installing Java 7

[HappyLinux]

I've been searching the internet trying to find out how to solve this, but to no avail. So I'm hoping someone in here can point me in the right direction.

I'm currently on Mint 12, but will be moving up to Mint 13 in due time. However, I'm posting in this section because it might be relevant to whomever has this sort of problem with Ubuntu 12.04.

I currently have install sun-java6-plugin and sun-java6-re (installed by default upon installing Mint, instead of OpenJDK6).

The thing is, I would like to update to Oracle Java 7, not OpenJDK7.

The thing is, I've previously found that the OpenJDK just doesn't cut it with some of my needs. Some of the websites that I go to check to see what version of Java I'm running, and they don't recognise OpenJDK, and thus don't work, but they do with Sun/Oracle.

So until I update to Mint 13, how do I update to Oracle Java 7? I don't want the development part, just the runtime part.

Searching the web keeps yielding results for Java6 and OpenJDK, and even articles that are several years old.

I've downloading the Java7 package from www.java.com for my 64bit OS just in case.

Oh yes, I also found an article that Ubuntu 12.04 comes default with OpenJDK, and that if you want Java7 instead, you have to manually deactivate OpenJDK, then uninstall it, then remove excess files, then download the files from the Java website, install, and then activate it.

That seemed somewhat confusing as I thought it was a matter of just going to the software manager and uninstall OpenJDK. No faffing about with deactivation etc.

Well, can anyone help??

You don't need to purge OpenJDK if you already have it. In fact, I would keep it because it is open source. You might want to remove the IcedTea plug in if you wish.

You can have as many JRE/JDKs as you want and switch between them.

If you only want the JRE, you should install that from the Oracle website. However, unlike the this suggestion and the one above, you will have to manually install updates as Oracle makes them available.

use free java runtime environment:

$sudo apt-get install openjdk-7-jre

and for browser plugin:

$sudo apt-get install icedtea6-plugin

and SDK:

$sudo apt-get install openjdk-7-jdk

The OP said he did not want OpenJDK, but Oracle Java.

I'm not interested in OpenJDK because it doesn't work with what I do.

I don't have OpenJDK and IcedTea installed anyway, so switching between them isn't important. I'll manually install/update if I have to, I just don't know how when it comes to Java. I downloaded what Oracle provides, but it's in many files, across several folders/directories.

As I said in the post cited, the process is done for you in three easy commands in the terminal. The creators of the two available PPAs have scripted the whole process. I know for certain the webupd8 PPA works fine, as I use it exclusively.

There is no need for you to figure out what to do with a bunch of files.

Just execute the three commands and you are done.

You will get Oracle Java, not OpenJDK.

I read through the comments and noticed that people have been having trouble after following the instructions given on the page. I don't want that hassle.
