I need to print simple text to a bluetooth linked printer. The printers
should be discovered by the Pocket PC operating system.
My application run on a Pocket PC Windows Mobile 2003.
I receive the error message "UnsatisfiedLinkError" when i call
pDialog.open()

PrintDialog pDialog=new PrintDialog(this.getShell());
PrinterData pData=pDialog.open();

Complete error message:
Exception in thread "main" java.lang.UnsatisfiedLinkError:
org/eclipse/swt/internal/win32/OS.PrintDlgW(Lorg/eclipse/swt /internal/win32/
PRINTDLG;)ZUnsatisfiedLinkError

I think the SWT print packages NATIVE implementacion is missing in the dll
3064 for that operating system , is that true?
I need to resolve this problem urgent, please, can you help me??
Do you know another way to print text from the Pocket PC to a bluetooth
linked printer?.

Thanks
Diego

Hi,

I am not familiar with the Pocket PC but I might be
able 2 give you some idea...

The UnsatisfiedLinkError is thrown when the swt
dlls cannot be found in java.library.path
You can put the dlls on the system folder on your
OS or better yet, put it in your lib dir and then
add a VM option:
-Djava.library.path=lib
in your run configuration...

Hope I gave you some idea...

Gud luk..

Thanks glenn for your response.
UnsatisfiedLinkError is thrown too, when a native method implementation
cannot be found in the loaded swt dll.
I tried your two options:
1)put the swt dll in the \Windows folder(it's the system folder for Windows
Mobile 2003)
2)add the VM option in the run Configuration:
"-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
Card\immapp\WebServicesME.jar" -Djava.library.path=\Windows
and
"-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
Card\immapp\WebServicesME.jar" "-Djava.library.path=\Windows"
and
"-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
Card\immapp\WebServicesME.jar"
"-Djava.library.path=\Windows\swt-win32-3064.dll"
and
"-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
Card\immapp\WebServicesME.jar"
"-Djava.library.path=\Windows\swt-win32-3064"

No way, the problem is still there. I receive the same error message.Then, i
think the print native methods implementation is missing in the swt dll.

Ah yeah.. That's one reason for UnsatisfiedLinkError.
I dunno, but there really are methods in SWT that aren't implemented
in the DLLs. One way to telling if you are invoking a non-implemented
method is that other SWT methods doesnt throw the exception.

>> "-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
>> Card\immapp\WebServicesME.jar" -Djava.library.path=\Windows
I'm not sure with your java.library.path option here.
I think it has to be an absolute path or a path that is
relative to your project. ie. if you have a lib folder
inside your Project, put -Djava.library.path=lib
This usually works for me.

>> "-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
>> Card\immapp\WebServicesME.jar"
>> "-Djava.library.path=\Windows\swt-win32-3064.dll"
>> and
>> "-Xbootclasspath/p:\Storage Card\immapp\swt.jar;\Storage
>> Card\immapp\WebServicesME.jar"
>> "-Djava.library.path=\Windows\swt-win32-3064"
These options aren't necessary I think. You only need
to specify the folder where the dlls can be found...

Glenn, you are true, you have the reason.
Then, do you know what another method can i try to invoke for example?
Thanks
