you need then just finish the wizard.
Some cygwin mirrors keep old package files, for example, http://mirror.isoc.org.il/pub/cygwin/
You can use Sonatype nexus to mirror an existing cygwin repository, but provide your own setup.ini .
Copy the already downloaded repo content to c:\progs\nexus\sonatype-work\nexus\storage\mirror.isoc.org.il-pub-cygwin\
Put your own setup.ini and setup.bz2 there.
Start setup.exe with --no-verify
Paste
http://localhost:8081/nexus/content/repositories/mirror.isoc.org.il-pub-cygwin/
into the mirror selection box and click "Add"
