Re: How to POST data to an external site from an action?
On 5/3/06, Martin Kindler <[EMAIL PROTECTED]> wrote: Thank you all for answering! But I seem not to have stated my problem clearly: I know how I can POST to an uri using Java. My problem is that I want the user to be redirected (or forwarded) to the page my action has posted the data to. The easy way to handle this is: put a button on my page by which the customer selects his preferred payment service. creati an action which prepares the values needed by this payment service. This action forwards to a little jsp-page which contains a form with all the data. When the user submits the form, he is transferred to the payment service with all neccessary information. When a user is transferred to a payment service right from the browser, how does your application know about this? This means two clicks by the user for just selecting a payment service. I do want to make a one-click procedure from this. A solution found by googling automates the second submit by javascript. This is what I now have implemented. The question is: is there a more elegant way? If I use any of the http client approaches (either using java.net or commons httpclient) I get the response somewhere in my action, but it should be in the user's browser. Probably one could say that I need sort of (transparent) proxy like behaviour. Yep, your action behaves as proxy. Also, your application is in the know of what is happening.

Re: How to POST data to an external site from an action?
Here's a quick connect using standard java (not tested):
java.net.HttpURLConnection connection;
java.net.URL url;
try {
// Create new URL and connect
url = new URL("http://www.test.com/test.cgi";);
connection = (HttpURLConnection) url.openConnection();
// Setup HTTP POST parameters
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setUseCaches(false);
String queryString = "myParm1=test&myParam2=test2";
// POST data
OutputStream out = connection.getOutputStream();
out.write(queryString);
out.close();
}
catch (Exception e1) {
System.out.println("Error:" + e1.toString());
}

Hi Martin, Have a look at Commons HTTPClient: http://jakarta.apache.org/commons/httpclient/ This allows you to make various types of HTTP requests, and its easy enough to do from an Action.
