AEM jar not starting

I have an AEM jar file AEM_6.5_Quickstart. I am trying to get it running but facing issues.
First thing is my jar is not identified as normal on my system like other jars, as you can see there is no icon associated with my jar file.
Second is when i double click on it to run it i get the below prompt to choose the program to run it with, which ideally should not appear. I was getting errors when i was running maven command to generate project using zulu jdk so i had installed jdk from oracle website, now that is removed from my system and when i double click on jar file i still get the option to run it using oracle jdk
Third problem which i am facing is that when i run the jar using zulu x64 Architecture as in above image it starts the jar but i get the below error when i go to localhost:4502
i google searched for solutions and found that indexing might be the problem so i deleted the file at crx-quickstart/repository/index after stopping the jar. When i restart it it gets stuck and doesnt start for some reason as in below picture, the progress bar doesnt move even though i waited for hours. I also made sure that sling authenticator service was running.
This is the output in case it helps for the java version being used and the path is setup as C:\Program Files\Zulu\zulu-11\bin. I am unable to fix this issue, any help is much appreciated.

First, delete the whole crx-quickstart directory (since this is a local environment being set up for the first time), and this way you will have a clean start. After that, maybe the .jar extension is missing from the filename, please add it. Finally, it is easier to use a .bat or .sh script (you can customize parameters and runmodes for AEM). But for a first run, quick setup with the default sample content, just try java -jar AEM_6.5_Quickstart.jar

It seems like windows messed up with your java versions, you can go and fix your windows JDK references from the registry, you can do that by pressing win + R then type "regedit", once open look for the next value:
"HKEY_CLASSES_ROOT\jarfile\shell\open\command" then open the "default" value and check that your path is correct, mine for example is :
"C:\Program Files\Java\jdk1.8.0_202\bin\javaw.exe" -jar "%1" %*
use mine as reference only change the first part between quotes for your path to the JDK.
Usually that should fix it, but some times there are some other registry references that ruin your jar files association, if you can open PowerShell/cmd or bash terminal type java -version and get the proper version of your Java installation, another workaround can be opening terminal, navigate in terminal where your jar lives and then type
java -jar yourJarFile.jar

Getting "Error: JAVA_HOME not found in your environment" when attempting to create a new Maven project in VSCode

I'm attempting to generate a Maven project via VSCode's Maven for Java extension.
Here's my issue: After I click "Create new Maven Project" in the Explorer, choose the quickstart option, and choose the folder I want to work in, I am given an error in terminal which reads as follows:
Error: JAVA_HOME not found in your environment.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
Currently, my JAVA_HOME system variable is set as C:\Progra~1\Java\jdk1.8.0_271.
Any suggestions for how to make this error go away? I'm not sure if it matters, but my JDK is installed on my C drive and I am attempting to create a project on my M drive.
Thanks!

1.Add java to PATH:
Control Panel-> System-> Advanced system settings-> Environment
Variables:
Under User variables, Choose Path, click New:
Copy the path of the JDK bin directory.
Open Command Prompt, and run java --version. If there's no error
shown and you get the right jdk information, turn to the next step;
2.Install Java Extension Pack in VS Code;
3.Press Ctrl+Shift+P to open Command Platte and choose Java: Configure Java Runtime:
Turn to Java Tooling Runtime and select your installed jdk, JDK
for Language Server is equivalent to java.home:
Then reload VS Code to make change effective.

The solution to this problem was setting both a user Path variable and a new system variable "JAVA_HOME" specifically to the address of the bin folder of my Java 11 installation.
In my case the path looked like this:
C:\Program Files\AdoptOpenJDK\jdk-11.0.8.10-hotspot\bin
I have a hunch that my issue may have related to the fact that I have two JDKs installed- one for Java 8 and one for Java 11- but I'm not sure.
Thank you to those who helped!

I have manage to configure this entirely through Visual Studio Code. Using the reference for the Maven extension: https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-maven
I set my Java home path in Visual Studio Code, like this (inside of settings.json):
"java.home": "C:\\Program Files\\Java\\jdk-9.0.4"
And then you can enable Maven to use the same path with the settings below:
"maven.terminal.useJavaHome": true

How to set Eclipse Java version in OS X

When I download and expand Eclipse EE version a file of type Application is created :
I'm new to using to Eclipse on MAC. I want to set the java version to
export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
But no eclipse.ini file is created. How to set and or install Eclipse on MAC and set the java version ?

This solution allows you to specify the JVM for a given eclipse installation, without changing any system properties. Make sure you have a valid JVM (usually JDK 8 for eclipse) installed.
Here are the steps:
open finder and navigate to the location of Eclipse (i.e. Applications)
right-click on the eclipse application
select "show package contents"
navigate to /content/Eclipse/eclipse.ini
open the .ini with a text-editor
at the top of the file, add the following lines (or replace the existing -vm line)
-vm
/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/bin
You need to replace adoptopenjdk-8.jdk with the name of your JVM.

File type "Application" is actually a directory. Right-click it (or control click) and select "Show Package Contents". You should find eclipse.ini at Contents/MacOS/eclipse.ini inside the Eclipse application directory.

