Download byte array
Hello,
Iam using a FileResourceStream to download a file. This needs an File, which I create on the fly like this:
tempFile = File.createTempFile("SLA", ".xls");
InputStream data = new ByteArrayInputStream(ConsoleDataHandlerImpl.getInstance().getReportAsByteStream(beginDate,endDate));
Files.writeTo(tempFile, data);
It works fine. But the problem is that it save the tempfile in my tmp folder. Is there a RessourceStream in Wicket which can handle a byte array so that I don't need a tempfile?
Mit freundlichen Grüßen
Christoph Manig

ResourceLink would be simpler.
Christoph should already know that from the previous discussion.
Also see org.apache.wicket.util.resource.AbstractResourceStream. It has few
abstract methods, one of them -
org.apache.wicket.util.resource.IResourceStream#getInputStream.
Just return ByteArrayInputStream.

You can use a org.apache.wicket.request.resource.ByteArrayResource
instead - It's an IResource implementation that takes a byte array. You
can then use the resource in a DownloadLink, for example.
