Hi
my first solution i wrote isn't working any more. I had to add
beans = {
multipartResolver(is.hax.spring.web.multipart.StreamingMultipartResolver)
}
to /grails-app/conf/spring/resources.xml
Now it works again
@Markus: you can not use byte-arrays with google app engine. You have
to use blobs! See my previous solution.
I put the library in <myApplication>/lib
