Message:

Call a dll and read the responding data

Posted by Fredrik on December 18, 2001 at 4:18 AM

I,m trying to connect to an URL that points on a dll, and read the string that the dll returns. I have tryed to use the URL class and the URLConnection but when I try to connect to the URL I get a SocketException [java.net.SocketException: setsockopt() TCP_NODELAY (code 10055)]. If I type the URL with the nessesary parameters in the browser, the dll response and the result (a string) are shown in the browserwindow. How can I do this from a servlet? If anyone could help me out, I would be more than happy.

Here is the code I have tryed:

URL url = new URL("http://www...com/../the.dll?key1=val1&...");

ObjectInputStream in = new ObjectInputStream(url.openStream());

String strResponse = (String)in.readObject();

Thanks in advance.
