problem with ResourceLink

[Eyal Golan]

Hi,
We have the following code:

    static public ResourceLink getResourceLink(String id,byte[] data,final
String title,String contentType){
        ResourceLink resourceLink = new ResourceLink(id, new
CustomResource(data,contentType,title)){
            private static final long serialVersionUID = 1L;

            @Override
            protected void onComponentTagBody(MarkupStream markupStream,
ComponentTag openTag) {
                replaceComponentTagBody(markupStream, openTag, title);
            }
        };
        //resourceLink.add(new Label("title",new Model(title)));
        return resourceLink;
    }

and CustomResource is:
public class CustomResource extends Resource{

        String filename = "";
        ByteArrayResource byteArrayResource = null;


        public CustomResource (byte[] data,String contentType,String
filename){
            byteArrayResource = new
ByteArrayResource(contentType,data,filename);
            this.filename = filename;
        }

        public IResourceStream getResourceStream() {
            return byteArrayResource.getResourceStream();
            //return getFile();
            //return getAttachment();
        }

   }

when the user presses a link of a file named: myFile.doc a save dialog is
opened and the file name is ui.doc
I looked into the code and found that in Resource#onResourceRequested
there's the line: cycle.setRequestTarget(new
ResourceStreamRequestTarget(resourceStream));
When I debugged and changed the value of fileName in
ResourceStreamRequestTarget to bla.doc I got the bla.doc in the save dialog.
We use Wicket 1.3.6

How can I call the constructor of ResourceStreamRequestTarget with the file
name?

Another question,
Is there a way to get the content type out of the file without hard coding?
now we have this:
    private String getContentType(String fileName){
        fileName = fileName.toLowerCase();
        String contentType = null;
        if (fileName.endsWith(".doc")) {
            contentType = "application/msword";
        } else if (fileName.endsWith(".html")
                || fileName.endsWith(".txt")
                || fileName.endsWith(".log")
                || fileName.endsWith(".properties"))
        {
            contentType = "text/html";
        } else if (fileName.endsWith(".pdf")) {
            contentType = "application/pdf";
        } else if (fileName.endsWith(".xls")) {
            contentType = "application/vnd.ms-excel";
        } else if (fileName.endsWith(".pot")
                || fileName.endsWith(".pps")
                || fileName.endsWith(".ppt")) {
            contentType = "application/vnd.ms-powerpoint";
        } else if (fileName.endsWith(".zip")) {
            contentType = "application/x-zip-compressed";
        } else if (fileName.endsWith(".jpg")) {
            contentType = "image/jpeg";
        } else if (fileName.endsWith(".png")) {
            contentType = "image/png";
        } else if (fileName.endsWith(".gif")) {
            contentType = "image/gif";
        } else if (fileName.endsWith(".mp3")) {
            contentType = "audio/mpeg";
        } else if (fileName.endsWith(".bmp")) {
            contentType = "image/bmp";
        } else {
//            try {
//                contentType
="text/"+fileName.substring(fileName.lastIndexOf(".")+1);
//            } catch (Exception e) {
//            }
        }
        return contentType;
    }


BTW,
I've noticed that there's DownloadLink. Should we use this?
