SAP and Java 2 Micro Edition

Hi Experts,
I am currently writing a series of blogs on Mobilizing SAP using J2ME mobile client.
Please have at my following blog and let me know your comments there about the same..

Any comments, suggestions and advice are most welcome..

Hello impseth,
It's really your call. J2ME is really a subset of J2SE. If you take the J2SE route, much of the APIs will not be applicable to J2ME. On the other hand, most of the literature deals with J2SE. Which makes learning "Java" much easier. My recommendation would be to learn both, because a some point you might want to write server side applications or at least understand how Java works on the server side. Start with J2SE.

  • Java Micro Edition and maps

    Hello all,
    I have recently mashed together a desktop application using swinglabs JxMapViewer. JxMapViewer basically does all the map downloading, rendering, etc for me and lets me concentrate on my application.
    Now I wish to port my application to Java Micro Edition, but JxMapViewer unfortunately doesn't work in Java ME. So I need a replacement.
    Does anyone know of a vendor independent (as in can load maps from many different servers, google, yahoo, nasa) mapping api that is designed to work under Java ME?

  • Question about Java Micro Edition

    Hello,
    I am interested about writing a program for PDAs. These seem to be running the Java Micro Edition, so I guess this is a good choice. But what about programming the GUI with the j2me? Afaik, it does not support swing, and the specifications are so full of abbreviations that I do not undertand that I really don't know other than to simply ask here about the possibilities of GUI programming with j2me, is there a "standard" gui library for j2me, or is it device-dependant, and is it possible to install the j2me under windows/linux for developing and testing purposes?
    Help please.. ;-)
    Thanks
    Jan

    thx :) J2ME seems to be very interesting. But zeb is right with the post in the discussion thread for this article, "where to start" is an important questions. So please, sun, make it easier for us to us (hobby-)programmers to adopt J2ME..
    I found this one alternatively:

    does anyone have experiences with it?

  • Help in Java Micro Edition SDK 3.0 EA...

    Hi, I am using the Java Micro Edition SDK 3.0 EA version. I have a problem that when i write code to access the RecordStore, it does not seem to work. Plus, for the FileConnection programs, where do i store the accessible file structure on the disk. In WTK, it was under the appdb of the specified emulator, but i dont know the path from where the filesystem is mounted.
    Another problem is that, I want to create a simple Java class in a separate file in the SDK. But, when i right click and select "New" on the project, it only shows options to create MIDlets or MIDlet Canvas files..
    Any help will be highly appreciated. Thanks..:-)

    About the file structure in FileConnection, in NetBeans it is in C:\Documents and Settings\[your user name]\j2mewtk\2.5.2\appdb\root
    You can change the root folder if you go to "manage emulators", then in "tools & extensions", click on "open preferences" and then select "storage". I don't know if SDK 3.0 has it too... sorry... I switched to NetBeans because it has more options...
    About creating a separate file, I always did it manually, adding a .java file to the src directory (with notepad, for example). Again with the full NetBeans, right-clicking in the project gives you an option to create a new Java class so you don't have to do it manually.
    About the record store, I don't know, sorry... But I answered 2 of 3! :)

  • Java Micro Edition and Smart Phone Programming

    I have successfully installed Java 2 Micro Edition 8.1 on my computer, and the Micro EditionNnetbeans plugin in.
    I am programming with netbeans.  In order to create a new project, I need to have the
    Java ME Embedded Emulator (Oracle) going on a near-enough virtual mobile phone. I can either
    virtualise my phone entirely, or used a real phone plugged in.
    -Is there a command line tool that comes with my version of micro edition java
    which can generate a JAD file from a completed, manifest-written executable
    .Jar file?
    -Can someone tell me what to do with the emulator to get it running in either mode,
    given that I know all the manufacturing details about my particular Smart Phone?

    It depends on how advanced the midlet will be. If standard components are used, the app should work everywhere, otherwise it need to be tested (it need to be tested always). If You need to write a midlet with Location API You first need to find a device that has this api implemented to test your application and the start writing. One importatnt thing, if a device in it's specification has written that it support Location API it doesn't have to mean that it's supported fully, some functions may not be implemented. As You can see here for instance. If You are not familiar with midlets start with a tutorial for beginners and after finishing try using more advanced APIs.

