Description Petr Somol 2012-03-22 10:34:28 UTC
On Mac with JDK 7u4 it is not possible to run a Java/JavaFX project using WebStart technology. Run fails because webstart executable is not found.
Comment 1 Petr Somol 2012-03-22 10:52:18 UTC
The issue is caused by a problem outside NetBeans. JDK 7u4 indeed does not support WebStart technology. However, WebStart support should appear in next upcoming Mac JDK 7 updates.

If a NetBeans Java/JavaFX project is set to run as WebStart on Mac JDK 7u4 in NetBeans 7.1 or 7.1.1, the run operation simply fails. NetBeans 7.1.2 and 7.2 on Mac JDK 7u4 additionally write out a message explaining that WebStart is not supported on Mac JDK 7u4. The build process is not affected and produces WebStart related artifacts (JNLP file) as expected.
Comment 2 Petr Somol 2012-03-22 13:19:37 UTC
Remark: MacJDK7u4 detection and warning has been added to FX build scripts as part of issue 208798:
