Hi,
I have a GWT RPC method as follows :
public String validate(ApplicationData ad) {
Object dataObj = null;
KnowledgeAgent kagent =
(KnowledgeAgent)getServletContext().getAttribute("KNOWLEDGE_AGENT");
KnowledgeBase kbase = kagent.getKnowledgeBase();
StatefulKnowledgeSession sf =
kbase.newStatefulKnowledgeSession();
FactType ft = kbase.getFactType("axaPMTPOCPackage",
"ApplicationData");
try {
dataObj = ft.newInstance();
ft.set(dataObj, "name", ad.getName());
ft.set(dataObj, "sex", ad.getSex());
ft.set(dataObj, "minIssrdAge", ad.getMinIssrdAge());
ft.set(dataObj, "age", ad.getAge());
ft.set(dataObj, "boxname", ad.getBoxname());
sf.insert(dataObj);
RuleNameStartsWithAgendaFilter filter = new
RuleNameStartsWithAgendaFilter(ad.getRuleName());
sf.fireAllRules(filter);
sf.dispose();
} catch(Exception e) {
e.printStackTrace();
}
String returnMsg = (String)ft.get(dataObj, "returnMsg");
return returnMsg;
}
At the client side, I made 2000 times of the above ajax call to
validate 2000 fields.
However, I got the following java exception after making certain
number of calls.
