Create J2ME application at iPAQ Pocket PC/PalmOS?

Hello everybody.
I would like to develop an application(J2ME) that will be run under mobile phones and PDAs. We were thinking to develop this application at mobile phones that have Symbian OS(7.x), PDAs that run PalmOS and also WinCE.We wondering if we can develop just one J2ME application, and run it through Mobils(SymbianOS),PDAs(PalmOS/WinCE).The application will be big enough.
Of cource, we are not thinking to develop this application using java libraries which are specific for each of the above platform(e.g. flashlight() for NOKIA phones).Just the general libs that are supported by J2ME API.
If anyone has developed a J2ME application at iPAQ( and the problems he faced or not), I would really appreciate to give me some suggestions-guideliness, before I start developing.
However, it will not be a problem for PalmOS devices.(MIDP 2.0 supports that)
If you also think that some problems will be arise by PalmOS, please give me your help.
Thank you.

Hello and thank you for your help(need j2se and not j2me for iPAQ).
I downloaded the Jeode, which can be useful to run Java Applets and it can be also used as JVM.My iPAQ is quite old(3800) so I can not use the creme VM.
However, I have laready run an Applet and j2se standalone application.It seems that works ok until now.
On the othed hand,the PalmOS application must be implemented onto J2ME as far as I know.Am I right?

Can J2ME or Java application run on Pocket PC?

Hi everyone,
I got myself recently an iPAQ, I was wondering whether I can develop Java applications on my PC and run it on my iPAQ for usage?
What's needed and the procedure to implement this?
Thanks.
regards,
Aldrick

You can create J2ME applications in some IDE like Websphere Device Developer. Then you need to configure j9 on your PocketPC and build and run the application on the device. All these steps can be done easily in Websphere Device Developer (WSDD)

Can j2me application run in any pda platform?(from newbie)

dear all,
i am a newbie in this field. i just to ask is it possible for a j2me application run on any pda platform?for example, palm OS, window CE, synbian, and etc.
what do i need to create j2me application?
best regards and cheers

Hi,
if you use standard APIs (from MIDP 1.0, 1.0a or 2.0 specs) and run your application on device supporting this set of APIs you'll have no problem. For creating J2ME appliaction you should get J2ME Wireless Toolkit in the first place. Furthermore some IDE can be used (Sun ONE Studio, netBeans, Eclipse, JBuilder).

How to Create trial version of my j2me application??

Hey..
could please anyone write a short note on safest way of creating a trial version of my j2me application?? like i want to limit the number of tries.. like say 25 tries..
are there any applications that do this.. or could u suggest good coding methods.. ??
thanks a lot!

rakesh.pachava wrote:
Hi,
You can use the Record Store implementation to count the number of tries.
But if once the app is uninstalled then the record store is also lost.
If you want you can use the File Connection API to write to file system.
This asks for user permissions.
Regards,
Rakesh pachawa.yes.. this is the method im using.. & i dont want to access the File System directly.. cause i want maximum compatibility. I don't mind re-installing the application causing the trial to be re-started.. thats fine.
but i don't want someone to be able to crack the class files by taking out the code which checks the Record Store..
how are j2me applications normally cracked pls??

Creating a HTML page from the J2ME application

Hi,
I am developingan application in J2ME. Can anyone of you out there, help me whether there is any way I can generate a HTML page from the application.
I have the data but I don't know ho to create a HTML page from a J2ME application.
Any document or any code will prove handy.
Thanking in anticipation.
Ashish

When you say that "you have the data" you mean that you have HTML code data(<html><body>Hello World</body></html>)? If yes you should create an algorithm that "read" html tag and display text in the appropriate layout/font/size/color...
A solution could be simplify your HTML code (server side), so you can easly "decode" and display text.

