Eclipse can't find the JDk or JRE
I have the latest JRE and JDK installed, however when I install Eclipse Classic 4.2 and try to run it, it displays the following message:
I have tried moving the installation to Program Files, as well as to the Java installation folder itself. The former generates no difference other than the path displayed in the message. The latter starts loading Eclipse, to the point that it shows the blue rectanglue loading box, at which point I get a different error message saying it couldn't load a particular.dll file in the Java installation. That said, I don't see why I would have to move the Eclipse files into the Java folder for it to work.
I used to have a working installation of Eclipse some time ago, which I uninstalled. Now I plan to use Eclipse, possibly with PyDev, in order to learn Python.
P.S. I realize this is not exactly a question involving coding, however I know I can't be the only one experiencing this issue. So hopefully others may benefit from seeing the response.
EDIT: The installation is now working. Here are the steps I took:
1) Make sure the JDK and Eclipse installations are both 32-bit or 64-bit, depending on your setup.
2) Add -vm
/absolute/path/to/jre6/bin to the top of the eclipse.ini file
Note: After reinstalling both Eclipse and the JDK, making sure the bit-type matched, step 2 was no longer necessary as Eclipse finally ran normally.
This question was asked before and the answer was very well written so just follow the link and read the answer to this.
Eclipse - no Java (JRE) / (JDK) ... no virtual machine
It worked for me.
As noted above:
Please refer to http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F#Find_the_JVM.
Also make sure that you're using a 64-bit JDK with a 64-bit bundle of Eclipse, and a 32-bit JDK with a 32-bit bundle of Eclipse.
By default, the 32-bit JDK will install into "Program Files (x86)", and a 64-bit JDK will install into "Program Files". Under 64-bit Windows, you can choose to use either 32-bit or 64-bit Eclipse/JDK - but the Eclipse bundle and the JDK must match. (I'd recommend 64-bit, as your OS supports it.)

I'm trying to install Java JDK 16.0.1. When I double-click the install file in the Downloads folder, it prompts me to allow changes, then does absolutely nothing.
I did some digging around in my %appdata% folder to look for crash reports/logs. It turns out every time I double-click the install file, it crashes with:
Exception Code: 0xC0000005
Exception Information: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
I do have Java Runtime Environment 1.8.0_291 installed, but that shouldn't prohibit the JDK installer, should it?
I also do have Java Runtime Environment 1.8.0_241 installed, and can't seem to be able to uninstall it. Could this be the problem? When trying to uninstall it, it looks for jre 1.8.0_241patch.msi, but can't find it. Regardless, this first issue shouldn't be a result of this old JRE install, correct?
I found this on the OpenJDK bug system:
https://bugs.openjdk.java.net/browse/JDK-8202316
for that user it was happening with the JDK 8 installer but the behavior sounds identical to the issue that you're having. In that post the original poster says "Problem solved. JDK 8u162 installer didn't remove all registry values of 8u152."
Now, I don't know why that's an issue; multiple JDKs should be able to peacefully coexist, but it might be worth a shot in your case before going to the length of doing a fresh reinstall of windows:
uninstall the JRE 8 version (your 1.8.0... version)
use tool or manually clean up any leftover java registry keys if necessary
reboot PC
try JDK 16 installer again
If you truly just have a JRE of version 8 and not a full-blown JDK, you could try using the java uninstall tool here:
https://www.java.com/en/download/help/uninstall_java.html
Also, I did find this old page about manually tracking down java registry entries (from 7.0 and older):
https://java.com/en/download/help/manual_regedit.html
Well, hope this helps. Be sure to let us know whether you get it solved, I'm curious to know. Thanks!
I have formatted my Mac due to some storage issues. Before this, I used Eclipse in a proper way. Now i have installed the JDK
Then, i have installed Java
Until now everything seems to be correct but when I open the Eclipse installer...
What can I do to fix this? I need to work with this the soon as possible.
Thanks
Eclipse on macOS will not start with Java 14 installed, this is being tracked in Eclipse bug 561273.
