When starting eclipse.exe it gives and error message
Failed to create Java Virtual Machine
When I click eclipsec.exe then eclipse starts. What is the difference between eclipse.exe and eclipsec.exe?
Why eclipse.exe is not working now which was working yesterday?
What will be impact if I use eclipsec.exe to start eclipse?
Open eclipse.ini file and
Change the vmargs sizes to
-vmargs
-Xms40m
-Xmx512m
-XX:MaxPermSize=256m
It works on my system.
1.Open folder with Eclipse.exe and find eclipse.ini file
2.Replace -vmargs
by your current real path of javaw.exe:
-vm “c:\Program Files\Java\jdk1.7.0_07\bin\javaw.exe”
3.save .ini file and open eclipse. It will work.. happy coding.
When I click eclipsec.exe then eclipse starts. What is the difference
between eclipse.exe and eclipsec.exe?
from eclipse wiki
You can start Eclipse by running eclipse.exe on Windows or eclipse on
other platforms. This small launcher essentially finds and loads the
JVM. On Windows, the eclipsec.exe console executable can be used for
improved command line behavior.
meaning the eclipse.exe find the JVM for you and starts Eclipse IDE , Where as the eclipsec.exe is console exe where you can tweak how eclipse starts
What will be impact if I use eclipsec.exe to start eclipse. It give
command prompt also.
No impact as such, eclipsec.exe is for windows only
In your eclipse.ini file
Add -vm C:\Program Files\Java\jre7\bin\javaw
below the line -Dosgi.requiredJavaVersion=1.6
And then remove 256m which is below the line --launcher.XXMaxPermSize.
It will work.
Adding following line in .ini solved the same reported issue in my machine.
-vm {path}\javaw.exe
Example: "-vm C:\Program Files\Java\jre7\bin\javaw.exe"
Write like below in .ini file and than it will work properly:
-vm
C:\Java\jdk1.6.0_25\bin\javax.exe
Added above line in eclipse.ini file(on the top) and worked for me. C:\Java\jdk1.6.0_25\bin This path can be changed as per your system.
Hope this will help someone.
Eclipse was running fine yesterday (and has been since I installed it about a year ago). Now all the sudden I'm getting the following error on startup:
"A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
C:\Program Files\eclipse\jre\bin\javaw.exe
javaw.exe in your current PATH"
I have not changed anyhing Eclipse/Java related on my machine but a Windows update was applied to my machine yesterday, so maybe that has something to do with it (but I don't see anything that would affect Java). I've looked at all the other posts about adding something to your PATH or adding the -vm option to the Eclipse ini (couldn't get this to work) or copying the jre folder to eclipse\jre (this worked but doesn't seem like a good long term solution). So I'm really trying to figure out how to get things back to the "default" setup without messing stuff up.
I'm running Windows 7, Eclipse Helios and Java 1.6.0_26.
Two ways to work around this .
Recommended way : In your eclipse.ini file make sure you are
pointing -vm to your jdk installation. More on this here. Make sure to add -vm before the -vmargs section.
Pass in the vm flag from command line. http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F#Find_the_JVM
Note : Eclipse DOES NOT consult the JAVA_HOME environment variable.
Make sure both the Java version and Eclipse are belongs to same architecture.So install 64 bit java for 64 bit eclipse.
eclipse.ini:
--launcher.defaultAction
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize<br/>
256m
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
-vm
C:\Program Files\Java\jdk1.7.0_21\jre\bin\server\jvm.dll<br/>
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.7
That worked for me. It doesnt have to be on the beginning, but surely it cant be at the end of the file.
In my case i had few things missing. I didnt install JDK and JRE of 64 bit while eclipse was of 64 bit version. Once done and JDK\bin path was set in PATH variable eclipse worked fine :)
Open eclipse.ini file besides eclipse.exe
paste
-vm
C:\Program Files\Java\jdk1.7.0_21\jre\bin\server\jvm.dll
//find it if you are having another JDK version.
on first line. And you are good to go.
I had same problem after updating java.
Then I paste
-vm
C:\Program Files\Java\jre6\bin\javaw.exe
to show the path of javaw.exe in eclipse.ini file.
Hope this will help you.
After setting Java Path, if you are not able to open your eclipse do below steps:
Go to your Eclipse Folder where you have extracted your eclipse.
Open Eclipse file in notepad (by default it will open on notepad)
Enter two lines
-vm
C:/Program Files/Java/jdk-11.0.2/bin/javaw.exe
jdk-11.0.2 ,It should be your Java Version, which you will get by the above location.
I had the same problem. I my case it was a program i've install that had destroyed the PATH env variable.
so check your PATH environment variable.
First
check if you have both java 32 and 64 bit install then
Setting Path on Windows
Windows 8
Drag the Mouse pointer to the Right bottom corner of the screen
Click on the Search icon and type: Control Panel
Click on -> Control Panel -> System -> Advanced
Click on Environment Variables, under System Variables, find PATH, and click on it.
In the Edit windows, modify PATH by adding the location of the class to the value for PATH, Or simply make sure that the variable name is in ALL CAPS
If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the class as the value.
Close the window.
Reopen Command prompt window, and run your java code.
Via Puppet ATG installation Centos.
