Hello everyone.
I want to install SweetHome3d on Fedora 12 via Java Web Start. Here is what I am doing:
- click on "Launch Sweet Home 3d with Java Web Start" link in Mozilla Firefox;
- in the dialog box I select "Open file with: javaWS";
- after SweetHome3d.jnlp file is downloaded, nothing is happening for some time;
- suddenly dialog box appears, saying that:

Downloading Sweet Home 3d: 0% complete.
- www.sweethome3d.eu/lib/SweetHome3d.jar
- www.sweethome3d.eu/lib/Loader3DS1_2u.jar
- www.sweethome3d.eu/lib/freehep-vectorgr ... -2.1.1.jar
- www.sweethome3d.eu/lib/sunflow-0.07.3c.jar
- www.sweethome3d.eu/lib/jmf.jar
- www.sweethome3d.eu/lib/iText-2.1.7.jar
- www.sweethome3d.eu/lib/linux/i386/java3d.jar

Nothing is happening after that.

I have Java version 1.6 update 18 (build 1.6.0_18-b07) from Sun Microsystems installed.

How can I solve that problem?

Thank you very much in advance.
