I have simple EJB with CMP fields
it does not have ejbCreate() & ejbPostCreate() functions, but has
ejbCreate(long pk) ejbPostCreate(long pk) functions. Primary key class
in
deployment descriptor is java.lang.Long
Here is extract from class definition:
public class RoleBean implements EntityBean {
public long roleID; //this is primary key
public String roleName;
public void ejbPostCreate(long roleID) throws CreateException {
}
public java.lang.Long ejbCreate(long roleID) throws CreateException,
DuplicateKeyException {
this.roleID = roleID;
roleName = "";
// In CMP, should return null.
return null;
}
//.....
}
public interface RoleHome extends EJBHome {
public Role create(long roleID) throws CreateException,
RemoteException;
public Role findByPrimaryKey(java.lang.Long pk) throws
FinderException, RemoteException;
public Enumeration findByName(String roleName) throws
FinderException, RemoteException;
public Enumeration findAll() throws FinderException,
RemoteException;
}
all bean classes compile successfully & are deployed in EJB container.
My client application can successfully retreieve & update bean
information, but as soon as i try to write code to create new bean using
create(long pk) it does not compile, giving following compilation error.
RoleClient.java:57: create() in bmall.ejbs.RoleHome cannot be applied to
(long)
Role role = home.create(1L);
and here is my client code
public class RoleClient {
public static void main(String[] arg) {
try {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.rmi.registry.RegistryContextFactory");
p.put(Context.PROVIDER_URL, "rmi://localhost:1099");
Context initialContext = new InitialContext(p);
RoleHome home = (RoleHome) initialContext.lookup("Role");
//following lines compile and executes with no problem updating
database record
Role role = home.findByPrimaryKey(new Long(0L));
role.setName("updating role name");
//this line fails to compile with above error message
Role role = home.create(1L);
} catch (Exception e) {
e.printStackTrace();
}
}
these do not really make sence to me, but most likely i am missing
something
very important.
Thank you very much for your help
