When OpenJDK java web start is used, it can not open some jnlp files.
For example, you can try the following ones :
http://www.spark-angels.com/telecharger-1/
http://sweethome3d.sourceforge.net/SweetHome3D.jnlp

If you open them through firefox, it downloads the necessary jars, but does not open the application.
If you download the jnlp files and launch them whith javaws, you get the following error :
netx: Spec version not supported (supports 1.0)

These application work if you launch them with Sun Java 6 Web start.

Netx seems to be the library used by openjdk to handle jnlp files. I
checked the source code and it only supports 1.0 version of jnlp (see
file Parser.java in package netx.jnlp). The examples above use version
1.5 of jnlp.

What is annoying is that the upgrade from gutsy to hardy makes openjdk the default java alternative, even if Sun java 6 was installed.
Thus, the jnlp files that were working under gusty do not work anymore under hardy.

The workaround I currently use is to choose another location when
firefox prompts me which application to use for jnlp files : I specify
/usr/lib/jvm/java-6-sun/bin/javaws instead of "OpenJDK Java Web Start".
So the jnlp files are opened with Sun Java instead of openjdk : I still
need to keep Sun java.

The solution would be, I guess, to make netx support 1.5 jnlp files. But
this project doesn't seem to be updated for years...

That's a known bug that has been fixed in IcedTea6 hg tip. Please see https://bugzilla.redhat.com/show_bug.cgi?id=507870 for more information.

Great. I am now able to run the SweetHome3D jnlp, but not the spark-
angels example provided in the original report. Here is the result when
run from a terminal:

However, this does launch without barfing using Sun's proprietary javaws.

This is a bug in Netx's classloader and isnt related to JNLP 1.5 support. If there are no other issues, I will close this bug as FIXED.

Cheers,
