I've been studying Java with the Open University and would like to put into practice some of my newfound knowledge on the mobile side of things.
Can anybody help me get started by telling me which configuration I should be using with regard to CLDC/CDC-MIDP, are there any JDK's for the Touch HD etc?
I have tried searching but to no avail so far so would appreciated your help.
Also, is there a decent Java compiler that operates under WM6. As that would be novel to play around with too! I currently use NetBeans on my pc.
Regards
Gary
Java on a mobile device = J2ME
There are plenty of Java VM for Pocket PC (check this thread). I think JBed (found in most blackstone ROM's including stock ones) is the best. It has severe limits but it is the best you can get on blackstone. For developement you can use your PC with Sun WTK 2.5.2 (it is supported by Netbeans).
There are no decent java compilers that run directly on PocketPC.
As your first app can you create a D-Pad in java to run skymobile????

Java ME : JBed or JBlend, choose one of them, both work great.
Java SE (Yes Desktop-class Java): MySaifu - http://www2s.biglobe.ne.jp/~dat/java/project/jvm/index_en.html
As for the JDK part (I mean the javac compiler and other tools), I do not know such a package yet. However, you can make javac work with MySaifu with a tools.jar file copied from standard JDK (1.3 or older probably).
Hope this helps
Java development with JVM for CDC
Thanks for your help guys.
I've managed to ge set up and have managed to create my first Midlet and run it on my Blackstone via JBed. I've used NetBeans 6.7
However, that is CLDC/MIDP, but when I try and install CDC creations JBed will not install it because a Midlet name is missing. Is this because the stock JBed does not support CDC. I have tried to find out but it is not perfectly clear and I will have to pay for a JVM to test my theory out if nobody can advise!
Thanks for help

I'd seriously look at JavaFX, sun released a beta of it the other day.
I really like it, it works well on the HD from my limited testing
http://javafx.com/downloads/windows.jsp
One slight flaw with the current version is that it wants to get network address even when try to search for local jar/jad on storage.
but setting it as default file association gets around that one..
JavaFX
Downloading as I write....
Thanks for your advice I appreciate it. As you may know, as a newcomer to development of JME it is so complicated to get started due to all the configurations so any pointers at this stage are very much appreciated.
Thanks
Gaz
OK, I have JavaFX installed on my HD and it works and I particularly like the calculator example app included with it. However, I still cannot get my CDC app to install. It says "Cannot install application because critical information is missing from the application file (.jad). I thought CDC used xml files and not JAD for descriptions. Am I wrong or is something to do with my platform/deployment configuration?
I cant see a jad file in the deploy folder either. Is this an error.
Thanks
Gaz
Nope, you still need the JAD descriptor file.
It's plain text file, just find some on the internet, open it with text editor and alter some of the properties in there, it's really easy.
Don't forget to change the path to your JAR archive - the best way is to put there just simple JAR name and copy the JAD to the same directory as JAR.
Thanks Pepcza,
I'll try that, just a thought though, if you still need a descriptor file (in this case .jad) why does'nt the Netbeans deployment process create it along with everything else? It does when creating CLDC platform apps!
Gaz
JavaFX
I think we should concentrate on this one. Youtube videos are working in bolt browser using Javafx. If only it would be a bit faster, It'll throw Jbed out of the window.

Hi,
I'm very new to programming, but I will do anything to make the eten bluetooth manager function correctly (thanks to vijay to have uploaded it to us) I think this will be the ultimate ms stack upgrade..
BUT
I searched a lot, and still haven't found anything simple that simply debug those bt manager files (exe and dll)
Anyone know anything good? Usable? Practical? :lol:
Any help is welcome; I've already looked to VB6 app but is way too complex.. I only wan't to debug, nothing else (for the moment )
Cheers, MocciJ
Unfortunately the only widespread pocketpc debugger is IDA (trial version available).
If you only need to get access to resources etc, check out Resource Hacker etc. Or use the Visual Studio resource viewer.

