Hi,
I´m just getting started and this is my problem trying to map a single
class. Find below the table structure, the BusinessObject java class, the
repository.xml, the class I´m using to run the test and the exception I´m
getting.
I hope somebody can help my to spot what is wrong...
Thanks...
The table structure is ...
CREATE TABLE `user` (
`id` int(11) NOT NULL default '0',
`firstName` varchar(50) default NULL,
`lastName` varchar(50) default NULL,
`email` varchar(50) default NULL,
`password` varchar(50) default NULL,
`status` char(1) default NULL,
PRIMARY KEY (`id`)
) TYPE=InnoDB ROW_FORMAT=DYNAMIC;
The BO is...
package com.jose.forum.businessobjects;
public class UserBO implements java.io.Serializable {
private int id;
private String firstName;
private String lastName;
private String email;
private String password;
private String accountStatus;
//public UserBO(){
// super();
//}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAccountStatus() {
return accountStatus;
}
public void setAccountStatus(String accountStaturs) {
this.accountStatus = accountStatus;
}
}
The repository-user.xml is...
<class-descriptor
class="com.jose.forum.businessobjects.UserBO"
table="user"
<field-descriptor
name="id"
column="id"
jdbc_type="INTEGER"
primaryKey="true"
autoincrement="true"
/>
<field-descriptor
name="firstName"
column="firstName"
jdbc-type="VARCHAR"
/>
<field-descriptor
name="lastName"
column="lastName"
jdbc-type="VARCHAR"
/>
<field-descriptor
name="email"
column="email"
jdbc-type="VARCHAR"
/>
<field-descriptor
name="password"
column="password"
jdbc-type="VARCHAR"
/>
<field-descriptor
name="accountStatus"
column="status"
jdbc-type="CHAR"
/>
</class-descriptor>
The class I´m using to test is...
public class Test {
static Implementation odmg = null;
static Database db = null;
public static void main(String args[]) throws ODMGException{
UserBO user = new UserBO();
user.setId(0);
user.setFirstName("Jose");
user.setLastName("Hernandez");
user.setEmail("[EMAIL PROTECTED]");
user.setPassword("jose");
user.setAccountStatus("A");
init();
Transaction tx = odmg.newTransaction();
tx.begin();
db.makePersistent(user);
tx.commit();
destroy();
}
private static void destroy() throws ODMGException{
db.close();
}
private static void init() throws ODMGException{
ConnectionRepository cr =
MetadataManager.getInstance().connectionRepository();
JdbcConnectionDescriptor jcd = new JdbcConnectionDescriptor();
jcd.setJcdAlias("jfhForum");
jcd.setUserName("web");
jcd.setPassWord("web");
jcd.setDbAlias("jfhForum");
jcd.setDbms("MySQL");
cr.addDescriptor(jcd);
PBKey key = new PBKey("jfhForum", "web", "web");
PersistenceBroker broker = PersistenceBrokerFactory.
createPersistenceBroker(key);
odmg = OJB.getInstance();
db = odmg.newDatabase();
db.open("jfhForum", Database.OPEN_READ_WRITE);
}
}
I get the below exception...