You need to install the full JDK rather than the JRE before you can use it with Eclipse. The full JDK should set itself as the current Java. The JDK installs in something like /Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home
As mentioned in the other answer the Eclipse application is actually a directory (called Eclipse.app) using 'Show Package Contents' in Finder will show you the contents.

Executable jar not working on other computers

I've created a program using Eclipse and exported as an executable jar (I've tried all 3 library handling options). It runs perfectly on the computer it was written and exported on, but when I try and run it on other machines it does nothing at all. It brings up no errors, nothing at all. I've got several people to try it for my with no luck, and I've tried running it on my laptop (ensuring that Java is the latest version, the same as the machine that it was written on). The MANIFEST file points to the Main class correctly.
Does anyone know how I can solve this issue?
It's incredibly frustrating!
If any more info is needed, I can supply it.

That happened to me a lot of times when I started writing java distributed applications.
Check your project build path (since you're using eclipse, right-button click on your project's folder, then Build Path > Configure Build Path). If any of the paths that are specified there are custom *ie C:\User\daMachineMaster\Java\jre\bin or whatever, it won't work on any other machine because the application will always look for that path, which won't exist in no other machine than daMachineMaster's computer. You could use a wrapper to fix this issue, since it encapsulates all needed information in a .exe, for example.
If that still isn't your issue, search your code for any links to your local directories. For example,
String style = main.screens.ScreenFramework.class.getResource("C:\Users\Dwayne\Music\cool\DarkTheme.css");
After you've located these kinds of hard links, the solution is changing them to be relative links. Check How to define a relative path in java
In the above case, it would mean changing to something like:
String style = main.screens.ScreenFramework.class.getResource("DarkTheme.css").toExternalForm();
Also, as mentioned in other answers, check if the other computers hava java installed. I don't think that they need any environment variables defined to run a runnable jar but if you want to run your app in the cmdline with something like java -jar yourapp.jarthen you need to go to the windows explorer (assuming you're using windows), right-click Computer, then click Advanced System Settings > Environment Variables > New... > Variable Name = JAVA_HOME; Variable Value = directory where java is installed > OK > Click on PATH > Edit... > add JAVA_HOME\bin to PATH > OK

When the Java Runtime Environment (JRE) is not installed, the JAR won't be open and won't show you any message. Try installing JRE into the other computer and try again.

You need to install a Java Runtime Environment (JRE) first, then you can directly run the .jar files on your computer. The Java Development Kit (JDK) download package contains it's corresponding JRE, so that's fine to install too.

Sorry for the late reply. Thanks for all your answers, but it turned out there was an error in my code that simply stopped it running without showing any errors.

I got this problem several times. The issue was the jar file runs on the computer where I have packaged. But in another computer it is not running, some time it shows running if I check the javaw.exe process in cmd but nothing is served.
The solution here is to make sure the following are set correctly.
Make sure the version of java in another computer match the jar file. In some case if you defined java16 in the pom file, make sure the computer has java16 or higher installed and the JAVA_HOME environment is set correct to point to this version.
Make sure the dependent variables are set correctly. For example if the package depends on database driver or database connection consider installing and creating database
For me it worked after changing the java version in the pom file to the oddest ie.the second computer use java 16 then packaged jar file to use java 11.

How to open/run .jar file (double-click not working)?

I can't open or run my .jar file.
I just installed java, but I tried to open the .jar with other programs first, so the double-click defaults to something else and I can't change it back.
java -jar myfile.jar`
Above command returns:
'java' is not recognized as an internal or external command, operable program or batch file.
Is there a way I can still open/run this?
e: OS is Windows 8.
Also, I downloaded the .jar file; didn't create it myself (if that's relevant)
Not sure if it contains an executable (but I think it does).

you can use the command prompt:
javaw.exe -jar yourfile.jar
Hope it works for you.

There are two different types of Java to download: The JDK, which is used to write Java programs, and the RE (runtime environment), which is used to actually run Java programs. Are you sure that you installed the RE instead of the SDK?

Use cmd prompt and type
java -jar exapmple.jar
To run your jar file.
for more information refer to this link it describes how to properly open the jar file.
https://superuser.com/questions/745112/how-do-i-run-a-jar-file-without-installing-java

You may have several JDKs installed in your PC. Some older JDK installers also copy some java files such as java.exe, javaw.exe into C:\Windows\System32 folder.
I had a similar issue, and searched the internet for a solution and none of the suggestions didn’t open by double clicking the .jar file.
In my case the reason is I have multiple JDK & JRE versions installed on my computer. Since I am a software developer working with several different versions for different clients I need to use multiple JDKs in my PC (Windows 10 Pro). So I do not want to change the system variables (i.e. JAVA_HOME, JRE_HOME or PATH), instead I use command prompt to run java in user process whenever I wanted to use a different version.
When installing JDK it registers the .jar file association with latest version we installed in the PC. If you right click on the .jar icon and select properties, it will show that file opens with “Java(TM) Platform SE Binary”. If we look at the registry key: HKEY_CLASSES_ROOT\jarfile\shell\open\command, it will point to latest JDK version.
It is not a good idea (sometimes annoying) to change the registry key every time I want to run an app build from a different version.
So in my situation it is impossible to just double click the .jar file to execute it. But instead I found a work around solution myself.
Scenario:
Multiple JDKs (1.7, 1.8, 9.0, 10.0, 11.0, and 12.0)are installed in the PC, so the latest installed was 12.0.
Problem
Want to double click an executable .jar developed using JDK 1.8 and didn’t work
This is my work around solution:
Create a shortcut for the .jar file that you want to open.
Right click the shortcut icon and select properties -> Shortcut tab
Change the text in the target (for example "D:\Dev\JavaApp1.8.jar")
To
"C:\Program Files\Java\jdk1.8.0\bin\javaw.exe" -jar
"D:\Dev\JavaApp1.8.jar"
Then click ok Double click the shortcut.
It should now open the app.