Creating Demo J2ME application

Hi friends,
I have created one J2ME application. It is working fine.
Can anybody tell me waht I will have to do if I want to make demo of it.
Means I want create demo of that application for certain days say 10 or 15.
After that much days softwrae will not run.
How can I achieve this?
Plz I need it urgently
Thanks in advance

The problem is that actually I am one of Lync administrators and I need to decide what is most important for Lync infrastructure. What I found in a meantime is "Health Rolllup Diagram" module in Lync server 2013 Management Pack Guide, part of it
below:
A Lync Server pool can contain multiple individual Lync Server systems (with more than one Lync Server server role, Lync Server service, and Lync Server component). Therefore, the failure of an individual server or component is less critical to the overall
health of the Lync Server pool, because other servers in the same pool can provide the application service to the client. The health will roll up on a percentage level to the Lync Server pool.
The Lync Server Pool Watcher performs synthetic transactions against a Lync Server pool. Consecutive failure of one or more synthetic transactions (a process known as the
consecutive polling interval) will roll up the critical health state to the pool level (worst of any synthetic transaction), as shown in the following diagram.
Note: The Lync Server Port Watcher and global Simple URL Watcher do not roll up the health state.
Using this information I think that I should start with using LS site class for monitoring Lync servers (Mediation and FrontEnd), am I right? But not sure what I should do with the rest of infrastructure, SQL server, Office web apps and
the rest

Opening a web page through my J2ME application.

Hi All,
I am creating a j2me application, that has to connect to the server online and open a page on that server, and then upload a file at a particular location in that server.
I am using Nokia 6681. I was exploring it, but since I have very less time, I am posting a query here also.
If this is possible (opening a connection with a server - I have the IP address of the server and also the path to that page), and display that page on my cell phone from within the j2me application.
Is this somehow related to JSR-172 (Which is not supported on Nokia 6681).
If this is not possible this way, Is there any way I can upload that file to the server from within the application.
Urgent help is required.
Thanking you in anticipation

Xml Push Parsing in J2Me applications

Hi all,
I would like to use Push parser in j2me application.Can u please tell me how can i use sax parser in mobile application.Because when i included "jaxp-api.jar" in mobile application,it gives an error "FactoryFinder class not found".. So please tell me how can i overcome this error or any other push parser available for J2me applications.
Thanks
Regards
Sourab

Please review this article.
http://developers.sun.com/techtopics/mobility/midp/articles/parsingxml/
There is a link to a push parser mid way through the article. If you search "push parser j2me" you should be able to find others.
If you still are not able to find a push parser you could create your own. How complex is the xml you need to parse?
I created an example called y!p! some time ago that uses a push parser to parse Yahoo's Image Search web service. (http://developer.yahoo.com/search/image/V1/imageSearch.html)
You can download the example src code. For a more complex example you could look at w!k!. It uses a push parser to parse html wikipedia articles.

Problem creating J2ME web service client

Hi,
I am using netbeans (5 and 5.5 beta 2). I have created a web service which works fine. I also created a regular web service client as a standalone application which also works fine and connects to my web service with no problem.
BUT, when I want to create a J2ME web service client (under a J2ME application) I have to locate my WSDL file. but the wizard shows me the error "WSDL file does not contain port information".
By looking at the WSDL file I can see that port is created - or maybe I'm wrong.
piece from WSDL file:
<service name="myServiceName">
<port name="myServiceSPort" binding="tns:TranslatorWSPortBinding">
<soap:address location="myURLLocation"/>
</port>
</service>
Please note that I have replaced the actual values in above piece
I tried to use wsgen manually but it didn't help.
Can anyone help me in generating the correct WSDL format as J2ME web service client expects?
Thanks a lot,
S.

well stubs are generated separately using WTK 2.5 stub generator but the problem is with the WSDL at this point.

VM Error installing J2ME Application

i am creating a J2ME application that make a HttpConnection.
I made a lot of tests in WTK and it worked fine, but when I tryi to deploy it to a iden phone Motorola i85s,
and the application is being installed, occours a VM Error.
I connected the cel phone by hyperterminal, to debug, and the following message was shown when the error appeared:
Fatal error: Unresolvable reference encountered in class services/a
I continued trying to resolve the problem and I perceived that the following line is the reason of the error:
OutputStream os = c.openOutputStream();
c is a HttpConnection object.
When i remove this line of the code, the deploy works fine... but my application needs this line to work....
Have anyone an idea about what could be happening?
Thanks a lot.

Hi,
Check with your device manual if your device implementation supports HttpConnection.

J2me application with ejb

Hi,
i wish to access an ejb from my j2me application.
Can I create stub for that ejb and use it with my application?
or
shall I use a servlet for the access of EJB ?
I need a value to be returned from a function in my ejb. If i am using servlet then, i should return any xml file which contains the value returned from ejb function. this xml file should be sent to the client.
Please help me.
Thanks in advance

If EJB like RIM? I'd guess not, you would have to have a HTTP/servlet go between.
