How to send serialize/byteArrayOutput stream from wicket page
Hello,
How can i send a serialize object using byteArrayOutput stream in wicket
page. here is my code:
public class BridgeIndex extends WebPage {
public BridgeIndex()
{
final HttpServletResponse response =
getWebRequestCycle().getWebResponse().getHttpServletResponse();
ObjectOutputStream out = null;
final ByteArrayOutputStream byteObj = new ByteArrayOutputStream();
final BridgeObject bObj = new BridgeObject();
bObj.setPassword("123456");
bObj.setUsername("test");
try
{
out = new ObjectOutputStream(byteObj);
log.info("Serializing the object...");
// serialize the object
out.writeObject(bObj);
response.setHeader("Cache-Control", "no-store");
response.setHeader("Pragma", "no-cache");
response.setContentType("application/octet-stream");
final ServletOutputStream outstream = response.getOutputStream();
outstream.write(byteObj.toByteArray());
outstream.flush();
outstream.close();
}
catch (MalformedURLException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
...i get this error....

Posted by Johan Compagner <jc...@gmail.com>.
you cant do it like that
look at ResourceStreamRequestTarget
what you want is a combination of that and AbstractRestartResponseException
so you must set the RequestTarget in the RequestCycle and then throw an
AbstractRestartResponseException
(just like RestartResponseException works)

Re: How to send serialize/byteArrayOutput stream from wicket page
Posted by Jonas <ba...@gmail.com>.
I think the wicket way to do this is using a
org.apache.wicket.markup.html.WebResource
(or any of its subclasses) instead of a WebPage
