Re: Do a POST with Tapestry and "Link"
It's not really clear what you want to do. With Tapestry you really don't need to fiddling with URLEncoder or connections. Which Tapestry Version are you targeting (3, 4 or 5)? If you use 5 - take a look at the LinkSubmit component (http://tapestry.apache.org/tapestry5.1/tapestry-core/ref/org/apache/tapestry5/corelib/components/LinkSubmit.html). Simple form example with LinkSubmit: # Submit me -- View this message in context: http://tapestry-users.832.n2.nabble.com/Do-a-POST-with-Tapestry-and-Link-tp5717358p5724205.html Sent from the Tapestry Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Do a POST with Tapestry and "Link"
Hi,
I need to do POST in Tapestry for example :
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.*

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.
Re: Do a post with Tapestry and Link
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;
}
