Keyword: struts2 preparable, spring OpenSessionInViewFilter, hibernate transaction management.
Background: We use OpenSessionInViewFilter in our web xml to enable lazy loading in web views. The struts action class provides a basic function in adding, updating and deleting data entity as a controller. Our form fields reference the entity object and its properties with a valid OGNL expression... like <s:textfield name="organisation.phoneNumber"></s:textfield> The submitform's action does nothing to D.B. Problem: Case A: The struts action does not implement Preparable interface and we use some private method to initialize the data used . The jsp uses the entity expression directly. <s:textfield name="organisation.phoneNumber"></s:textfield> As a result, whenever you make any change in the jsp for this entity and submit the form, it does not go to the D.B. Which is good because this is exactly what we want as “Open Session in View”, which is read-only. Case B: The struts action does implement Preparable interface and in the implementation, we retrieve the data from database and populate its original value. And the jsp uses the entity expression directly. <s:textfield name="organisation.phoneNumber"></s:textfield> As a result, whenever you make any change in the jsp for this entity and submit the form, it changes the D.B. My question is the case B: How does "Preparable" influence hibernate transaction management? Anyone has any idea? I guess it is related to the struts 2 Interceptor, which does have some influence to the spring, which then influences the hibernate transaction control. I post the problem in struts forum, not spring or hibernate forum, because if I do not use "Preparable", everything works as expected. cheers Jack -- View this message in context: http://www.nabble.com/%22Preparable%22-influence-hibernate-transaction-management-when-using-%22OpenSessionInViewFilter%22-tp19660675p19660675.html Sent from the Struts - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
