As you have suggested I have updated my jsp as shown below-
BUT NOW it gives me error "No getter method for property username of bean
org.apache.struts.taglib.html.BEAN".. i think it tries to find the
getUsername and getPassword.. And in my ActionForm bean has only getValue
and setValue functions...How do i deal with this now?

The jsp you're using for this example should contain the struts
taglibs and
should look like this
<html:form action="/login">
Login <html:text property="login"/>
Password: <html:password property="password"/>
</html:form>
