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
God Bless to all

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.

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)

How to compile using J2ME Wireless Toolkit?

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.

J2ME Wireless Toolkit Not Loading..

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.
You can find more detail at http://forum.java.sun.com/thread.jsp?forum=31&thread=145251
Thanks you for responding, dumb00.

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 Question/Error?

Hi!
I was previously J2MEwtk 1.0.1 and just downloaded ver 1.0.3 but found that the latter doesn't generate the JAR file automatically when I build a new app. I don't see additional settings required ... did I miss out anything or is there a bug with ver 1.0.3?
Pls advise. TIA!
Regards
swinging

Hi! Rob
Thanks for your prompt response. :-)
I think Sun's rationale was to make compilation modular and reduce the time taken for folks who just want to compile and test. The jar-ring is only necessary for deployment. I think this is a good idea actually.
But I don't understand why there's no Package button on button-bar ... there still lots of space on the button-bar! :-p

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!

Hi! It's great that you worked it out. I'm having problem with RetroGuard. When I ran out.jar, I got the following error:

I checked the contents of out.jar, and found that my classes were renamed to a.class, b.class...
I must have missed something. Can you tell me?