Hello All,
I've been looking over various board (and Google) but found no answer to this particular question. I hope you can help.
I have an employee who has just got himself an XDA orbit. This has come with MS .Net Compact Framework version 2 on it. We use some device software that has been written for version 1. Now; version 2 is supposed to be completely backward compatible but it turns out that is not the case.
What I would like to ask is:
It appears that you can have multiple versions of the .net compact framework installed yet the MS installer will not install because it detects the newer version. I am not familiar enough with .net on these devices to know any way around this. Is it possible to retrofit version 1 at all? You advice would be much appreciated.
I would really like to help this guy out.
I guess this is because Microsoft thought they would be compatible. I would try to get another installer for CF1. If there is nothing newer than the one you have, try editing the installer. The cab-Installations are defined by xml files and are quite easy to read and edit. It shouldn't be a problem to remove the check of the newer version.
Tell us if it worked :-D
Ok...
I have the newest installer for .net CF V1 SP3. That's the latest one I can find on the MS site - without going to Version 2. I've unpacked it and I am now sitting looking at a folder full of CAB files.
I guess one of the questions I need to ask is whether it is possible versions of >net CF on the Artemis? If it is, are there any caveats?
And how do I know which CAB file to use?
I should explain that I am new to field of XDA modding so I don't really know all that much about how the OS works. This is a little project that will help a friend out (he is techincally incompetent) and give me a bit of extra knowledge (right now I feel technically incompetent...).
I'd try it that way: run the installer with the ppc disconnected. Then look into the "program files\Microsoft Activesync" folder which cab you can find there. Maybe it's more than one depending on your CPU. Extract the cab and edit the xml file.
CF1 SP3 is built into the ROM of WM5 so installing it again is just wasting your precious storage memory. CF2 SP1 can be installed to your storage card. CF2 is backwards compatible and can run CF1 applications, but since all WM5 devices have CF1 built in when you run a CF1 app it actually runs under CF1. You can force it to run under CF2 by placing a config file in the applications directory.

The config file is explained here:
http://blogs.msdn.com/davidklinems/archive/2005/11/09/491113.aspx
@indiekiduk: without having read your links; are you sure about CF1 is installed on the device?
I tried the version checker of the hitchhiker website ( http://www.kasuei.com/hitchhiker/ ) and it says ".NET Compact Framework Unknown (2.0.5238.0)" seems to me like version 2.*.
I have not installed any other CF onto my orbit.
correct me if i'm wrong please.

This is simply not true. The Orbit comes with SP2 installed and has never had SP1 installed - not in the ROM on the XDA I've seen.
The Orbit comes pre-installed with CF2 - I have seen this with my own eyes. It is also NOT completely backward compatible. Even the CF .net team admit this - there are always caveats when microsoft say something is "backward compatible".
I don't want to force it to run under SP2 - because it IS running under SP2 already.
Can anyone tell me which CAB file I can use to install another version of .net CF? And if it's even possible to retrofit CF v1 on the Orbit?
You could try changing the value under HKLM\software\microsoft\.NETCompactframework - to try and fool said program to believe you have CF1, CF2 programs may not work but worth a shot.
Hi,
I was wondering if there is a jvm for wm 6 which supports xlets. They are part of the CDC toolkit...
I don't want to have to use midlets as it is quite a big process to convert an existing swing program into a midlet.
Has anyone been able to do this?
Thanks
Edit: I just discovered that esmertec jbed is supposed to support cdc and should support xlet i guess...
but when I run my xlet all I get is a 'File error (???)'
I also know that others have this problem as was posted here:
http://forum.xda-developers.com/showthread.php?t=339579&page=7
But I don't think they were resolved.
Bump:
Has no one ever tried to get xlets working on their phone?
Ok, I found a java manager called CrEme.
It's great it lets you use any standard CDC java app which supports standard swing/awt. So you can instantly port any java app directly to your phone.
XLets/Managed aplications still don't seem to work but given that it runs normal apps, Im not too worried
I don't have any links for it but I've got the files if anyone wants them.
dear user, what does that all have to do with HRDF (Hermes ROM Development Forum)? why don't you ask this kind of questions in GDs (General Discussions)?
I'm going to start with why, then how.
Why: I use the open source SharpDevelop to write Windows Mobile .NET applications. Some of the managed libraries that are included in Windows Mobile are not usable without the Windows Mobile SDK files. Microsoft's SDK Installer checks for Visual Studio, and if it not installed, will NOT install the SDK.
How: Download the SDK, open a command prompt, cd to where the SDK was downloaded to and type (making appropriate changes):
Code:
msiexec /a "MSI File.msi" /qb TARGETDIR="Full path to target directory"
For example, lets say that the file is called "WM6 SDK.msi" (which it is not), you downloaded it to "C:\WM SDKs\" and you want to extract it to "C:\WM SDKs\WM6 SDK\", you would type:
Code:
cd C:\WM SDKs
msiexec /a "WM6 SDK.msi" /qb TARGETDIR="C:\WM SDKs\WM6 SDK\"
The DLLs you need to add a references in your project will be under a folder called Designtimereferences
Anyone find this useful?
heyy thanks i found this useful...havent tried it yet, but didnt wanna go about downloading and installing VS if i dont want/need to
thanks man

