I am facing the problem while running the java program from command line. I have openjdk-6-jdk installed in my linux system and still shows the error relates with the openjdk-7-jdk.
Initially i have jdk 7 installed in my system but ater i have removes it but still facing problem while running the application.
after running the cammand
sudo update-alternatives --config java
it shows warning as follows
update-alternatives: warning: /etc/alternatives/java is dangling, it will be updated with best choice.
There is only one alternative in link group java: /usr/lib/jvm/java-7-openjdk/jre/bin/java Nothing to configure.
what should I do?
Assuming you installed the OpenJDK6 with:
sudo apt-get install openjdk-6-jdk
In Ubuntu 64 bit, make sure the paths are valid for your installation (change if using 32bit version):
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java /usr/lib/jvm/java-6-openjdk-amd64/bin/javac
Setup update-alternatives:
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/java-6-openjdk-amd64/bin/javac" 1 sudo update-alternatives --set java /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java sudo update-alternatives --set javac /usr/lib/jvm/java-6-openjdk-amd64/bin/javac
Alternatively, make sure the correct version is checked for both Java and compiler:
sudo update-alternatives --config java sudo update-alternatives --config javac
List the installed Java alternatives with:
sudo update-alternatives --list java sudo update-alternatives --list javac
update java alternatives:
sudo update-alternatives --config java sudo update-alternatives --config javac
