I have a problem where I can't open up .jnlp files. I see the java web start is running in the task manager but nothing appears. I had tried to reinstall java clear temp appdata software disruption and cache and turned off firewall and antivirus but that didn't solved it.
I also tried to run it on another Windows 10 machine and there it would run perfectly. Does anyone know how I might be able to fix it?
My Java version is 8 update 101.
Had this issue with an associate at my company. The problem was that the .jnlp application was only trying to open in IE instead of the Javaws aplication.
What I did was right click on the file > Open with > Browse > C:\Program Files (x86)\Java\jre1.8.0_221\bin\javaws
I also marked a check by the box that said set this as default app. The issue no longer affects us
so it was the antivirus even after i turned it off it blocked the jnlp
and also it had been downgraded to a (free version) after the upgradeing to win 10 but after I reinstalled avast to the protection suit it worked again
locate the .jnlp file. right click and select "open with" ..then browse to a java program that will open it. I had this problem with marketcaster.jnlp with different browsers and this corrected it.
I had a problem opening a jnlp file, no matter what, trying to associate it with the Java Web Service exe javaws.exe, but it just would not associate and would not be run. I read throughout forums and all, and in the end from old DOS.exe files that I have used, somehow I did that and a miracle, it worked, I simply dragged the saved jnlp file and dropped it onto the javaws.exe, and it was executed. wanted to share this...
JRE 32 bit was causing issue for me . I uninstalled it and installed 64 bit JRE , JNLP files opened on all browsers. I think the browser n JRE must be both same 32 bit or 64 bit. Mismatch leads to this issue, not sure though.
