    Default java jre issue


    I upgraded this machine from using jre-6u37 to jre-7u17 (oracle). A java
    program I need starts and runs well, it appears. However, I wanted to
    check the java version, and got this:

    Code:
    cer@Telcontar:~> java --help
    Unrecognized option: --help
    Error: Could not create the Java Virtual Machine.
    Error: A fatal exception has occurred. Program will exit.
    cer@Telcontar:

    Does it simply mean that the "--help" or "--version" options are not
    recognized, or do I have something else missing?

    java does not follow the GNU style for options, you have to call it with
    Code:
    java -version
    java -help
    only one minus sign.

    one "-" as Martin says...which here gives

    Code:

    java version "1.7.0_05"
    Java(TM) SE Runtime Environment (build 1.7.0_05-b06)

    denverd@linux-os114:~>
    you can also test the browser part at
    http://java.com/en/download/installed.jsp

    which here tells my 11.4 evergreen has "Java version: Version 7
    Update 5" and

    so, did you put update 7 on your 11.4?? and how? (that is, did you
    use yast to install the rpm, or rpm command at the CLI? and did the
    oracle instructions work alright
    [http://java.com/en/download/help/linux_install.xml])

    AHH!! :-)

    How obvious. Once you know... or remember.

    That's on 12.1, later I can test in 11.4. I have to go out.

    Completion checkmark
    Congratulations!
    You have the recommended Java installed (Version 7 Update 17).

    I did not even read the instructions, or I forgot them :-)

    I simply downloaded the 64 bit rpm, and run "rpm --upgrade packagename"
    on it as root, that's all. Of course, I already had the 1.6 rpm
    installed, also from Oracle, so I did not have to change anything,
    worked out of the box.

    (and I tried first in my 11.4 box - java is not that crucial for me in
    there)


    Actually, I once followed the link at:

    Code:
    https://sites.google.com/site/easylinuxtipsproject/java-for-opensuse
    http://java.com/en/download/manual_v6.jsp

    but instead of using the bin package it recommends, I went for the rpm.
    It is much easier to upgrade to the next version once you install the
    first one.

    Code:
    cer@minas-tirith:~> java -version
    java version "1.7.0_17"
    Java(TM) SE Runtime Environment (build 1.7.0_17-b02)

    So, exactly the same - not surprising, I used the same rpm :-)
