[EJB 3.0] - Mapping-Problem with Primary-Key containing three Foreign-Ke
by ttrepper
Hi all,
I am sorry, but i cannot get it working. I have three tables with a PK beeing a single attribute. And then I have another table, with three attributes each referencing the PK of one table. And these three attributes are at the same time the PrimaryKey (PK)
SQL looks like this:
| CREATE TABLE ListedSections (
| SectionID SMALLINT NOT NULL,
| SectionName CHARACTER VARYING(50) NOT NULL,
| SectionDescription CHARACTER VARYING(150),
| DateAdded TIMESTAMP DEFAULT current_timestamp,
| ActiveUntil TIMESTAMP,
| CONSTRAINT PK_ListedSections PRIMARY KEY (SectionID)
| );
|
| CREATE TABLE ListedRights (
| RightID SMALLINT NOT NULL,
| RightName CHARACTER VARYING(50) NOT NULL,
| RightDescription CHARACTER VARYING(150),
| DateAdded TIMESTAMP DEFAULT current_timestamp,
| ActiveUntil TIMESTAMP,
| CONSTRAINT PK_ListedRights PRIMARY KEY (RightID)
| );
|
| CREATE TABLE ListedRoles (
| RoleID SMALLINT NOT NULL,
| RoleName CHARACTER VARYING(40) NOT NULL,
| RoleDescription CHARACTER VARYING(150),
| DateAdded TIMESTAMP DEFAULT current_timestamp,
| ActiveUntil TIMESTAMP,
| CONSTRAINT PK_ListedRoles PRIMARY KEY (RoleID)
| );
|
| CREATE TABLE RoleHasRights (
| RightID SMALLINT NOT NULL,
| RoleID SMALLINT NOT NULL,
| SectionID SMALLINT NOT NULL,
| CONSTRAINT PK_RoleHasRights PRIMARY KEY (RightID, RoleID, SectionID)
| );
|
| ALTER TABLE RoleHasRights ADD CONSTRAINT ListedRights_RoleHasRights
| FOREIGN KEY (RightID) REFERENCES ListedRights (RightID);
|
| ALTER TABLE RoleHasRights ADD CONSTRAINT ListedRoles_RoleHasRights
| FOREIGN KEY (RoleID) REFERENCES ListedRoles (RoleID);
|
| ALTER TABLE RoleHasRights ADD CONSTRAINT ListedSections_RoleHasRights
| FOREIGN KEY (SectionID) REFERENCES ListedSections (SectionID);
|
My Entities are looking like this:
| package myPackage;
|
| import java.io.Serializable;
| import java.sql.Timestamp;
| import java.util.Collection;
| import java.util.ArrayList;
|
| import javax.persistence.Entity;

| import javax.persistence.Table;
|
| @Entity
| @Table(name="listedroles", schema="public", catalog="postgres")
| public class Role implements Serializable {
| private static final long serialVersionUID = 1L;
| private int roleid;
| private String roleName;
| private String roleDescription;
| private Timestamp dateadded;
| private Timestamp activeuntil;
| private Collection<RoleHasRights> roleHasRights = new ArrayList<RoleHasRights>();
|

Can anybody help my getting this working? Thank you very much and kind regards,

This looks like regression to me. What libraries are you using with your project? RichfFaces?

You mean a logical outcome right?

