Java安装冲突Fedora

Question

I have fedora 19 and installed JDK as default, version 1.7, But ADT Eclipse for web development was giving problem, it only accepts versions < 1.7. I was, I removed everything and installed jdk-6u45 from the oracle site, I installed as rpm -ie good, when using java-version appears as follows:

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)

after all, installed or not installed? removed the java 1.7 or n? How to solve this problem and have only the 1.65 that I downloaded from the oracle site? Apparently both are installed.

Add these lines to your ~/.bashrc (you may need to change the path to the one on your system):

export JAVA_HOME=/usr/java/jdk-1.6.0_45
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
