How to get a running Jar's file path?

Question

When I run some jar file, the process created is an instance of the JVM, which executes the jar. How can I know what jar file a JVM process is running? I would like to use this information to retrieve said jar's file path.

Answer 1

Invoke the JAR by using the full path as the -jar parameter from the command line. The Task Manager can show the command line which includes the path to the JAR. Open it by running taskmgr from Windows search. Then do one of the following:

1. In the Processes tab, right-click the column header and enable the Command Line option.

OR

2. In the Details tab, right-click the column header, click Select Columns, click the Command Line checkbox, and click OK.
