Hi Matt,
presently i'm working with appfuse 2.0 (struts2) application. i have one
problem how to use composite primary key using hibernate in this application
My model class code like this
@IdClass (value=MenuPk.class)
@Entity
@Table (name="App_Menu")
public class Menu extends BaseObject implements java.io.Serializable {
@Id
@Column (name="MenuID",nullable=false)
private Long id;
@Id
@ManyToOne (targetEntity=Product.class)
@JoinColumn (name="Product_ID")
private Product product;
.............
}
public class MenuPk extends BaseObject implements Serializable {
private Long id;
private Product product;
...........
}
the IdClass changes are done after run the mvn appfuse:gen -Dentity=Menu
it compiles and runs perfectly, but when i need to access the list in web
page it throws an exception(Data Failure Exception page )
in the server console it shows
sql column error "id" column not existed
sql column error "product" column not existed
My database data is like this
MenuID Product_ID .....
1 1 .......
2 1 .......
3 1 .......
1 2 .......
2 2 .......
3 2 .......
please suggest me how to solve this problem ( it is an urgent requirement to
me)
