Eclipse is not working properly - eclipse

I clicked on eclipse and I got this error:
Failed to load JNI Library "C:\Program Files (x86)\Java\jre7\bin\client\jvm.dll"
The java version is up to date and the path is correct. I'm not sure how to fix this. I'm using Eclipse IDE Java Developer

I think you may not have downloaded and installed JNI(Java Native Interface). by the looks of it you have the JRE(Java Runtime Environment) and that's where the path is set. Try downloading Java Native Interface and set path to that. Just an idea

Check whether your eclipse and java are of the same version i.e both 32bit or both 64 bit.
You can try on the command line:
java -d64 -version
If it's not a 64-bit version, you'll get a message that looks like:
This Java instance does not support a 64-bit JVM. Please install the desired version.
To check eclipse :
Open eclipse.ini file and observe the following 4th line
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
This shows eclipse is 32 bit

how to change the config file for correct java location to run scala ide - 'returned exit code 1'

I downloaded scala ide, but it won't run.
It gives me this error:
but my java location is C:/jdk.
I do have JAVA_HOME installed and pointing to C:/jdk.
how to make eclipse look to the right location for scala eclipse ide to run?
You have a 64 bit Eclipse (x86_64) that does not work with the 32 bit Java (Program Files (x86)) you have.
To run that Eclipse you need a 64 bit Java, which can be specified in the eclipse.ini.
alright, after soooo much struggle I found a solution - i made eclipse launch with this trick.
#howgler - from the previous comment gave me link to Adopt open jdk
I never heard of it before, but it's just another opensource jdk\jre build.
I selected windows x64
installed the openJDK.
changed the JAVA_HOME env var to C:\openjdk\jdk8025209hotspot - no spaces.
reload the computer
No need to mess with eclipse.ini file, i just deleted all that "-vm stuff" and made it work with adopt_open_jdk

version 1.7 of the jvm is not suitable for this product. version 1.8 greater is required for eclipse nano in window

I am trying to launch Eclipse Nano in Windows 7, but getting the error:
Version 1.7 of the JVM is not suitable for this product. version 1.8 greater is required for Eclipse Nano in Windows
I already have Java 8 installed on the system
Simply download 1.8 JDK from Java SE Development Kit 8 Downloads install it, then copy the jre folder & paste it in:
"C:\Program Files (x86)\EclipseNeon\"
Then rename the folder to "jre", start the eclipse again it should work.
sudo /usr/sbin/update-alternatives --config java
and select the jvm 1.8
I faced the same issue (Windows 10). You need to set the "JAVA_HOME" system environment variable to point to JDK 8 folder and edit the "Path" system environment variable to have a new path to JRE 8's bin folder, this should be at the top of the list.
I too got the same error while installing
Possible reason for the error - The eclipse version, you are installing and the Java version should be of same bit, i.e. either 32 bit or 64 bit
Solution: I have downloaded both the java for 64 bit and 32 bit and installed, now my problem is gone.
Please let me know if it works for you.
When you download the latest eclipse, and extract it, you can find the folder named eclipse-installer with eclipse-inst file inside it. Instead of double-clicking it to start installation, just navigate to the folder in terminal and run ./eclipse-inst command. It does the entire installation for you. It worked for me and hope who also got the same problem(version 1.7 of the jvm is not suitable for this product. version 1.8 greater is required) gets solved. :)
On a Windows system I had the same problem.
Although I had only Java 1.8 installed, I found that I also had a 1.7 upgrade file installed too (which didn't get uninstalled automatically when I installed 1.8).
Uninstalling this upgrade file allowed me to install Eclipse IDE.
I had the same issue and I had a different solution to this problem.
Though I set the JAVA_HOME to 1.8 (Both through CMD and environment variables), the error was persisting.
So I opened CMD prompt, typed:
java - version
to find out 1.7 was the version my system was set to. Until then I had no clue from where it was fetching this version.
And then I changed it to 1.8 using this command:
set path=C:\.....eclipse\jdk1.8.0_141-b15\bin
AND IT WORKED!
Recheck if it is set to 1.8 with the same command:
java -version
You should be good to go now!
if it's a 64-bit Eclipse. You'll need to explicitly download and install the 64-bit Java 8 or later.
download it from here
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
tips for windows users
Version 1.7 of the JVM is not suitable for this product. version 1.8
greater is required
user get above error message because they had multiple jdk version or they do not have latest version of jdk installed , even if you install latest version of jdk and you if you have not removed old version of jdk like 1.7 you will get the above error message , so better to get rid of old version of jdk and jre etc.
-> ignore this step if you have insallted latest version of jdk already
download 32 or 64 bit latest jdk from : https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
-> go to C:\Program Files\Java and look for old version of jdk , let say if you have 1.7 versions of jdk delete them so that you are left only with latest version , you can remove old versions of jre too here just by deleting.
-> next run eclipse you will not get v1.7 message
Find the JVM
If a JVM is installed in the eclipse/jre directory, Eclipse will use it; otherwise the launcher will consult the eclipse.ini file and the system path variable. Eclipse DOES NOT consult the JAVA_HOME environment variable.
To explicitly specify a JVM of your choice, you can use the -vm command line argument:
eclipse -vm c:\jre\bin\javaw.exe ''start Java by executing the specified java executable
eclipse -vm c:\jre\bin\client\jvm.dll ''start Java by loading the jvm in the eclipse process
Go to Eclipse directory, find and open eclipse.ini configuration file then modify below parameter to your desired version, it will work.
-Dosgi.requiredJavaVersion=1.8
It worked for me
Eclipse will consider the version that is mentioned in eclipse.ini file, this error
means that your installed java version (in environment variable) and the mentioned java
version in eclipse.ini file is not matching.
You may just change the java version there (it will be in eclipse-installation-dir).
Change the property as below:-
-Dosgi.requiredJavaVersion=
Updating below line in eclipse.ini worked for me
-Dosgi.requiredJavaVersion=1.8
Two things:
Check this question here as it's similar and has some good pointers Eclipse - no Java (JRE) / (JDK) ... no virtual machine
Also, get the latest JRE and JDK from Oracle vs from java.com http://www.oracle.com/technetwork/java/javase/downloads/index.html
Today I meet the same question. I download the file that named "eclipse-inst-linux64.tar.gz". When I open the eclipse, it shows "Version 1.7.0_121 of the JVM is not suitable for this product. Version: 1.8".Then execute
cd /usr/bin/
sudo ln -s /Your_JAVA_PATH /usr/bin/java
Then you can install eclipse.
Make sure java and eclipse versions are same(32bit or 64bit)
Try running eclipse-installer as administrator(this worked for me)
If you need to skip this step just simply change Required Version number, ex:
open with any text editor instalation path/AptanaStudio3.ini
and change
-Dosgi.requiredJavaVersion=1.8 to -Dosgi.requiredJavaVersion=1.7
This is just for skipping this step.
I had both 1.7 and 1.8 in path and 1.7 was on top and 1.8 below in Pah, so i moved 1.7 below 1.8, thats it it worked.
Go to Oracle's website and download the newest version of Java JDK. (https://www.oracle.com/java/technologies/javase-downloads.html)
Install the program on your computer.
Remove all old environment variables related to Oracle and Java.
Set the environment variables related to the new installation all the way to the bin folder. (include the bin folder in the environment variables section)

