Hi,
Instead using a servlet you could try the following (you can find the whole
code at wicketstuff pickwick )
This way you will have the session because your are into the
requestCycle....
On your WicketApp....
mount(new URIRequestTargetUrlCodingStrategy("/upload") {
@Override public IRequestTarget decode(RequestParameters
requestParameters) {
try {
return new
UploadRequestTarget(decodeParameters(requestParameters).getString("uri"));
} catch (Exception e) {
throw new WicketRuntimeException(e);
}
}
});
Your own class for uploading images or whatever you want....
public class UploadRequestTarget implements IRequestTarget {
String parameters;
public UploadRequestTarget(String parameters) {
this.parameters=uri;
}
public void detach(RequestCycle requestCycle) {}
public void respond(RequestCycle requestCycle) {
HttpServletRequest
request=((WebRequest)requestCycle.getRequest()).getHttpServletRequest();
HttpServletResponse
response=((WebResponse)requestCycle.getResponse()).getHttpServletResponse();
response.setHeader("Connection","close");
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items=null;
PrintWriter out=null;
try {
out = response.getWriter();
items = upload.parseRequest(request);
for (int i = 0; i < items.size(); i++) {
DiskFileItem item = (DiskFileItem) items.get(i);
// As we are interested not in regular form fields, we
filter only files
if (!item.isFormField()) {
String fileName=COMPLETE IT
item.write(new File(fileName));
out.print("RESP.100");
out.flush();
}
}
} catch (FileUploadException e1) {
out.print("RESP.200");
// flush the stream to speed up applet notification
out.flush();
e1.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