[EJB 3.0] - is this a bug in EJB?
by mnrz
hello
I have some entity in my application, when I declare a method starting with term "is" the database will be updated with a new field whereas I didn't declare that field as a database field
here is an example:
| import static org.jboss.seam.ScopeType.SESSION;
|
| import java.io.Serializable;
| import java.util.HashSet;
| import java.util.Set;
|
| import javax.persistence.CascadeType;
| import javax.persistence.Column;
| import javax.persistence.Entity;
| import javax.persistence.FetchType;
| import javax.persistence.GeneratedValue;
| import javax.persistence.Id;
| import javax.persistence.OneToMany;
| import javax.persistence.Table;
|
| import org.hibernate.validator.NotNull;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Scope;
|
| @Entity
| @Table(name ="group_permission")
| @Name("group")
| @Scope(SESSION)
| public class Group implements Serializable{
|
| private String name;
| private Long id;
| private Integer permissionGroup = new Integer(0);
| private Set<Permission> permissions =new HashSet<Permission>();
| private static final int Export_Permission = 8;
| private static final String All_Permission = "*";
|
| @OneToMany(mappedBy="group", fetch = FetchType.EAGER ,cascade=CascadeType.ALL )
| public Set<Permission> getPermissions() {
| return permissions;
| }
|
| public void setPermissions(Set<Permission> permissions) {
| this.permissions = permissions;
| }
| @Id @GeneratedValue
| @Column(name = "id")
| public Long getId() {
| return id;
| }
| public void setId(Long id) {
| this.id = id;
| }
|
| @NotNull
| @Column(name="name")
| public String getName() {
| return name;
| }
| public void setName(String name) {
| this.name = name;
| }
| public boolean equals(Object o) {
| if (o == null)
| return false;
|
| if (!(o instanceof Group))
| return false;
|
| Group that = (Group) o;
|
| return this.getName().equals(that.getName());
| }
|
| public int hashCode() {
|
| return this.getName().hashCode()+720;
|
| }
|
| @Column(name="permissionGroup")
| public Integer getPermissionGroup() {
| return permissionGroup;
| }
|
| public void setPermissionGroup(Integer permissionGroup) {
| this.permissionGroup = permissionGroup;
| }
| public void setPermission(boolean permission){
| permissionGroup=0;
| if(permission){
| permissionGroup=permissionGroup | Export_Permission;
| }
|
| }
| public void addPermission(ColumnHeader ch ,String categoryName){
|
| if(permissions==null){
| permissions=new HashSet<Permission>();
| }
| if(ch.isDisplayable() ||ch.isSearchable()){
| Permission permission=new Permission();
| permission.setGroup(this);
| permission.setCategory(categoryName);
| permission.displayablePermission(ch.isDisplayable());
| permission.searchablePermission(ch.isSearchable());
| permission.setFieldName(ch.getName());
| permissions.add(permission);
| }
| }
|
| public boolean hasExportPermission(){
| if((Export_Permission & Export_Permission) == Export_Permission)
| return true;
| else
| return false;
| }
|
| public void setExportPermission(boolean export){
| if(export) {
| permissionGroup = permissionGroup | Export_Permission;
| }else {
| permissionGroup = permissionGroup & ~Export_Permission;
| }
| }
|
| public boolean hasDisplayPermission(String categoryName, String fieldName) {
| for(Permission p: permissions) {
| if(p.getCategory().trim().equals(All_Permission)){
| return true;
| }
| if(p.getCategory().equals(categoryName) && p.getFieldName().equals(fieldName)) {
| return p.hasDisplayablePermission();
| }
| }
| return false;
| }
|
| public boolean hasSearchPermission(String categoryName, String fieldName) {
| for(Permission p: permissions) {
| if(p.getCategory().equals(All_Permission)){
| return true;
| }
| if(p.getCategory().equals(categoryName) && p.getFieldName().equals(fieldName)) {
| return p.hasSearchablePermission();
| }
| }
| return false;
| }
|
| }
|
|
as you can see in above code represented in blue color, I have some utility method in my entity, if I rename the method hasExportPermission() to isExportPermission() the EJB will create a field in corresponding table with name exportPermission and because it returns boolean the type of the field will be tinyint(1) (using mySql)
I expect since I didn't declare it by annotations it shouldn't consider it as a table field, but it does!!!!
I want to know whether this is a bug or I made a mistake somewhere
it is remarkable to say that I am using JBoss Seam framework, but I don't think this is its fault.
thank you very much
