If we follow the instructions of the Spectrum help we need to Install the Java 2 Runtime Environment (see the previous post). Then like the JRE includes the Java Web Start client, which is required to run JNLP applications like SPECTRUM OneClick Console, we need to associate the .jnlp extension with de javaws (Java Web Start) program.
So in this order do:
1) Go to the Spectrum OneClick console web page
2) Click on "Start Console"
3) Save the
oneclick.jnlp file to disk.
4) Right-click on the .jnlp file that you downloaded, and select “Open with Other Application…”
5) Select “Use a custom command”, and click “Browse…”.
6) Locate your java installation folder and select the file $JAVA_HOME/jre1.6.0_01/javaws/javaws/.
On my system, that works out to /home/user/jre1.6.0_01/javaws/javaws
7) Click OK.
8) Restart Firefox and click again over "Start Console". Now a window like this should appear:
Then start the download of the application an after that the Spectrum Console appears in the screen. Easy and quick.
Explanation
The Java Web Start MIME type is not properly associated with the javaws binary. You have to explicitly set the association, then restart Firefox for it to get the update.
