我的应用程序需要连接到Web服务。客户端给出的WSDL文件使用轴2-1.5.2中的wsdl2java实用程序转换为java。在第一次连接到Web服务期间发生此问题。它给了我

我尝试在网上搜索答案，虽然有一个地方提到它可能是阻止的webservice端的防火墙，但我找不到有效的解决方案。任何帮助都感激不尽。

运行：

  • Apache Tomcat 6.0
  • Axis2 1.5.2

1 个答案:

答案 0 :(得分：0)

针对Web容器的第一个请求（例如Tomcat）通常首次加载servlet。诸如AxisServlet，CXFServlet等框架servlet通常在其启动生命周期阶段执行大量操作。例如，Axis加载其内部服务注册表，连接并公开服务。 CXF做同样的事情，查看Spring配置文件，依此类推。

因此，首先快速检查是否应该将标记添加到web.xml。

这是在servlet级别 - 其他弹性资源也可以延迟第一个请求（例如连接池 - 实际上是第一次填充的任何池）。

当然，这可能不是唯一的原因 - 堆栈跟踪显示SSL连接。根据Web服务的位置，可能是通过XML安全网关与安全服务（例如OCSP证书验证服务）进行交互？ “固定套接字”表明JRockit JVM足够智能，可以在可能的情况下创建长期存在的SSL连接，因此可能需要花费很长时间才能进行证书交换过程 - 可能是增加时间窗口的平台配置？

服务器和客户端之间是否还有其他问题？ Web容器的Web连接器（例如Apache + mod_jk），app服务器负载均衡器等？可以剥洋葱并检查它们。

您的堆栈跟踪还建议您有一个背对背的用户代理（例如，服务器接受请求，然后在某处发出出站请求）。如果您向本地实例发出出站请求（例如，客户端向localhost发送请求：8080，8080上的webapp将请求发送到localhost：8080 /另一个Web应用程序），您可能会资源匮乏您的容器，可能是一个症状最终的死锁（即循环请求正在等待线程池释放以提供请求，但所有人都在等待）。这种风格条件在任何Web服务器/应用服务器组合中都适用，您可以根据自己的设置转身并发出网络请求。
