Call an external url setting method and header
Hi,
I have to call an external url (a rest web service) from onSubmit of a
form.
I found this solution:
|throw new RedirectToUrlException(
"http://www.facebook.com/login.php?api_key="+ _apiKey + "&v=1.0",
HttpServletResponse.SC_MOVED_PERMANENTLY);
but it is just a redirect and I cannot post form data and set the accept header. The web service return different type of data (csv, xml, html, json) depending on the accept header.
How can I handle that?
Best regards
Alberto

Use another IRequestHandler implementation. Like
org.apache.wicket.request.handler.resource.ResourceRequestHandler,
just wrap your response in IResource.

Ok, it's working. I use the following statement:
onSubmit()
...
this.getRequestCycle().scheduleRequestHandlerAfterCurrent(new
TextRequestHandler(contentType, "utf-8", result));
...
)
But is there a way to control the http header (for content location, for
example)? When the result is a csv file the browser uses a weird
filename to write to.

AW: Call an external url setting method and header
Posted by Sven Meier <sv...@meiers.net>.
Hi,
just create you own IRequestHandler.
Instead of interrupting request processing with an exception, just schedule it with RequestCycle#scheduleRequestHandlerAfterCurrent() in your form's submit method.

Yes, I'm using Jersey client for that. But how can I send the output I
read from web service to the browser. SetResponsePage() accept only a
Page class parameter. Sorry if it is a silly question but I'm new to
Wicket. I'm googling since 2 days without success.
