I want to install Carrot2 workbench in file "carrot2-workbench-win32.win32.x86_64-3.10.1" but it always displays "This app can't run on this pc". I've searched for the new workbench by downloading "carrot2-release-3.13.0" but the new workbench doesn't exist.
I use windows 8, 32 bit OS. I don't know if my Java bit is same with my bit OS, so how to check JRE bit (java runtime environment)?
And how to solve this installation problem?
type
java -version
in command to check your java version

I'm a bit confused now. When I run the command java --version in the terminal i get: java 13.0.1. When I open the system preferences and click the java app and then about, i see it says Java version 8 1.8.0_231
Does that mean I have 8, 13 or both?
When I check through the java app.
When I check through the terminal.
When i check for all JDK installed on my system (only 1 version pop ups).
You can have multiple JDK installed in one machine but you can have only one version set as default Java SDK. Looks like you have Java 13 set as default.
Try running the following :
echo $JAVA_HOME
You can also go to the tab Java and see the list of all Java Runtime Environments (JRE.)
Please note that just because you have multiple JREs available doesnot mean all corresponding SDK are also there.
You can have many version of java on your Mac. But you can run only one of this in a process.
On my Mac, system preferences run with java path :
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
But in terminal, this run with java path:
/usr/bin/java
I think you can replace java file in /usr/bin by another version java you want.
that means you jdk version is 13 , and your jre version is 1.8.
jre is used for running java apps ,and the jdk(java development kit) is for building apps with java language. java jdk is like the android sdk
Launching the Eclipse mac installer 64 bit (Eclipse Installer.app downloaded from http://www.eclipse.org/downloads/index-developer.php?oxygen) on Mac OS Sierra 10.12.3 fails and displays the alert message :
The JVM shared library "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/../lib/server/libjvm.dylib"
does not contain the JNI_CreateJavaVM symbol.
My System Preference panel tells me that I have the recommended version of Java (Java 8 update 121).
I tried different things as suggested on different posts (including Eclipse won't start after installing Mac OS X Yosemite (Mac OS 10.10)) :
I made sure to use the 64 bits version
I tried to go back to Java 6 (downloaded from Apple website) but then I get a message telling that I need the latest version of Java (Java 8) to install Eclipse
I tried older versions of Eclipse (Mars, etc.) but the installer returns the same alert message
I tried to re-install Java after editing SystemVersion.plist as suggested here but got the same message.
I installed Java from the jdk8 website and JDK from the oracle website (as suggested by greg-449) but still the same alert message.
Thanks for your help.
I solved the problem by editing the file Contents/Info.plist stored within the Eclipse Installer.app (that you can actually open as a standard folder).
I uncomented this line specifying the vm location
<string>-vm</string><string>/Library/Java/JavaVirtualMachines/1.8.0.jdk/Contents/Home/bin/java</string>
and I replaced the name of the jdk folder by the one I actually have in my /Library/Java/JavaVirtualMachines. In my case, 1.8.0.jdk had to be replaced by jdk1.8.0_121.jdk.
Install the Java 8 JDK not just the JRE. On macOS the JRE does not provide a complete Java installation.
The current (Java 8 update 121) location for the JDK download is here. You should end up with a jdk-8u121-macosx-x64.dmg file to install. Once installed start the Terminal app and make sure that java -version works.
The following was added in the whatever.app/Contents/Info.plist
<key>Eclipse</key>
<array>
<string>-vm</string
<string>/Users/<yourHomeDir>/.sdkman/candidates/java/11.0.2-open/bin/java</string>
<string>-keyring</string>
<string>~/.eclipse_keyring</string>
</array>
Note that, I experienced this issue while using Eclipse Mat and JDK Mission Control
On Mac OS v11.6 (Big Sur ) ,the dependency was Java 11 .
I have 64 bit window 7 ,
I have installed java 6 and java 7 (jdk and jre) in program files(86)
and jre 7 in program files.
I cannot open eclipse, what would I do to start it?
In 64 bit Windows -
program files(86) -> contains the 32 bit programs installed into your
system.
program files -> contains the 64 bit programs or default installed into
your system
What you need is 64 bit jdk, download it from here - Link
exe - jdk-7u60-windows-x64.exe
^^^^^
Looks like you're using 64bit version of Java and a 32 bit version of Eclipse. It's trying to find a 32bit Java version (or vice versa) and that's why it tells you that you need at least Java 1.5.. Try switching to a 64bit Eclipse and also check if your environment variables are set properly, especially %JAVA_HOME%.. You can do a quick check if you're using the correct Java version by running the command
java -version
from the command line.
