"which java" in CentOS prints wrong java path

view story

http://stackoverflow.com – I am not sure why "which java" and "whereis java" paths are not correct. I tried to edit ~/.bash_profile and /etc/environment but did not help. The desired path is what is seen in "echo $JAVA_HOME" below but the same is not reflected in "which java" Below is what I get in CentOS 6.4: which java /usr/bin/java java -version java version "1.7.0_45" JAVA(TM) SE Runtime Environment (build 1.7.0_45-b18) JAVA HotSpot (TM) 64-bit Server VM (build 24.45-b08, mixed mode) whereis java java: /usr/bin/java /etc/java /usr/lib/java /usr/share/java echo $JAVA_HOME /usr/java/jdk1.7.0_45/jre (HowTos)
