    WS client reuse http connection

    Chip DeBergh Newbie

      Does anyone know how to set the client (generated by wsconsume.sh) to reuse http connections? Can anyone point me in the right direction?

          I've discovered the http.maxConnections property for JAX-WS. I understand the default is 5 connections, but I am confused as to why my JAX-WS client is opening more that 5 socket connections if there is a max and http.keepAlive is true?
          If anyone could point me in the right direction or let me know if I misunderstood this setting, that would be very appreciated!
          I'm hoping to avoid writing a pool for the jax-ws client to limit the number of socket connections.
          Previously I used axis2. It has an option HTTPConstants.REUSE_HTTP_CLIENT so it would only use one connection over and over. Perhaps JAX-WS has a similar option?

            Figured it out.
            The http.maxConnection settings is not a limit on the total connections but rather the maximum connections to keep open after they were used.
            In my case I consistently have 10 simultaneous requests. So 10 would open, 5 would close, 5 more would open, 5 more would close, and so on. Those that close stay in the TIME_WAIT state for 60 seconds (OS Configuration). This causes TIME_WAIT connections to build up quickly to around ~600. By increasing the maximum idle connections (http.maxConnections) to something larger like 20, open connections are now around 10-13.
            Axis2 only opens one connection per port instance (no pool) whereas JAX-WS pools multiple connections as they are needed.
