LinuxQuestions.org - How to upgrade Firefox Java JRE to 1.5.0

Hi jackalista
I can tell you how I upgrade the java JRE in my system which is a tweaked SUSE Linux with Firefox as a browser :
1) The last version is called "Java Runtime Environment (JRE) 6"
see http://java.sun.com to download the Linux RPM in self extracting file.
the name of this file is 'jre-6-linux-i586.rpm.bin'
2) to extract the binary rpm do in a console as user login :

Code:

cd <download directory>

chmod 755 jre-6-linux-i586.rpm.bin

./jre-6-linux-i586.rpm.bin -x

rm jre-6-linux-i586.rpm.bin

you get the binary rpm file 'jre-6-linux-i586.rpm'
3) to upgrade to this new version do in a console as root login :

Code:

cd <download directory>

rpm -Uvh jre-6-linux-i586.rpm

You can have several java JRE versions on your machine, so you can keep the original 1.4 version installed.
4) to use the new version :
I change as root the environment variables in the files '/etc/profile.d/alljava.csh' and '/etc/profile.d/alljava.sh'.
For example I get for the file alljava.sh :

Code:

#    /etc/profile.d/alljava.sh

#

# send feedback to http://www.suse.de/feedback



#

# This script sets some environment variables for default java.

# Affected variables: PATH, JAVA_BINDIR, JAVA_HOME, JRE_HOME,

#                    JDK_HOME, SDK_HOME

#



if [ -x /usr/lib/java/bin/java ] || [ -x /usr/lib/java/bin/jre ] ; then

  export PATH=$PATH:/usr/lib/java/bin

  export JAVA_BINDIR=/usr/lib/java/bin

  export JAVA_ROOT=/usr/lib/java

  export JAVA_HOME=/usr/lib/java

  if [ -x /usr/lib/java/jre/bin/java ] ; then

    export JRE_HOME=/usr/lib/java/jre

  else

    export JRE_HOME=/usr/lib/java

  fi

  unset JDK_HOME

  unset SDK_HOME

  if [ -x /usr/lib/java/bin/javac ] ; then

    # it is development kit

    if [ -x /usr/lib/java/bin/jre ] ; then

      export JDK_HOME=/usr/lib/java

    else

      export JDK_HOME=/usr/lib/java

      export SDK_HOME=/usr/lib/java

    fi

  fi

elif [ -x /usr/java/jre1.6.0/bin/java ] ; then

    # it is IBMJava2-JRE or SunJava2-JRE

    export PATH=$PATH:/usr/java/jre1.6.0/bin

    export JAVA_BINDIR=/usr/java/jre1.6.0/bin

    export JAVA_ROOT=/usr/java

    export JAVA_HOME=/usr/java/jre1.6.0

    export JRE_HOME=/usr/java/jre1.6.0

    unset JDK_HOME

    unset SDK_HOME

elif [ -x /usr/lib/java/jre/bin/java ] ; then

    # it is IBMJava2-JRE or SunJava2-JRE

    export PATH=$PATH:/usr/lib/java/jre/bin

    export JAVA_BINDIR=/usr/lib/java/jre/bin

    export JAVA_ROOT=/usr/lib/java

    export JAVA_HOME=/usr/lib/java/jre

    export JRE_HOME=/usr/lib/java/jre

    unset JDK_HOME

    unset SDK_HOME

fi

5) To change the Firefox plugin do as root :

Code:

cd /opt/firefox/plugins

rm libjavaplugin_oji.so

ln -s /usr/java/jre1.6.0/plugin/i386/ns7/libjavaplugin_oji.so

Your Firefox installation directory may be another one, as I installed mine from the Mozilla binary tarball.
6) Do a logout/login

This method works well for me, I have no problem with the new Java JRE version.

Have an nice day.
