Re: Install Java Windows 7 Ultimate 64 Bit
Harold Yengo
They provide native MSI installers which should be easier to deploy and they include support for setting reg keys the same as Oracle Java for dealing with any apps that explicitly check for these keys during install to verify java is installed.
Yes, this is OpenJDK which is the FOSS version (but still binary compatible with Oracle Java), when you install it make sure you tell it to set the Oracle reg keys (FeatureOracleJavaSoft if you are using commandline options), as most software will check these keys to detect if Java is installed.
Sometimes, attempts to uninstall JDK through the Windows Add/Remove program leave behind some Java entries in the registry that are not fully removed. These left behind registry entries can cause problems in installing a new version of Java. The following are the methods to cleanup registry entries:
To save the registry key before deleting, in the menu bar, select File and then Export. In case you deleted the wrong registry key, you can restore the registry from your saved backup file by selecting from the menu bar File and then Import .
When you install JDK 22 and then install JRE 8, and then run the java -version command, 1.8.0 is displayed in the output instead of 22. This is because the javapath is placed before JDK 22 location in the user environment path.
Questions asking us to recommend or find a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it.
I'd like to install a Java application as a Windows service. I did so successfully a couple of years ago using this Java Service wrapper. Unfortunately, it seems like this tool is not in development anymore and thus no Windows 7 and 64 bit versions are available. I need to install my Java application on Windows 7 and XP machines.
I have recently used Java Service Wrapper from Tanukisoftware and it works perfectly on windows 7. Also the tool is pretty handy as it provides pretty extensive integration mechanism from simple jar execution to shutdown hook functionality as well.
Also windows resource kit includes a tool called servany.exe which i successfully used on Windows Xp to start a jar file as a service by lanuching java.exe with arguments to my jar file, however since windows 7 this somehow does not work.
I have had this problem. I was able to fix it thanks to a co-worker. The problem started happening after I installed HP Unified Functional Testing (UFT, aka QTP). Installing this product changes the Windows environment variables used by Java. He told me the following: "So change the names of JAVA_OPTIONS, IBM_JAVA_OPTIONS, JAVA_TOOL_OPTIONS to something else (both in system and user variables) and delete any Java folder(in Program Files (x86) or Program Files) which gets installed despite the error. Restart the system and then try installing Java."
My answer is not related to win 10, but might help someone who is having similar problem in windows 7 machine and not able to install jre 32 bit version. the work around to this is once you downloaded the jre, copy the path "C:\Program Files (x86)\Java\jre1.8.0_121\bin\javaw.exe" and paste it under java runtime environment settings which is found -Java Control panel>java>view
I had this problem for a month now. I tried everything on my windows 8, but I couldn't get the latest java on it. When I tried to install java on an empty computer, the 64 bit version did not go through (error 1603) and I realized the problem didn't come from an old java install and I install 32 bit. it worked on the new computer with windows 7 and on my computer running 8.1.
I encountered this error on Windows 8.1 and when I checked with Oracle web site, they said that is is not yet resolved, and under investigation. They also showed a link for off-line installation as an alternative arrangement. However, upon investigation of my system, i found out that the available space in C drive was only about 20 MB or so. I cleared my system and provided enough space. When I tried with the extra space, I didn't encounter any error. May be, you could try with a better free space...
First you should close the browser because if any webpage will use Java, it will cause conflict. Then do custom installation, i.e. install in some other folder other than default folder and point environment variable to newly installed Java location. It will resolve your issue.
So I've downloaded jre-6u23-windows-i586.exe and when I try to run it, it causes a page fault and craps out. I can unpack it using 7-zip, but I'm not sure what to do with the contents (just move them around over-top my existing install of JRE 5 update 22?).
Not quite, actually. the JRE's have a major revision number and then an update number. JRE5 is a prior version than JRE6. Then you have to consider update numbers from there. JRE6u22 is an earlier version than JRE6u23.
