    64 bit and java

    I tried to install with the universe and multiverse repositories.
    Negative, apt-get install sun-java5-jre or sun java5-jdk never heard of it.

    here is my repositories.

    deb http://ca.archive.ubuntu.com/ubuntu/ dapper main restricted

    now I also downloaded the 64 bit version from www.java.com says to use the 32 bit version. figure the 64 has to be the 32.

    follow sun's instruction and put it in /usr/local. its all there down to the word DONE when it was finished.

    I logged out and back in just in case.

    here is the command to see the version I have installed.
    root@krynn:/home/michelle# java -version
    java version "1.4.2"
    gij (GNU libgcj) version 4.1.0 (Ubuntu 4.1.0-1ubuntu8)

    root@krynn:/home/michelle#


    I install version 1.5.0.07

    I used the command
    root@krynn:/home/michelle# update-alternatives --config java

    to choose the new version but its not there.

    Typing aboutlugins in firefox says no plugin at all.

    So what do I do?

    Thanks for all the help I get in advance.

    Re: 64 bit and java

    Hello,
    I new in the kbuntu world(but not in linux), I supose that finding a propìery implementation of java like the sun's one in a repository is not easy. Only very few repositoies include propietary software.

    In the other hand It's very easy to find a free implementation of java like kafeine ....

    If you want sun's java, download it (jre and jdk) from sun.com, It's very easy to install and free of charge (I think that source code is not free but there is not limitations ).

    If you have installed jdk javac -version should tell you which version of the compiler you are using.

    The problem is that you have already installed a free implementation of java. (ubuntu did it for you)
    If you go to /usr/bin you probably find a simbolic link pointing to the free implementation of java.
    Go there and put in the console ls -l javac if this link does not point to the diretory where you have installed java, you have found the problem.

    To fix it you can rename /usr/bin/javac to /usr/bin/whateveryouwant and create a new simbolic link javac pointing to your java installation(compiler). That would be enought. (there is no need of uninstalling old java but I think it would be better).

    java2 -> /etc/alternatives/java
    javac -> /usr/local/jdk1.5.0_07/bin/javac

    I renamed javac to java2 and then I created a new simbolic link pointing to the sun's java

    To install the plugins is a easy task too.
    If you have installed jre you can find a directory named plugins.
    You have to create a simbolic link into firefox/mozilla plugin's directory pointing to the pluglin you need in that directory(jre).

    libjavaplugin_oji.so -> /usr/local/jre1.5.0_07/plugin/i386/ns7/libjavaplugin_oji.so

    Don' t forget paths

    example:

    #variables de entorno
    export JAVA_HOME=/usr/local/jre1.5.0_07
    export PATH=$PATH:/usr/local/jre1.5.0_07/bin
    export PLUGIN_HOME=/usr/local/jre1.5.0_07/plugin
    export CLASSPATH=$CLASSPATH:/$PWD:/usr/local/jre1.5.0_07/lib/ext/mysql-connector-java-3.1.13-bin.jar
    :/usr/local/tomcat/common/lib/servlet-api.jar



    I hope you find this information usefull.

    bye
