I'm trying to install Chronix on my hadoop cluster(Raspbian) (http://chronix.io/) so i followed the tutorial (in Quickstart) but when i have to $ java -jar chronix-timeseries-exploration-0.2.jar
I got `ERROR:
Could not find or load main Class de.qaware.chronix.examples.exploration.ui.MainRunner`
So I've read lots of things about this, how to change classpath , ... but the thing is that opposite to all of the people who were asking questions, I don't know where the file is if not in the folder : /home/hduser/chronixShowcase so I don't know where to set the PATH I tried with path at:
/home,
/home/user
/home/user/chronixShowcase
/chronixShowcase/chronix-solr-6.0.1/
/chronixShowcase/chronix-solr-6.0.1/bin
with CLASSPATH=path export CLASSPATH
It may have to be downloaded but this file is not on Github (only this kind: chronix-importer/release/data/qaware-jenkins/20160226/jenkins_jenkins-jolokia_jenkins-jmx_qaware-jenkins_2016.02.27_00.00.00.csv.gz)
Do you have any suggestion to find the main class or export the right PATH or if it comes from elsewhere? I would be really happy if you could help me!
According to the quickstart it looks like you download it from GitHub
wget https://github.com/ChronixDB/chronix.examples/releases/download/0.2/chronix-timeseries-exploration-0.2.jar
From: https://github.com/ChronixDB/chronix.examples/blob/master/chronix-timeseries-exploration/README.md
JavaFX is not included in OpenJDK on Linux. As a result the following error occurs when starting the application with OpenJDK.
Solution
Use Oracle JDK that includes JavaFX
Install the missing JavaFX package for OpenJDK, e.g for Ubuntu:
Try:
sudo apt-get install openjfx
Here's what I did:
Downloaded Apache ZooKeeper 3.4.6 (.tar file), extracted to C:\cygwin\home\user\zookeeper-3.4.6\
Ran ant at the root of the ZooKeeper folder (C:\cygwin\home\user\zookeeper-3.4.6)
Navigated to C:\cygwin\home\user\zookeeper-3.4.6\contrib\ZooInspector\
Ran ant, and I get the following error:
Output:
Buildfile: C:\cygwin\home\Jean\zookeeper-3.4.6\contrib\ZooInspector\build.xml
BUILD FAILED
C:\cygwin\home\user\zookeeper-3.4.6\contrib\ZooInspector\build.xml:19: Cannot find C:\cygwin\home\user\zookeeper-3.4.6\contrib\build-contrib.xml imported from C:\cygwin\home\user\zookeeper-3.4.6\contrib\ZooInspector\build.xml
Total time: 0 seconds
This leaves me with no .cmd or .sh file to execute. How come the build-contrib.xml file isn't there?
Also, I noticed that there seems to be an already-compiled ZooInspector JAR file: zookeeper-3.4.6-ZooInspector.jar. However, attempting to run it with the following command yields failure too:
$ java -cp zookeeper-3.4.6-ZooInspector.jar:lib/* org.apache.zookeeper.inspector.ZooInspector
Error: Could not find or load main class org.apache.zookeeper.inspector.ZooInspector
This is a bit frustrating -- setting up the ZooKeeper server was straightforward but for some reason I just can't figure out how to run this standalone GUI. What am I missing?
For windows:
#echo off
set cp="./*;./lib/*;../../*;../../lib/*"
java -cp %cp% org.apache.zookeeper.inspector.ZooInspector
ZooInspector 3.4.6 (that's bundled with ZooKeeper 3.4.6) doesn't seem to be able to connect to a running ZooKeeper instance on Windows.
Better use zkui:
https://github.com/echoma/zkui/wiki/Download
zooInspector just need 3 libraries and 1 jar to load the main class.
the mainclass lives zookeeper-3.3.0-ZooInspector.jar and it needs jtoaster-1.0.4.jar, zookeeper-3.3.0.jar and finally log4j-1.2.15.jar
After download the tar.gz file from apache servers, you must untar and build with ant. finally copy the zookeeper-3.3.0.jar and log4j-1.2.15.jar to contrib/ZooInspector/lib/. Finally cd to contrib/ZooInspector and launch this command
java -jar zookeeper-3.3.0-ZooInspector.jar -cp lib/*
I met the same issue today, and created a pre-compiled version, which should work on Windows as well. You can find details here:

I have a java program in which a use the GLPK Solver. The error that i receive when i run it on eclipse is the following:
The dynamic link library for GLPK for Java could not beloaded.
