I am running KUBUNTU Linux and want to use the new Java6 Development Platform. Right now I have java4. What I can't figure out is how to tell the system to defualt to Java6 or remove Java4 and reinstall java6 into the proper directory. Everything is installed, but when ever I try to complie a program with javac, I get the error import java.util.Scanner cannot be resolved. Can anyone help me with this problem?
If you have the java binaries installed from the original KLUBUNTU distribution (e.g. Feisty) you will have a link from
/usr/bin/java -> /etc/alternatives/java -> /usr/lib/j2se/bin/java
and a similar construct for javac (or to a repacement program for javac like gjc)
I you have successfully installed the JDK v6 to "your directory" you have to build the new links only.
E.g. as root:
cd /usr/bin
rm java
ln -s "your directory"/jdk1.6xxx/bin/java java
rm javac
ln -s "your directory/jdg1.6xxx/bin/javac
This should work. You van verify this by typing
java -version
and
javac -version
Good luck
