Hi all,
Please forgive this newbie post - I have searched the forum and the
tutorials/specification for an answer without success. I'm sure the solution
must be something simple.
I'm trying to make an entity that has a collection of objects as one of it's
attributes:
package ch.adamcc.planeres2.entity;
|
| import java.util.ArrayList;
| import java.util.List;
|
| import javax.persistence.Entity;
| import javax.persistence.Id;
|
| @Entity
| public class SimpleEntity {
| private long _id;
| private String _stringField;
| private List<String> _stringList;
| private long[] _longArray;
|
| public SimpleEntity()
| {
| _stringList = new ArrayList<String>();
| _longArray = new long[2];
| }
|
| @Id
| public long getId() {
| return _id;
| }
|
| public void setId(long id) {
| _id = id;
| }
|
| public String getStringField() {
| return _stringField;
| }
|
| public void setStringField(String stringField) {
| _stringField = stringField;
| }
|
| public List<String> getStringList() {
| return _stringList;
| }
|
| public void setStringList(List<String> stringList) {
| _stringList = stringList;
| }
|
| public long[] getLongArray() {
| return _longArray;
| }
|
| public void setLongArray(long[] longArray) {
| _longArray = longArray;
| }
| }
When I deploy the entity I get the following exception:
2006-10-11 15:02:47,115 WARN [org.jboss.system.ServiceController] Problem

As far as I can tell I have followed the specification, but the documentation
seems to be a little vague on how to do this and I couldn't find any examples
to follow. I did try various variations on the same theme, without success.
I would very much appreciate a hint on what I am doing wrong.
Thanks very much in advance for your help.
Yours,
Adam.
