[SOLVED] Configuring oracle java in debian 10

[ratrace]

From oracle site i downloaded the file "Linux x64 Compressed Archive" for my 64-bit, debian 10 system.

As root user i created the folder /usr/local/java, moved in the folder the downloaded file and install it with the command tar zxvf jre-****.tar.gz. After the installation i deleted the .tar.gz file.

I'm trying with the command update-alternatives --config java, to make oracle java the default java program, but when i give the above command, the outcome is,

Code: Select all

There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-11-openjdk-amd64/bin/java
Nothing to configure.

How can i set the oracle java as the default java program instead of openjdk?

you need to install the new option

Code: Select all

update-alternatives --install link name path priority [--slave link name path]...

in slave specify the existing java package's details

It's very easy to wreck an alternative when attempting to add a new option manually via the command line[0] so perhaps use the GUI instead: https://packages.debian.org/buster/galternatives

[0] Well, it was easy for me

Thank you. It worked.

Code: Select all

update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jre*****/bin/java" 1
