In JavaSE Project when WebStart is enabled, the Run with Java WebStart checkbox in Project Properties Run panel is enabled and can be checked/unchecked, but its state does not persist when OK is pressed. Currently this does not affect usability of WebStart with JavaSE projects because there exists a WebStart configuration where WS is enabled; the only nuisance would be if for some reason users wanted to disable WS in the WebStart category or enable WS in the default category.

Quote on bug 229236: ----------------------------------------------- fatbuttlarry 2014-04-10 02:15:43 UTC This is common enough actually. The combination of NetBeans and Ubuntu seems to cause this. I've reproduced on NetBeans 7.4 + OpenJDK7 x86_64, NetBeans 8.0 + OpenJDK7 x86_64. This completely breaks WebStart functionality on Ubuntu. Any work-arounds would be appreciated as this forces some of my projects to be built on another OS (Windows) until this is resolved. ----------------------------------------------- This problem is also present on mu Ubuntu 14.04 LTS system.
Bug still present in Ubuntu 15.10: Product Version: NetBeans IDE 8.0.2 (Build 20150619-debian-8.0.2) Java: 1.7.0_85; OpenJDK 64-Bit Server VM 24.85-b03 Runtime: OpenJDK Runtime Environment 1.7.0_85-b01 System: Linux version 4.2.0-16-generic running on amd64; UTF-8; en_US (nb) and I also agree that it makes it very difficult to work. Using the Web Start configuration does not help Workaround: Files->NBProject->project.properties; manually set jnlp.enabled=true; save file, rebuild, then do it all over again whenever the gui is restarted or project web start properties inspected)
I had the same problem with Netbeans 8.1 on FreeBSD. So i have icedtea-web instead of oracle-webstart just like Ubuntu. I use the following workaround. make the following link in the openjdk/jre/lib-directory javaws.jar -> /usr/local/share/icedtea-web/netx.jar and set manifest.custom.application.library.allowable.codebase=* in nbproject/project.properties
lhersch's workaround worked for me! Using Ubuntu 18.10; Apache NetBeans IDE 11.0 (Build incubator-netbeans-release-404-on-20190319); openjdk version "11.0.3" 2019-04-16; OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu218.10.1) I did: cd /usr/lib/jvm/java-11-openjdk-amd64/lib sudo ln -s /usr/share/icedtea-web/javaws.jar
