Create PDF in Struts from data on screen

Question

Hi,

I am able to create a simple pdf using iText api inside a struts action class.
The data that should be passed into the pdf is generated on screen based on user search parameters.
What I am wondering is how I can pass the data into the struts action so it can be displayed in the pdf?

Thanks in advance.

Similar question is already here. You just need to transfer everything that is on the page to struts action. I would do it like so:

JSP:

<div id="content">
  wrap everything generated in here
</div>
<html:hidden styleId="hiddenHtml" name="hiddenHtml"/>
<html:submit onclick="setContentAsParam();">Export PDF</html:submit>

JS:

function setContentAsParam() {
    document.getElementById('hiddenHtml').value = document.getElementById('content').innerHTML
}

This will set all the HTML to a action class property hiddenHtml. Get back if anything won't work, I wrote this out of my head without a test :)
