[jbossws-issues] [JBoss JIRA] Reopened: (JBWS-1857) JAXBContext created for every invokation of service.getPort()

JAXBContext created for every invokation of service.getPort() ------------------------------------------------------------- Key: JBWS-1857 URL: http://jira.jboss.com/jira/browse/JBWS-1857 Project: JBoss Web Services Issue Type: Bug Security Level: Public(Everyone can see) Components: jbossws-native Affects Versions: jbossws-1.2.1, jbossws-2.0.1 Reporter: Johann Gyger Assigned To: Thomas Diesler Attachments: jbossws-src-1.2.1.GA-jaxb-context.patch, jprobe_service_get_port.txt service.getPort() may become an expensive operation (i.e., several seconds) when using a non-trivial WSDL with complex types. We have been able to track down our performance problems to an incorrect usage of JAXB-RI in JBOSS-JAXWS. According to https://wsit.dev.java.net/servlets/ReadMsg?list=dev&msgNo=66 creating new instances of JAXBContext is an expensive operation. In our WSDL we counted 28 instance creations of JAXBContext. Most of them are created through the following call hierarchy: JAXBContext.newInstance(Class[], Map<String,?>) line: 570 JAXBContext.newInstance(Class...) line: 522 JAXBAccessor$1.create(Class) line: 67 JAXBAccessor$1.create(ParameterMetaData) line: 54 ParameterMetaData.eagerInitialize() line: 470 OperationMetaData.eagerInitialize(List<Method>) line: 469 ClientEndpointMetaData(EndpointMetaData).eagerInitializeOperations() line: 516 ClientEndpointMetaData(EndpointMetaData).initializeInternal() line: 502 ClientEndpointMetaData(EndpointMetaData).eagerInitialize() line: 490 JAXWSClientMetaDataBuilder.rebuildEndpointMetaData(EndpointMetaData, Class<?>) line: 292 ServiceDelegateImpl.getPortInternal(EndpointMetaData, Class<T>) line: 274 ServiceDelegateImpl.getPort(QName, Class<T>) line: 200 A JProbe analysis (see attached file) revealed that actually most of the time (96.4%) of service.getPort() is spent in JAXBContext.newInstance(). Please see attached JProbe report. Compared to JAX-WS RI (Metro) the performance of service.getPort() is extremely bad.
