i implemented an accumulate function which uses Datatypes, which i coded my
self , see example
the function return a list of ResourceMatch Objects, but when i try access
that objects i get an NullPointerrException (nothing more) (yes i imported
that class in the DRL)
so it seems that there has to be some kind of registration, so drools, can
handle these objectsm right ?
or what did i forget?
rule "Request counting analysed Resources By Id"
when
$list: List()
from accumulate($neu : RequestCtx() over
window:time(1m),countMatchingAnalysedResourcesInRequest($neu) )
ResourceMatch( $id: uri.toString(), count > 1 ) from $list
then
System.out.println( "Id " + $id + ": " );
System.out.println("Request counting Resources By Id Rule Workss");
channels["AuthZBlocking"].send(new ItemCacheEntry(new Item((String)$id),
new Date(System.currentTimeMillis()+ 8000)));
end

This uri.toString() looks suspicious. Try binding just uri and call
toString() in the consequence.

then
System.out.println( "Id " + $id + ": " );
System.out.println("Request counting Resources By Id Rule Workss");
