hibernate - Struts2 grid json -

-

how can exclude hibernate objects listed fetchtype.lazy? causes problems because org.hibernate.lazyinitializationexception. understand trying serialize object , can not because session closed. how can disable it? have many objects , not feasible make them eager nor remove them there many of them. please help.

i able use includeproperties suggested nmc, still nice not have define properties , see if jsonutil can ignore lazy loaded objects.

<result name="success" type="json">     <param name="includeproperties"> ^gridmodel\[\d+\]\.first, ^gridmodel\[\d+\]\.last, rows, page, total, record</param>                </result>