Installing Java 8 as well does not help. You need to remove the Java 14 install. You could use the Java 13.0.2 release instead.
Eclipse have determined that the root cause of this issue is a change in Java 14 which is described in this bug report JDK-8238225. The fix for this should be in Java 14.0.1
Update: Eclipse runs fine with Oracle Java 14.0.1 so the issue has been fixed.
I also asked this question which was closed, that's why I answer what I have found out: Eclipse will not install on Mac OS Catalina 10.15.4, saying the above error message
Failed to create the Java Virtual Machine.
Deinstalling jdk and install an older one wouldn't help on its own because Eclipse is refusing to install in the first place (as mentioned above). What I have done:
i´ve installed an JDK with boost (you can try several, mine worked with Version 13)
I edited the installer:
Download the dmg file
convert the dmg-file with "hdiutil convert /dev/disk3s1 -format UDRW -o devimage"
mount the converted dmg-file with: "hdiutil attach -owners on devimage.dmg -shadow"
Edit the /Volumes/Eclipse/Eclipse.app/Contents/Info.plist: there is a section which is commented and there you can try the jdk version. You have to give the full path to the java executable, for example:
<string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/bin/java</string>
Then my eclipse started from the (already) mounted Eclipse image without complaining
I had the same issue myself a while back. In your Eclipsepedia it provided an example of what the eclipse.ini file looks like when your trying to specify a JVM. So just change the eclipse.ini file and then make sure that you have all of the correct documents in that path to match the example.
Apologies in advance. I know this is a basic question.
I am new to server administration. I am administering a server where the users do Java development.
They have a Java-based application and do development in Eclipse. Eclipse is 32-bit. The OS is 64-bit.
I recently updated the JDK and JRE on the server. I have both the 64-bit and 32-bit of each installed.
Eclipse ran into an error where it couldn't start after I had updated to the new JRE and JDK. So I took some advice online and updated the -vm path in the Eclipse .INI file to point to the new 32-bit JRE path. It now works.
I have two main questions:
Will updating the JRE and JDK EVER cause an issue with development, or as long as they can open up Eclipse and use at least one version of the JRE or JDK, they will be fine? I guess my fear is that they are going to develop in a certain version and the next version will cause issues down the line.
They develop in 32-bit Eclipse (not sure why they chose 32-bit) but their application runs with 64-bit Java (that is where the path points to for that installation). If something is developed in 32-bit Eclipse can it run with 64-bit Java? Side question: is there a certain advantage with developing with 32-bit Eclipse on a 64-bit system or is it personal choice?
Thanks a lot and cheers!
I guess my fear is that they are going to develop in a certain version and the next version will cause issues down the line.
Java 6 and 7 are end of life; Java 8 code should still be run when Java 9+ rolls out. I've not been aware of any backwards compatibility issues in recent years, it's only forward compatibility that doesn't work (running Java 8 compiled libraries with JRE 7).
They develop in 32-bit Eclipse (not sure why they chose 32-bit) but their application runs with 64-bit Java
The IDE and code run in separate processes. There's no harm in using the 64bit JDK with 32bit editor.
Eclipse 32 bits running on 64 bits JVM
Should I use Eclipse 32bits or 64bits on my new machine?
Will updating the JRE and JDK EVER cause an issue with development...
I believe it technically could render what you developed "obsolete" if you're initially using one JDK with some specs and change for another one with specs that are not "compatible" with what you built so far. By specs, I mean the libraries, tools, etc that the JDK contains. But I would say it would be unlikely that such problems occur. It personally never happened to me. I'd like to have someone with more knowledge give more details though and validate what I'm saying or correct me if I'm wrong.
If something is developed in 32-bit Eclipse can it run with 64-bit
Java?
To my knowledge, there are not related things. In my mind, Eclipse is just your IDE and it allows you to build/compile code using specific JDK (32 or 64 bits). As a matter of fact, you don't even need eclipse to build code but you definitely need a JDK: it's the JDK that give you the tools to compile code that "targets" a specific JRE/JVM and Eclipse is using the tools your JDK provide.