ERROR:
No Java virtual machine could be found from your PATH
SOLUTION:
Declear variable :
$java_home="/opt/oracle/product/java/jdk1.8.0_45/bin"
Add This "{$java_home}" Java Exec
require common, java
Exec {
path => [ "${java_home}", "/usr/bin", "/bin", "/usr/sbin", "${temp_directory}"]
}
On Centos 7 I fixed this problem (after a big yum upgrade) by changing my setting for vm in:
~/eclipse/java-oxygen/eclipse/eclipse.ini
to:
-vm
/etc/alternatives/jre/bin
(which will always point to the latest installed java)
If Eclipse isn't finding your JRE/JDK or finding the wrong version, add the following two lines to the beginning of your eclipse.ini file:
-vm
[your-path-to-java-executable]
Try downloading and installing 32-bit version of Java, and then setting the path :)
Yeah it happend to me right now. Go to Oracle site, and search for Java SDK. Make sure you use the same architeture (x86, x64) of Eclipse.
This happened to me also. And I found the javaw.exe in C:\Windows\System32 got deleted after the windows update. Copied one more time and Eclipse started all fine.
Chek os,eclipse,and java whether it is 32 or 64 bit
you can also copy your JRE folder to eclipse directory and it will work corectly
The problem occurred on my machine due to Java version got updated(66 from 60). Pay special attention to it. As said above would like to add
In this file eclipse.ini, which is available where you have installed eclipse search for the line below -vm example
C:\Program Files\Java\jre1.8.0_66\bin
now try to open this location, in case you are not able to open, that means there is some problem. In my case the version installed was jre1.8.0_60 . So there was a small difference which may not noticeable(66 instead of 60). Update it you will be able to open.
I came across same issue y'day, with PATH etc configured correctly.
It can be opened from command line, just now working by a double click.
And it was working now, by just "Run as administrator" :)
Some time this happens when your Java folder get updated.
Open Eclipse folder and search file eclipse.ini.
Open the eclipse.ini file and check whether jre version is same as jre available in your java folder.
I faced same problem when my jre got changed from jre1.8.0_101 to jre1.8.0_111.
C:\Program Files\Java\jre1.8.0_101\bin
to
C:\Program Files\Java\jre1.8.0_111\bin
In my case the problem was that the path was enclosed in quotation marks ("):
-vm
"C:\Program Files\Java\jdk1.8.0_25\bin"
Removing them fixed the problem:
-vm
C:\Program Files\Java\jdk1.8.0_25\bin
My solution is Include JDK's "bin" Directory in the PATH
To edit the PATH environment variable in Windows 7/8/10:
Launch "Control Panel" ⇒ (Optional) System and Security ⇒ System ⇒ Click "Advanced system settings" on the left pane.
Switch to "Advanced" tab ⇒ Push "Environment Variables" button.
Under "System Variables" (the bottom pane), scroll down to select "Path" ⇒ Click "Edit...".
Copy the JDK bin directory from JAVA folder and paste to "Edit..."
you should change the jdk path in eclipse.ini here:
/Users/you_username/eclipse/jee-photon/Eclipse.app/Contents/Eclipse/eclipse.ini
after you should restart eclipse :)
I have a plugin project. When i debug this as an eclipse application, in the 2nd eclipse that opens, I want to open Project explorer window. As soon as I click on the button to do this, I get java.lang.OutOfMemoryError: PermGen space. I tried changing the PermGen space in the preference, but it did not help. Can any one please suggest a solution.
You should add the -XX:MaxPermSize=256m or 512m to the Window>Preferences>Java>Installed JREs preference page. Edit a JRE and add it to the Default VM arguments tab.
The eclipse native launcher uses the eclipse.ini to add extra permgen arguments to Oracle JVMs, but that information is not used during runtime launching.
What if you try to extend the memory of eclipse when it starts. To do that simply open the .ini file (inside your eclipse folder) and edit the lines that refer to permSize and memory size:
e.g.
-XX:MaxPermSize=500m
-Xms500m
-Xmx2000m
If you don't want to set the permgen size for EVERY launch, you can also add the Parameter to the Debug Configuration.
Run > Debug Configurations
Choose the "Eclpise Application"-Configuration on the right side and choose Arguments in the Tabs.
Add -XX:MaxPermSize=512m to the VM arguments:
-Dosgi.requiredJavaVersion=1.6 -Xms256m -Xmx4g -Dfile.encoding=UTF-8 -XX:MaxPermSize=512m
I have some vmargs that need to be added to a command line launcher of Eclipse, but when I do so, the vmargs that are in the eclipse.ini file are ignored.
For example, if I launch Eclipse like this:
eclipse -vmargs -Dmy.sys.prop=true
Then, Eclipse will launch with the JVM default settings for Xmx, Xms, and permgen space. This means that Eclipse will quickly start thrashing memory and be unusable.
I know that I could copy all entries in eclipse.ini into a command line launcher, but I'd rather not do this (confusing and a pain for users).
How can I get an eclipse launch to respect both eclipse.ini and command line arguments?
skip the -vmargs if you want just system properties to be set.
eg :
and what I get on the eclipse config matches with what I set in eclipse.ini .
I've looked on the web for a while and can't seem to find the setting to increase the memory allocated to OC4J when launching from Eclipse. Does anyone know where the setting is?
Thanks.
You can add memory setting in the OC4J_JVM_ARGS environment variable. For example you could have something like:
OC4J_JVM_ARGS=-Xmx512m
You could add others if you want:
OC4J_JVM_ARGS=-XX:PermSize=256m -XX:MaxPermSize=256m -Xms1024m -Xmx2048m
Now, I never have run OC4J from Eclipse (only standalone), but you could do the same by selecting your Server view, then Open launch configuration and in the Arguments tab add the values to the VM arguments section directly like:
-Xmx512m
or
-XX:PermSize=256m -XX:MaxPermSize=256m -Xms1024m -Xmx2048m
