I have installed java JDK 7 in my osx. It is installed in /Library/Java/JavaVirtualMachines/ where are 1.6 java version is installed in /System/Library/Java/JavaVirtualMachines. Which is fine in my case, since I only want to use JDK 7 inside intelliJ ide to run javafx. So I added in intelliJ project structure the 1.7 SDK, but none of my import javafx.* work. How can it be ? How can I check that 1.7 SDK is can be resolved by my ide
Specify JDK to be Java 7 in the project settings.

I try to create a Maven project with Eclipse Oxygen EE using JDK 1.8.0 u301 but when i click finish give this
error.
I don't understand how to solve it because I'm not using JDK 9.
I checked if I had more JDK installed but found nothing.
As suggested by #khmarbaise I downloaded the last version of Eclipse EE:
Eclipse JEE 2022-03-R-win32-x86_64
I suppose it was something related to eclipse version and maven version.
I used the same JDK and JRE for both version.
*Due to some project requirements I "have" to use eclipse 4.18 (2020-12) which uses Java 11 by default and is mandatory to start.
But my entire project is/was written in Java 1.7 earlier. Now , in my mac i have both java 1.8 and 11 installed also my eclipse settings are such shown below.
I have made sure removed all java 11 references in my eclipse and made the project and workspace configure to take the 1.8 jdk and run at 1.7 compiler level.*
but when i run ,project -->clean-->build, i run into the JaxB missing in java 11 ( in java 11 JAXB was removed and my project uses jaxB extensively) This is known.
So i am wondering what am i missing that my projects are still building my project with java 11 and not java 1.7 (using jdk 1.8 configured).
Please help.. stuck on this since some days.

Java 11 JaxB error
If Eclipse itself is being run with Java 11, and you have a plug-in installed that has not been properly update to work under Java 11, as it appears, you will need an updated version of that plug-in. Update to the latest "oracle design studio", and if you still see this problem, contact Oracle support.
The latest Eclipse may require Java 11 to run, but it's simple to set up Eclipse projects that use older Java versions. Don't mess with the Java version it uses to start up, as long as that is a proper Java 11 version.
As one commenter mentions, you'll have to have a particular Java distribution configured in "Installed JREs->Execution Environments", and then you'll have to have the project configured to use that Java version symbol, like "JavaSE-1.7".

Installing NetBeans 8.0.2 with JDK 9.0.1
(2 answers)
Closed 3 years ago.
NetBeans does not download and shows me the message shown in the image below, knowing that I installed the jdk 13 and included in the environment variables correctly
Based on the icon in the top left corner of your screenshot, it looks like you are trying to install NetBeans version 8.x using JDK 13. That is an invalid combination since NetBeans 8.x only supports the use of Java 7 or Java 8.
From the NetBeans IDE 8.0.2 Installation Instructions:
The Java SE Development Kit (JDK) 7 Update 10 (or later) or JDK 8 is
required to install NetBeans IDE.
So unfortunately that error message is more than misleading; it is incorrect. Using releases newer than JDK 8 simply won't work.
To fix the problem you should install the latest release of JDK 8 before repeating your installation of NetBeans.
Alternatively, you could download and install the latest version of NetBeans, Apache NetBeans 11.1. That approach is definitely preferable if it is feasible for you it since it offers three advantages:
You are using the latest version of NetBeans.
You are using the most recent JDK.
Since you have already installed JDK 13 you won't need to download any other JDK. Apache NetBeans 11.1 will run fine using JDK 13.
I have started developing an Android application in Android Studio. After starting Android Studio it gives me an error: "compileSdkVersion android-21 requires compiling with JDK 7". So I ran java -version at the Commmand Prompt and it shows I have 1.7. But in Program Files there is a folder for JDK 1.6 but not for 1.7. JRE of 1.7 is there, but not JDK 1.7.
Any suggestions will be appreciated. Thanks in advance.
Try "javac -version" instead of "java -version" to confirm JDK installed version
It seems that you have a 1.7 Java Runtime but only 1.6 SDK installed.
Just get the correct SDK installer from java.com.
Uninstall all jres and jdks, reinstall the jdk you need (jre is included). Be carefull with the bit-versions, always install the correct one
new:
Idea is you can simply set you projects jdk any version you want, different from os installed one, just make sure you download it and referenece from the android studio

I have just installed WindowBuilder for Eclipse and java 1.7 JDK, but when I create a new JFrame in Eclipse, and try to open the "design-view" in WindowBuilder I get the following error: "Eclipse is running under 1.6, but the Java project has a 1.7 Java compliance level, so WindowBuilder will not be able to load classes from the project. Use a lower level of Java for the project, or run Eclipse using a newer Java version."
How to Resolve Incompatible Java version Error in Eclipse in mac?
You might have installed the Java 1.7 SDK but it looks like Eclipse is started with the older one (1.6).
The WindowBuilder is integrated into Eclipse and will use the same Java instance as Eclipse (that is the 1.6 version).
However your project will use Java 7. The WindowBuilder (Java 6) will be unable to load classes from the higher version which your project uses (Java 7).
What you need to do is:
Configure your eclipse to start with the newer (Java 7) version. This can be done in the Eclipse.ini file.
Which Eclipse you're running?
You definitely need to upgrade your Eclipse to a newer x64 Version to use Java 1.7.0
