Anyone know what this means?? How can I change the pre-configured STRICT
strategy :
net.sf.json.util.CycleDetectionStrategy$StrictCycleDetectionStrategy to
LENIENT ?? and will that even help me here?
Using Hibernate 3.1 with Struts 2.1.3 and the REST plugin. XML serializaion
works fine after changing Hiberbate lazy loading to FALSE...