  • Flow of tables information between sap and java

    hi,Kondani
    as JCO offers both Client side and server Side programming.
    you can use JCO to connect SAP ABAP.outbound and inbound.
    1) JCO example 5 is about Server side programming java code. And you can see the data mapping is this example.And you must use sm59 to define the connections in SAP before you start.
    2) example 1 is about client side programming.
    try example 1 first. you can get a table from SAP using BAPI.
    Lots of JCO weblog you can see here

  • Sap and java

    I am currently working on a project and there are number of things that are involved such as SAP ( all transactions are stored in Sap). I developed an access database which is responsible in storing some data and then produces reports. I like to get some data from SAP system and then dump these data into my access database. Sap administrator are keep saying .. it is impossible to get data from SAp and then put inot access. I suggested that l can develop a java application to interect SAP (to get the data ) and then put into access.
    Is this possible.... if my question is not clear ... l will rephrase later.

    It would (in theory) be possible if you had the necessary maintenance contract (and then the JDBC driver) But even so you will likely need some significant support from the SAP admins since the data model is not always intuitive (read: horrendous). This is all just my opinion of course, maybe your experience will be different.
    Good Luck

  • I there any dependcy between Java Enterprise Edition and Java standard Edit

    Hi Friends,
    Is J2EE 1.4 uses Java SDK 1.4 or 1.5.Please reply as earlier as possible.It is urgent
    Thanks
    Bye

    Each version of the Java EE platform must be able to run on the associated version of the Java SE platform. So, J2EE 1.4 must be able to run on J2SE 1.4 , Java EE 5 must be able to run on Java SE 5, etc. Note that this doesn't mean a particular implementation of Java EE can't be run with a more recent version of the JDK. For example, the J2EE 1.4 SDK can be run with J2SE 1.4 or Java SE 5. The key is that both the implementation of the Java EE platform and the applications written to that particular release of the platform must write to the corresponding Java SE version API. In other words, neither a J2EE 1.4 implementation nor a J2EE 1.4 application should make use of an API that was added in Java SE 5.

  • Data transfer b/w SAP to Java using IDOC and Interface SAP Jco

    Dear Experts,
    The challenging requirement we are having is, we need to create the interface for data transfer between SAP system and the Java system. The data will be transferred from SAP to java and similarly once some processing done in Java again the details needs to be transferred from Java to SAP.
    For this data transferred we are planning to use IDOC process and for interface "SAP Java connector (Version 3.0.5)" we are planning to use. As per our understanding, from Java side one program needs to be written to connect with SAP as "Registered program". This registered program will appear in SAP GATEWAY automatically and using tRFC, TCP/IP connection both SAP and Java system will be connected.
    In this case we are having some doubts.
    1. The data from SAP is going to be transfered from one Custom transaction (Z tcode). Once "Outbound IDOC" will get triggered and will carry the details. Now the doubt is, whether the data / details will get transfered to JAVA system automatically or we need to perform any other steps from SAP ABAP coding...(like converting in to flat file, XML file and etc) ??
    2. We are planning to install "SAP Jco" in Java server. Is this correct...??
    3. Other than SAP Jco any other softwares needs to be installed or not..??
    4. Since we are going to trigger the "outbound IDOC" from custom transaction, we are planning to develope one program in SE37. Other than this any other program we need to develop or not..??
    5. Any sample Java program for the SAP Jco version 3.0.5 to create the "Registered program" with SAP..? (e.g. SAP Listener program).?
    If anybody has detailed steps or explanation please share it with us.
    Thanks in advance
    Warm Regards,
    VEL

    Hi All,
      For the above mentioned issue, we implemented JCo software in JAVA system and created the JAVA program including SAP logon credential details like Client, User name, password and Language details.
    When this JAVA program was compiled successfully then, that non SAP system will appear in SAP gateway Tcode.
    Once non SAP system started appearing in SAP gateway that means, both SAP & Non SAP are connected automatically.

It is necessary for write a serious, large programs and for compatibility android java apps with symbian

    This is more of a developer question than a consumer question.  You may try the Java discussion boards on Forum Nokia.  If you do post there, you may want to include the specific functionality of J2SE that you are missing in J2ME so that more experienced developers can suggest alternatives.
