Just a few comments Petr is describing two problems I think: the blocking nature of Call.invoke, and the lack of a cancellation method for halting a Call.invoke.
As to the blocking problem, there is no documentation on it, but in the "org.apache.axis.client.async" package, there is an AsyncCall(Call call) that appears to return immediately from an invoke call. One option for you in immediate future is to setup an async call, and when the invoke returns (through a callback by the if I'm guessing correctly on IAsyncCallback), you can simply not process the result if someone clicked on your cancel button. A user will need never know that a request did come it which you ignored. As to the lack of cancellation, I would guess that Axis is probably constructed using blocking I/O calls which could be moved to loops that check if an InputStream.available() > 0 instead of depending on the blocking of a read(byte [] bytes). In such loops, a check could be made to see if a cancellation flag has been set. I wish I had time to take a look at the source. I'm sure what I'm describing isn't trivial, but none-the-less, in time Axis will probably have such functionality at which point you can update your app accordingly. BTW, I have no actual knowledge of the development schedule of Axis. My conjecture that cancellation will be implemented sometime soon is based on my belief that your issue isn't unique, and from my view (from a far distance from the source code), wouldn't be that challenging to implement. ----- Jason Judt - Software Engineer Architecture Technology Corporation (952) 829 - 5864 x137 [EMAIL PROTECTED] -----Original Message----- From: James Clinton [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 25, 2005 10:38 AM To: [EMAIL PROTECTED] Subject: RE: abort call.invoke (SOAP client call) You can use Thread.join(long m) to solve your problem like this: ======= public class Tester { InvokerThread invoker; static boolean gotResponse = false; public Tester() throws Exception { invoker = new InvokerThread(); invoker.start(); invoker.join(12000); if(gotResponse) { System.out.println("got response in time"); } else { System.out.println("send back customer response"); } } public static void main(String[] args) throws Exception { Tester t = new Tester(); System.exit(0); } } class InvokerThread extends Thread { public void run() { Thread thisThread = Thread.currentThread(); while (true) { try { thisThread.sleep(10000); Tester.gotResponse = true; } catch (InterruptedException e){ } } } } ---------------------------------------------------------------------------- ------------------ Did you know?
