install WMA RI into Sun one Studio

[Loh Ying Hui]

Hi All,
I want to use Sun one studio 4 mobile edition for developing wireless applications for Nokia j2me enabled phones . However, i have no idea how can i install the wireless Messaging API into it.
Anyone out there got any idea ?

Thanks in advance.

Adding WMA RI to SunONE IDE is not easy. The RI itself is just a JAR file that can be added to classpath. But to run it on an emulator, you have to pass many runtime parameters (see WMA page). I am not sure how flexible SunONE's native build and execution utilities are.
I just run ANT inside SunONE to take care of my build process.

hi there,
Can you tell me which WMA page should i refer to? Because most of the pages i read didn't tell bout the runtime parameter that i should pass. Second, where should i place the WMA jar file?
Thanks again!

You can download the WMA package from
http://java.sun.com/products/wma/
Download the PDF documentation and RI.
SunONE studio take every directory in your mounted "filesystem" as part of the classpath. So, just mount the WMA JAR file to your project "filesystem".
Or, if you can wait, I have an article discussing details of WMA in IBM developerWorks in Dec.

[Loh Ying Hui]

For instance, if my filesystem is under d:\myDirectory\MyPackage,
Where should i mount the WMA jar file ? Is it under d:\myDirectory ? The WMA i downloaded is a zipped file, so, should i load the other zipped file into the same dir as the WMA jar file as well ?
Yes, I will be hoping to read your article..and in the mean time, try to work this out.
thanx

Any other reference implementation Michael?

Ying Hui: You need to "mount" the JAR file in your "file system".
Ashik: There is only one "reference implementation". Device specific implementations are expected to come out when major device vendors come out with MIDP 2.0 devices (in Q2-Q3 2003).

IBM developerWorks finally published my tutorial article on WMA.
Enjoy!

[Loh Ying Hui]

Cool... Thanks a lot!

I have downloaded the sample coding in the document and I am using the Sun one studio toolkit to build it. Where should I specify the reference implementation's runtime properties ? I can't find any internal config file in the tool. And I am not running the application using command line..
Plz help. thanks.

OK, SunOne studio does have some problems with emulator command line options. Sorry, it just seems to be a limitation of the IDE.
That is why I was never a big fan of IDEs -- They automate a lot of things to make it easy for simple tasks. But when you need power and flexibility, they are often awkward to use ...

well, guess i'll have to go back to the manual way of running an emulator from the command prompt. :roll:
Another question i would like to ask, is it posible to run 2 emulators at the same time, one emulator sending a sms and another emulator receives it ? Thanks.

hi,
I received below error while trying to run the WMA tester source code. Is there any setting i missed out ? I've already added the required runtime properties in the internal.config file.
Besides that, i also have error while trying to access com.sun.midp.Configuration.getProperty(propName), the message i get is that there is no com.sun.midp.Configuration package.. What is wrong actually ?
Plz help! Thanks in advance.

Yes, you can run two emulators on the same machine.
As of the errors you had: It seems that they are all related to the config file where your specify the command line options. Maybe you should consult Enrique's article for more info ...

I can finally run the application.. I guess the error i am having is the wireless toolkit i m using is a 2.0 version and there's some security problem.
Micheal, in your article you mention about the MIDP 2.0 AMS (Application Management Software). When a registered connection comes in, the AMS invokes a corresponding MIDlet to handle it. When the AMS picks up an SMS incoming message, it will first buffer the message and then trigger the handling MIDlet. The MIDlet can read and delete the message. Is this posible with the wireless toolkit 1.0.4 ?
thanx.

J2MEWTK v2.0 emulator does not allow you to override javax namespace. But the WMA RI does provide classes in that namespace. So, unless WMA is somehow bundled into the WTK in the future, you have to obfuscate the application (change class names etc.) before you deploy.

No, The PUSH architecture is only available in MIDP v2.0. The 1.0.4 emulator would not work.

That's too bad.. , is there any other emulator you would like to suggest ?

Yes, you can run two emulators on the same machine.

Hello there,
I've try doing with 2 emulator and it works. What about running two emulators on different machine ? Is it possible ? Where do i set the ip address ?
Thanks !
