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.