I was having this same issue for both Windows 8 and Windows Server 2012 configurations.
I had installed the latest version of JDK Java 7 and had set my **JAVA_HOME**system env variable to the jre folder: *C:\Program Files (x86)\Java\jre7*
I also added the bin folder to my **Path** system env variable: *%JAVA_HOME%\bin*
But I was still having problems with double clicking the executable jar files. I found another system env variable OPENDS_JAVA_ARGS that can be used to set the optional properties for javaw.exe. So I added this variable and set it to: -jar
Now I am able to run the executable jar files when double clicking them.

In cmd you can use the following:
c:\your directory\your folder\build>java -jar yourFile.jar
However, you need to create you .jar file on your project if you use Netbeans. How just go to Run ->Clean and Build Project(your project name)
Also make sure you project properties Build->Packing has a yourFile.jar
and check Build JAR after Compiling
check Copy Depentent Libraries
Warning: Make sure your Environmental variables for Java are properly set.
Old way to compile and run a Java File from the command prompt (cmd)
Compiling: c:\>javac Myclass.java
Running: c:\>java com.myPackage.Myclass
I hope this info help.

Go to your java directory,
Copy this path
C:\Program Files\Java\jdk1.8.0_40\bin
Right click on my computer , click properties, then go to "Advanced system settings"
click , Environment variables.
go to "System variables" table, find an entry named "path".
Double click it and go to the end, put a semicolon and paste your path, apply and ok.
It should run now.

first of all, we have to make sure that you have downloaded and installed the JDK.
In order to download it click on the following link
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
(Do not forget to check "Accept License Agreement", before you choose the version you want to download)
For Windows OS 32-Bit (x86) choose "jdk-8u77-windows-i586.exe"
For Windows OS 64-Bit (x64) choose "jdk-8u77-windows-x64.exe"
Install the file that is going to be downloaded. During the installation, pay attention, because you have to keep the installation path.
When you have done so, the last thing to do, is to define two "Environment Variables".
The first "Environmental Variable" name should be:
JAVA_HOME
and its value should be the installation path
(for example: C:\Program Files\Java\jdk1.8.0_77)
The second "Environmental Variable" name should be:
JRE_HOME and its value should be the installation path
(for example C:\Program Files\Java\jre8)
As soon as you have defined the Environment Variables, you can go to command prompt (cdm) and run from every path your preferred "java.exe" commands. Your command line can now recognize your "java.exe" commands.
:)
P.S.: In order to define "Environment Variable", make a right click on "This PC" and select "properties" from the menu. Then the "System" window will appear and you have to click on "Advanced system settings". As a consequence "System properties" window shows. Select the "Advanced" tab and click on "Environment Variables" button. You can now define the aforementioned variables and you're done

You must create a manifest file and specify your class that has the main method. you can build your jar file with manifest file as a parameter.
jar cfm MyJar.jar Manifest.txt MyPackage/*.class
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: Cakes
Build-Jdk: 1.6.0_04
Main-Class: com.foo.App

An easy way to execute .jar files is to create a batch file.
Let's say you placed your jar file on your Desktop;
#echo OFF
java -jar C:\Users\YourName\Desktop\myjar.jar
Copy this code to a .txt file, modify "YourName" and save as "myjar.bat". Then whenever you double click, the jar file will be executed.
Hope this helps.

Short trick: after I only REMOVED SPACES from names of the folders, where the .jar file was, double-clicked worked and the file executed.

In Netbeans please delete current you create the jar file and on the project explore of Netbeans please clean and build 2 or 3 times and right the project folder in project explore and build the jar file.

I had this problem a while back and the solution was really easy.
Just uninstall the current version of Java, download an older one, then uninstall the older and install the latest again.
For example: Java 8 Update 73 current install Java 7 Update 95.
How it works: Java's registry keys were messed up, and when you install the older version they get fixed.

If the intention of the question is to view the contents of the JAR file, then the following java command would help.. (provided, JDK location is added to the environment variables.)
Windows Command prompt> jar tvf yourJarFile.jar
Example:
jar tvf log4j-extras-1.2.17.jar
Reference: http://docs.oracle.com/javase/tutorial/deployment/jar/view.html

I downloaded the latest JDK 7u10. Once you do that, try running your jar, It should execute.
