Reinstall Java 7 JDK on OSX

Question

I tried installing Java 7 (aka 1.7) on OSX 10.7.5 (Lion).

Unfortunately, it seems that all this has mixed up Java, and I'm not sure how to solve the problem. Currently, when I try to start Eclipse, I get an error:

The JVM shared library "/System/Library/Frameworks/JavaVM.framework" does not contain the JNI_CreateJavaVM symbol.

Programs such as Minecraft and PhpStorm will be completely destroyed without errors.

Running "java -version" in the terminal gives me:

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) 

Which, I understand, should be expected with a direct installation of Java 7. Unfortunately, Utilities → Java Settings have been removed in OSX 10.7.5, and an attempt to load System Preferences → Java Panel does not work (this says that it opens in a new window, but does not appear when a button appears to reload it by clicking it to do nothing).

I tried reinstalling various versions of JRE and JDK to no avail.

Is there anyway to lay out the lot and start again, or am I missing something really obvious?

Answer 1

Find out where the installation directory of your Java 7 on your Mac OS X is located. Set the JAVA_HOME shell variable to this directory (the directory must contain the bin and lib subdirectory). Edit the path to export PATH="${JAVA_HOME}/bin:${PATH}" . Try java -version .

If all else fails, you may need to reinstall the OS to return the default values ​​for Mac Java and just reinstall Java 7.

I had a similar problem in Mountain Lion (10.8): after installing the Java 7 SDK, I removed the Java 6 JRE installed by Apple. It ruined my computer, especially Eclipse. The problem is that Apple released the official Java JRE for Mac OS X until Java 7 came out, and Oracle became the official supplier of this version. After I reinstalled the OS, I was able to get a help window that asked me about loading the Java runtime. This will reinstall the Java Java 6 JRE.

I had the same problem. I tried several solutions, but in the end, installing Java for OSX from the Apple website fixed it.
