I upgrading hibernate3 to hibernate4 also i did all the changes but i am getting 'Could not retrieve pre-bound Hibernate session' exceptions in logs -

i upgrading hibernate4.3.11 using spring.4.0 in project.

i loading session factory , mapping resources extending localsessionfactorybean method buildsessionfactorymethod.

    @override         protected  sessionfactory buildsessionfactory(localsessionfactorybuilder localsessionfactorybuilder){             sessionfactory sessionfactory = null;             pmldialectmappings dialectmappings = null;              string[] mappingresources = null;             try {                  configuration configuration = new configuration();                             // building mappinglocations      configuration configuration = new configuration();                             // building mappinglocations                  dialectmappings =                         dialectmappingslocator.locatedialectmappings(configuration);                 if (dialectmappings != null) {                     setmappingresources(dialectmappings.getallmappingresources());                     abstractdao.setdialectsettings(dialectmappings);                 }          serviceregistry  builder =  new standardserviceregistrybuilder().applysettings(configuration.getproperties()).build();                 sessionfactory = configuration.buildsessionfactory(builder);      string schema = configuration.getproperty("hibernate.default_schema");               return super.buildsessionfactory(localsessionfactorybuilder); } 

is above code correct create sessionfactory? saw above way create session factory , loading mappingresources in same method. correct or not? in hibernate3 loading mapping resources in getconfiguration method. deprecated in hibernate4 thought load mappingresources in buildsessionfactory method only.

also in google got if add below property 'no hibernate session' error go didn't worked me. please give other suggestions.

hibernate.current_session_context_class=org.springframework.orm.hibernate4.springsessioncontext 

code in hibernate 3 build sessionfactory , load mappingresource

hibernate 4 changed cache regionfactory , change transanctionmanager hibernate 4.

i change above application context xml as

mainly need how create sessionfactory , how load mappingresources.

changed localsessionfactorybean code below. mapping resources loaded properly. previous in hibernate 3 configuration loading mappings before sessionfactorybean loads. in hiberate4 not that, have add resources manually localsessionfactory bean. same thing added it's worked. thought setmappingresources enough load need addresource localsessionfactory bean also.

dialectmappings = dialectmappingslocator.locatedialectmappings(configuration);  if (dialectmappings != null) {     setmappingresources(dialectmappings.getallmappingresources());     abstractdao.setdialectsettings(dialectmappings); }  for(string resource : dialectmappings.getparentdialectmappings().getallmappingresources()) {     configuration.addresource(resource); } 

after implemented proper nullsafeget , nullsafeset implemementaion, our project upgraded hibernate 4.3.11. able add query hints queries helps force indexing tables. stackoverflow help.
