I'll give you a "pseudo-code", this probably won't compile but will give you a start:

 

...

Thread ws1 = new Thread( new Runnable() { public run() { // call your code that invokes WS1 } }

 

Thread ws2 = new Thread( new Runnable() { public run() { // call your code that invokes WS2 } }

 

// this will start the threads and cann the "run" mehtod

ws1.start();

ws2.start();

 

// This will wait until the WS-threads have finished, ie run until the end of the "run" method

ws1.join();

ws2.join();

 

// pickup the data that was deposited by the threads

 

Object ws1Result = mySyncrnoizedMap.get("ws1");

Object ws2Result = mySynchronizedMap.get("ws2");

 

...

Hi Jesper,

 

i didn't know that it could be possible to wait diferents threads. This is the solution i need���

 

Do you know any sample code or pattern applied to this???

 

Thank you very much.

 

Enrique.

That sounds a bit over ambitious unless you want to do something with these response separatly later on. If they are both a part of a single transaction a much simpler approach would be to:

- spawn off 2 thread

- have the spawning thread wait (join) on the two threads running to completion

- have the 2 threads deposit the result in a synchronized collection of some kind

- the waiting thread pick up the result after the two threads have terminated and they continue processing.

Yes i could do it, but where i store the response of differentes threads of differnets calls.

I'm thinking that i should have and ID of any group of calls, and store the response in a database, that i wil consult some time later, 10 seconds, or something like that.

Regards, Enrique.

I haven't done it personally, but I would think that you could bust out a couple of threads and do it?

Hi all,

two days browsing internet and i can't find any clue to do it, many parallel
calls to diferente web service.

I don't know if this is imposible, but I think that it should be a normal behavior.
did anyboy do something similar??

Any help will be very apreciated.

Regards, Enrique.
