Hello,
I tried to make the life span of a SOAP service object session wide
without success. I wrote a test service and a test client. If parameter
scope is "application" or "request", it works as I expected. But, when
scope is "session", test program behaves the same way when scope is request.
Would you mind tell me what is wrong. Or am I misunderstanding the
meaning of "session" scope? I appreciate any advice.
version:
Axis-beta1-RC1, Apache Tomcat 4.0.1, JDK 1.3.1_01
Windows NT 4.0 SP6.
Both service and client are running on identical machine.
Detail:
My test service is a Java class LifeSpanTest which has an integer
variable and a getNext method which increment the variable and return
the value.
The client program Test.java repeats making getNext successive call to
the service. When the LifeSpaceTest service is deployed with scope
parameter "application", the client gives following result as I expected.
clear
test start
(1): 1
(2): 2
test end
test start
(1): 3
(2): 4
test end
and, if scope is "request", it gives following result as I expected.
clear
test start
(1): 1
(2): 1
test end
test start
(1): 1
(2): 1
test end
When I set scope "session", I expected,
clear
test start
(1): 1
(2): 2
test end
test start
(1): 1
(2): 2
test end
But, result was.
clear
test start
(1): 1
(2): 1
test end
test start
(1): 1
(2): 1
test end
Source code of the service LifeSpanTest.java, the deploy.wsdd,
and the test client Test1.java is below.
/* Test life span of a SOAP service object. */
public class LifeSpanTest {
private int counter;
public LifeSpanTest() { counter = 0; };
public int clear() { counter = 0; return counter; }
public int getNext() { counter++; return counter; }
}
