Struts comes with various related tools included in the struts-core-VERSION.jar file. You can access these tools by simply unpacking the Struts distribution and running
java -jar struts-core-VERSION.jar. Struts will automatically include all jars in the same directory as the struts-core-VERSION.jar file as well as all jars in the
lib directory. This means you can invoke these tools either from within the standard directory structure found in the Struts distribution, or from within your WEB-INF/lib directory.
You can access the help information for these tools by simply running the jar without any arguments.
