How to install java 7 on yosemite properly?

When I type java -version I see:

No Java runtime present, requesting install.

I go to download and install jre-7u75-macosx-x64. After that in preferences I see Java control panel which tells me that I have recommended version of Java (Java 7 update 75) but terminal says again that

No Java runtime present, requesting install.

When I type

export JAVA_HOME="/usr/libexec/java_home -v 1.7"

I see:

Unable to find any JVMs matching version "1.7". No Java runtime present, try --request to install.

Java control panel shows that Java located in

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java

What am I doing wrong?
