    Exclamation Java browser plugin regulary crashes

    Scopus Document Download Manager uses java and IcedTea doesn’t runs it . So I decided to install Oracle Java as mentioned on https://en.opensuse.org/SDB:Installing_Java
    I installed jre-7u67-linux-x64.rpm, as I'm using openSUSE 13.1 x86_64 with firefox user agent
    Code:
    Mozilla/5.0 (X11; Linux x86_64; rv:31.0)  Gecko/20100101 Firefox/31.0
    It was successfully installed. The java website https://www.java.com/en/download/installed.jsp also says the same.
    Firefox about:plugins also says same
    Code:
    Java(TM) Plug-in 10.67.2
    
    File: libnpjp2.soPath: /usr/java/jre1.7.0_67/lib/amd64/libnpjp2.soVersion: 10.67.2State: EnabledNext Generation Java Plug-in 10.67.2 for Mozilla browsers

    Then it is probably application specific.

    I ran a chrome browser against the URL in your java console output.
    It looks like a new Tomcat server, but nothing is being served at the URL you're testing
    You can open a browser debugger yourself (In any chrome family browser (besides chrome, chromium and canary) with the keystroke CTL-SHFT-J, then navigate to your URL. You will see that the location exists, but nothing is being served.
    You can compare output navigating to any known working webpage.

    So, at least for me it doesn't look like the java plugin "crashed" -- The problem is likely server-side.

    vish,

    Just wondering your opinion and experience following the Java SDB.
    I assume you followed the top part which describes installing only the JRE.

    I have mixed feelings about what the SDB has changed into.
    From the original content,
    - I made improvements and updates as noted in the Discussion
    - Then, it looks like two new sections have been added
    The JRE section which is not entirely clear (BTW - The JRE approach can be substituted by simply
    running my JDK scripts and doing the plugin install per the instructions on the Oracle website
    total time probably < 10 minutes even for very slow people, prob < 1minute for anyone who
    knows what they are doing)
    An additional JDK section has been added has added for JDK 8, will need to be inspected
    Changes to the original JDK 7 instructions without clearly describing is only for JDK7

    So, can you verify which set of instructions you followed and whether you felt it was clear and concise?

    tsu2 java is perfectly running the 'Scopus Document Download Manager' on windows. So, I don't think so it would be a server-side problem.

    While running on windows there is a considerable lag after opening the given java app, for which time the app is unresponsive. But, after that lag the app works fine. Also, while running the same app on Java in openSUSE there is considerable lag but after that firefox notifies that java plugin has crashed.

    Yes, tsu2 I installed jre. And, regarding Java SDB, explanation of jre installation is simple and lucid but explanation of jdk installation is a little complex. Anyways, I don't require jdk.

    I didn't mean that anything is necessarily wrong with Java in general server-side but that the code which is supposed to be served from your server to your client does not exist.

    Since I don't know if your content is supposed to be dynamically created or is simply missing files, I don't know what your actual problem is... Only that when the browser requests something, it's receiving null (does not exist).

    So, I interpret it as, there is delay between browser request and server response. While in windows java is able to work even after the delay but in linux the java plugin crashes.

    And there is no problem in installation because java website verifies so. Will update the java plugin once again to see if it helps.

    tsu2: On the mozilla support forum https://support.mozilla.org/en-US/qu...#answer-625806 I got advise to check java 8. Should I?

    Or, the server knows it is not a Windows client, and refuses to serve.