Consider using
java -Djava.library.path=
The current value of system property java.library.path is:
/Users/maria/Documents/solver_library/GLPK/w64
I had the same problem on my old windows computer and i solved it doing the following:
1. Adding in the Java Build Path->Libraries the glpk-java.jar file
2.Adding as the Native library location of the above jar the corresponding path (C:\ProgramFiles\solver_library\GLPK\w64
3. adding in the PATH environment variable the above path.
I am doing exactly the same things on my new MAC OS X computer but still receiving the above error. I did with exactly the same way the steps 1 and 2 above and also I modified through the terminal the PATH system variable. This now is:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/maria/Documents/solver_library/GLPK/w64
Could you please tell me if you have any idea of how to solve this? I am a new Mac user so i don't know many things.
Thanks in advance!
Here's what I did to make it work on OS X.
Install glpk.
I used for this homebrew
$ brew install glpk
$ brew install swig // this package we well need for glpk for java
Install glpk for java http://sourceforge.net/projects/glpk-java/files/glpk-java/
Unzip the archive with:
$tar -xzf glpk-java-1.0.37.tar.gz
$cd glpk-java-1.0.37
Configure with:
$./configure \
CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers \
SWIGFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers
Make and install with:
$make
$make check
$make install
Now in swig dir you should have 3 jars:
glpk-java.jar, glpk-java-sources.jar, glpk-java-javadoc.jar and the .lib folder (hidden).
For compiling you need to put glpk-java.jar in your classpath and specify javac option -Djava.library.path=/YOUR_PATH/libglpk-java-1.0.37/swig/.libs
Related to : Executing rake tasks on an exploded war on tomcat without jruby being installed
I'm trying to run rake tasks in my Tomcat server that doesn't have JRuby installed. I'm using warbler to create a war file.
Using the answer to the linked question, I ran:
java -cp lib/jruby-core*.jar:lib/jruby-stdlib*.jar org.jruby.Main -S rake -T
This gets me the error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/jruby/Main
Caused by: java.lang.ClassNotFoundException: org.jruby.Main
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
ls lib gets me:

ojdbc6.jar
Opening up the jruby-core-1.6.8.jar file, I can see that there is indeed a org/jruby/Main.class file.
As one can see from the file listing, there is no jruby-complete jar file, so I can't run the command from https://stackoverflow.com/a/9982556/684934
What am I doing wrong, and is there by now a better way to do this?
I was working on a similar problem 2 months ago, so things may have changed, but I needed to include all the jars in my class path, had to use bin stubs, and had to set GEM_HOME to get everything working. It may have been simpler, but the posts you referenced didn't work for me either.
I actually had jruby installed, (but I was only using it to build the concatenated class path), so my setup was something like:
cd /path/to/application/
export GEM_HOME=/path/to/application/gems
export CLASSPATH=$(jruby -e 'puts Dir["lib/*.jar"].join(":")')
RAILS_ENV=production java -cp $CLASSPATH org.jruby.Main bin/rake -T
Also useful, the jruby-jars gem can be included in your gemfile to set the version of jruby that warbler includes (I was using gem 'jruby-jars', '1.7.0.preview2' as 1.7.0 wasn't released yet)
I want to execute my program without using an IDE.
I've created a jar file and an exectuable jar file. When
I double click the exe jar file, nothing happens, and when I try to use the command in cmd it gives me this:
Error: Unable to access jarfile <path>
I use the command: java -jar Calculator.jar
How I created the jar:
Right click on project folder (Calculator)
Select
Click on Java Folder and select "Exectuable Jar File", then select next
Launch Configuration: Main - Calculator
Create Export Destination
Hit "Finish" and profit! Well, not really.
