Decoder in a Web Service (java)

[Alejandro]

Hi,

I need a Zxing decoder for my Web Service application.I've tested the
Zxing library in a Desktop application,and i didn' have any
problems,it works right.But when I try to do the same with the WS I
have problems and I can't make a client for send the QR-Code to my
WS.I'm working on Netbeans 6.8 and I've compiled the core and javase
folders and then I add it to the libraries of my WS project.

The propose of my project is to send a photo by the mobile phone of a
QR-Code to the WS,the WS decode the QR-Code and send the answer with
some data else to the client.It's works with a normal photo,I send the
photo and the server receives it.The error if i add the Zxing part
it's the next:

Thanks a lot,

Alejandro.

That's a heck of an error. It is not really from the library though.
The library is unable to create a stack trace for an exception due to
some bizarre internal error: Throwable.getStackTrace() is trying to
create StackTraceElement objects but think it has a no-arg constructor
when it doesn't.

I don't know why -- bad Java versions? corrupted installation? some
weird byte-code surgery that the WS system is doing on exceptions? but
it's nothing to do with us.

[Alejandro]

Thanks for the reply Sean.

I have the java 1.6 version and I reinstalled Netbeans 6.8 the last
week.The error is something weird,because when I comment the Zxing
code,it works right.So the error is only when I uncomment the code.I
show you the code,maybe I'm doing something wrong and if you see the
code can help me.

return s+result;
}



}


ps:Sorry to insist,but I can´t understand the error..

Thanks a lot.

Like I said, it's nothing to do with the library. You'd have to ask
the webservice container provider.