QML Preview compatibility check failed. QML preview is disabled

I am on Mac 10.8.2, i have both java 1.6 (32/64bit enabled) and java 1.7 on my machine and the JAVA_HOME is pointed to java 1.6, but whenever I try to enable QML previewing in my momentics ide (QNX® Momentics® IDE for BlackBerry® 10 Native SDK, Version: 10.0.9), I get the error in the Title. looked a bit into the log under workspace/.metadata/.log, and it logged the following:
!MESSAGE QML Preview compatibility check log.
Error: This Java instance does not support a 32-bit JVM.
How can I get the ide to point to java 1.6? Is it somewhere in the startup script of the application that I can change?
Thanks
QNX Momentics is based on Eclipse, so you should be able to change the JVM used by editing the .ini file for the IDE. If your Momentics is installed in the default location, in Finder navigate to:
/Applications/bbndk/ide/macosx/x86/eclipse/
Right click on qde.app (if you have extension hidden it might just be qde with the momentics icon) and choose Show Package Contents.
Under /Contents/MacOS/ edit the qde.ini file in TextEdit.
At the top of the file, before -vmargs add the following:
-vm
/path/to/your/java/jvm/here
ie.
-vm
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java
Save the file and launch Momentics, and it should now be using the JVM you specified. Check your workspace/.metadata/.log after the startup to confirm this.
I've met the same problem with you, I've tried #nonesuchnick 's answer but unfortunately that did not work for me.
And I've similar environment with you: I've got Java 1.7 (the Oracle one) and 1.6 (the Apple one) installed on my Mac (10.8.2).
I resolved my problem via this way:
Delete Java 1.7 completely
Check your NDK installer's md5 to ensure you've got the correct one.
To delete Java 1.7 completely, you'll need to delete the jdk1.7 folder under
/Library/Java/JavaVirtualMachines/
and delete the internet plugin JavaAppletPlugin.plugin under
/Library/Internet Plug-Ins
Then open terminal and type java -version to make sure that your PATH variables is correctly set to your java 1.6 path (I mean the Apple one).
Upon finish this, you can try to uninstall the BB10 NDK and reinstall it, then try to enable the QML Preview, this time it should work.

