Web Applications for mobile devices

Posted on Sep 07, 2005 at 02:47 PM 22 Views

Hello experts,

I try to write some SAP Web Applications for Mobile Devices and they should be device-indepent if possible.

I'm thinking about the following ways(We have Web AS 6.30):

BSP: Develop my own BSP-Extensions which render different Layout by unsing client_info.

Use HTMLB for JAVA. How can I get the package com.sap.mobile.htmlb? (Excuse my beginner question 😉) Is there more information about how to use it?

Any comment, suggestion and information will be very appreciated

Regards

Vivian

    Hello Vivian,

    I am not an expert but you can also make use of mobile Web Dynpros if it is an online transaction! I did make one application, it runs well on the PDA. The layout changes from what you would see in normal PDA to Black berry though.

    http://help.sap.com/saphelp_nw04/helpdata/en/7d/28fa3e7cb1d861e10000000a114084/frameset.htm

    Hope the above links help.

    When a mobile application is running offline and exchanges data with an application backend system (like any application within mySAP Business Suite or any other legacy application), use MI which can also be developed from SAP NetWeaver Developer Studio.

    Cheers,

      Hi Frank,

      you are right. I seem to make the things more complicated with extensions, maybe it's not necessary.

      I think I should explain my problem again.

      My work is not to develop some online-Applications for mobile devices, not exactly. I need to develop a 'converter' to transform the applications so that I don't have to rewrite every applications which already exist, for mobile devices. So I got the idea of extensions. I was thinking of developping a set of extensions which handels the rendering for different devices(just like the object tags in BW-Web-reporting). And my converter program just replaces the elements of the Sourceprogram with the Tags of my extensions. I thought it might look better. 😉

      I hope my own extensions work on mobile devices (that's what I'm worried about. )and it is not much more work to go this way instead of just with html/css for the layout. I'll make some attempts.

      Greeting from Augsburg 😊

      Vivian

    Hello Vivian,

    for the online mode the best way seems to be Mobile WebDynpro.You can perhaps install a 6.40 WAS for the mobile WebDynpro User Interfaces and then connect to your lower WAS systems in the WD-Model via RFC/WebService.

    For your java-htmlb question i found an answer at help.sap.com: "To run Mobile HTMLBusiness for Java, you must install the two packages com.sap.mobile.clientinfo and com.sapportals.htmlb in the Java Servlet Engine environment".

    For BSP you are right,there you get some problems with the extensions. I developed a online BSP solution without using the extensions(only html-Layout).

    This works fine at devices like WLAN PocketPC and PDA.

    Greetings

      hello ravi,

      mobile infrastructure only supports disconnected i.e.

      offline solutions at the moment. online applications

      for mobiles is currently supported only thru WD mobile

      UI framework; and doesn't require the MI server components

      to work.

      regards

      jo
