Java Micro Edition

I am developing an application for the Palm OS, I am using Suns Studio ONE micro edition. I am having a problem setting the size of an image, I add the Image to ImageItem, ImageItem is a subclass of Item which has a setPreferredSize method, but it tells me it does not recognise the method, According to the API this feature has be included since MIDP 1.0. I also tryed setting the size on a Item object but got the same error.
If there is anyone who can help I would be much appreciated. Or if i am asking this question on the wrong form let us know
Thanks

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:
www.ewesoft.com
does anyone have experiences with it?

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?

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.

Java micro editions problems

I just installed the latest sdk (again) and all the appropriate packages to build micro programs.
All my environment settings are correct (I'm almost postive)
but when I try builing a .java file from the j2me wirlesss toolkit I keep getting the error:
In order to compile you need to use the full j2se sdk.
I HAVE IT!!!
What could be the problem?
I have reinstalled the wirless toolkit about 5 times now. Please advise.

its obviously not seeing your SDK...
have u installed the J2SDK in a non-default place?

Java Standart Edition 6 vs symbian

I noticed that the nokia n8 has Java Micro Edition, but there is no Java Standart Edition. In all android phones installed Java Standart Edition. For Java Micro Edition is the ability to write only small, minor program. When will be added full support for Java Standart Edition? 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.

Using CLDC Sun Java(TM) Micro Edition SDK 3.0 EA with netbeans

Hi ,
has anyone stumbled upon this - I just installed netbeans and Java(TM) Micro Edition SDK 3.0 and am trying to work with the examples of the sdk inside the netbeans , but when I open them I get the message : "Problem - the project uses platform CLDC Sun Java(TM) Micro Edition SDK 3.0 EA", but it was not found. Create platform named like this - I tried to do it , but it doesn't help.
Is there any way of overcoming this?

Ok , I found the solution.
I installed the Sun Java Wireless Toolkit for CLDC ver 2.5.2.2_01 directly (not as part of the SDK 3.0) , then added new platform and a new project configuration
according to the new platform.
In case someone else stumbles on that....

Bad installation of Java Platform Micro Edition SDK 3.0 - Can't uninstall

Hi,
I tried installing the Java Platform Micro Edition SDK 3.0 tonight and it didn't work (I guess the thing doesn't like it when you're running Win7 x64 with the latest JDK for some reason...). Anyways, it installed fine but on first run it got stuck at the nag screen with IOExceptions, etc. and never finished starting. So I decided to uninstall and guess what? I can't uninstall it because it tells me it can't run the uninstaller program since it can't load a win32 dll on a 64-bit machine...
So I resorted to deleting the folder and running a registry cleaner :/ However, so I can properly clean things up, I'd like to know where else the SDK put files or dlls and which ones.
Thanks for your help!
-LordPhoenix

I'm having exact the same problem, but I'm using Vista x64.
I tried to uninstall x64 version of the Java SE SDK and installed the x86 version instead, but it didn't help :/
So could please anyone post a solution to this.
EDIT: actually I at least managed to uninstall it using the SE SDK x86.
But still, is there any way to use Java ME SDK on Vista x64?

Uninstalling Java (TM) Platform, Micro Edition Software Development Kit 3.0

Hi,
I have installed Java (TM) Platform, Micro Edition Software Development Kit 3.0 EA, and now I want to remove it, however, when running the uninstaller I get a message about the "Java ME SDK is running. Please close Java ME SDK window and try again."
There is no other Java ME SDK running, I have even tried this in Safe Mode, but with the same error message! My guess the problem is that the installer think itself is the Java ME SDK.
Do anyone know how to solve this and uninstall the ME SDK?
I'm running Vista business, 64-bit if that helps.
BR Psy

It's strange that there is not any related processes. Have you tried to remove sdk related folders from your home?
Looks like it's platform dependency issue. Actually 64-bit is not declared as supported by SDK.
http://java.sun.com/javame/downloads/sdk30ea.jsp#install:
Required Software
* Microsoft Windows XP or Vista 32-bit with recent service packs
* Java SE Development Kit - JDK 1.6 or higher
* Apple QuickTime player (required to play AMR media on Windows)
I can suggest you to remove it manually from installation dir, <your_user_home>\javame-sdk, <your_user_home>\.javame-sdk and clean up registry.

Java Enterprise Edition Installation Issues

Hello
I am trying to install version 8 of the Java Enterprise Edition software but I am experiencing 2 errors. Sometimes I get a message that it cannot find the jre and now the jvm. I have JRE_HOME and JAVA_HOME defined. When this happens after the path page is done, I get a dialog error message with just an x in it. The other error happened once after defining the variables with an out of memory error. I have 2 gigabytes of memory,
I need some help.

Enterprise Edition -- that's the one you pay a lot of
$$ for, right? I would think those $$ entitle you to
telephone support, or am I wrong?They have an enterprise trial that allows you a free 30 days (full functionality).
I personally have not had any problems with it. (WinXP, RedHat 9.0)

Is anyone else seeing the same behavior in the downloads?
