Problem regarding query string in struts

hello friends...

I am new to struts i want to implement a small code to add,modify,view and delete employee.For that i have made index.jsp
.index.jsp looks like :-

<%@ taglib uri="/WEB-INF/lib/struts-html.tld" prefix="html" %>

<html>
<head><title>Employee Management</title></head>
<body>
<table cellspacing="0" cellpadding="0" align="center">
<tr>
<td>
<html:link href='index.jsp?activity=add'>Add New Employee</html:link> |
<html:link href='index.jsp?activity=modify'>Modify Employee Details</html:link> |
<html:link href='index.jsp?activity=view'>View Employee Details</html:link>|
<html:link href='index.jsp?activity=delete'>Delete Employees</html:link>
</td>
</tr>
</table>
</body>
</html>

Now i want to display the forms for each addition,modification and deleteion in the index.jsp only but i dont want to use scriplets in my index.jsp.Can anyone suggest me the way how to implement this .

Thanks

This is not very clear. If you just want to do some conditional work in your JSP on the basis of a request parameter, then use Struts Logic Tags or JSTL (mainly the Core JSTL Tags)...

I dont want to get the value of activity through request parameter in my jsp.Is there any other way ?

So you mean you don't want to pass the activity as a request parameter when you make the request or don't want to retrieve the request parameter??
