Similar problem here. That code runs on two machines but not on a third. We have WO in the apps bundle.

Runs on machine one using Java 1.5/MacOSX, machine two 1.6/Linux, not on machine three with 1.5/Linux.

I'm trying to get WOPayPal working in WO 5.4, and I've narrowed down to a problem in readResponse(). Below is some sample code I am using to fetch a page from my own web server, and it fails on that as well.

I anybody using WOHTTPConnection.readResponse() ? What am I doing wrong?

I'm running on 10.5.1 client (same happens on server) with WO 5.4 and a 5.4-specific version of WOnder from late December. It does the same with last night's build of the 5.4 WOnder.

// both connectHost and connectPath are set to valid values.

WOHTTPConnection ppEchoConnection = new WOHTTPConnection(connectHost, 80);

NSMutableDictionary headers = new NSMutableDictionary();
headers.setObjectForKey("en", "Accept-Language");
headers.setObjectForKey("iso-8859-1,*,utf-8", "Accept-Charset");
headers.setObjectForKey("image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, */*", "Accept");
headers.setObjectForKey("WebObjects/5.4 [en] (i386; Mac OS X 10.5.1)","User-Agent");


WORequest request = new WORequest("GET", connectPath, "HTTP/1.1", headers, null, null);

request.setContent(connectPath);
ppEchoConnection.setReceiveTimeout(90 * 1000);
boolean success = ppEchoConnection.sendRequest(request);

// everything is working fine to this point. The web server log shows the correct URL is requested and content returned.

if (success) {
stringA = ppEchoConnection.readResponse().contentString(); // NPE below happens here
}
