Now I am more confused. :-)

Here's the complete class: Basically, it initiates a JNI method
that could take awhile and waits for a user to enter in some Cash,
once the cash has met the expected value (all handled in the C
class) then it returns and I'd like to return the results to the
current browser.
How? HTTP is a pull not a push technology. You can't force the
browser to show something it has not requested.
I'm initiating this in a Thread to avoid using a WOMetaRefresh
page, I just don't like using MetaRefresh...
I don't know of much else that can simulate push technology in http.
And so the user sees a repeating flash animation until all Cash is
inserted and then a response is generated and they are redirected
to a ReviewDetails page.
A flash animation that re-implemented a meta-refresh could, but I
don't see the advantage. How does the Flash know when a response is
generated? It could return the generated response to the browser.

public class PayReader {
public int expectedValue = 1;
public int cashInserted = 0;
public native int matrixCashRead(int expectedValue);
static {
System.loadLibrary("MatrixCash");
}
public WOResponse CashRead(PayReader pr,Application myApp,Session
mySess){
pr.cashInserted = pr.matrixCashRead(pr.expectedValue);
System.out.println("Total Cash Inserted: $" + pr.cashInserted);
System.out.println("----");
String buildURL = "http://"; + myApp.host() + ":" + myApp.port() +
"/cgi-bin/WebObjects/BSSKIOSK.woa/wa/CashRead?wosid=" +
mySess.sessionID() +
"&completed=1&totalcash=" + pr.cashInserted;
WORequest requestFinish = new WORequest("GET",buildURL,"HTTP/
1.1",null,null,null);
WOHTTPConnection connectTo = new WOHTTPConnection(myApp.host
(),myApp.port().intValue());
connectTo.sendRequest(requestFinish);
WOResponse response = connectTo.readResponse();
return response;
}
public Number addCash(String value, Number currentValue){
return new Integer(Integer.parseInt(value) + currentValue.intValue
());
}
}
Here's the thread I'm using to call open this class:
class PaymentThread extends Thread {
Session sess = (Session)session();
public PaymentThread(String type) {
super(type);
}
public void run() {
PayReader pr = new PayReader();
pr.CashRead(pr,(Application)WOApplication.application(),sess);
}
}
Thanks,
Nathan

I am overlooking something it seems or maybe it's just been a
long day but I'm just trying to get the response from the
HTTPConnection request and return that in the current browser
window. Below is the code I've tried:
String buildURL = "http://"; + myApp.host() + ":" + myApp.port() +
"/cgi-bin/WebObjects/BSSKIOSK.woa/wa/CashRead?wosid=" +
mySess.sessionID() +
"&completed=1&totalcash=" + pr.cashInserted;
WORequest requestFinish = new WORequest("POST",buildURL,"HTTP/

WOHTTPConnection connectTo = new WOHTTPConnection(myApp.host
(),myApp.port().intValue());
connectTo.sendRequest(requestFinish);
WOResponse response = connectTo.readResponse();
return response;
You can see that the WOHTTPConnection is Posting to a Direct
Action, I'd like to return the results from that Direct Action to
the browser. This is being done is a private Thread and that's
why I need to do it this way. Can I return the results into the
current browser window ? It seems to of course just return the
WOResponse object which doesn't generate a response in the
current browser window ??
Where is this code? In some action method called during
invokeAction? You would need to hang onto the response and then
in appendToResponse do
response.setContent(responseFromDA.content());
We probably need more information to answer properly.
