  • Unable to load tag handler class "org.springframework.web.servlet.tags.form.For mTag "

    Hi all,

    I use Spring DM 1.2 with Spring MVC and try to use Spring tag library in my pages:

    <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

    ..snip..

    <form:form method="post" modelAttribute="user">
    ..snip..
    </form:form>

    ..snip..

    But i receive the following exception:
