java - mappedBy reference an unknown target entity property with inheritance -


i trying store entity inside database hibernate. have got following classes:

@entity public class usableremoteexperiment extends remoteexperiment { private list<experimentnodegroup> nodegroups = new arraylist<>();   @onetomany(mappedby = "experiment", cascade = cascadetype.all, orphanremoval = true) public list<experimentnodegroup> getnodegroups() {     return nodegroups; }  public void setnodegroups(final list<experimentnodegroup> nodegroups) {     this.nodegroups = nodegroups; } /* more getters , setters other attributes */

the experiment node group looks this:

@entity public class experimentnodegroup extends nodegroup {  private list<node> nodes = new arraylist<>(); /* more getters , setters other attributes */

and nodegroup class looks this:

@entity public abstract class nodegroup extends generatedidentity { protected experiment experiment;  @manytoone(optional = false) @jsonignore public experiment getexperiment() {     return experiment; } /* more getters , setters other attributes */

now when try compile code, error:

caused by: org.hibernate.annotationexception: mappedby reference unknown target entity property: [...].experimentnodegroup.experiment in [...].usableremoteexperiment.nodegroups

it's 1 of quirks of hibernate not work expected mappedby , inheritance. try specifying targetentity well? here's documentation , says:

the entity class target of association. optional if collection property defined using java generics. must specified otherwise.

you can try specifying targetentity = experimentnodegroup.class or targetentity = transaction.class , see if makes difference.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
