J2ME mobile client

[Former Member]

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.

Regards,

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...

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.

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.

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.
