#23020 — Getting path to jar passed on command line

Is there a way to get the path of the jar file that was passed on the command line?

java -jar <some path>

You could try

RuntimeMXBean rtmxb = ManagementFactory.getRuntimeMXBean();
List<String> inArgs = rtmxb.getInputArguments();

although the documentation seems to suggest that what is actually
passed to the Runtime bean is dependent on the particular implementation 
of the jvm you happen to be using.

He could try it.

But I think he will have better luck with rtmxb.getClassPath().

Given how many different ways there are to get your code
activated (java -jar, java -cp, wrapper main), then my
recommendation would be:

NameOfYourClass.class.getProtectionDomain().getCodeSource().getLocation().getPath()

as this will locate where that class is being loaded from no matter
how it gets activated.

http://stackoverflow.com/questions/320542/how-to-get-the-path-of-a-running-jar-file

Gives some good advice

The solution

String path = 
Test.class.getProtectionDomain().getCodeSource().getLocation().getPath();
		String decodedPath = URLDecoder.decode(path, "UTF-8");

Works for me and gives me the path to the jar file containing the class 
that contains the above code.

You can use -cp to specify the classpath or fully qualify the jar
name.

Is that relevant for the question?
