Hello
I'm using the dvd-example and I tried to create two EntityBeans like Order and
OrderLine with a OneToMany Relationship.
anonymous wrote :
| @Entity
| @Name(bpath)
| @Scope(EVENT)
| public class Path implements Serializable{
|
| private int pathId;
| private String pathName;
| private List pathTerms = new ArrayList ();
|
| @Id @GeneratedValue
| @Column(name=PATHID)
| public int getPathId() {
| return pathId;
| }
| public void setPathId(int pathId) {
| this.pathId = pathId;
| }
|
| @NotNull
| public String getPathName() {
| return pathName;
| }
| public void setPathName(String pathName) {
| this.pathName = pathName;
| }
|
| @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy
=referPath)
| @JoinColumn (name = PATHID)
| public List getPathTerms() {
| return pathTerms;
| }
| public void setPathTerms(List pathTerms) {
| this.pathTerms = pathTerms;
| }
|
|
| public void addPathTerm(String text) {
| if (pathTerms == null)
| pathTerms = new ArrayList();
|
| PathTerm pathTerm = new PathTerm();
| pathTerm.setText(text);
| pathTerm.setReferPath(this);
|
| pathTerms.add(pathTerm);
| }
|
| }
anonymous wrote :
| @Entity
| @Name(pathterm)

|
| int pathTermId;
| int frequency;
| int totalNumber;
| String text;
| String dfrequency;
| Path referPath;
|
|
| @Id @GeneratedValue
| @Column(name=PATHTERMID)
| public int getPathTermId() {
| return pathTermId;
| }
| public void setPathTermId(int pathTermId) {
| this.pathTermId = pathTermId;
| }
|
|
| public String getDfrequency() {
| return dfrequency;
| }
| public void setDfrequency(String dfrequency) {
| this.dfrequency = dfrequency;
| }
|
|
| public int getFrequency() {
| return frequency;
| }
| public void setFrequency(int frequency) {
| this.frequency = frequency;
| }
|
|
| @ManyToOne
| @JoinColumn (name = PATHID)
| public Path getReferPath() {
| return referPath;
| }
| public void setReferPath(Path referPath) {
| this.referPath = referPath;
| }
|
| public int getTotalNumber() {
| return totalNumber;
| }
| public void setTotalNumber(int totalNumber) {
| this.totalNumber = totalNumber;
| }
| public String getText() {
| return text;
| }
| public void setText(String text) {
| this.text = text;
| }
|
| }
|
|
Furthermore I use the import file with these two statements
anonymous wrote : insert into PATH (PATHID, PATHNAME) VALUES (1, 'PATH 1')
| insert into PATHTERM (PATHTERMID, PATHID, TEXT, FREQUENCY, DFREQUENCY,
TOTALNUMBER) VALUES (1, 1, 'myText', 2, 'anotherText', 3)
I get this exception and have no idea, what's wrong
