Hi to everyone
Recently I installed JDK in my Ubuntu 12.04. The problem is that I installed more than one instance of JDK until I managed to make it work. I think I installed two .sh filed which I downloaded from oracle's website and two instances from the software center of Ubuntu. Now I am trying to clean up everything and make a right installation of the jdk. I think that I have managed to delete the isntances by removing the folders from the /usr/lib/jvm/*jdk*
When I am running the command
java -version I get
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)
when I run the command
javac -version I get
The program 'javac' can be found in the following packages:
* default-jdk
* ecj
* gcj-4.6-jdk
* openjdk-6-jdk
* gcj-4.5-jdk
* openjdk-7-jdk
Try: sudo apt-get install <selected package>
What does this means? Do I have uninstalled all the jdks?
And also when I run the command sudo update-java-alternatives -l
then I get
java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64
java-1.7.0-openjdk-amd64 1051 /usr/lib/jvm/java-1.7.0-openjdk-amd64
but there is not such folders in the /usr/lib/jvm/ directory. Is it proper? Do I have to empty the sudo update-java-alternatives -l command's list?
Thanks in advance
