struts2jquery sending parameters to action

[James Peter]

Hi All,

My requirement is to send 2 parameters to remote url. One created dynamically and another from Form text field like specified in below code. I am getting parameter value of studentName in action but getting null value for studentSubject. Both are having getters and setters in action. Please let me know what is wrong in my code.

  <s:form id="formSelectOne" action="echo" theme="simple" cssClass="yform">
        <fieldset>
            <legend>AJAX Form populated by a String List</legend>
	        <div class="type-text">
	            <label for="echo">Echo: </label>
				<s:url id="remoteurl" action="jsonsample" escapeAmp="false">
					<s:param name="studentName">Peter</s:param>
				</s:url>
				<sj:select 
					href="%{remoteurl}" 
					id="echo" 
					name="echo" 
					list="languageList" 
					emptyOption="true" 
					headerKey="-1" 
					headerValue="Please Select a Language"
					required="true"
					formIds="formSelectOne"
					parentTheme="KUTheme"
				/>
	        </div>
	        <div class="type-button">
				<sj:submit 
					targets="result1" 
					value="AJAX Submit" 
					indicator="indicator" 
					button="true"
				/>
				<img id="indicator" src="images/indicator.gif" alt="Loading..." style="display:none"/>
	        </div>
        </fieldset>
        <s:textfield name="studenSubject" value="Science"></s:textfield>
    </s:form>

Thanks
Peter
