Yanıt: Re: Adding to response header (filename )?
I dont know the subject, I didnt follow up, but this code is working.
downloadLink = new Link("downloadFile"){
private static final long serialVersionUID = 1L;
public void onClick(){
String tableCode = sourceCode;
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try {
String ContentType = "text";
getResponse().setContentType(ContentType);
((WebResponse)getResponse()).setHeader("Content-Disposition","inline;
filename=\""+fileName+".java\"");
ByteArrayInputStream bais = new ByteArrayInputStream(tableCode.getBytes());
bis = new BufferedInputStream(bais);
bos=new BufferedOutputStream(getResponse().getOutputStream());
byte[] buff=new byte[2048];
int bytesread;
while((bytesread=bis.read(buff,0,buff.length)) != -1) {
bos.write(buff,0,bytesread);
}
bos.flush();
} catch (Exception e) {
e.printStackTrace();
} finally{
try {
bos.close();bos=null;
bis.close();bis=null;
} catch (Exception e) {
}
}
}
};

But you shouldn't call respond yourself. That's for Wicket to do. The
only thing you should do is the the request target on the request
cycle.

Re: Yanıt: Re: Adding to response header (filename)?
That's what I used to use, but it gives the same error. Do you not get
the error in the logs. The error doesn't stop it from working, but I
still would like to do it correctly according to Wicket.

Sorry, this might be easier to understand:
WebResource export = new WebResource() {
@Override
public IResourceStream getResourceStream() {
CharSequence discounts = DataBase.getInstance()

No, There is no error at logs. I have tried to do with wicket but I cant. So I
have done with this way. This link is org.apache.wicket.markup.html.link.Link
and in the org.apache.wicket.markup.html.panel.Panel. And the panel in the
org.apache.wicket.markup.html.WebPage
