Error launching .jnlp

[f-ferraro]

Dear @rodrigoSantamaria, Thank you very much for this nice and useful resource.

I would like to use it but so far I have been unsuccessful to start the program.

I tried running the .jnlp on Windows 11. Javaws is started but after a while I get the following errors:

I also tried to run it in in Ubuntu 22.04 with similar errors.

Could you please help me with this?

Thank you in advance! Best regards, Federico

Dear Federico, Thanks a lot for considering Voronto :) If the java web start is not working, you can run the .jar file directly from a terminal with java -jar voronto.jar

Java version should be 11+, but it will probably run ok with 1.8+ The jar file can be downloaded from http://vis.usal.es/voronto/voronto.jar

I'll check what's wrong with jws and let you know.

Cheers, Rodrigo
