Hello,
I read again the EJB specification about this but I
do not find any precision.
We have considered that the ejbFind<method> must return
an empty Enumeration instead of a null enumeration.
The ejbFind<method> code may be:
public Enumeration ejbFindNothing() {
java.util.Vector v = new java.util.Vector();
return(v.elements());
}
Any reference to a part of the EJB specification about this
will be welcome.
Best regards.
H�l�ne.
