Parameters to s:url action call

[Joe Harry]

Guys,

I have a jsp page which has an anchor tag rendered through the use of s:url tag as below:

	<a class='tab-loader' href="<s:url action='startExam' namespace="/content"/><s:param name="/attr/" value="/player"/>">Java Test 2</a> : Focus on Constructor and Object creation</br></br>

In my action class i get to see the attr as null. My action class is ModelDriven. Is the way I have defined my s:url is correct?
