I create a project.
I can use designer to launch project and run it normally but i download project suffix
‘.jnlp’ file to run.
It display JAVA icon. Several minutes later the icon disappear.
Nothing happened.
The project didn’t luanch successfully.
What’s this all about?
The problem has been resolved.
java version select wrong. 
While you may have resolved the problem in the short term, you should know that Ignition v8.x requires newer versions of java that do not support JNLP files at all. Start learning to use the native launchers before v7.9 reaches end-of-life next summer.
OK Thanks
