AJAX saving in struts2

[Rahul Solanki]

I am using Struts2 and ajax to save code.

<s:form action="saveData">
         <textarea id="LineComments" name="LineComments"></textarea>

          <s:submit type="button" theme="ajax" label="Update Content"/>
</s:form>

Struts.xls
<action name="saveData" class="dataAction" method="saveComment">
<result name="success">mycomment.jsp</result>
</action>

Here the page gets reloaded which should not happen in ajax. I am new to struts2 and ajax please let me know if I am missing something or passing some wrong parameter in struts.xml.

Thanks.
Rahul
