是通过Axis2 1.5.4线程安全的WSDL2JAVA(使用XMLBeans绑定选项)生成的存根吗？

实际上我已经为一个Web服务创建了一个Stub,我通过多个线程调用它.我已经配置了自己的MultiThreadedHttpConnectionmanager设置,HTTPConstants.REUSE_HTTP_CLIENT但我看到一些NullPointerExceptions stub._getServiceClient().cleanupTransport,我在每次调用后调用.

有时线程也会挂起.

同时我注意到在Web Service操作方法中生成的Stub中,在finally块中已经调用了cleanup().stub._getServiceClient().cleanupTransport我以后不应该打电话给自己吗？

我的代码:

        httpConnMgr = new MultiThreadedHttpConnectionManager();
        HttpConnectionManagerParams params = httpConnMgr.getParams();
        if (params == null) {
            params = new HttpConnectionManagerParams();

        }
        params.setDefaultMaxConnectionsPerHost(numberOfThreads);
        httpConnMgr.setParams(params);
        HttpClient httpClient = new HttpClient(httpConnMgr);

        service = new Service1Stub(this.endPointAddress);
        service._getServiceClient().getOptions()
                .setTimeOutInMilliSeconds(this.timeOut);
        service._getServiceClient().getOptions()
                .setProperty(HTTPConstants.REUSE_HTTP_CLIENT, Boolean.TRUE);
        service._getServiceClient().getOptions()
        .setProperty(HTTPConstants.AUTO_RELEASE_CONNECTION, Boolean.FALSE);
        service._getServiceClient()
                .getOptions()
                .setProperty(HTTPConstants.SO_TIMEOUT, (int) (this.timeOut));
        service._getServiceClient()
                .getOptions()
                .setProperty(HTTPConstants.CONNECTION_TIMEOUT,
                        (int) (this.timeOut));
        service._getServiceClient().getServiceContext().getConfigurationContext()
                .setProperty(HTTPConstants.CACHED_HTTP_CLIENT, httpClient);

同时在生成的存根中,我注意到已经调用了cleanUp:

   finally {
            _messageContext.getTransportOut().getSender().cleanup(_messageContext);
        }

任何建议都会有很大帮助.谢谢.
