Dear Wiki user, You have subscribed to a wiki page or wiki category on "Ws Wiki" for change notification.
The following page has been changed by CyrilleLeClerc: http://wiki.apache.org/ws/FrontPage/Axis/AxisCommonsHTTP The comment on the change is: add doc on single instantation of ServiceLocator + others ------------------------------------------------------------------------------ AxisProperties.setProperty( DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, soTimeout); - // you can then call your web service as usual + // Instantiate the ServiceLocator only ONCE !!! + HelloWorldServiceLocator helloWorldServiceLocator = new HelloWorldServiceLocator(); + + ... + + // reuse the same ServiceLocator to instantiate all your bindings !! + HelloWorldBindingStub bindingUserTic = (HelloWorldBindingStub) helloWorldServiceLocator + .gethelloWorldBinding(); }}} + + (!) '''Service``Locator MUST be instantiated only once'''. This single instance must be used to instantiate all the stubs. + This requirement is due to the fact that it is the Service``Locator that in in charge of pooling the http connections : it holds the {{{MultiThreadedHttpConnectionManager}}} via the reference to the {{{CommonsHTTPSender}}}. + + (!) '''Stubs are NOT thread safe''', in most cases, one stub can be instantiated for each call. + In very special cases (very complex WSDLs, ...), the cost of instantiating Stubs will worth pooling them. + + (!) As stated before, '''Stubs are reusable'''. This is the common scenario to maintain a session (see Self:FrontPage/Axis/SessionSupport). It can also be used to gain performances (with a pool) but it should only be efficient in very special cases (see above). + + '''Q: Can I share the same http connections (ie Multi``Threaded``Http``Connection``Manager) between Web Services ?''' + + In Axis 1.3, the {{{MultiThreadedHttpConnectionManager}}} is an internal of the Service``Locator and thus, it is not possible to share the same {{{MultiThreadedHttpConnectionManager}}} between several Service``Locators (i.e. between several web services).
