Hey,
I have created a J2ME mobile client so that even a low end mobile device can support it. It makes an HTTP connection to SAP Web AS which in turn makes a connection to the R/3.
I am able to retrieve and update data successfuly.
Has anyone worked on similar technology.
Any suggestion or comments about the same will be appreciated. Is this solution feasible?
What could be the bottleneck in this scenario?
Please let me know.

Tanveer.
hello tanveer,
if your application is just small enough, a customize
application would suffice. but later if you will be implementing
more and more features to support concurrent updates from
multiple clients, it will become a difficulty. SAP MI is
an offline mobile solution framework which offers several
features like delta handling and so on... it also uses
HTTP to exchange data with the MI server.
if your are designing an online application however, SAP
also has a WebDynpro framework which is also supports mobile
clients.
if you can give us more details on what you actually have
in mind, perhaps we can suggest/share some more ideas...
regards
jo

Hey Jo,
Thanks for your comments. I agree we have web dynpro solutions for mobiles. But does the lower end mobile capable of handling this?
Lower end mobiles these days support java development and thus shall be able to interact with the server.
.Net mobile solutions i guess requires higher end mobiles and PDA's.
So I thought of building mobile application using J2ME.
How does MI handle support concurrent updates. Also, how is the landscape using MI.
Will I be making HTTP calls to MI which in turn connects to SAP or how is it like?
Please let me know...
Thanks.

Tanveer.
hello tanveer,
>But does the lower end mobile capable of handling this?
well, your client only needs a browser. but if you have to
code your own client and process raw http data, it would
only complicate things up if you'll be using web dynpro
since it also make of javascripts.
btw, are you creating an application for http data exchange
with your server? and is this in online or offline manners?

SAP MI is an offline solution. so you have check first if
this caters to your requirements. MI architecture involves
3 components - MI client, MI server and backend.
MI client serves as a platform and exposes APIs for developing
an application on top of it. APIs for data persistence,
synchronization with the server, delta handling and so on.
from MI client, HTTP/s is used in posting data to the MI
server which processes your posted and convert them to
objects for further processing... it will be too long to
discuss the whole architecture here; so i would rather
suggest you to have a look at the <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/21eba3a7-0601-0010-b982-92f1fca3258a">Mobile Development Kit</a>.
it explains the MI archiecture and have some samples as well.

please guide us........
i will mail you regarding the same with breif project structure.
Thanks and Regards

hello tanveer,
i missed this post... and sorry for the late reply.
i now avoid disclosing any contact info (email, phone #
and the like) to the public. i had received emails (from
someone i don't know) saying that my blogs are worthless
and calling me stupid... could be somebody who is also an
SDN member and has read my blogs.
i can send you my email address to which you can contact
me. please post an email address where i can send it.
