So I´m trying to make an application with all http request get, put, post, delete.I'm making first a login with mysql and spring 3. So here I got this:
login.jsp:
<form:form id="myForm" method="post"
class="bs-example form-horizontal" commandName="UsersLogin">
signup.jsp
<form:form id="myForm" method="post"
class="bs-example form-horizontal" commandName="Users">
persistence.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="{http://java.sun.com/xml/ns/persistence} {http://java.sun.com/xml/ns/persistence_2_0.xsd}"

I got this error when trying to access to /login or /signup where I have my .jsp with my forms:
sep 24, 2015 11:14:35 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Allocate exception for servlet usersHibernateServlet
org.hibernate.hql.internal.ast.QuerySyntaxException: users is not mapped [SELECT s FROM users s WHERE s.userName = :userName]
I have been with this for two days, looking for answers here but no kind of good results from my side... just gives me the same error, any idea?
