[ http://jira.codehaus.org/browse/XFIRE-747?page=comments#action_79692 ] PJ commented on XFIRE-747: --------------------------
Thx. One more coffee and I figured it out myself ;-) Little inconvenience, but I can live with it... I think that with your explanation this issue can be closed. > Out handlers called twice > ------------------------- > > Key: XFIRE-747 > URL: http://jira.codehaus.org/browse/XFIRE-747 > Project: XFire > Issue Type: Bug > Components: Core > Affects Versions: 1.2.2 > Environment: Linux, JDK 1.5.0_06 > Reporter: PJ > Assigned To: Dan Diephouse > Priority: Critical > > Out handlers are called twice if webservice method calls another webservice > via Client API. > Service interface: > @WebService > public interface ITestService > { > public void a(); > > public void b(); > } > Service implementation: > @WebService (endpointInterface="test.ITestService") > public class TestService implements ITestService > { > public void a() > { > AnnotationServiceFactory factory = new > AnnotationServiceFactory(); > Service service = factory.create(TestService.class); > > try > { > ITestService test = (ITestService) new > XFireProxyFactory().create(service, > "http://localhost:8080/test/services/TestService";); > > test.b(); // while invoking b() out handler > pipeline is called, why??? > } > catch (MalformedURLException e) > { > e.printStackTrace(); > } > } > > public void b() > { > } > } > Example in handler: > public class TransactionBeginHandler extends AbstractHandler > { > public void invoke(MessageContext context) throws Exception > { > Context ctx = new InitialContext(); > UserTransaction ut = (UserTransaction) > ctx.lookup("java:comp/UserTransaction"); > > ut.begin(); > } > } > Example out handler: > public class TransactionCommitHandler extends AbstractHandler > { > public void invoke(MessageContext context) throws Exception > { > InitialContext ctx = new InitialContext(); > UserTransaction ut = (UserTransaction) > ctx.lookup("java:comp/UserTransaction"); > > ut.commit(); > } > } > services.xml: > <beans xmlns="http://xfire.codehaus.org/config/1.0";> > <xfire> > <inHandlers> > <handler handlerClass="test.TransactionBeginHandler" /> > </inHandlers> > <outHandlers> > <handler handlerClass="test.TransactionCommitHandler" /> > </outHandlers> > </xfire> > <service> > <serviceClass>test.TestService</serviceClass> > <serviceFactory>jsr181</serviceFactory> > </service> > </beans> > Test client: > public class Test > { > public static void main(String[] args) throws MalformedURLException > { > AnnotationServiceFactory factory = new > AnnotationServiceFactory(); > Service service = factory.create(TestService.class); > ITestService test = (ITestService) new > XFireProxyFactory().create(service, > "http://localhost:8080/test/services/TestService";); > > test.a(); > } > } > When test client calls method a() below sequence happens: > 1.

TransactionBeginHandler is executed on thread two (T2) > 4. Method b() is executed on T2 > 5. TransactionCommitHandler is executed on T2 > 6. TransactionCommitHandler is executed on T1 > Exception occurs, because second execution of TransactionCommitHandler on T1 > tries to commit already commited transaction. Besides, if after calling b() > some database operations occurs in method a() exception will be thrown > because there is no active transaction. > In my test I've called another webservice on the same server (thus notation > of two threads, T1 handles a() invocation, T2 handles b() invocation), but it > doesn't matter - calling whatever webservice results in invoking handlers > pipeline. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe from this list please visit: http://xircles.codehaus.org/manage_email
