> Bug with concurrent soap requests and aegis
> -------------------------------------------
>
> Key: XFIRE-773
> URL: http://jira.codehaus.org/browse/XFIRE-773
> Project: XFire
> Issue Type: Bug
> Components: Aegis Module
> Affects Versions: 1.2.2
> Environment: win xp, jdk-1.5.0_06, apache-tomcat-5.5.17,
> spring-1.2.6, httpclient-3.0.1
> Reporter: Jose Dillet
> Assigned To: Guillaume Nodet
> Attachments: BeanTypeInfo.java, testWS.war, WS Test.jmx
>
>
> I'm getting some problems when I launch some concurrent requests to a web
> service made using xfire and spring.
> I have a simple service (MyService) with a method (testService) that returns
> an object (MyObject).
> I test it launching some concurrent requests using JMeter (jmeter -n -t "WS
> Test.jmx").
> With this test, sometime I get the following exception:
> 2006-11-22 17:53:16,078 ERROR
> [org.codehaus.xfire.handler.DefaultFaultHandler] Fault occurred!

> and sometimes it ends without any exception. Also, when I get an exception,
> and I try to access to wsdl file, sometimes I get another exception, or
> sometimes the definition of the object MyObject returned is wrong, because
> every field is repeated many times.
> I guess that problem is related to aegis configuration, because if I delete
> file MyObject.aegis.xml, then I never get these errors. Unfortunately, not
> all executions end with an exception, but launching it several times leads to
> finally get some of these exceptions.
> In testService I have added a sleep, to slow the execution of the method. In
> my real project, there is no sleep, but my service method is heavier, so I
> put the sleep to emulate the behaviour of my real service.
> I attach a war with a complete test application, a a jmx file to test the
> application with JMeter (launching 30 concurrent threads)
> Hope you can reproduce the bug.