Right after upgrading to Mac OS Yosemite (10.10), my Eclipse won't start anymore. Instead I get
The JVM shared library /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/bin/../jre/lib/server/libjvm.dylib" does not contain the JNI_CreateJavaVM symbol.
I checked java -version and get
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
I search and have found one similar problem Reinstalling Java 7 JDK on OSX. It is suggesting a reinstallation of Java. I am not sure if my problem falls into the same category as his. So, is reinstallation a good way to solve the problem? Any other advice? Thanks!
Go to the link below and download Java for OS X 2014-001
http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
Hopefully after installing it , it will work
Try this https://jdk8.java.net/download.html Java8u20 early Update.
You may change the system version temporarily in the "SystemVersion.plist" located at System > Library > CoreServices.
Edit as root changing ProductVersion to 10.7.3 (or whatever works for you).
Install java.
Don't forget to change it back.
I solved this issue creating those empties folders as root without downgrade using java8 (vers.1.8.0_60-ea):
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk and
/System/Library/Java/Support/Deploy.bundle
Hope it helps...
I installed Java JRE from Oracle: http://download.oracle.com/otn-pub/java/jdk/8u25-b17/jre-8u25-macosx-x64.dmg
Then install the Apple Package: http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
I was able to install eclipse-ide from homebrew cask
brew cask install eclipse-ide eclipse-java
(Please be aware that brew cask installs to ~/Applications not /Applications)
I don't normally use Eclipse, however I was able to get the IDE up and going. I will note that java on the command line is broken, which is new in Yosimite.
Please let me know if that doesn't work. Or if you need some help with Homebrew or Cask
Make sure you are using the 64 bit version of Mac Eclipse I just tried it works flawless
Two cases:
if you already have installed Java 8 and Eclipse Luna e.g. on Mavericks and (intent to) update to Yosemite: just update, it will work fine.
if you do not have Java installed and want to run Eclipse on Yosemite:
install Apple Java 6 files from http://support.apple.com/kb/DL1572
use an Eclipse Version that runs with Java 6, e.g. Kepler from https://www.eclipse.org/downloads/packages/release/Kepler/SR2
That means, if you want to use Eclipse Luna and Java 8, install it while running Mavericks, then update to Yosemite. Do not try to install Java 8 on Yosemite as that at the moment won't work.
What does not work on my Mac is: installing Java 6 and run Eclipse Luna as that needs Java 7 or 8. Installing Java 7 or 8 does not solve the prob as something with the installer seems to be buggy. Should be solved by Oracle in a few days, however.
After upgrading to yosemite, java 6 jdk is no longer available, remember that jdk 6 for mac osx is a 32-bit application, older eclipse releases needs a 32-bit jvm in order to run properly, a 32-bit application cannot run with a 64-bit jvm like java 7 or 8, so you need to install jdk 6 to run those java applications that needs a 32 bit virtual machine. As already posted here you can download jdk 6 from http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
Tried googling but couldn't found the solution.
Using Windows 7 Ultimate 64 bits.
I have java(64 bits) installed here : C:\Program Files (x86)\Java\jre7
Downloaded Android SDK from here Get the Android SDK
I downloaded the 64 bits considering my windows is 64 bits. Was 32 bits required?
Now whenever i run eclipse.exe I get the following error:
A Java Runtime Environment or JDK must be available in order to run Eclipsec. No java virtual machine was found after searching the following location:
C:\Users..\Downloads\adt-bundle-windows=x86_64-3013131030\adt-bundle-windows-x86_64-20131030\eclipse\jre\bin\java.exe
Sorry can't post a screenshot because don't have any reputation as of now here.
So what should I do?
Do I need to install 32 bit Java or download 32 bit SDK ?
PS: Before running Eclipse I have run "SDK Manager" and it installed some necessary tools. Maybe if this helps.
Just Set your environment variable. Goto to Computer properties -> Advance System Setting -> Environment variables -> System Variables -> path and after a semi colon paste the path of your JRE like this C:\Program Files\Java\jre7\bin click on ok.
Open CMD and type java if this command works properly means your path has been set now. just open you eclipse and it will work this time. You can do this through command line too just type set PATH=C:\Program Files\Java\jre1.6.0_03\bin and press enter.
If still it is not working just paste this set PATH=C:\Program Files\Java\jre1.6.0_03\bin in your eclipse.ini file :)
You have a 32-bit Java. "Program Files (x86)" is for 32-bit programs on a 64-bit system. Either install a 64-bit Java and use the download you have, or get the 32-bit download.
You need to use any of the following configurations:
x64 System, x64 JDK, x64 ADT Bundle
x64 System, x86 JDK, x86 ADT Bundle
x86 System, x86 JDK, and ADT Bundle
