In my opinion, WS would be a better =
choice
because it reduces the coupling between the modules and provides higher
extensibility. AFAIK, SOAP does not have any scalability issues. I have =
used WS
to pass large amount of data (not more than 100K), but did not observe =
any big
issues. Moreover since it uses HTTP, you do not have to setup an =
additional
tunnel. Therefore from a security point of view also you might not end =
up with
any concerns if you use WS. But here, if the server needs to push some =
data without
the client requesting for it, WS cannot work for =
you.<o:p></o:p>

Hi Folks,<o:p></o:p>

<o:p> </o:p>

         =
  
I have a design question where I would like some feedback. I want an =
applet to
communicate an J2EE server behind a firewall. The scheme of =
communication
between these two entities will be push and pull (where applet can push =
and
pull data from the J2EE server).<o:p></o:p>

<o:p> </o:p>

At one time I had implemented RMI mechanism but it =
was a
situation without firewalls. I know that through RMI you can tunnel =
across
firewall.<o:p></o:p>

<o:p> </o:p>

Which of these two schemes is the =
best?<o:p></o:p>

<ul style=3D'margin-top:0in' type=3Ddisc>
<li class=3DMsoNormal style=3D'mso-list:l1 level1 lfo3'>.Use RMI to have =
applets call
EJBs ?<o:p></o:p></li>
<li class=3DMsoNormal style=3D'mso-list:l1 level1 lfo3'>Use Webservices to =
implement
SOAP between applet and EJB?<o:p></o:p></li>
</ul>

<o:p> </o:p>

Another requirement is that the data passed between =
the
applet and J2EE server is considerably high. I have heard arguments that =
using
SOAP will not scale well.<o:p></o:p>

<o:p> </o:p>

Is there any alternate option than the =
above?<o:p></o:p>

<o:p> </o:p>

Thanks<o:p></o:p>
