So I’m working on my first .jnlp file. First of all can you make these in note-pad(it’s XML right)? :persecutioncomplex:
I keep getting this error and it’s confusing to me because I definetly have a tag(you can check me code below)

I understand what the commands do, but this is my first run in with these files, and I’m not sure what web-start is expecting.

Google helps but it only got me 90%(approx).

Thanks for reading!

#2

I think the error was because I used a regular jar and not an executable jar
So I found out I need to sign the .jar buttt whenever I bust open command prompt it says keytool doesn’t exist?

I already advised you to watch my JNLP file but you haven’t done it:

Notice that you don’t need to deploy JOGL by yourself.

Don’t forget to add a new line at the end, it is a stupid mistake that I did some years ago when I had to fix something in my JNLP file, some editors do not do this automatically.

#4

I do have that line in my file. I added the other lines because that’s what this one tutorial said to do. I actually stole a lot of your jnlp file (hopefully that’s okay). I got rid of those resource OS lines, because after looking at them again I shouldn’t have them in there.
I have an empty line at the end too.

Do you have to sign .jar’s? or is that optional? I can’t find the tools for it if so.

I think the main problem is how I’m hosting it on angel-fire(free-website garbage)…
I’m getting a different error now.

edit: found the jar signer let’s hope my command prompt skillz are still on haha

I figured it all out!!!Gosh I’m so glad dos is dead.
my mac friends still can’t see it :frowning: I guess it just says “Unable to load”
here’s the .jnlp

and here’s the link.|edit: | new url = http://www.angelfire.com/psy/reformation/RunNous.jnlp

#6

I didn’t understand why you deployed the native files of JOGL twice (once through the extension name, once explicitly in your JNLP file). Good luck.

Edit.: it would be fine if we succeed to repair our JNLP files in order to allow them to work with OpenJDK.

#7

haha I’ve already had enough of this .jnlp nonsense. I think Java needs a more sensible method to deploy web-start applications. It’s almost as if Sun doesn’t really want people to use them or something. Anything involving the command prompt IMO is dodgy, it’s 2009 man.I take that back I just thought about how the JDK/JRE has to work and it makes sense that it’s a fairly practical way to deal with that issue. haha.

Also gouessej I fixed that weird thing I was doing having two .jnlp files, that was pretty dumb of me haha

Thanks for helping me get it to work for windows! ;D

btw any passer-by reader’s here the tutorial for signing:
http://www.cokeandcode.com/webstarthowto

and your keytool and jarsigner are in your JDK’s BIN folder.
