title: hibernate lazy initialization issue: LazyInitializationException: failed to lazily initialize a collection of role
body: <p>I want to manage a Transaction in my persistence layer,
  But when I try to fetch the results lazily I get this error:</p>
  
  <blockquote>
    <p>org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role</p>
  </blockquote>
  
  <p>Can I use LockMode or any other way to solve this problem?
  Can a find a Object by its id without any Transaction?</p>
