I'm on clean install Windows 8.1 and I'm trying to run the java 8 example applets provided by oracle.
I've:
Downloaded jdk8 x64 (which installed the jre8 also)
Tried to run the applets, but then had to follow the link to install the latest plugin (java7u60) ( I didn't install the 7u60 jre, just the recommended plugin).
It is verified on the java verification page
I now have JDK 8, Java 8, and Java 7u60 as installed programs. Which I think is what is causing the problem.
Tried again and got them blocked by security settings
Went to control panel>java control panel and changed to medium setting
Tried again and got block by security settings again, they are being reverted as soon as I try to run an applet.
Found https://www.java.com/en/download/help/javacpl.xml and tried it, but they still revert when I try to run an applet.
Tried to run jre8/bin/javacp.exe directly as administrator, didn't help either.
Any help on what my next step is? I can't find a java 8 plugin for chrome or firefox so how are they suppose to run the example java 8 applets without it?
Thanks

I have working to setup an project on local. I have used Virtual Box because VMWare Fusion is available for MAC and I am working on windows. During the process when I run “vagrant up --provider=virtualbox” commend then JDK 7 error was displayed error screenshot is given below
http://prntscr.com/m7jp7e
After that I have installed “Oracle JDK 8” on /usr/lib/jvm/ path manually on virtual box Linux and then run vagrant up command then again JDK 8 issue is displayed.
I have also changed the path of java_home and jdk_version in “coldfusion-server.rb” file.
Please have a look error screenshot below.

Mac user here! Highly recommend using CommandBox to run any version of Adobe ColdFusion on a Mac. Much easier to deal with than VirtualBox or manual installation. The only issues you might encounter is with older versions of ACF that run on JRun showing errors in CF Admin related to JRun specific references. Nothing to really worry about.
You can change the JDK and other settings used by CommendBox using server.json:
{
"name":"ACF Application",
"jvm":{
"javaHome":"/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home",
"heapSize":2048,
"minHeapSize":1024,
"args":"-XX:MaxPermSize=1024m"
},
"app":{
"cfengine":"adobe#9.0.2+282541",
"serverHomeDirectory":"serverHome"
}
}
These are some of the settings I have to run a legacy ACF 9 on my Mac using an older JDK with non-default memory settings. See Configuring Your Server for more info.
I am trying to install JBoss Developer Studio 9 on Windows using executable JAR file.
I have Java in my machine and set the PATH and JAVA_HOME environment variables.
But while launching the jar, I am facing this error:
Java virtual machine launcher couldn't find the main class program will exit
Could some one please help me in resolving this.
Try to use devstudio-10.4.0.GA-installer-eap.jar from here. I tried that.
Not sure what the issue was but for future reference the install docs / guides for Developer Studio 9.1 are located here:
https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Developer_Studio/9.1/html-single/Install_Red_Hat_JBoss_Developer_Studio/index.html#Install_JBoss_Developer_Studio_Stand-alone_and_JBoss_EAP
Instructions may be written for linux users, but the same instructions apply on Windows or OSX once you're in a console.
Note that Java 8 is required for Developer Studio 9 and 10, so if that's not your default JDK (eg., JDK 7 is your default, or is found in your PATH before the entry for JDK 8), the installer likely won't work.
Perhaps that's the problem that was reported here?
Still trying to get Eclipse IDE to work and running into Incompatible JVM error. I followed the steps here: I installed Java 7 but Eclipse keep saying that 1.6 is not suitable for this product
But unfortunately to no effect. Running OSX 10.9.5 and uninstalled the out-of-the-box version of Mac. The new version of Java seems to show up in the System Preferences. Please see attached screen capture. I've even done some of the basics like restart my computer, etc. Maybe there are other modifications I need to make to other files. I'm comfortable with Terminal but new to Eclipse and Java.
I have had the same problem as noted above. I could not get Eclipse to install because of Java incompatibilities. The sequence I followed goes like this:
Upgraded to MAC OS Sierra
Downloaded the Eclipse installer but was prompted that I needed to instal a legacy Java.
Installed Java 1.6
Was unable to install Eclipse and was prompted that I needed Java 1.7 or greater. Downloaded and installed Java 1.8
Ran the terminal code 'java -version' // this will check your jre version. This showed returned Java 1.6 despite the fact that I had upgraded to 1.8. The Java version listed in the Java control panel said 1.8
Tried multiple downloads of eclipse and Java and multiple restarts always with the same result.
Visited the Oracle web page noted above:
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html I could not find the above reference to 8u73 and 8u74 but I did find and option to download 1.8.0_12. I did this. It installed without difficulty, and then I was able to install Eclipse without difficulty.
This took hours of my time. I hope this proves useful.
OK, so I don't really know what the problem was, but I simply fixed it by navigating to here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and installing 8u74 instead of 8u73 which is what I was prompted to do when I would go to "download latest version" in Java. So changing the versions is what did it in the end. Eclipse launched fine, now. Thanks for everyone's help!
edit: Apr 2018- Now is 8u161 and 8u162 (Just need one, I used 8u162 and it worked.)
