OutOfMemoryError: PermGen space

You can create a HibernateTemplate yourself. Simply inject the SessionFactory (as you do with the dao objects and inside the setter create a hibernatetemplate).

private HibernateTemplate hibernateTemplate;

public void setSessionFactory(SessionFactory sessionFactory) {
  hibernateTemplate = new HibernateTemplate(sessionFactory);
}

That should work or instead of the SessionFactory create a HibernateTemplate in your ApplicationContext.xml and inject that.

your suggestion make sense.
however, I'm still finding a place for injecting my sessionFactory. Could I just inject it inside my own LdapAuthenticationProvider. A portion of my config is:

<bean id="authenticationManager" class="org.acegisecurity.providers.ProviderManager">
	<property name="providers">
		<list>
			<ref local="ldapRoleAuthenticationProvider" />
		</list>
	</property>
</bean>
<bean id="ldapRoleAuthenticationProvider" class="com.fimat.security.util.LdapRoleAuthenticationProvider">
	<constructor-arg>
		<bean class="org.acegisecurity.providers.ldap.authenticator.BindAuthenticator">
			...
		</bean>
	</constructor-arg>
	<constructor-arg>
		<bean class="org.acegisecurity.providers.ldap.populator.DefaultLdapAuthoritiesPopulator">
			<constructor-arg>
				<ref local="initialDirContextFactory"/>
			</constructor-arg>
			<constructor-arg>
				...
			</constructor-arg>
			<property name="groupRoleAttribute">
				...
			</property>
		</bean>
	</constructor-arg>
</bean>

I try to embed the HibernateTemplate but find no way to inject the sessionFactory:

public class LdapRoleAuthenticationProvider extends LdapAuthenticationProvider{

	public LdapRoleAuthenticationProvider(LdapAuthenticator arg0, LdapAuthoritiesPopulator arg1) {
		super(arg0, arg1);
	}

	private HibernateTemplate hibernateTemplate;
	public void setSessionFactory(SessionFactory sessionFactory)
	{
		hibernateTemplate = new HibernateTemplate(sessionFactory);
	}
	public List getUserRoleList(String userID)
	{
		return hibernateTemplate.findByNamedQueryAndNamedParam("getRolesAuthenticated", "user_id", userID);
	}
}

Sorry for posting long code and appreciated for any suggestions.
