How do I find out if a specific JAR file is running on my machine or not? I just want to ensure that a specific JAR is only executed once at any time-- so if another request to execute the same jar comes in then I should not again invoke that jar. I can use code for the above either as java code (which I will add to that JAR itself) or as shellscript (which I will use to invoke the jar file). The machine will be a Linux machine-- either CentOS, or Debian or Ubuntu or Amazon Linux. jps is a simple command-line tool that prints out the currently running JVMs and what they're running. You can

I'm creating a Java applet from a large scale pre-existing project (Vizster). I am using NetBeans 6.7.1 with JDK 1.5 on Mac OS X. I am attempting to run the applet from it's single output .jar file, but when I do this, it says "applet loaded" at the bottom of screen in Firefox, and there is nothing in the java console, but nothing shows up in the window for the applet.

Ultimately, I would like to include an additional library which I wrote with the jar, but at the moment I am just trying to package a simple program and have it run from the jar. I have tried following the jar instructions in the "Using the Jar Method" section here: Jython FAQ: Using the Jar Method I have also looked at slides 25-28 here: Jython Update 2012 slides And finally here: stackoverflow Question: Distributing My Python Scripts as Jars

I want to make a executable file of my project which I made in Java fx 2.0. Can anyone help me on this? The JavaFX team implemented support for this in the tools bundled with the JavaFX 2.2 SDK (included in Java7 from update 6). The JavaFX packaging toolset for packaging executables is documented in self-contained application section of the JavaFX deployment guide. See RT-19446 "Add ability to co-bundle Java + JavaFX + App into a single native executable" for more information (anybody can sign up to view the jira). 3rd party tools such as the JavaFX maven plugin or the JavaFX gradle plugin ,
