I subclassed DynamicWebRessource, but I still have the problem that I do not
know how to add the RessourceState to my WebResponse for my download link.
I found the class ResourceReference but no I did not find out how to use it.
Do I have to use the ResourceReferece Class or is there another way to get my
download working?
Perhaps you could give me a short example
Thanks
Robert

Betreff: Re: [Wicket-user] Writing byte[] to a WebResponse
The reason you're getting errors in MS Word is that you're converting a byte
array into a String using ByteArrayOutputStream's toString() method. A Java
String and a byte array are not always the same thing due to unicode.
Subclass wicket.markup.html.DynamicWebResource so that it returns the correct
instance of ResourceState (also your own implementation). Among other things,
ResourceState is supposed to provide a byte array that is the content of the
download. This would be the byte array from your database.

Hello
I store a lot of MS Word and Excel files as a byte[] into my database.
I want to add a feature to download these files from the database
again, but I did not find a way to do this in Wicket, without writing the
byte[] to a File again.
Is there a way to write a byte[] to a WebResponse? I tried the same
Code, which is available at the Export Example from Wicket
I got my byte[] from the database and then wrote it to a
ByteArrayOutputStream.Then I used the toString() method. But if I download the
file then I get a lot of conversion errors from MS Word, so I would like to
write the byte[] directly.
So I tried this method: response.getOutputStream().write(file);
But using this I get this error:
java.lang.UnsupportedOperationException: Cannot get output stream on
BufferedResponse
Thanks for any help