So yes, you can use eclipse 32 bits to build code for a 64 bits JRE.

I recently tried running Eclipse on my Windows installation after several months (since I was working primarily on Ubuntu). Naturally, my java installation was outdated and Eclipse reported that it couldn't find a JDK to work with, so I proceeded to update the existing java installation. However, after the most recent version of Java was installed, the installer proceeded to uninstall the previous, outdated version of java (1.7), with my consent. Now, when I try to run Eclipse, this is the error message I get:
It probably has something to do with setting of path variables or previous eclipse settings and the version of eclipse I'm using is from the Android ADT bundle (please do not ask me to switch to Android Studio; I have my reasons).
How do I fix this and get Eclipse up and running?
No need to re-install eclipse, if you read the log you will notice that javaw was told to use java 6, but it is obviously not the java version you are trying to launch with.
Simply change 1.6 to 1.x in $ECLIPSE_HOME/eclipse.ini.
The error sounds you need to install JRE & JDK 1.6.
I work on Mac OS. I have a similar case I have to install JRE & JDK 1.6 since the one coming with the original OS is newer than it needs
I'm trying to run eclipse for java in Windows 7 64bit edition, and when I run the eclipse.exe file, absolutely nothing happens. A ephimeral javaw.exe process is created in the task manager, but as I said, it's just there for a split second, and it disappears, after that NOTHING. I tried compiling a small program with the javac.exe file, and that works all right, but for some reason I cannot run Eclipse.
Any suggestions on what I could be doing wrong. I'm a complete Java noob, it's the first time I try to do this.
These are the files I have, and I downloaded the Windows 64bit version of eclipse.
Thanks!
EDIT
OK, solved. The book I'm using is misleading... it said I should use the javaw.exe file from jdk1.6.0_21, and doing that didn't work. Now I tried with one in jre6, and it ran.
Thanks everyone and sorry for the hassle!
First, check you eclipse.ini (even a space at the end of a line can prevent eclipse from starting)
Second I am surprised to see java* file in your Eclipse distribution.
You shouldn't' have those, and instead refer to the right java (64 bits) in your eclipse.ini.
In both case, see this eclipse.ini as a good example.
Check also the <workspace>/.metadata/.log (error log file).
I just added it there because it was asking for it, supposedly the best way it to put it in the PATH.
If eclipse is "asking for it", that means your current java installation is not part of the PATH. It need to be reference from the eclipse.ini file.
See also FAQ How do I run Eclipse?
In any event, don't copy any java files around.
Used in your eclipse.ini a path like:
-vm
C:/Prog/Java/jdk1.6.0_21/jre/bin/server/jvm.dll
Do you have the 64-bit version of Java? http://www.java.com/en/download/faq/java_win64bit.xml
I experienced relatively little trouble moving to 64-bit java:
Download Eclipse Helios 64-bit version
Download Java 6 SDK 64-bit version
Install both
Run
The issues may arise if you have both 32-bit and 64-bit JDKs in the same machine. If you want to explicitly run Eclipse with one JVM, then you need to specify its full path in eclipse.ini.
e.g.
-vm
C:/Program Files/Java/jdk1.6.0_20/bin/javaw.exe
Where the path points to the 64-bit version.
The other issue I encountered after moving is that the Subclipse plugin by default uses a 32-bit DLL backend and therefore doesn't work. However Subclipse also works with a pure-Java back-end for Eclipse called JavaHL which solved that issue.
I faced similar problem and did not know how to proceed.
I did following things to resolve it.
In eclipse.ini enter the vm argument to which jre you want to use
-vm
C:\Java\jdk1.7\jre\bin\javaw.exe
If you have -Dosgi.requiredJavaVersion=1.7 line in your eclipse
make sure that version is matching the one that is mentione in step 1.
( in my case it was 1.6 and I had to change this value to 1.7)
Launch eclipse.exe from the command line
