I get the following error with trying to execute a for loop that retrieves different items with collections of FileReference collections inside a Wildfly Container using the EntityManager.
@JsonIgnoreProperties(ignoreUnknown = true)
@Entity
public class Item {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Type(type="objectid")
private String id;
private String itemName;
private String itemDescription;
private Date dateManufactured;
private Long bggId;
private String bggType;
@Transient
private List<String> imageUrls;
@Transient
private String condition;
public String getCondition() { return condition; }
public void setCondition(String condition) { this.condition = condition; }
public List<String> getImageUrls() { return imageUrls; }
public void setImageUrls(List<String> imageUrls) { this.imageUrls = imageUrls; }
public String getBggType() { return bggType; }
public void setBggType(String bggType) { this.bggType = bggType; }
public Long getBggId() { return bggId; }
public void setBggId(Long bggId) { this.bggId = bggId; }
@OneToMany(fetch=FetchType.EAGER)
private List<FileReference> fileReferences;
public List<FileReference> getFileReferences() { return fileReferences; }
public void setFileReferences(List<FileReference> fileReferences) { this.fileReferences = fileReferences; }
public String getItemName() { return itemName; }
public void setItemName(String itemName) { this.itemName = itemName; }
public String getItemDescription() { return itemDescription; }
public void setItemDescription(String itemDescription) { this.itemDescription = itemDescription; }
public Date getDateManufactured() { return dateManufactured; }
public void setDateManufactured(Date dateManufactured) { this.dateManufactured = dateManufactured; }
public String getId() { return id; }
public void setId(String id) { this.id = id; }
