[JBoss-user] [EJB 3.0] - @ManyToOne or @OneToOne using @JoinTable and @Inheritance ca
I have experence a problem while mapping a legacy database when I am attempt to
use @ManyToOne using @JoinTable and the parent class is declaired with
@Inheritance(strategy=InheritanceType.JOINED). Here is a simplified version of
what I am attempting:
@Entity
| @Inheritance(strategy=InheritanceType.JOINED)
| @Table(name = baseclass)
| public abstract class Baseclass implements java.io.Serializable {
|
| private String internalid;
|
| @Id
| @Column(name = INTERNALID, unique = true, nullable = false,
insertable = true, updatable = true, length = 34)
| public String getInternalid() {
| return this.internalid;
| }
| public void setInternalid(String internalid) {
| this.internalid = internalid;
| }
| }
@Entity
| @Table(name = parent)
| public class Parent extends Baseclass
| {
|
| private String name;
|
| public String getName(){
| return this.name;
| }
| public void setName(String name){
| this.name = name;
| }
| }
@Entity
| @Table(name = child)
| public class Child implements java.io.Serializable {
|
| private String internalid;
| private String name;
| private Parent parent;
|
| @Id
| @Column(name = INTERNALID, unique = true, nullable = false,
insertable = true, updatable = true, length = 34)
| public String getInternalid() {
| return this.internalid;
| }
| public void setInternalid(String internalid) {
| this.internalid = internalid;
| }
|
| public String getName(){
| return this.name;
| }
| public void setName(String name){
| this.name = name;
| }
|
| @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE})
| @JoinTable(name=hierarchy,
| joinColumns = @JoinColumn( name=childinternalid),
| inverseJoinColumns = @JoinColumn( name=parentinternalid))
| public Parent getParent(){
| return this.parent;
| }
| public void setParent(Parent parent){
| this.parent = parent;
| }
| }
When I try this in JBOSSAS4.0.4GA I receive the following error:

If I switch the association to @OneToMany on the parent side there is no error.
I have also experenced this same error using bidirectional @OneToOne with an
association table where either end is using
@Inheritance(strategy=InheritanceType.JOINED), and if I make it unidirectional
on the end without @Inheritance(strategy=InheritanceType.JOINED) it does not
throw the error.
I'm not sure what I am doing incorrectly.

[JBoss-user] [JBoss Seam] - Re: Portal example errors with 4.0.4CR2 and Portal 2.4
I was able to get the portlet example to work using JBossAS 4.0.4CR2, JBoss Portal 2.2.1, and jboss-seam-1.0.0.CR2 by with following: Install JBossAS 4.0.4CR2 with the installer, selecting EJB Copy jboss-portal.sar and portal-hsqldb-ds.xml from the binary download of JBoss Portal 2.2.1 into jboss-4.0.4.CR2\server\default Modify the jboss-service.xml per: DViper01 wrote : I just had the same problem with 4.0.4RC2 and found a fix: | | Open the xml-file 'JBOSS_HOME/server/default/deploy/jboss-portal.sar/META-INF/jboss-service.xml' in an editor. | | Search for ... | name=portal:service=TreeCache,type=transient | | ... and add the line ... | dependsjboss:service=TransactionManager/depends | ... to the contents of the TreeCache mbean. I never could get it to work using jboss-portal-2.4 from CVS. Are the instructions in the readme.txt wrong, or am I just to green to read them correctly?

I believe they will work with #{member.age} and #{member.genderString}.
