Hi All,
I'm trying to return to set the value returned by a checkbox(whether checked or not) to a bean variable.However Imnot sure what the return type of the checkbox would be .
Is it boolean or String?
Thanks for helping.

All request parameters are strings. That's the way HTTP works.

Various frameworks, and tools like BeanUtils, can convert these strings to other types, but the submitted data itself is always a string.

You should note that standard HTML checkboxes will submit
- their value if they are checked (or ON if there is no value defined)
- no request parameter if they are unchecked.
