User Notes:

Installation of IcedTea-Web

Install IcedTea-Web by running the following commands:

./configure --prefix=${JAVA_HOME}/jre    \
            --with-jdk-home=${JAVA_HOME} \
            --disable-docs               \
            --mandir=${JAVA_HOME}/man &&

This package does not come with a test suite.

Now, as the root user:

make install &&
mandb -c /opt/jdk/man

To test the man pages are correctly installed, issue man policyeditor to display the respective man page.

If desired, you may install a .desktop file corresponding to an entry in a desktop menu for policyeditor, as root user:

install -v -Dm0644 itweb-settings.desktop /usr/share/applications/itweb-settings.desktop &&
install -v -Dm0644 javaws.png /usr/share/pixmaps/javaws.png

Command Explanations

--with-jdk-home: This switch provides the location of the installed JDK.

--disable-docs: This switch disables installation of additional developer-related documentation. Omit this switch if you would like to do development work on IcedTea-Web.

Configuration Information

As the root user, create a symbolic link to the plugin from your browser(s) plugins directory:

ln -s ${JAVA_HOME}/jre/lib/ /usr/lib/mozilla/plugins/


The plugin must be a symlink for it to work. If not, the browsers will crash when you attempt to load a Java application.
