I'm trying the WebWork2 and I follow the Quick Start Guide to do. The
program is successful to compile. But I found that the form parameter
didn't set to LoginAction. After I add the debug message. I found that
the variables, username and password, are null. hasErrors() is report
true. Pls advise and Thank you very much.

<ww:form name="'myForm'" action="'loginAction.action'" method="'post'">
<ww:textfield label="'username'" name="'username'"></ww:textfield>
<ww:password label="'password'" name="'password'"></ww:password>
<input type="submit" value="Login">
</ww:form>
<%@ include file="includes/footer.inc" %>