I had encountered this issue when I had run my Jar file as
java -jar TestJar
instead of
java -jar TestJar.jar
Missing the extension .jar also causes this issue.
Fixed
I just placed it in a different folder and it worked.
[Possibly Windows only]
Beware of spaces in the path, even when your jar is in the current working directory. For example, for me this was failing:
java -jar myjar.jar
I was able to fix this by givng the full, quoted path to the jar:
java -jar "%~dp0\myjar.jar"
Credit goes to this answer for setting me on the right path....
I had this issue under CygWin in Windows. I have read elsewhere that Java does not understand the CygWin paths (/cygdrive/c/some/dir instead of C:\some\dir) - so I used a relative path instead: ../../some/dir/sbt-launch.jar.
I had the same issue when trying to launch the jar file. The path contained a space, so I had to place quotes around. Instead of:
java -jar C:\Path to File\myJar.jar
i had to write
java -jar "C:\Path to File\myJar.jar"
Just came across the same problem trying to make a bad USB...
I tried to run this command in admin cmd
java -jar c:\fw\ducky\duckencode.jar -I c:\fw\ducky\HelloWorld.txt -o c:\fw\ducky\inject.bin
But got this error:
Error: unable to access jarfile c:\fw\ducky\duckencode.jar
Solution
1st step
Right click the jarfile in question. Click properties.
Click the unblock tab in bottom right corner.
The file was blocked, because it was downloaded and not created on my PC.
2nd step
In the cmd I changed the directory to where the jar file is located.
cd C:\fw\ducky\
Then I typed dir and saw the file was named duckencode.jar.jar
So in cmd I changed the original command to reference the file with .jar.jar
java -jar c:\fw\ducky\duckencode.jar.jar -I c:\fw\ducky\HelloWorld.txt -o c:\fw\ducky\inject.bin
That command executed without error messages and the inject.bin I was trying to create was now located in the directory.
Hope this helps.
None of the provided answers worked for me on macOS 11 Big Sur. The problem turned out to be that programs require special permission to access the Desktop, Documents, and Downloads folders, and Java breaks both the exception for directly opened files and the permission request popup.
Fixes:
Move the .jar into a folder that isn’t (and isn’t under) Documents, Desktop, or Downloads.
Manually grant the permission. Go to System Preferences → Security and Privacy → Privacy → Files and Folders → java, and check the appropriate folders.
I had a similar problem and I even tried running my CMD with administrator rights, but it did not solve the problem.
The basic thing is to make sure to change the Directory in cmd to the current directory where your jar file is.
Do the following steps:
Copy jar file to Desktop.
Run CMD
Type command cd desktop
Then type java -jar filename.jar
This should work.
Edit: From JDK-11 onwards ( JEP 330: Launch Single-File Source-Code Programs )
Since Java 11, java command line tool has been able to run a single-file source-code directly. e.g.
java filename.java
If you are using OSX, downloaded files are tagged with a security flag that prevents unsigned applications from running.
to check this you can view extended attributes on the file
$ ls -l#
-rw-r--r--# 1 dave staff 17663235 13 Oct 11:08 server-0.28.2-java8.jar
com.apple.metadata:kMDItemWhereFroms 619
com.apple.quarantine 68
You can then clear the attributes with
xattr -c file.jar
It can also happen if you don't properly supply your list of parameters. Here's what I was doing:
java -jar test#gmail.com testing_subject file.txt test_send_emails.jar
Instead of the correct version:
java -jar test_send_emails.jar test#gmail.com testing_subject file.txt
This worked for me.
cd /path/to/the/jar/
java -jar ./Calculator.jar
For me it happens if you use native Polish chars in foldername that is in the PATH.
So maybe using untypical chars was the reason of the problem.
sometime it happens when you try to (run or create) a .jar file under /libs folder by right click it in android studio. you can select the dropdown in top of android stuio and change it to app. This will work
My particular issue was caused because I was working with directories that involved symbolic links (shortcuts). Consequently, trying java -jar ../../myJar.jar didn't work because I wasn't where I thought I was.
