I did these steps without error:
JDK path :
Downloads/jdk-6u37-linux-x64.bin
Commands in Terminal:
mkdir Programs cd Programs bash ../Downloads/jdk-6u37-linux-x64.bin ln -s jdk-6u37-linux-x64 jdk
Set JAVA_HOME and Path:
I added the following lines to the end of the .bashrc
file:
export JAVA_HOME=$Home/Programs/jdk export PATH=:$JAVA_HOME/bin:$PATH
This is the result of executing the command echo $JAVA_HOME
:
/Programs/jdk
This is the result of executing the command echo $PATH
:
:/Programs/jdk/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games1
And the problem is:
This is the result of executing the command
$ java -version
The program 'java' can be found in the following packages:
* default-jre
* gcj-4.6-jre-headless
* gcj-4.7-jre-headless
* openjdk-7-jre-headless
* openjdk-6-jre-headless
Try: sudo apt-get install
I think the problem is that environment variables are case sensitive in linux, so your
export JAVA_HOME=$Home/Programs/jdk
Should be
export JAVA_HOME=$HOME/Programs/jdk
In your echo $JAVA_HOME
output you can see that you don't get your /home/yourname
prepended...
Hope that helps.
Cheers,
The scripts located here will help you install sun's jdk on Ubuntu. Really useful stuff.
try this command
sudo update-alternatives --config java
This will list all the Java versions installed and configured.
If you see one or more installs, it will give you a list each element starting with a number. Just choose the number that corresponds to the version you want to use by default.
