<html><div style='background-color:'>Right strategy for using local
interface over remote:
Unless your application is inherently distributed, I recommend against
using EJBs with remote interfaces.
Use the local interfaces as a default choice for EJBs, and remote
interfaces a special case. 
 <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
:office:office" /><o:p></o:p>
There are some consideration you have to follow when you choice to
implement both local and remote interfaces such as: they cannot extend a common
superclass, as every method on the remote interface must be declared to throw
RemoteExcetion while methods on the local interface must not be declared to
throw this exception. 
 <o:p></o:p>
Secondly:
<H1 style="MARGIN: 0in 0in 0pt">
You have to be sure that the deployment descriptor
has the entries for local interfaces not remote interface, I don�t think that
you can have both entries in the same enterprise beans entry in the ejb-jar-xml
. I do think that you put the remote interface entry then, the local one in the
ejb-jar-xml. So you can lookup the remote interface through the JNDI not the
local.</H1>
<H1 style="MARGIN: 0in 0in 0pt">
try to keep only the local interface entry, take
out the remote one and i think it will work.</H1>
