EJB spec violation

petbos Jun 30, 2003 9:07 AM

I get always an EJB spec violation in the jboss log :
14:35:56,907 WARN [verifier] EJB spec violation:
Bean : Phone
Method : public abstract void remove() throws RemoveException, RemoteException
Section: 12.2.9
Warning: Each home method must match a method defined in the entity bean class.

My home interface looks likes this :

public interface PhoneNumberHome extends EJBHome {

public PhoneNumber create(Integer phoneId,
String firstName,
String lastName,
String phoneNumber)
throws RemoteException, CreateException;

public PhoneNumber findByPrimaryKey(Integer phoneId)
throws FinderException, RemoteException;

public void remove()
throws RemoveException, RemoteException;

}

The remove method in my entity bean look like this :

public void ejbRemove() throws RemoveException {

System.out.println("in ejbRemove");

try {
deleteRow(this.phoneId);
} catch (Exception ex) {
throw new EJBException("ejbRemove: " + ex.getMessage());
}
System.out.println("leaving ejbRemove");
}

What is wrong. Can anybody help or give me a hint.

Many thanks,

Peter

Hi I get this too, but I couldn't tell what is wrong with it, please shed some light? Thanks!

My LogMsgBean is like below:

public class LogMsgBean

public void ejbCreate () throws Exception
{
try {
Context ctx = new InitialContext ();
ds = (DataSource) ctx.lookup ("java:comp/env/jdbc/DSDefault");
}

ne.printStackTrace ();
}

CommFactoryParm cfp = CommFactoryParm.getInstance ();
cfp.addParm (CommFactoryParm.JMS_FACTORY, "SGConFactory");
cfp.addParm (CommFactoryParm.JMSMSGTYPE,
CommFactoryParm.JMSMSGTYPEOBJECT);

You probably need to throw a specific Exception implementation. The necessary declaration for ejbCreate is:
public void ejbCreate() throws javax.ejb.CreateException

Hi,

I've changed ejbCreate() to throw javax.ejb.CreateException it still gives this error

Here's my code, any clue??

public void ejbCreate () throws javax.ejb.CreateException
{
try {
Context ctx = new InitialContext ();
ds = (DataSource) ctx.lookup ("java:comp/env/jdbc/DSDefault");
}
catch (NamingException ne) {
ne.printStackTrace ();
}

CommFactoryParm cfp = CommFactoryParm.getInstance ();
cfp.addParm (CommFactoryParm.JMSFACTORY, "SGConactory");
cfp.addParm (CommFactoryParm.JMSMSGTYPE,
CommFactoryParm.JMSMSGTYPEOBJECT);

try
{
comm = CommFactory.getInstance (CommFactory.DYNAMICJMSQUEUE, cfp);
comm.connect ();
cHdr = new CommDataHdr ();
}
catch (CommFactoryException e)
{
throw new CreateException(e.getMessage());
}
catch (CommException ce)
{
throw new CreateException(ce.getMessage());
}

}

K.

I see.

You are not to throw any exceptions in the method. Since this method contract is between the container and the EJB during the creation phase of the EJB lifecycle it should not be interfered with by explicitly generating/throwing any exceptions.

why do u need a remove() on the ejbhome? There is a
remove(Object primarykey) defined in ejbhome interface.
