    Question Are we going to see Java SE 6?

    Java SE 6 is released and came with lots of new features and a big speed boost. The Distributors License for Java SE 6 is ready so we could expect a version packaged for Ubuntu.

    Java SE 5 was released for Dapper after Dapper was released, so I hope we can install some sun-java6 packages (hopefully along with the sun-java5 packages). Are we going to see sun-java6 packages for Edgy??

    Another question. Why sun-java5 packages are not updated when a new version is released? I installed sun-java5 v1.5.0-06 on Dapper and v1.5.0-08 on Edgy, and now I see v1.5.0-10 on Fiesty. Why v1.5.0-10 is not available for Edgy if it is a bug fix release?

    Anyone has comments?

    Thanks,
    rivas

    I very much hope that Fiesty will have JRE6 and JDK6 in its package repositories.

    But realistically speaking, an upgrade to Java 6 is really not that much of a priority at the moment. Most enterprises will not be adapting Java 6 so soon after its release. Therefore, most professional Java programmers will not be working with Java 6 either, unless it is purely for private or non-business use.

    If I had my way, I'd like to see Java 6 JRE and SDK on Feisty. Feisty's release is still some months away, so surely a very significant piece of software like Sun's Java could be packaged for it.

    Re: Are we going to see Java SE 6?

    You can always install jre-6 manually, by:
    1. uninstalling any previous versions
    2. downloading the new jre-6 from sun http://java.sun.com/javase/downloads/index.jsp
    3. reading the instructions http://java.sun.com/javase/6/webnote...elf-extracting
    4. moving it under /usr/lib/jvm/
    5. chmoding +x the binary (you can't build debs with fakeroot and java-package at the moment)
    6. executing the self-extracting file
    7.(not necessary after post #5) (updating the links of /usr/bin/java and /usr/bin/java_vm to the new java location, since the update-alternatives --config java mechanism for selecting java doesn't work anymore)
    8. updating the mozilla, firefox, swiftfox, opera java plugin links.
    see also the notes from sun about the java plugin http://java.sun.com/javase/6/webnote...ux.html#plugin

    It's better to wait for debian and/or ubuntu to include the new jre-6 in the java-package tool for building the relevant debs, cause then you can use the alternatives mechanism cleanly to select the java you want to work with, and not break your system.

    see http://www.azureuswiki.com/index.php/Java a how-to update to a newer java. Be carefull though to select up to 1.5.0-10 because the tools to build the debs don't work with jre-6.

    You can add java 6 to update-alternatives:

    Code:
    sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0/bin/javac 30
    sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0/bin/java 30
    
    sudo update-alternatives --config javac #then choose javac6 
    sudo update-alternatives --config java #choose java6

    Re: Are we going to see Java SE 6?

    I recommend to add this too:
    Code:
    sudo update-alternatives --install /usr/lib/firefox/plugins/libjavaplugin.so firefox-javaplugin.so /usr/lib/jvm/jdk1.6.0/jre/plugin/i386/ns7/libjavaplugin_oji.so 30
    and then:
    Code:
    sudo update-alternatives --config firefox-javaplugin.so
    and choose a 1.6.

    Re: Are we going to see Java SE 6?

    it works perfectly if you just run the setup file in /usr/lib/jvm then change the link
    java-1.5.0-sun
    to point to the new 1.6 folder

    Self made package is very easy...

    As I am a java developer I need the sdk. So here is my howto for installing the j2sdk. The jre has got less tools to update in the alternatives.

    Repository packages you'll need
    • build-essential
    • fakeroot
    • java-common


    Install the patched java-package
    Download the patched java-package from this post or my attachment below. Untar it
    Code:
    tar xvfz java-package-0.28ubuntu1.tar.gz
    Install it
    Code:
    sudo dpkg -i java-package_0.28ubuntu1_all.deb
    Create the package
    Download Java 6 from sun and cd into the same directory. Now issue
    Code:
    fakeroot make-jpkg jdk-6-linux-i586.bin
    Finally install it
    Code:
    sudo dpkg -i sun-j2sdk1.6_1.6.0_i386.deb
    Update the alternatives
    general for jre
    Code:
    sudo update-alternatives --config java
    sudo update-alternatives --config javaws
    sudo update-alternatives --config firefox-javaplugin.so
    sdk alternatives
    Code:
    sudo update-alternatives --config javac
    sudo update-alternatives --config rmiregistry
    sudo update-alternatives --config rmic
    sudo update-alternatives --config rmid
    Better check all your alternatives. I prefer to leave the jar tool with gcj as this native and has no new features.
    for sun java
    Code:
    ls -la /etc/alternatives/ | grep j2
    and for gij stuff
    Code:
    ls -la /etc/alternatives/ | grep java
