Do a post with Tapestry and Link
Hi,
I need to do POST in Tapestry for example :
<form method=*"POST"* Action=*"*MyURL*"* name=*"name"*>
<input type=*HIDDEN* name=*"FirstParam"* id=*"IdFirstParam"*value=
*"*Value*FrstParam"*/>
<input type=*HIDDEN* name=*"SndParam"* id=*"IdSndParam"* value=*
"*Value*SndParam"*/>
</form>
When I try :
String data = URLEncoder.encode("*FirstParam*", "UTF-8") + "=" +
URLEncoder.encode("*FirstParam*", "UTF-8");
data += "&" + URLEncoder.encode("*SndParam*", "UTF-8") +
"=" + URLEncoder.encode("*SndParam"*, "UTF-8");
// Send data
URL url = new URL(*MyURL*);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
But Tapestry tell me that I must use :
java.net.URL, org.apache.tapestry5.Link, org.apache.tapestry5.
StreamResponse
Any one know how to do ?
Thanks in advance
*Khalid.*

Tapestry handles request, doesn't makes them. Use HttpClient for that.

My interpretation was correct. Tapestry (and any other web framwork) don't
do POST requests, they handle them. You'll need to use HttpClient to do
that or rethink the logic you're trying to implement.

Thank you Joost and Thiago,
May be may question wasn't clear. So what I need that a method return an
object that make a post with the previous params.
I hope that is more clear now.
Cheers,
Khalid.

If I read this correctly you are using an external java program to
post to a tapestry page. Correct?
The error you are refering to is usually associated with the required
return type from an event method which you have not shown in your post.
Can you post the page code handeling the POST request? For refference,
below you will find the onActivate code of a page I use to handle
external XML POST requests.
Cheers,
Joost
---------- a POST handling page ----------
@OnEvent(value = EventConstants.ACTIVATE)
private Object activate() throws Exception {
HttpServletRequest httpServletRequest =
requestGlobals.getHTTPServletRequest();
ServletInputStream inputStream =
httpServletRequest.getInputStream();
SAXBuilder builder = new SAXBuilder();
Document xmlRequest = builder.build(inputStream);
String response = ... build the response xml Document ....
final ByteArrayInputStream output = new
ByteArrayInputStream(response.getBytes());
final StreamResponse streamResponse = new StreamResponse() {
public String getContentType() {
return "text/xml";
}
public InputStream getStream() throws IOException {
return output;
}
public void prepareResponse(Response response) {
}
};
return streamResponse;
}
