OptaPlanner Xml configuration and entitySubclass is not configured as a planning entity error -

-

i new optaplanner , having diffculty in configuring solution. have anotated of classes correctly getting following error when solver runs.

a planning entity instance of entitysubclass (class  org.optaplanner.core.impl.score.director.drools.droolsscoredirector) not  configured planning entity. if class (droolsscoredirector) (or superclass thereof) not entityclass  ([...part]), check solution implementation's annotated methods. if is, check solver configuration

here xml configuration using.

<?xml version="1.0" encoding="utf-8"?> <solver>     <solutionclass>(package name).sheetnesting</solutionclass>     <planningentityclass>(package name).part</planningentityclass>     <scoredirectorfactory>         <scoredefinitiontype>hard_soft</scoredefinitiontype>         <scoredrl>/resources/drools/nestingrules.drl</scoredrl>     </scoredirectorfactory>     <termination>         <maximumsecondsspend>500</maximumsecondsspend>     </termination>     <constructionheuristic>         <constructionheuristictype>first_fit_decreasing</constructionheuristictype>     </constructionheuristic>     <localsearch>     <unionmoveselector>       <changemoveselector>         <valueselector>           <variablename>sheet</variablename>         </valueselector>       </changemoveselector>       <movelistfactory>           <movelistfactoryclass>(package name).xposmovefactory</movelistfactoryclass>       </movelistfactory>       <movelistfactory>           <movelistfactoryclass>(package name).yposmovefactory</movelistfactoryclass>       </movelistfactory>     </unionmoveselector>     <acceptor>       <lateacceptancesize>600</lateacceptancesize>     </acceptor>     <forager>       <acceptedcountlimit>4</acceptedcountlimit>     </forager>   </localsearch> </solver>

the output shows solution establishes (possible evaluates phase(0) error thrown. appreciated.

*edit firstly thank comments. definition of part class follows

@planningentity(difficultycomparatorclass = partcomparator.class) public class part  {      ....     @planningvariable(valuerangeproviderrefs = {"sheetrange"})     public sheet getsheet()     {         ....     }       @planningvariable(valuerangeproviderrefs = {"xposrange"})     public double getxcenter()     {         ....     }      @planningvariable(valuerangeproviderrefs = {"yposrange"})     public double getycenter()     {         ....     } }

as can see class annotated, described. why believed issue configuration.

seems error it's telling (package name).part class not annotated @planningentity , @planningvariable described in documentation: http://docs.jboss.org/drools/release/6.0.1.final/optaplanner-docs/html_single/index.html#planningentity

if class correctly annotated please share in question.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
