YSE I can Run JAVA in my Clie NX80 COOL!!

[naren]

I was exploring some deeper stuff like developing own Java applications and running them in Clie, YES!! I can do that with great support of Sun's J2ME tool kits. I can I downloaded some examples and games from sun site and played nicely:).

MIDP 1.0 (Mobile Information Device Profile) is the API Sun provide for developer to write cool games and applications for MD and PDA. PALM 5.0 runs these apps nicely.

In the begging, just download some examples and install in Clie here is the link -

If you are a software developer and know Java programming language, you can download developer's kit, POSE (PALM OS Emulator) and enjoy writing your own stuff. The Good news is that Clie armed with great processor and PALM 5 OS provides great performance to run Java.

I am thrilled, I can develop some and make full use of my Clie!!

Thanks,

Nice... I'm a Java developer and have created many programs in Java. I'll have to check this out later tonight.

hi, it works on my nx
but can i converter java on some websites to prc?

[BOJI4OHKA]

Do you know if there is a C++ one?

[naren]

You can always do developement in C/C++ too, you have to get the PAML API's and Code warrior devloper suit. They have v9.03, try it.

such as what ??

[Forest_Noggle]

Is this the same Java for cell phones and GSM applications?
If so, I am not a developer, but have some ideas.

MINEX?

it sounds great!
let me try!

[aptyk0]

can I load the java of a website to my nx?

Nice, I managed to get it working... suprisingly, it was pretty simple. Just load the MIDP.prc to your handheld, and you have a Java VM going. Too cool. The only problem I see is that you need to have the applications installed on your internal memory.

foest_noggle, in a nutshell, it should be the same. Generally, java is platform independant so you can usually get applications running on just about any platform provided that you have all the right libraries.

aptyk0, in theory, yes. I haven't dived into it too much, but they package provides some kind of converter code to translate a java application on your PC into a .prc file. I'm not sure how it works yet, though, but rest assured, I'll look as soon as possible.

If you write a Java program and convert it to a PRC to be installed on the handheld, then do you need to have the Java VM installed to run it?

[minex]

Thats correct, addict. I dont think the converter includes the VM on every prc you convert, unless I am missing something.

what i meant was, does a PRC written in Java require a JVM, or can it run on a CLIE with no JVM installed (like other PRCs)?

[minex]

I thought I answered that. Let me try again. Yes, the prc requires a JVM... I believe thats what the "Java HQ" (MIDP.prc) file is. As I said in my last message, I don't think the JVM is packaged with the .prc unless I am missing something.

[addict]

Okay. got it. I was hoping that I could write a program in Java, convert it to a PRC, and install it on my CLIE with no JVM installed (at all, ever). The reason being that the JVM takes up valuable memory and that's undesireable to me. Personally, I think that's the biggest drawback to Java-based mobile apps. There aught to be a way to convert them to a format that does not require a JVM (IMO).

[minex]

I Agree that the JVM can be a pain in the butt, but there are also merits in having this concept of a virtual machine too. To me, I just look at is as another .dll for or some other library. ie, don't you need mathlib.prc to run several math based applications? I have to admit that I was a little disappointed at the fact that the JVM needs to be on the internal drive -- it takes up a whopping 500K. I tried using ZLauncher's feature in moving it to the MS, but several of the Java Applications stop working, some don't. *shrug*

I guess it would be nice in the future if Sony Clie models came with the VM bundled in flash (sort of like the Zaurus models).

Minex:
if I give you some ideas, are you intrested in writing the app?

IE: there is a conversion app that is PC based for Nokia phones. Why not write a Palm OS version to replace the PC and so that with the combination of a Clie and Nokia phone, it is completely portable?

the above link explains a lot of my idea.

foest_noggle, there is a conversion app that takes *.jar files and converts them into .prc files that is bundled with midp4palm bundle. You just need to make sure that the jar application uses the midp api, which I assume nokia phone apps probably do.

I am writing this real quick, so maybe I misunderstood what you are saying. I'll look at it a little deeper later.

[Forest_Noggle]

Cool!
Sounds great.
As I am not a programmer, what I am suggesting is actually 2 things:

1 replace the PC end with my Clie via new software on the Clie to make this possible.
2 create apps for the cell phone to replace those of the Palm OS where it makes sense. ( I don't really know what those are yet, but I have constant ideas pop up and think, "wow, that would be really cool if I could do that with my GSM WAP phone."

Thanks, Jay
