I can't set up JAVA_HOME. Before you dismiss this as a noob's question who can't figure out how to google things let me explain my situation.

I bought RaspberryPi and installed raspbian onto SD card following tutorial steps. Everything seemed normal until I started tinkering with it and installing some stuff like maven, tomcat, logstash or solr.

Every tool complained about not finding java in JAVA_HOME. No biggie. I found which java, followed some symbolic links to find java in /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/bin/java. Java came with my raspbian I didn not install it. So I added:

export JAVA_HOME="/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt"
export PATH=$PATH:$JAVA_HOME/bin

at the end of ~/.bashrc I'm no sysadmin but I did that a couple of times so no worries.

I was wrong. Regardless of where I put those lines (/etc/environment, ~/.bsahrc, ~/.profile) JAVA_HOME doesn't seem to be set up. When I echo $JAVA_HOME lo and behold there it is, pointing as supposed to.

When I type mvn -v it returns:

Error: JAVA_HOME is not defined correctly.
  We cannot execute /usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/bin/java

So I checked permissions:

pi@raspberrypi:~ $ ls -laR /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/bin/java
-rwxr-xr-x 1 root root 3384 Dec  9  2015 /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/bin/java

But everyone has +x

I tried rebooting, using source, nothing works. I'm out of ideas. Pleas help me Raspberry aficionados.

Your JAVA_HOME points to a different directory than where your java executable is located. Per your question, the JAVA_HOME directory is:

/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt

whereas java is located in

/usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt

Note the arm vs. arm32.
