2. JActor Getting Started Basic Code Samples State Machines 3. Getting Started The JActor jar file Create a test environment 4. The JActor jar file Download Jactor-3.1.0.zip fromhttps://sourceforge.net/projects/jactor/files/ Extract jactor-3.1.0.jar from the zip file and copyit to a new directory, GettingStarted. (The JActor version will changecurrentversion is 3.1.0.) 5. Create a Test Environment Create a j.bat file in the GettingStarteddirectory: del *.class call javac -classpath jactor-3.1.0.jar *.java call java -classpath .;jactor-3.1.0.jar GettingStarted The j.bat file can be used to run a test. 6.
