I waisted full day looking in the CVS... could not find the right build....

does any body has a simple SWT.jar and a SWT*.DLL I can just use???
and please don't send me to the CVS again...

Scroll to the bottom of the page - there are two possible Pocket PC
downloads in the SWT Binary and source section:

Windows CE (ARM PocketPC) (Instructions)(http)
(ftp)swt-I20030422-win32-ce-arm-ppc.zip (md5)
Windows CE (ARM PocketPC, J2ME profile) (Instructions)(http)
(ftp)swt-I20030422-win32-ce-arm-ppc-j2me.zip (md5)

The pocket PC stuff will be available as a separate download in all future
Eclipse downloads.

The J2ME version of SWT can be used on top of CLDC. MIDP is itself on top
of CLDC but also includes its own UI and event model so it's probably best
to just use the CLDC profile to develop SWT apps.
I am using the j9 arm pocket pc VM. Feedback about the Creme JVM is
interesting.

You said you use J9 on the PocketPC. do you use WSDD as IDE? or just
Eclipse?

I don't mind using J9 on the pocket PC but I can't the right configuration
to have both serial comm and SWT GUI.
have you ever done this?

The j9 CLDC library provides a serial port connector which should work on
PocketPC. I don't have a serial cable on mine, but you can post j9, WSDD
and serial port questions to this newsgroup.
news://news.software.ibm.com/ibm.software.websphere.studio.d evice-developer

To use SWT with j9 on a CLDC profile one method which can be used with
either Eclipse or WSDD is to:
- install j9 with the CLDC classes.zip (ask newsgroup above - it comes
with WSDD)
- install the WinCE swt.jar and native library for J2ME. You can get it
from the Eclipse download page. e.g. a direct link to a recent integration
build is:
http://download.eclipse.org/downloads/drops/I-I20030429-2003 04291456/download.php?dropFile=swt-I20030429-win32-ce-arm-pp c-j2me.zip
It contains the swt.jar you need and the dll.
- create a shortcut file MyApp.lnk such as:
142#\j9cldc\bin\j9.exe -jcl:cldc:loadlibrary=swt-win32-3002
-Djava.home=\j9cldc -cp:\j\swt.jar;\j\myapp.jar MyApp
(adjust to your own location of j9, swt.jar and your application myapp.jar)
- copy this shortcut file and click on it from the Ipaq file explorer.

The main differences with J2SE are:
- The command line tells the j9 VM to use the cldc classes.zip and to load
the swt native library (since there is no System.loadLibrary under CLDC,
it has to be done by the VM)
- Use a swt.jar for J2ME. This jar does not use non CLDC api such as
System.loadLibrary etc.

If you have problem running SWT apps using j9 cldc, please post back
details on the issues.

Chris,
I can't seem to run the project on neither Windows or Pocket PC.

So here is what I did:



1.. I'm using WSDD 5.5
2.. Source code is attached.
3.. Created a simple J2ME project (jcl:cdlc) that uses SWT (source code
attached.)
4.. Added SWT jar file from eclipse
swt-M20030430-win32-ce-arm-ppc-j2me.zip to the project (in the Java Build
Path Properties Dialog)
5.. Added the following to the VM Arguments on the launch configuration
Dialog:




1.. -jcl:cldc:loadlibrary=C:\apps\PowerLOC\wsdd\cdlctest\Lib\swt -win32-2133.
dll ( The DLL I'm using here is from swt-M20030430-win32.zip)
When I run the project I get the following error:



"<error: unable to load
C:\apps\PowerLOC\wsdd\cdlctest\Lib\swt-win32-2133.dll (Not found in
com.ibm.oti.vm.bootstrap.library.path)>

<warning: unable to load j9cldc20 (JVM_OnLoad failed)>

Internal VM error: Failed to create Java VM"







--- Trying to run the application on Pocket PC -



1.. Attached is the Link File I created:
2.. When I run the project I get the following error:


WARNING: The command line argument "-cp:" has been deprecated.

WARNING: Use "-classpath <path>" or "-cp <path>".

> --- Trying to run the application on Pocket PC -

1. Here is the link file I used to run your test case.
142#\j9cldc\bin\j9.exe
-jcl:cldc:loadlibrary=\j9cldc\bin\swt-win32-3002.dll -verbose
-Djava.home=\j9cldc -classpath \j\swt.jar;\j\Main.jar cldctest.Main

- make sure the swt.jar is the one coming from the J2ME zip file. I got
errors similar to yours (IncompatibleClassFileError...) when using the
swt.jar for J2SE. I used the one coming with:
http://download.eclipse.org/downloads/drops/I-I20030429-2003 04291456/swt-I20030429-win32-ce-arm-ppc-j2me.zip
- do not specify the classes.zip in the -classpath option. j9 will find
the correct one with the flag -jcl:cldc
- if this still causes trouble, post back the output of the j9 console
(make sure you added the -verbose flag in your link file).

For good answers on WSDD and how to set it to use third party jars/native
libraries like SWT, please ask on the WSDD newsgroup. I'll try WSDD5.5 but
they will probably provide you with a faster answer.

Hello,
please tell how can I download WSDD.
There is a link to IBM web site but it does not work anymore.

Thanks