Eclipse JRE or JDK missing

I am trying to use Eclipse on a friends computer but we keep getting this when we run Eclipse
We have the environmental variable set as well.
Edit
it was working before he installed the black berry plug in.
The variable JAVA_HOME is not required by Eclipse. If your Java installation does not put the Java executables in the PATH, you should add those manually.
A faster way to have your Eclipse up and running consists in modifying the eclipse.ini and using the -vm option.
http://wiki.eclipse.org/Eclipse.ini#-vm_value:_Windows_Example
I had the same problem. For me, I needed the JDK. So I had to install the JDK. It should match the build platform that is, 64bit vs. 32bit windows. After that, I removed, the -vm line from the eclipse.ini file (the suggested fix). It was giving me the "Can't create virtual machine" error. The current release of JDK is version, 7 whereas the Android Developers Toolkit version of eclipse is currently based on JDK 6. But it seems to work. Eclipse came up and is functional. Haven't actually written a program yet.
Go to eclipse folder (where eclipse is installed) and open eclipse.ini file in your editor and add the following code after openFile tag.
-vm C:\Program Files\JDK6\bin\javaw.exe
That's all.
I had a similar problem, since our Java and JDK is consistently updated by our service desk, including uninstalling old JDKs. They take care of the PATH for us, but then the JRE that Eclipse was used to "seeing" was gone. So, the thing that has worked best for me is to modify the shortcut's "target" from:
"C:\Program Files\Eclipse\Eclipse IDE for Java EE Developers\eclipse.exe"
to
"C:\Program Files\Eclipse\Eclipse IDE for Java EE Developers\eclipse.exe" -vm "C:\Program Files\Java\<jdkver>\jre\bin\javaw.exe"
That will point Eclipse toward to the JRE in the JDK you want it to use, and then you can update that shortcut when your JDK updates.
This is on Windows 64bit, obviously.
It can also happen on mismatch of JAVA and Eclipse bit version.
for eg:
If in your System java is 32 bit and you are trying to install Eclipse of 64 bit then the same situation might occur.
Because Eclipse will look Java in Program Files while at the same time Java may be present in Program Files (x86).
So in this case eclipse will not get java and throw the same error.
While installing eclipse, Jre missing :
I solved my error as follows:-
This error may comes if you have 2 program files folder in your system.
"Program files" &
"Program files x86".
Please install JDK&JRE in the "Program files" folder.
Hope your jre missing error get solved.
this works for me:
open eclipse.ini file in your editor and add the line: -vm C:\Program Files\JDK11\bin\javaw.exe
update system PATH with correct JDK path.

Eclipse linking JDK

I have extracted Eclipse on my C partition. I got windows 7 64 bits. Eclipse is 64 bits. But JDK is 32 bit. Once I run eclipse the pop menu is saying it can't find JDK or JRE on some sort of path. Once I run Eclipse from USB drive it works fine. What is the problem? Should I specify envorinmont variables, set classpath or something? What exactly should I do?
Best regards
Why don't you get the 64bit JDK?
Did you download any java jdk on your pc? To check, open a command prompt and launch the command java -version then javac -version If one of them fails, you need to download java jdk from oracle's website
1. If you are using windows then i will recommend you to download Windows x86 jdk-7u5-windows-i586.exe.
2. Install it... in C:\Program Files\Java\
3. Include this in your System PATH C:\Program Files\Java\jdk1.7.0_05\bin .
3. Then type java -version in your command prompt, and if you get the version of your JDK then, you have properly installed the java, and your path is properly configured.
4. Extract your Eclipse folder from the Eclipse.rar downloaded from Eclipse site.
5. You can place this Extracted Eclipse folder anywhere in the disk, but i recommend you to store it in c: drive as this C:\Program Files\eclipse
6. Now i think it should work.............
In a command prompt, a java -version should show the details of the installed JVM.
For example, a jdk7 32-bit version would show this:
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) Client VM (build 23.1-b03, mixed mode, sharing)
A jdk7 64-bit version would show this:
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)
However, the standard JDK installation copies the java.exe and javaw.exe on the c:\Windows\System32 folder, which could be the ones that Eclipse looks for. This could get really messy if you've tried to re-install different JDK versions and you loose track of the last one you installed (or like me, if you install different versions for backwards support on some legacy projects).
To be 100% sure of the JVM used by your Eclipse, just modify the eclipse.ini file located in your eclipse/ folder so it points to the exact JVM you want. For example, add these lines if you want to use your jdk7 64-bit (check if the same folder applies):
-vm
C:\Program Files\Java\jdk1.7.0_05\bin\javaw.exe
Start Eclipse, and it should work fine.
Go to this site fore more info on the eclipse.ini configuration.
this tutorial is the only thing that worked for me with Win 64 bit.
Summary:
install
32 bit eclipse
32 bit JDK (NOT JRE)
32 bit Android SDK
Add Java to your PATH environmental variable
open eclipse.ini and add a line pointing to the JDK
I uninstalled all versions of Java from my system first.
