There are at least three ways to create a SideEffect class (java file) that can be used as an option:

1. http://foo.smoslt.com/generating-sideeffect-classes/ – a wizard
2. same wizard as above, only run on your local box
3. Copy and paste an existing TemplateSideEffect.java file

Any are OK, but if you are willing to do number 1 above, your work product can be automagically shared with others
