hi matt, i sorted out the problem as it was not of ram memory but of setting property lazy="false" in my .hbm.xml files in many places as it was done to get the associated records without doing extra wrok. So when the action was called the hibernate was executing all queries till the last hiearchy for each object for which lazy="false" was given in .hbm.xml file, So there were lots of lots of quires fired just for a simple action.
so how can i get this functionality programitcally at runtime so that only associated object is retrived rather than retriving all its child records. how can i lazy initialize at runtime On Wed, Sep 16, 2009 at 4:57 PM, Matt Raible <m...@raibledesigns.com> wrote: > What do you have your memory settings at?
