Nella mia applicazione, ho un modulo che è progettato per cercare un database per gli utenti e visualizzare le loro informazioni in una tabella all'interno di un jsp. Ho appena installato Spring Security all'interno della mia applicazione. Sono stato in grado di stabilire una connessione con il database dalla pagina di accesso, sebbene per qualche motivo nessuna delle operazioni CRUD del mio DAO (in questo caso, la ricerca) funzioni.Impossibile aprire Hibernate Session per transazione/Impossibile aprire la connessione
Grazie, e per favore fatemi sapere se posso fornire ulteriori informazioni.
Ecco la maggior parte della traccia dello stack.

può tagliare questo fino a che solo le sezioni pertinenti? Questo è troppo lungo per avere una buona possibilità di attirare l'attenzione. Vedi http://sscce.org/ – tacaswell
Ho rimosso il LoginController e il contesto di sicurezza. Nella stessa nota, l'eccezione stesso deriva dal SearchUserController su questa linea: ** = listaRicerca userInfoDao.searchEntity (search.getInput()); ** – AndyAdamantium
è ' url ' l'URL del server corretto?!? –
