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,
iamjenie

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 ?.

Bartek Teodorczyk said...

khalif,

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

khalif said...

Dear Bartek,

Bartek Teodorczyk said...

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

Bartek Teodorczyk said...

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.

DFH said...

I tried it with a Go Bible app.
After selecting Go Bible Menu| Preferences | Full Screen : On, MicroEmulator could not get back from Full Screen mode.

tropanxtig said...

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 said...

Hi Guys,

still cannot get my http connection to work

see above post

any help will be appreciated.

Thanks

Bartek Teodorczyk said...

DFH,

Issue database is the best place to report such a problem: http://code.google.com/p/microemu/issues/list

Bartek Teodorczyk said...

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

tropanxtig said...

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

Bartek Teodorczyk said...

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.

tropanxtig said...

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 can't Copy text on Opera Mini .. . why ??? and many problem in the text box when I input text .. .

Eagerbvr said...

Hi has anyone had any experience getting JSR226 (SVG) running on the emulator??

Cheers

Ed.

Bartek Teodorczyk said...

Eagerbvr,

I'm afraid there is no support at all for JSR226 (SVG) in MicroEmulator.

Christ The Last Hope said...

I cant download this application and java on my at&t samsung phone A837. Pls help me out

Christ The Last Hope said...

I need help on java download and installation

Bartek Teodorczyk said...

Christ The Last Hope,

It is not possible to run MicroEmulator on your phone. You can run Java ME midlets on your PC using MicroEmulator.

Bartek Teodorczyk said...

magicmumy,

Most likely you need to include the lib/microemu-jsr-120.jar into your classpath.

bilopo said...

hi Bartek Teodorczyk, thanks for sharing MicroEmu .. OperaMini perfectly runs on it but unable to perform downloads .. i can use the same JAR in my NOKIA and make downloads .. will there be any releases that this function will be available?

Bartek Teodorczyk said...

bilopo,

Here you find more details how to enable downloads:

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.

p3m4la5 said...

I am try opera mini 7, its work..

but how to copy paste from/to clipboard or something like notepad

Atox Gatal said...

Incredible!!! Thank You!!! Opera Mini 7.1 worked on this emulator.... It was an alternative way besides using KEmulator.... KEMulator doesn't work on my windows 7.. Keep up this good work... And I hope there
will be update for java games like Gameloft in the future.. :)

Alan Bazan said...

Ctrl+c in notepad
Ctrl+v in microemulator text field

Seun Adesanya said...

Nice work here, but this is funny because it doesn't run any app on my system anymore, even with the new version of java installed on my computer.
