Executing jar file with file name as argument

Question

I have created a JAVA application to get the IMDB ratings of movies. The application takes one command line argument (name of the movie) and displays the rating of the same. I have added the application to the right-click context menu. so, now when I right click I need the file name (without extension) to be passed as a command line argument. How can I do this?

I tried adding %1 as placeholder in the registry but it doesn't seem to work. The application works from the command line with an argument.

Can someone help me?

COMMAND LINE:

java -jar C:\NetBeansProjects\APPLICATION\dist\APPLICATION.jar daredevil

OUTPUT:

RIGHT CLICK MENU

Well what do you receive in your java program? What's causing the NPE? — JP Moresmau, Mar 03 '16 at 17:51
The name of the movie is received as a command line argument. Whn I right click on a file, the name of the file is suppossed to be received but that is not being received I guess, which causes the NPE. — Jithin Gangadharan, Mar 03 '16 at 17:54
Yes I understand that. Modify your program to dump the value of the argument you actually receive, to ensure the issue is really in passing the argument. What would passing a wrong argument cause a NPE? — JP Moresmau, Mar 03 '16 at 17:55

put your jar file in your jre/lib/ext folder then compile your program without -jar Option.

Everything said about the classpath is true, but this is a consistent and sensible place for it to live.

you can find out your jre folder by looking at the JAVA_HOME environment variable on Windows.
