Renaud Bruyeron commented on SM-396: ------------------------------------ I see what you are saying...I am not clear at all on the classloader systems inside servicemix, I must admit - diving into the code is the only way to find out, and there is a lot of it :-) I think my problem is related to the deployer system and not to the component lifecycle. In AbstractXBeanDeployer I see that the TCL is set to the classloader that loader the concrete classloader (line 72). The method which is causing my problem is registerService() in the endpoint, which is invoked during the validate(Endpoint) call in Jsr181XBeanDeployer, itself called by AbstractXBeanDeployer during deployment. Therefore at this point, the TCL should be set to the classloader which loaded Jsr181XBeanDeployer. 2 questions: 1) why is this TCL not the correct one? 2) maybe it is the correct one but something else is changing it before reaching validate()? That's how far I got :-) I will try to find some time later today to understand more of my problem. > classloading issue in servicemix-jsr181 - thread context classloader not set > to serviceunit classloader > ------------------------------------------------------------------------------------------------------- > > Key: SM-396 > URL: https://issues.apache.org/activemq/browse/SM-396 > Project: ServiceMix > Type: Bug > Components: servicemix-jsr181 > Versions: incubation > Reporter: Renaud Bruyeron > Attachments: patch.txt > > > the registerService() method in Jsr181Endpoint is running with the servicemix > classloader as the thread context loader, instead of the serviceunit > classloader. > This creates problems when xfire tries to load interface classes referred to > by the @WebService(endpointInterface="...") annotation on the implementation > class.
