What is the correct target for the JAVA_HOME environment variable for a Linux OpenJDK Debian-based distribution?

问题 In Windows, JAVA_HOME must point to the JDK installation folder (so that JAVA_HOME/bin contains all executables and JAVA_HOME/libs contains all default jar libraries). If I download Sun's JDK bundle and installs it in Linux, it is the same procedure. However, I need to use Kubuntu's default OpenJDK package. The problem is that all executables are placed in /usr/bin . But the jars are placed in /usr/share/java . Since they are not under the same JAVA_HOME folder I'm having trouble with Grails

Towards the “true” definition of JAVA_HOME

问题 As a Java developer who switches between *NIX systems (OS X, Ubuntu, ...), although I can always "get" my JDK up and running, it seems that there is no clear definition of JAVA_HOME in many packages which require JAVA_HOME to be set : For example MAVEN : "JAVA_HOME, refers to your JDK directory" HADOOP : "JAVA_HOME, which specifies the path to the Java 1.5.x installation" SUN : "JAVA_HOME is the directory that contains the JRE" I thus have 2 questions regarding this matter (any insights would

问题 I pointed the JAVA_HOME to C:\Program Files (x86)\Java\jre7 . It works fine. Afterwards, I unzipped ant and set up the environment variables related to Ant, I got the following error messages after typing "ant -version" I searched this forum. Looks like one solution is to point Java to JDK instead of JRE. I am not exactly sure whether this should be the solution. In other words, in general, which one should JAVA_HOME point to? JDK or JRE? 回答1: If you're doing any sort of development, or

How to set Oracle's Java as the default Java in Ubuntu?

How do I change the value of JAVA_HOME in Ubuntu to point to Oracle's Java? Should it point to java-6-sun or java-6-sun-1.6.0.24 ? srkiNZ84 I put the line: export JAVA_HOME=/usr/lib/jvm/java-7-oracle in my ~/.bashrc file. /usr/lib/jvm/java7-oracle should be a symbolic link pointing to /usr/lib/jvm/java-7-oracle-[version number here] . The reason it's a symbolic link is that in case there's a new version of the JVM, you don't need to update your .bashrc file, it should automatically point to the new version.

问题 I need to set the variables like JAVA_HOME and update PATH . There are a number of ways of doing this. One way is to update the /etc/environment variable and include a line for JAVA_HOME using the lineinfile module and then run the command source /etc/environment directly on the guest OS (CentOS in my case). Another way is to execute the export command e.g. export JAVA_HOME=/usr/java/jre1.8.0_51 export PATH=$PATH:$JAVA_HOME Is there a cleaner way to do this as all these require manipulating
