I'm having a problem of installing java SE runtime 6 on mac, without that, I can't open my eclipse or install Intellij. However, I download the .dmg through an Apple - Java link, but it just doesn't install!
And there's no error message, just the page of falling installation.
I really don't know how to solve it.
This is kind of an update of my problem... I used to have Java SE runtime 6 and tried to install jdk 1.8 and failed. Same picture appeared. Just said failed installing with no error messages. I guessed might be a conflicts? and deleted Java 6 and basically can't run eclipse & Intellij (this solved thought) I still have java 1.7 here.
I just can't figure out why I can't install (or reinstall) java 1.6 or java 1.8. What could be the problem?
Some system updates:
if I do: "which java":
/usr/bin/java
if "echo $JAVA_HOME":
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home
if java -version:
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
What could be possibly wrong?!!!????
God
You need to get Java directly from Oracle (http://www.oracle.com/technetwork/java/javase/downloads/index.html) as Apple stopped supporting Java some time ago. Unless you have pressing reasons for using Java 6 I suggest also installing at least Java 7, although you can have all three versions installed and select the appropriate version for the app you want to run/develop.
Edit Also, if you want to use Eclipse or IntelliJ (go for IntelliJ) you want to get the JDK and not the "runtime" (JRE).

For some reason this issue is to do with with gradle and yarn, no matter what I do to try and get the 'fabric-loom' plugin working, nothing works. It says i am using an outdated version of Java, that i'm on Java 11 (I'm not, I did 'java -version' in the bash terminal), I'm on Mac btw, and it said I'm on Java 16.0.2, which is the version it tells me to be on, I'll attach logs and some code I wrote. If someone could help me, that would be great, thanks in advance :)

Open Command Palette and choose Java: Configure Java Runtime, select jdk16 for both Project JDKs and Java Tooling Runtime.
Then reload window to make change effective and see if the error goes away.
I've always used a Mac and don't remember encountering this in the past so I'm not sure what I'm doing wrong. Theres a bit of q's on this on the internet already but I didn't find a solution yet for me.
I just got a new mac and I'm trying to use rJava & h2o specifically. Below is a couple of things I ran and the output from them. Can someone help me out?
Java --version
java --version java 10.0.1 2018-04-17 Java(TM) SE Runtime Environment

Javac --version
javac 10.0.1
/usr/libexec/java_home -V
Matching Java Virtual Machines (2):

Sys.getenv('JAVA_HOME')
"/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk"
library(h2o)
h2o.init()
H2O is not running yet, starting it now... Error in value[3L] : You have a 32-bit
version of Java. H2O works best with 64-bit Java. Please download the
latest Java SE JDK 7 from the following URL:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
I definitely have the 64 bit of java installed as I re-installed it to be sure and see above the x64 notification from the output. Also, I have gotten this to work on another computer and so I don't understand what is going on with this one.
I also did
vim ~/.bash_profile
EXPORT JAVA_HOME = "/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk"
but this doesn't seem to help me target the Java 8.
You have various problems.
H2O currently does not support Java 10 (that you are using). You need to use Java 8 or Java 7.
Supported versions include: Java 7 or later.
Note: Java 9 is released, but is not currently supported.
Java 9 support will be added in an upcoming version.h2o website
For rJava on Mac I send you to
Loading rJava on Mac OS High Sierra
I am running h2o on a mac with high sierra (and rJava, for a different project) with R v. 3.4.4 and Java 8. All good.
I want to make a python-android-app using this software. I have installed java JDK, when i run java -version i get:
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
However running the line python android.py installsdk from witin rapt directory (as described in the tutorial) tells me that i have no JDK:
I'm compiling a short test program, to see if you have a working JDK
on your system.
I was unable to use javac to compile a test file. If you haven't
installed the Java Development Kit yet, please download it from:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
The JDK is different from the JRE, so it's possible you have Java
without having the JDK. Without a working JDK, I can't continue.
You need to set your jdk to be accesible, and within path / java home :)
Here help from google:
To set JAVA_HOME environment variable, do the following: Launch
Terminal by pressing Ctrl + Alt + T on your keyboard. Depending on
where you installed your Java, you will need to provide the full path.
For this example, I installed Oracle JDK 7 in the
/usr/lib/jvm/java-7-oracle directory.Aug 13, 2012
Trying to install Sencha Command 3.1.1 on my iMac (10.8.3). The installer is saying:
The installer could not find a valid Java(tm) on this machine.
Supported versions: Vendor : Any min. 1.6.0 max. any
Following another Stack Overflow thread, I tried linking /usr/bin/java to /Library/Internet Plugins/JavaAppletPlugin.plugin/Contents/Home/bin/java. Now, I get this on the command line:
~ 🍔 java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
So that looks good, but the installer still complains that it cannot find Java. Why can't it?
What eventually fixed this for me, after consulting with Sencha support, was installing the full JDK rather than just the JRE. I don't know exactly why this fixed it, or what the root cause was, but now Command installed successfully and is working fine.
I had JDK installed, but one thing worked for me was exporting $java_home/bin:
export PATH=$JAVA_HOME/bin:$PATH
This question already has an answer here:
Installed Java 7, but interminal still Java 6 [closed]

Closed 9 years ago.
Ok, I went through the steps to install Java 7 on my Macbook from http://java.com and the applet the FAQ has me run after the install to verify the version running indicates 1.7.0_17 should be what I'm running. The java console indicates the same however, it looks like both are just showing me what version of plug-in is running. When I run:
jave -version
From the terminal it is still showing 1.6.
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)
When I check the JavaVirtualMachines folder it only shows 1.6 and a find from root does not show 1.7 anywhere. I'm obviously new to os x and need some guidance as to what I am missing. I need to install the 7 jdk and set it as my default for all new dev.
Thank you!
Fixed. java.com is the WRONG place to get the JDK. (I should've noticed it!) Go here instead.
