etx: External Launch Error: Could not launch JNLP file. (could not find any suitable runtime)

[JavaUser20]

I'm trying to replace Oracle's Java with an opensource solution. I'm using DHL's silent.jnlp for Zebra printing. When I try running the .jnlp they supply I get the following:

Could you please attach the JNLP file to this ticket. As the reason for the error is most likely to be found there

silent.zip

I attached the JNLP file here. Please let me know if it doesn't work.

Here the plain text:

OK the problem is that the JNLP file is missing the required Java version. Add the following line to <resources>

        <java version="1.8*"/>

This will select a java 1.8. If you replace the * with + it will take the newest java available.

That definitely seems like that's the problem. I was able to edit the JNLP and run it from the desktop and the app ran.

I'm so close, yet so far away from getting this to work.

The problem I have now is that DHL has a "Print Waybill" icon, which downloads the JNLP which is in the original form (doesn't have the tag. So naturally, it doesn't work. :(

Is there any way I can work around that with OpenWebsStart? Is there a way to have OpenWebStart ignore the missing tag? Oracle's webstart must ignore that tag missing since it works ok with Oracle's non-opensource friendly version.

I implemented a fallback to 1.8+ in #101 next version of OWS will have this issue fixed

[JavaUser20]

I'm sorry for my ignorance, I just found out about OWS a few days ago. When will the next release be available? OWS seems like a very viable solution to my Oracle problem.

[sclassen]

have a look at https://openwebstart.com/#openwebstart-roadmap It will be early December but a date is not yet fixed

[JavaUser20]

I will be waiting for the next release eagerly.

Thank you for all the hard work you put into this project. :)
