My code:

[code]

private StatusLocalHome statusHome = null;

...

public void setSessionContext(SessionContext context)

{

...

Status obj = jndiContext.lookup("java:comp/env/ejb/EEIMStatus");

statusHome =

(StatusLocalHome) PortableRemoteObject.narrow(

obj,

StatusLocalHome.class);

...

}

...

public int removeStatus(long id)

{

try

{

StatusLocal statusLocal =

statusHome.findByPrimaryKey(new Long(id));

statusHome.remove(statusLocal);

return 1;

}

catch (EJBException ex)

{

throw new EJBException(ex.getMessage(), ex);

}

catch (FinderException ex)

{

throw new EJBException(ex.getMessage(), ex);

}

catch (RemoveException ex)

{

throw new EJBException(ex.getMessage(), ex);

}

}[/code]

Hello Daniel,

The first problem that I see is the usage of PortableRemoteObject.narrow method - it must be used only in the case when remote EJB reference is obtained. I assume in your case the EJB reference is local.

The real problem, however, is the wrong parameter in the remove() method. I suppose it causes the ClassCastException. The parameter must be the primary key, not the EJBObject reference. The code should be:

statusHome.remove(new Long(id));

instead of

StatusLocal statusLocal =

statusHome.findByPrimaryKey(new Long(id));

statusHome.remove(statusLocal);

I hope this helps.

Regards,

Svetoslav