JRE is a Run-Time Environment for running Java stuffs on your machine. What Eclipse needs is JDK as a Development Kit.
Install the latest JDK (and not JRE) from http://www.oracle.com/technetwork/pt/java/javase/downloads/jdk8-downloads-2133151.html and you should be good on Mac!
Open up terminal and check what java version is currently set in your path variable.
You can do that by typing in your terminal
java -version // this will check your jre version.
javac -version // this will check your compiler version
If this shows incorrect java version but you have installed java 1.8 then you have to set path variable to the newer version of java.
To do that do add the line:
export JAVA_HOME=/path/to/java/jdk1.x
to ~/.bash_profile (same as /Users/username/.bash_profile)
Then do this from the terminal to set the new variable
source ~/.bash_profile
Also what's your eclipse.ini set to ?
-Dosgi.requiredJavaVersion=1.7
EDIT:
Please open up terminal and type
find / -name "java" // This should find all folder named java on your file system.
Also how did you install java in the first place ?
Echoing the answer, above, a full install of the JDK (8u121 at this writing) from here - http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html - did the trick. Updating via the Mac OS Control Panel did not update the profile variable. Installing via the full installer, did. Then Eclipse was happy.
Here are steps:
download 1.8 JDK from this site
install it
copy the jre folder & paste it in "C:\Program Files (x86)\EclipseNeon\"
rename the folder to "jre"
start the eclipse again
It should work.
For some weird reason "Java SE Development Kit 8u151" gives this trouble. Just install, "Java SE Development Kit 8u152" from the following link-
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
It should work then.
I downloaded a VM from the Microsoft "modern.ie" site to test IE10/Windows 7 on my Windows 7 computer (which has a different version of IE for testing sites).
It works fine, but our site requires the Java plugin. So, I go to the site in the VM's copy of IE and download from the Java site, but the install always fails with this dialog:
No idea how to proceed, and nothing at that url about this situation either.
Not sure if you still need help, but for those finding this thread all you have to do is manually download java instead of the installer via here:
https://www.java.com/en/download/manual.jsp
after spending a day reading here and there I decided to ask help as I could not find a solution to my problem.
I have to create a java/swt application embedding a browser with full HTML5 support. That works out of the box on both linux and osx with SWT.NONE browser type (using webkit).
Unfortunatelly I have lot of troubles on windows.
First let me say that I'm using SWT 4.2.x on windows 8 64 bit.
To make SWT browser work with webkit I had to install 32bit JVM and manually point to it (as the -d32 switch on default 64bit JVM says that no 32 bit JVM is installed). ALso installed Safari.
And also I had to use 32bit SWT library. WHen finally I got it run I discovered that Safari for windows does not support drag and drop as experienced and stated here:
http://www.w3schools.com/html/html5_draganddrop.asp
So I decided to switch to mozilla. According to Eclipse/SWT documentation I have downloaded and installed XULRunner 1.8.0.1. I have unzipped it into C:\Program Files (x86)\Mozilla\XULRunner\1.8.0.1\xulrunner and run xulrunner --register-user (and also --register-global)
Finally in my code I added
System.setProperty("org.eclipse.swt.browser.DefaultType", "mozilla");
I have also set a global environment variable "MOZILLA_FIVE_HOME" pointing to the same XULRunner installation dir.
But then, when I run my java program (32bit JRE, 32bit SWT) I get
Exception in thread "main" org.eclipse.swt.SWTError: No more handles [MOZILLA_FIVE_HOME may not point at an embeddable GRE]
How can I fix that?
Thanks in advance!
EDIT:
I was running command prompt not as administrator and xulrunner was not registering. Doing as administrator, worked. However I'm still in trouble: XULRunner 1.9.x seems not to support HTML5. For example element.children is not supported.
I managed installing XULRunner 10.0.2 that seems to have the required support. However as soon as I click into my embedded browser, the application just crashes without printing any error on java output console...
I need to find a solution in order to use either ecent version of mozilla or recent version of webkit on windows
Ok, loading XURLRunner 10.0.2 works. The crashing app was due to a stack overflow error in my js code.
I too am trying to embed XULRunner into my eclipse plug-in, with no luck (currently). I came across your answer here. Just wanted to comment that it is not reasonable that you executed
xulrunner --register-user
nor
xulrunner --register-global
on the XULRunner 10.X since according to this post
https://stackoverflow.com/a/7567781/1743693
the support on installing the XULRunner system-wide was removed (which was a good step IMHO)
Trying to execute the aforementioned commands will result
"Error: couldn't parse application.ini"
As for my problem: I keep running into the runtime error:
Can't load library:
C:\Users\david\.swt\lib\win32\x86_64\swt-xulrunner-win32-4236.dll
C:\Users\david\.swt\lib\win32\x86_64\swt-xulrunner-win32.dll: Can't
load IA 32-bit .dll on a AMD 64-bit platform
And I can't figure out where this is coming from.
I'm running a VirtualBox with Windows 8 64bit
If you can elaborate more on what solved your issue with that - i would really appreciate that.
Thanks.
