For J2ME Wireless Toolkit Beta 2

I wrote a project with this toolkit, I test it and it works fine with the
Run MIDP Application. I tried to install it in the Nokia 72XX (Handphone of my
fried, sorry forget the model). It reported "Invalid Jad file"
Any suggestions?
Thanks a lot in advance!

I tried with the 7210 again, but it still insists that it is an invalid .jad file
I put mine .jad file below. I am not sure which line makes the difference.
MIDlet-1: atest, atest.png, SpaceGame
MIDlet-Jar-Size: 100
MIDlet-Jar-URL: atest.jar
MIDlet-Name: atest
MIDlet-Vendor: Sun Microsystems
MIDlet-Version: 1.0
in the atest.jar file, there is
App.png
SpaceGame$SpaceCanvas.class
SpaceGame.class
Sprite.class
MANIFEST.MF (this file is in path meta-inf\)
My friend download the valid .jad file, its .jad file is some different from the one I post above. Since yours works fine, can you tell where the error comes from?
Thanks a lot for your help!

  • J2ME Wireless Toolkit 2.5

    Hi all,
    I would like to ask if this new veresion (J2ME Wireless toolkit 2.5) supports ArrayList.
    I have developed a program with ArrayList , is it possible to run it in this new version without problems.
    Thanks

    New version of WTK 2.5 supports CLDC stack. Unfortunately the ArrayList class is not present in the spec for this stack, so WTK 2.5 will not be able to run your application. (Like all other CLDC implementations) But you can try the CDC emulator "Sun Java Toolkit 1.0 for CDC" at http://java.sun.com/javame/downloads/index.jsp
    (CDC stack has the class ArrayList)

  • Image problem with my palm (J2ME Wireless Toolkit)

    Hi,
    I did a basic application. I just show an image and it works perfectly with the J2ME Wireless ToolKit.
    However, when I create the package, convert it and send it on my palm, everything is ok, except the image. It won't appair.
    I get an exception that the image couldn't be found, but when I use the emulator, everything is ok !!!
    The image is in the "res" directory, like it was asked in the manual.
    I tought that everything is encoded (text file or image file) when you create the package. If it's working with the emulator, why is it not working on my palm?

    I had a same problem with my nokia 3650 in J2me the image appears but not on the phone, I think that that is a bug and fixed it this way:
    when you make a jar package, unpack package with winRAR or some archive program in some temp directory and in that directory make a res directory an put the image in it, then repack theese files again including the res directory in a new jar file. It works for me. It looks that J2ME in compiling doesn't change the path, to root but leaves the res directory.

  • Does J2ME Wireless Toolkit Check Memory Usage?

    I just want to confirm that does the J2ME wireless Toolkit check the memory usage by a MIDlet and only allow it 128KB of memory usage as specified by the MIDP 2.0 specification???
    Or do we have to calculate and check manually about the memory usage of a MIDlet???

    Hi,
    The WTK doesnt set heap memory unless u specify in the preferences. Most of the devices allow upto 200 KB heap size or more. The least being Nokia 7250 which allows only upto 200 KB heap size. SO if u are developing for a particular device in mind specify the heap size in the preferences. You will also get the memory utilized at runtime thru.
    Runtime.getRuntime().* functions. eg.
    Runtime.getRuntime().freeMemory();
    wil give u free memory.
    in new emulators such as Nokia 7210 emulator , u can see the memory real time , on the details secction.
    Hope this helps.

    Dear Everyone,
    I had just installed J2ME Wireless Toolkit 1.0.4 but when I click on the shortcut to launch the software, nothing happen..Please advice...
    Thank you..

    Hi dumb00,
    I had reinstall my JDK and J2ME for around 5 times since yesterday.
    Later, I found out that is the corrupted fonts in my computer that cause this problem.

    Thanks you for responding, dumb00.

  • A problem of https in Wireless Toolkit  beta

    Hi,
    I am using J2ME Wireless Toolkit 2.0 to get a https connection. When I tried to use statement "hs_conn = (HttpsConnection)Connector.open(url);"
    to get a connection to my server. url is varible here and has something like "https:\\129.173....". I got a meessage in the default color phone say "Client wants to send information. Here no problem. This will require the use of airtime which may cost you money. is it ok" then four items follows the message, then an "ok" at the right bottom of screen. I pressed the ok button(it is exactly below the ok). The default color phone is frozen. No any connection gets and No any work can be done after then. I have to destroy the color phone and rebuilt my code but still get same result.
    Does somebody have experience on it and give me a hand
    thanks a lot
    Eric

    Eric,
    I've seen the same problem with a non-secure connection. That is, the problem is not related to https. Unfortunately, I do not have a solution. I did find that you can work-around the problem depending on where you locate your logic to make the connection (example, startApp). It's not much of a work-around unless you want to make a connection and leave it open for your entire session and you have a simple app.
    When using WTK 1.0.4_01, I did not experience this problem when I ran the exact same code.