As I understand it, the major revision number involves how the Runtime handles Java code. If that gets changed, the Java applets become incompatible. As for updates that goes for adding new features, bug fixes, and changes - all that don't break backwards compatibility.
You may be able to get higher versions to work properly with KernelEx, but I will say the last version I have here on my Windows ME disk that I know that works with 98/ME is JRE6U6. You can download prior versions of Java software here:
Here it goes like that with KernelEx installed for the latest java runtimes. I run the executable which seems to autoexit without doing anything. In fact it extracts an msi installer + cab file to a subfolder of C:\Windows\Application Data\Sun\Java named as the version to install. Then I run the msi installer from there and it installs normally. Just installed the newly released update 24 today, no problems.
I tried 8u8 firefox acted like there was nothing at all and told me i need to dl java, i'm trying 6u24 now. even if it doesn't work on FF i'm gonna see if it is good enough to run this java psp emulator.
This tutorial shows you how to write and run Hello World program in Java with Visual Studio Code. It also covers a few advanced features, which you can explore by reading other documents in this section.
To help you set up quickly, you can install the Coding Pack for Java, which includes VS Code, the Java Development Kit (JDK), and essential Java extensions. The Coding Pack can be used as a clean installation, or to update or repair an existing development environment.
Create a folder for your Java program and open the folder with VS Code. Then in VS Code, create a new file and save it with the name Hello.java. When you open that file, the Java Language Server automatically starts loading, and you should see a language status item with a loading icon on the right side of the Status Bar showing the language status is busy. After it finishes loading, you can hover on the language status item and find the loading process has been finished successfully. You can also choose to pin the status item in the status bar.
To run and debug Java code, set a breakpoint, then either press F5 on your keyboard or use the Run > Start Debugging menu item. You can also use the RunDebug CodeLens option in the editor. After the code compiles, you can see all your variables and threads in the Run and Debug view.
So my problem is that I switched from java 8 to java 17 recently (I required java 8 for a course), but I noticed that on ubuntu terminals, java -version still showed openjdk-1.8.(something), rather than jdk-17 or something like that.
So I thought that uninstalling openjdk would do the trick, which I did with sudo apt-get autoremove openjdk-8-jre. However, now typing java in an ubuntu terminal doesn't work anymore at all, and shows: Command 'java' not found, but can be installed with: .... But I fear that installing it with one of these commands will install a new version of java, rather than using the one that's already installed.
There are a few... unique things about WSL that matter here. First, if you type the name of a .exe that is in the Windows side, but from WSL, it will work. For example, open a Bash prompt in WSL, type notepad.exe, and press enter. Notepad will open.
Before you uninstalled OpenJDK 8, you had openjdk-8-jre installed in WSL and Java 17 installed in Windows. When you called java from Windows, it was smart enough to add the .exe, and run the Windows copy of Java. But, when you switched to WSL, when you typed java, it ran the Linux version. But if you typed (into WSL) java.exe, it would have launched the Windows version of Java from WSL for the same reason that Notepad worked.
If I wanted to do Java development from WSL, I would uninstall the Windows version of Java completely, install my desired version of Java in WSL (sudo apt update && sudo apt install openjdk-17-jre), and just do development from in WSL via the WSL Java compiler.
How do I get Gradle to detect available JDKs on Windows? From the documentation there is nothing mentioned of any configuration for Toolchain to work on Windows.
Other that to specify custom toolchain locations
org.gradle.java.installations.paths=C:\Program Files\Java\jdk-11,C:\Program Files\Java\jdk-14,C:\Program Files\Java\jdk-15,C:\Program Files\Java\jdk-16
I just tried to unpack the JDKs under C:\Users\myuser\.gradle/jdks
Running gradlew.bat -q javaToolchains does not list them, but the build does not fail. The toolchain I have defined in build.gradle for JDK-14 is used.
I installed OpenJDK 11, 14, 15 and 16 using the MSI installers.
Checked to update registry for all of them.
Running Gradle with JDK 11. JDK 11 also has the JAVA_HOME.
Gradle now lists all these as toolchains.