Disregarding relative file paths fixed it right up.
In my case the suggested file name to be used was jarFile*.jar in the command line. The file in the folder was jarFile-1.2.3.jar . So I renamed the file to jarFile. Then I used jarFile.jar instead of jarFile*.jar and then the problem got resolved
It can happen on a windows machine when you have spaces in the names of the folder. The solution would be to enter the path between " ".
For example:
java -jar c:\my folder\x.jar -->
java -jar "c:\my folder\x.jar"
To avoid any permission issues, try to run it as administrator. This worked for me on Win10.
I know this thread is years ago and issue was fixed too. But I hope this would helps someone else in future since I've encountered some similar issues while I tried to install Oracle WebLogic 12c and Oracle OFR in which its installer is in .jar format. For mine case, it was either didn't wrap the JDK directory in quotes or simply typo.
Run Command Prompt as administrator and execute the command in this format. Double check the sentence if there is typo.
"C:\Program Files\Java\jdk1.xxxxx\bin\java" -jar C:\Users\xxx\Downloads\xxx.jar
If it shows something like JRE 1.xxx is not a valid JDK Java Home, make sure the System variables for JAVA_HOME in Environment Variables is pointing to the correct JDK directory. JDK 1.8 or above is recommended (2018).
A useful thread here, you may refer it: Why its showing your JDK c:program files\java\jre7 is not a valid JDK while instaling weblogic server?
For me it happen because i run it with default java version (7) and not with compiled java version (8) used to create this jar.
So i used:
%Java8_64%\bin\java -jar myjar.jar
Instead of java 7 version:
java -jar myjar.jar
I had a similar problem where TextMate or something replaced the double quotes with the unicode double quotes.
Changing my SELENIUM_SERVER_JAR from the unicode double quotes to regular double quotes and that solved my problem.
this is because you are looking for the file in the wrong path
1. look for the path of the folder where you placed the file
2. change the directory cd in cmd use the right path
I use NetBeans and had the same issue. After I ran build and clean project my program was executable. The Java documentation says that the build/clean command is for rebuilding the project from scratch basically and removing any past compiles. I hope this helps. Also, I'd read the documentation. Oracle has NetBeans and Java learning trails. Very helpful. Good luck!
Maybe you have specified the wrong version of your jar.
I finally pasted my jar file into the same folder as my JDK so I didn't have to include the paths. I also had to open the command prompt as an admin.
Right click Command Prompt and "Run as administrator"
Navigate to the directory where you saved your jdk to
In the command prompt type: java.exe -jar <jar file name>.jar
Keep the file in same directory where you are extracting it. That worked for me.
This is permission issue, see if the directory is under your User.
That's why is working in another folder!
Rename the jar file and try
Explanation :
yes, I know there are many answers still I want to add one point here which I faced.
I built the jar and I moved it into the server where I deploy (This is the normal process)
here the file name which I moved already existed in the server, here the file will override obviously right. In this case, I faced this issue.
maybe at the time of overriding there can be a permission copy issue.
Hope this will help someone.
Have you tried to run it under administrator privoleges?
meaning, running the command in "Run As" and then select administrator with proper admin credentials
worked for me
I was trying this:
After giving the file read, write, execute priviledges:
chmod 777 java-repl.jar
alias jr="java -jar $HOME/Dev/java-repl/java-repl.jar"
Unable to access bla bla..., this was on Mac OS though
So I tried this:
alias jr="cd $HOME/Dev/java-repl/ && java -jar java-repl.jar"
This did not work "Unable to access jarfile"
"C:\Program Files\java\jdk-13+33-jre\bin\javaw.exe" -jar "C:\Program Files\Maxim Integrated Products\1-Wire Drivers x64\ OneWireViewer.jar"
This does work
"C:\Program Files\java\jdk-13+33-jre\bin\javaw.exe" -jar "C:\Program Files\Maxim Integrated Products\1-Wire Drivers x64\OneWireViewer.jar"
The difference is the single space in front of OneWireViewer.jar not withstanding that it is surrounded with quotes and even has other spaces.