  • Java Forte CE and J2ME Wireless Toolkit configuration

    I installed Sun Java Forte V3.0 Community Edition and the J2ME Wireless Toolkit 1.0.3.
    I not able to run a MIDlet for the PALM OS Emulator. Wen I execute the MIDLet suite, the output windows returns: "Error could not find a JVM"
    - Does any body knows how to properly configure Java Forte to run application on the Palm OS Emulator (POSE).
    - Does any body knows how to attach Sun Forte debugger for MIDLet applications ?
    Thanks

    hi,
    First Install the forte and then install the j2mewtk.While installating j2mewtk chose integrated option.
    For Palm OS emulator you have to set the POSE location.
    Try out this.
    Open ktolbar.
    OpenProject.
    select an application.(examples)
    set device PalmOS_device.
    Now run the application.
    A window pop for u.
    This may help you
    good luck.

    HI Phoenix_Mj
    I'm a beginner in J2ME world and it might happen that I'm be missing some impt step from coding to transferring.
    Do I have to configure anything?
    Im I right by saying, only the .jar file is then transmitted to the device?
    Lastly, where should I put my images? what folder to be specific?
    I can't run the application correctly even trying to run it over the OTA....
    No images is being displayed...
    Please help guys.
    By the way thanks, Phoenix_Mj

  • J2me wireless toolkit and MIDP,CLDC

    Hi,
    does the j2me wireless toolkit ship the cldc and midp with it ?

    why email, thats a forum because there are more people interested in problems and their solution than you.
    The 2.2beta also ships with the CLDC 1.1 and MIDP 2.0. Its a must because without it, you wouldnt be able to execute anything. And you cant put the JVM, MIDP and CLDC on your phone. The only thing you need is your application. The rest is implemented in hardware (or firmware of the phone). If not, theres no way to ''manually'' put in there (this includes upgrading).

  • Question about java 5.0 & j2me & wireless toolkit

    Hi,
    I maybe have a dumb question, but to me it's not totally clear. I am currently developing an application (for J2ME and J2SE) which uses RSA encryption. So I found out that before Java 5.0 RSA encryption wasn't supported, but starting from Java 5.0 it is. So my question now is. If I use the RSA encryption from Java 5.0, can I still use it in my cell phone? And which Java version runs in my cell phone?
    It not clear to me, but maybe someone will be so nice to respond...
    Can my/any cellphone run Java 5.0 code? So what if I use the mentioned RSA-cipher... or generics...enumerations... On what does it depend whether I can use it for my cell phone or not?
    Does it just depend on the compiler? the JVM on my phone? or even the wireless toolkit?
    Thank you very much in advance.
    Sincerely.

    bump...
    anyone?

  • J2ME Wireless Toolkit 1.0.3 Beta

    I'm now using J2MEWTK 1.0.3 Beta to test my J2ME applications and it runs smooth, however I faced a problem when trying the OTA download.
    After I ran the OTA (emulator -Xjam) and typed the correct location of my JAD files, it showed a list of applications I have on server, but when I've choosed one of the application and clicked "install", it asked me to check the JAD file. Can anyone help, thanks a lot.
    Moreover, if I just click the JAD file on my PC, it can download the JAR file from server and run it.

    I stand corrected in my previous reply.
    You must check the .jad file that resides ON THE WEB SERVER with the correct URL pointer attribute and also make sure the .jar file exists in the correct location.
    Also you need to ensure that the MIME type on the webserver for .jad files is set and looks like this:
    MIME=text/vnd.sun.j2me.app-descriptor
    , so that the webserver returns the correct MIME type to the Java Application Manager on your emulator or J2ME device.
    All you need to have in your MIDlet are lines of code that will open a HTTP connection to the HTML page on the webserver that contains a HREF tag pointing to .jad file that has the URL pointer attribute that points to the .jar MIDlet app file.
