    Default Unclosed Hibernate Connection

    i just isntalled acegi yesterday, and now i have been noticing Hibernate log entries that say "Unclosed Connection". Anybody else seen this before? As a result of this (I assume), HTTP request begin to stall (freezing) during a query for the user account (its a hibernate DAO query).

    I am using spring 1.1, hibernate 2.1.6, acegi 0.8.1.

    Here is a snipet from my log where it shows a WARN log message that there was an unclosed session.

    Code:
    [DEBUG][net.sf.acegisecurity.intercept.AbstractSecurityInterceptor] - Authenticated: net.sf.acegisecurity.providers.UsernamePasswordAuthenticationToken@f3d040: Username: com.ccg.domain.Account@3b5d6b[id=1,u....security.Group@1e668b2[id=1,name=Users,description=Intranet Application User,roles=[com.ccg.security.Role@1523624]]]]; Password: [PROTECTED]; Authenticated: true; Details: net.sf.acegisecurity.ui.WebAuthenticationDetails@1aa38c7: RemoteIpAddress: 127.0.0.1; SessionId: 5E2D43C38FC1C20DC88CFE0C69121D19; Granted Authorities: ROLE_USER

    The hibernate unclosed connection warning appears at almost every query via hibernate, however, it seems to start when the first call to loadUserByName() which in turn is calling this method:

    Code:
        public Account getAccountByName(String name) throws DataAccessException {
    	Account account = null;
        try {
            account = (Account)getSession()
            	.createQuery("FROM Account a WHERE a.username = :name")
            	.setParameter("name", name)
            	.uniqueResult();

        } catch (net.sf.hibernate.HibernateException ex) {
            throw SessionFactoryUtils.convertHibernateAccessException(ex);
        }
        return account;
    }
    I know this might seem like a hibernate question, but these problems never came up before I added Acegi. This method was actually being used by a mock security module we had in place for the time being.

    Acegi Security doesn't do anything with Hibernate at all. It delegates all persistence-related interactions to the AuthenticationDao, which you usually write (or use JdbcDaoImpl or InMemoryDaoImpl). I personally use Hibernate in many applications quite successfully with Acegi Security, and I know many others do as well. For these reasons this sounds to me more like a Hibernate question.

    I am curious whether you're using OpenSessionInViewFilter with Hibernate. If so, perhaps the fact the AuthenticationDao is accessing Hibernate from an Acegi Security filter (probably AuthenticationProcessingFilter or FilterSecurityInterceptor) is the issue. Is your OpenSessionInViewFilter being executed before these Acegi Security fitlers?

    I checked our code, we are using the OpenSessionInViewFilter. It is, however, defined as a bean in applicationContext.xml. I replaced the bean def with a filter in web.xml and I am testing it out right now. I have not come across any unclosed session warnings yet, but i am having other strange errors that I have to work out. I'll keep at it for a while, im sure by removing the OpenSessionInView bean, some DAO's are no longer happy campers.

    Thanks for the tip Ben, I appreciate your help.


    edit: sorry, i meant we were using OpenSessionInViewInteceptor (thats why it was defined as a bean)

    Looks like the unclosed session problem is fixed. My web.xml looks like so... is the ordering correct? Some requests are throwing the exception shown below. I read on the spring api docs that errors like this may appear after adding the OpenSessionInViewFilter, not sure how to fix it.

    edit: in addition to the errors shown below, i am also getting exceptions telling me that i am in read only mode and that i need to set my flush mode to AUTO. I can't find anywhere in the API docs that allows me to set flush modes on the OpenSessionInViewFilter. Where do i configure this property if its not a property of the filter object?

    Code:
    	<!-- Keep the hibernate sessions open in the view -->
	<filter>
		<filter-name>Hibernate View Session Filter</filter-name>
		<filter-class>
			org.springframework.orm.hibernate.support.OpenSessionInViewFilter
		</filter-class>
	</filter>	
	<filter-mapping>
		<filter-name>Hibernate View Session Filter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

<!--
