java.lang.UnsatisfiedLinkError

[jlc488]

Hi,

I am a newbie here. Please understand if my question is stupid.

Ok, I am thingking about implementing simple test code like GWT + S3.

I use GWT 1.6.4 and to work with S3, I use gwt-s3 library version
0.9.2.

And somehow I am getting exception which I found hard to debug.

Can anyone please share opinions or guide some ideas?

Thank you advance.

I´m not familiar with the S3 API, but every time I´ve seen
UnsatisfiedLinkError
the problem has been

A) A client side only function was called from the server side
B) A server side only function was called from the client side

So make sure there are no S3-functions that can not actually be used
on the server side
