title: spring hibernate manual commit
body: <p>can somebody help for this?</p>
  
  <p>currently i met some problems, i am using spring,jpa,hibernate.
  here is the problem, when i try to save several objects, and then manually roll back as when solrj return false.</p>
  
  <p>i tried the following:
  <br>1. usertransaction (exception: <code>Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException</code>)</p>
  
  <p>2.<code>entitymanager.gettransaction().begin</code>(exception: shared manager)</p>
  
  <p>thanks, if you can help me to figure out.</p>

          em.getTransaction().begin();// ***error occur on here*** and stop here
          //...............proccess
          boolean ok = SolrJ.IndexingWallPost(solrURL,userid, wallPost.getTitle(), wallPost.getMessage(), hashtag,groupsid);
          if(!ok)
              em.getTransaction().rollback();
  
  
  
          em.getTransaction().commit();
          return true;
      }
