Thread: Java (OpenJDK) question

  1. #1

    Default Java (OpenJDK) question

    I really don't have any need for Java in any shape or form.
    I don't need it in the web browser either.
    I understand that it comes already installed but I would prefer to uninstall it.

    What would be the best way ?
    Search for java in the package manager and mark everything found for removal, then proceed with removal ?

    I'm not that familiar with Linux in general so forgive me for asking this, but is there anything in the default installation of openSuse that requires Java ?

    Can I safely remove it and not affect OS in any way ?

    I'm using 12.2 KDE version, default apps installed apart from XBMC and Clementine.

    Thanks.

    Use the package manager to remove it. If it's needed for another
    package, the package manager will tell you what the dependency is and let
    you either remove it and the programs that require it, or to keep it and
    not break the dependency.

    That said, if you don't need it (but it's required for something that's
    installed that you do need), then arguably you do need it - but it
    doesn't hurt anything for it to be on the drive doing nothing.

    Why would you want to remove it at first? LibreOffice for example wouldn't find a valid Java Runtime Environment anymore.
    My advice: just leave it where it is, as long as you don't need it, it won't hurt you, and when you do need it, it will be there.

    Well I just don't like it, what can I say

    Anyways, I've uninstalled java browser plugin only (icedtea-web) and that worked great, no more java in the browser

    As for the runtime environment .. I'll think about it, I'll probably remove it and see what exactly depends on it.
    If there are problems I'll bring it back.

    Java will also show up using unexpected names.

    So, for instance "Iced Tea" is a version of Java often used and commonly is the Java plugin nowadays for Firefox (Simply disable it in the Plugins section in FF).

    That should do the trick.I believe you are removing your JRE after reading various articles in the web.
    You are not safe even now. To be completely safe remove adobe plugin. Remove flash too :-). Disable all plugins in your browser.
    Navigating to this page should not show any plugins. https://www.mozilla.org/en-GB/plugincheck/
    Wait a minute. Isn't there a iframe based virus spreading on the net?
    Use text browsers(w3m,links,lynx,emacs-w3) to be completely safe.

    Take it easy guys, there's no reason for sarcasm

    Yes, one of the reasons for removing it is security, but that's not the main reason.
    I like to have a clean system as much as possible, if I don't need something I'm gonna remove it.
    WHY is not the issue, it was a simple question, I just wasn't sure if OS itself require Java for some reason.
    Individual apps that need Java are not the problem for me.

    Guess I should have shoot first and asked questions later

    No, why is very important. I have noticed many questions over the years where what they ask is not really what they want. In any case you had an answer that libreoffice might complain if it does not find a jre.

    That is not true. Read this: How To Ask Questions The Smart Way (and maybe a bit more there).

    People here are very helpful in general. But it is already difficult enough to get an idea about other people's knowledge level, what they are doing, seeing, hearing on their systems. Every piece of information that makes it easier to understand what an OP is trying to achieve makes a good advice easier. Just giving a stupid direct answer to a question is a good joke now and then (and computers do it all the time), but in the end it helps nobody.

    You must also except that this is a community. Not a helpdesk. Thus your question/problem will be read by many (coming here directly ot via Google) and a good thread where goal, problem, solution(s) and the pros and cons of all this is discussed, might help others in getting new ideas and managing their systems using good practices.
