yep, it's simple.
Up in the <%@Page... just add this -> validateRequest="false"
HOWEVER, you do need to realise why this setting restricts you in default.
Basically, if you allow someone to include there own html tags in a given text
eg: <b>Words</b>... there's nothing to stop them from doing this
If you wanted to then display it to the screen, you can encode and decode the text to make it display without doing any bad stuff.