No problem ... Thanks for the feedback.
cool!
Ultracool Man!
thanks for sharing the information .... no doubt it is useful to alot
Interesting! Anyone know if this enables the SDK to work with Visual Studio Express?

I doubt it ... I use SharpDevelop. I have a legal copy of Visual Studio 2003 + 2005, but I use SharpDevelop.
SharpDevelop
Does sharp develop support Compact Framework 3.5?
What are some advantages to using this?
I normally develop with visual Studio 2008 Professional with the Window Mobile 6 SDK.
Wish I would have know about this sooner.
2008 Standard does not support windows mobile development and pro was kind of spendy.
2005 standard supports it.
<slight rant>
Why microsoft? Why would you require pro to make apps, when you need to gain market share. The other platforms are growing because of the availabilty of apps.
</slight rant>
Sharp Develop DOES support CF 3.5, but you need to install .NET CF 3.5 and .NET CF 3.5 Power Toys on the PC to use it ... See Compact Framework on SharpDevelop Wiki.
Hi, I come from China.
These days, I get a problem.
That's my title said. How to use DirectDraw on Windows Mobile?
I found a file named "ddraw.h" in WM6 SDK folder.
But it is only used by c++.
I want to use DirectDraw by c# or vb.net.
Is there any idea?
Better to be a library...
Thank you!
[My English Doesn't well, Sorry.]
如果你会中文那就太好了：
这些天我遇到了一个麻烦，就是怎样在WM上使用DirectDraw
我在WM6的SDK里找到了一个ddraw.h文件
但是那是c++用的
而我是使用vb.net的
有没有办法呢？
最好是一个类库……
谢谢……
Anybody know it?
How can u draw your UI?
Did you check out http://forum.xda-developers.com/showthread.php?t=487354 and http://blogs.msdn.com/b/marcpe/archive/2006/03/03/542941.aspx which it references to as well?
The developer there seems to have similar issues and is using C# to access DirectDraw (by using a specially compiled dll.)
Since I'm no WM developer (yet), I can't help you out any further... but I'm sure some searching even on this forum alone should be able to provide you with enough information to get you started.
Oh and... welcome to xda-developers!
Thank you for your reply Art4.
I know that`s a solution. I tried to compile ddraw.h to ddraw.dll, but failed.
I'm very bad in c++, only VB.Net...
.h is just header which you include in your project (C++). The target .dll is already compiled somewhere in WM or the SDK. In that .h you can see what functions have which parameters and you can via interop and marshalling put them in your C# (or VB.NET) project and call them from there.
