Stop & restart Resin after any changes, and you shouldn't see this problem. Other Resin users may be able to elaborate on the best development setup.

Resin 2.1.6 (built Fri Nov 8 08:18:18 PST 2002)
and here is my login.jsp:
<%@ taglib uri="webwork" prefix="ww" %>
<%@ taglib uri="webwork" prefix="ui" %>
<div align="center">
<form action="<ww:url page="login.action"/>" method="POST">
<ww:if test="hasErrorMessages == true">
ERROR:<BR>
<ww:iterator value="errorMessages">
<FONT COLOR=red><ww:property/></FONT><BR>
</ww:iterator>
</ww:if>
<table border="0">
<tr>
<td>Username:</td>
<td><input type="input" name="username"></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="input" name="password"></td>
</tr>
<tr>
<td colspan="2">
<input type="Submit" name="Login">
</td>
</tr>
</table>
</form>
</div>
I am accessing this page as the result of an action (i.e. Click <a href='<ww:url page="/viewlogin.action"/>'>here</a> to login)
I think I must be missing a configuration element or something. Any help would be appreciated.
Thanks
Todd
