Hello Alex,
if you say 'only for local interfaces' you mean that the Home interface is
Local (LocalHomeEmployee) ?!
*
* @ejb:bean name="masterdata/Position"
* display-name="Masterdata Position Entity Bean"
* type="CMP"
* cmp-version="2.x"
* jndi-name="ejb/masterdata/Position"
* view-type="local" <------- ????
Is this correct ?
Thanx
Bjorn
