通过http代理远程调用webservice SOA

从局域网远程调用外网的webservice服务提供的操作。贴出代码片段。我用的是xfire

/**
     * 获取Client对象实例并设置http代理
     * @return Client
     * @throws Exception 
     */
    public Client getClient() throws Exception {

        String proxyHost = "代理ip";
        String proxyPort = "代理端口";
        System.getProperties().put("proxySet", "true");
        System.getProperties().put("proxyHost", proxyHost);
        System.getProperties().put("proxyPort", proxyPort);

        Client client = new Client(new URL(URL));
        client.setProperty(client.getOutChannel().USERNAME, "代理上的用户名");
        client.setProperty(client.getOutChannel().PASSWORD, "代理上的密码");
//        client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "300");
        client.setProperty(CommonsHttpMessageSender.DISABLE_KEEP_ALIVE, "true");
        client.setProperty(CommonsHttpMessageSender.DISABLE_EXPECT_CONTINUE, "true");
        client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_HOST, "代理ip");
        client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_PORT, "代理端口");
        client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_USER, "代理上的用户名");
        client.setProperty(CommonsHttpMessageSender.HTTP_PROXY_PASS, "代理上的密码");
        return client;
    }
