Problem by accessing Entity Bean
I created a table as follow:
create table Book(
ID VARCHAR2(10 BYTE) NOT NULL,
Name VARCHAR2(40 BYTE),
Author VARCHAR2(10 BYTE),
Public_Date DATE,
Description VARCHAR2(15 BYTE),
primary key (id)
)
insert into book values('01', 'My Book', 'Wei Chen', to_date('19960725','YYYYMMDD'), 'No Comment');
Then I created an Entity Bean "BookBean" with XDoclet based on this table. The XDoclet generated several java files such as BookBean.java, BookCMP.java etc.
I deployed the EAR to the JBoss 4.2.2. GA.
Then I try to access the Entity Bean from a Standalone Client. The code looks as follow:
...
Book book = null;
try {
BookHome bookHome = BookUtil.getHome();
book = bookHome.create();
} catch (Exception exception) {
exception.printStackTrace();
}
...
But I get Exception as follow:
javax.ejb.CreateException: Error checking if entity exists:java.sql.SQLException: invalid schema name: TEST in statement [SELECT COUNT(*) FROM TEST.BOOK WHERE ID=?] at

In the class "BookBean.java" there is a function as follow which is automatically created by XDoclet:
public java.lang.String ejbCreate() throws javax.ejb.CreateException {
// EJB 2.0 spec says return null for CMP ejbCreate methods.
// TODO: YOU MUST INITIALIZE THE FIELDS FOR THE BEAN HERE.
// setMyField("Something");
// begin-user-code
this.setId("01");
return null;
// end-user-code
}
...
The code "this.setId("01");" was added by me.
Any tips?
