Getting-Started:
Guides to Installing the Tomcat7 Server on Linux Ubuntu:
This is not a very good tutorial, sorry.
RispondiEliminaYou say:
mv /tmp/jdk1.7.* /usr/lib/jvm
And then:
update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.*/bin/java 1065
But we just moved the "content" of the folder jdk1.7.* into /usr/lib/jvm
So it should be:
update-alternatives --install /usr/bin/java java /usr/lib/jvm/bin/java 1065
Furthermore you say "to change java version enter the selection number in the first column."
What selection number?
What column?
Hello Daniel,
RispondiEliminathanks for Reading and Commenting here :)
Look Better because...
The Tutorial is Just Working As Is!
Only Check if /usr/lib/jvm Exists Before Moving.
If Not, then Make it with: mkdir /usr/lib/jvm
Cheers,

Thanks for sharing it. Although the tutorial works fine, it would have been much better to have presented it in a better way but thanks anyway.
