Installing on Solaris and Linux

The Solaris and Linux versions of Java Web Start is delivered as a ZIP file. The ZIP file contains the installation script, install.sh, along with the readme.html. The installation script is a shell script for Solaris, and a bash shell script for Linux. The installer does not come with a JRE, so that must be preinstalled on the system.
When you are prompted for a place to save the Java Web Start installer, pick a directory that would make a sensible permanent home for your copy of Java Web Start, for example, your home directory.
When the download finishes, unzip and execute the Java Web Start install script. The script will prompt you for the location of a Java 2 compatible JRE. In order to use Java Web Start you must have a version of Java 2 standard edition installed. If you do not, you can download one from http://java.sun.com. Please enter the path of your installation.
The installer will create the javaws subdirectory and install all the Java Web Start files into it.
The installer also updates the .mailcap and .mime.types files, so Java Web Start will be invoked when Netscape Navigator encounters a link to a JNLP link. On Solaris, it installs hooks into CDE so double-clicking on .jnlp files in the File Manager will also launch Java Web Start.
Make sure to restart Netscape to ensure that it picks up the new MIME type.
