    Hi Bartek,

    I come upon micro emulator while doing some research on running our j2me applet in a browser.

    I have a question on creating http connection.
    It was mentioned in microemu.org
    that "By default the applet will only communicate with the host the applet came from (your website)"

    Do you mean that if the midlet will communicate with the "host", then i dont need my midlet to be sign?

    Declaring something like:

    Please shed me my some light.

    Will be checking your blog regularly. Hope to hear from you.

    Regards,

    Hi All,

    I tried to convert the sample UIDemo project comes with Sun Wireless toolkit by changing the below properties in the build.xml




    Also changed the jar path to UIDemo.jar and finally was able to compile and got the UIDemo.apk in Bin folder of microemulator-2.0.4\microemu-android\bin , But when I installed this apk in Android Emulator and Device and tried to run the application.
    It did not run and it displayed the Title for some time and then nothing happend and blank UI got displayed. I tried the same steps with Games sample also. What could be the reason ?.

    There should be more information in the emulator logs. What's a error on the logcat console?

    khalif,

    As you can see in logs, the problem is missing example.pushpuzzle.PushPuzzle class.

    The group forum can be a better place to continue this discussion: http://groups.google.com/group/microemulator-support

    tropanxtig,

    That's exactly true. If your applet is contacting with the same server that was downladed from, then your applet doesn't have to be signed.

    Hi Bartek,

    with regards to my question above i have added the tag below:

    param name="URL" value="http://demo02.utiba.net:8082/jme/test"

    to the html file. But i still cannot connect by http.

    By adding this tag on the html does the emulator automatically know that the applet is downloaded from here and all connection here should be permitted?

    Any other info i need to add. my application is unsigned and needs to connect to http. as u mentioned since i will be connecting to my "home server" i wont' be needing the signing.

    Please help

    thanks

    tropanxtig,

    You have to manually specify the correct url inside the MIDlet code. Or you can use the trick explained in the last section on the page: http://microemu.org/applet.html

    RE: connecting by HTTP

    i did the following to no avail:
    1. add
    param name="microemu.accessible.host" value="http://mycompany.com/"
    to the HTML file

    2. add
    microemu.accessible.host: http://mycompany.com/

    to the MANIFEST and JAD file

    still i cannot get it to connect to my http server

    Please help badly needed

  20. Bartek TeodorczykApril 15, 2010 at 10:51 AM

    tropanxtig,

    You have to do the different thing. In your MIDlet, you have to call MIDlet.getAppProperty("microemu.accessible.host") and then use that URL to connect to the server.

    ReplyDelete
  21. UnknownApril 17, 2010 at 5:40 PM

    I did declare the url from varied location(jad, manifest and the html file), all does not seem to work.I have used the following:

    (1) code in MIDLET:
    String myurl=midlet.getAppProperty("url");

    connection = (HttpConnection)Connector.open(myurl);

    add this line in my html file
    param name="url" value="http://myserver.com:8084/test"


    OPTION 2) code in MIDLET:

    connection = (HttpConnection) Connector.open(midlet.getAppProperty("microemu.accessible.host));

    Add this line in mmy html file :
    param name="microemu.accessible.host" value="http://myserver.com:8084/test"


    both these scenario still throws a security exception error.

    badly need help guys. thanks

    Microemulator's guys ! As an user, i think that Copy&paste "to" and "from" OS clipboard could make a lot o things easer. As a non-US user, i think that "support for abnt2 keyboard" may be useful, too. Because "operamini/microemulator" isn't good enought to "email", for example. Then, in general, i use it for just browse. And to email, i use "OperaMobile for Deskop". But i love operamini inside microemulator. It is just so free of lags, etc. Good work.
