I need your help in order to solve a question. I need to set the font size according to a value I stored into a session. I need to write something similar to
<a href="/chips" style="font-size: (#session.soglia)pt"><s:property value="nome"/></a>
but this does not work! How can I do? The font size is stored into a session because it can dinamically change (an action class calculates it before calling the jsp page). Thank you!!!

This does not explain why the session is needed here, but however...
to access a Session attribute, an Action attribute or whatever with OGNL, you need to use Struts Tags.
<a href="/chips" style="font-size: <s:property value='#session.soglia'/>pt">
<s:property value="nome"/>
</a>
Otherwise you'd need to use JSP EL. But don't.
Off-topic: it's worth noting that today we have more proficient ways to handle font sizes than points, eg. with Viewport Sized typography.
