ArrayList Mapping
Hi,
I have an Object Rollingstock, inside Rollingstock I have a collection off Vehicles.
Hear is the mapping:
@JoinTable( name="vehicles",
joinColumns= @JoinColumn( name= "fk_rollingstock"),
inverseJoinColumns= @JoinColumn( name="id_vehicle") )
public Collection<Vehicle> getVehicles() { return vehicles; }
public void setVehicles(ArrayList<Vehicle> vehicles) { this.vehicles = vehicles;}
when i try to persist an Roolingstock i get this error:
19:41:54,218 ERROR [property.BasicPropertyAccessor] expected type: java.util.ArrayList, actual value: org.hibernate.collection.Pe rsistentBag 19:41:54,234 ERROR [er.jms.inflow.JmsServerSession] Unexpected error delivering message delegator->JBossMessage[376834]:PERSISTEN T, deliveryId=1 javax.ejb.EJBTransactionRolledbackException: org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calli ng setter of se.sj.ipl.rollingstock.domain.Rollingstock.vehicles at org.jboss.ejb3.tx.Ejb3TxPolicy.handleInCallerTx(Ejb3TxPolicy.java:87) at org.jboss.aspects.tx.TxPolicy.invokeInCallerTx(TxPolicy.java:130) at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:195) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:76) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:62) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.remoting.ReplicantsManagerInterceptor.invoke(ReplicantsManagerInterceptor.java:51) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.security.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:77) at org.jboss.ejb3.security.Ejb3AuthenticationInterceptor.invoke(Ejb3AuthenticationInterceptor.java:106) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.ENCPropagationInterceptor.invoke(ENCPropagationInterceptor.java:46) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.asynchronous.AsynchronousInterceptor.invoke(AsynchronousInterceptor.java:106) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessContainer.dynamicInvoke(StatelessContainer.java:278) at org.jboss.ejb3.remoting.IsLocalInterceptor.invokeLocal(IsLocalInterceptor.java:79) at org.jboss.ejb3.remoting.ClusteredIsLocalInterceptor.invoke(ClusteredIsLocalInterceptor.java:53) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessClusteredProxy.invoke(StatelessClusteredProxy.java:105) at $Proxy158.persistRollingStock(Unknown Source)
