Fiji webstart error

[Krs5]

Dear Fiji developers,

I had a go at Fiji using Webstart but am not able to run it as I get: Application Error. Unable to launch application.

With the following exception:
Error: Found unsigned entry in resource: http://download.java.net/media/java3d/webstart/release/j3d/1.5.2/j3dcore.jar


Exception:
com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: http://download.java.net/media/java3d/webstart/release/j3d/1.5.2/j3dcore.jar

I am very sorry: Fiji Webstart fell a bit unmaintained since nobody used
it. To be precise: it has not been updated since end of June *last* year.

If you need it, I will try to find some time to fix it, though. Do you
want to use it in your courses, or where does your interest in
Webstart'able Fiji come from?

Ciao,
Dscho

Okay, but note that it usually downloads the complete Fiji, so if the goal
was also to save on bandwidth, there are better ways.

Yes, but to "install" Fiji, it is enough to unpack the .zip file on the
Desktop and launch it there.

Or fix it. The problem is that Oracle decided to remove the signed .jar
files because they did not want to maintain Java3D and JOGL:

Alas, I fixed the problem you described.

I still have to find time to make a Jenkins job to keep it up-to-date,
though!
