ISSUE:
2010-12-07 14:23:01,623 ERROR [STDERR] (http-0.0.0.0-80-62) org.apache.axis2.AxisFault: Timeout waiting for connection
2010-12-07 14:23:01,624 ERROR [STDERR] (http-0.0.0.0-80-62) at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430)
2010-12-07 14:23:01,624 ERROR [STDERR] (http-0.0.0.0-80-62) at org.apache.axis2.transport.http.HTTPSender.sendViaPost(HTTPSender.java:203)

SOLUTION:
I read the document from the official website. According to the comments, we have these 2 messages:
1. We need stay the axis2 version with 1.5, because axis2 version 1.5.1/1.5.2 has this issue. (Now we are using 1.5, that is right.)
https://issues.apache.org/jira/browse/AXIS2-4752

2. We need to call the method client.cleanupTransport() at the end. (It is right in MW2.1, but wrong in MW2)

IMPROVEMENT:
I will to add these 3 parameters to the AXIS2 client option:
options.setProperty(HTTPConstants.SO_TIMEOUT, 1800000);
options.setProperty(HTTPConstants.CONNECTION_TIMEOUT, 1800000);
options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, Boolean.TRUE);

The REUSE_HTTP_CLIENT option is recommended from the official document to improve the performance. I do a performance test using junitperf to simulate 50 users calling the server side. And I use wireshark to capture the data.
1. If the REUSE_HTTP_CLIENT is true, we will open less connection ports and get the results with good performance.
The snapshot is in right_50.jpg.

2. If the REUSE_HTTP_CLIENT is false or none, we will open many connection ports.
The snapshot is in wrong_50.jpg.

我的测试用例修改为：
public void weatherService(){
RPCServiceClient serviceClient = null;
try{
serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
EndpointReference targetEPR = new EndpointReference("http://192.168.1.149:8080/easyaxis/services/WeatherService");
options.setTimeOutInMilliSeconds(1800000); // 10000 seconds
options.setProperty(HTTPConstants.CHUNKED, Boolean.FALSE);
options.setProperty(HTTPConstants.SO_TIMEOUT, 1800000);
options.setProperty(HTTPConstants.CONNECTION_TIMEOUT, 1800000);
options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, Boolean.TRUE);
// client.getOptions().setProperty(HTTPConstants.AUTO_RELEASE_CONNECTION, Boolean.TRUE);
options.setExceptionToBeThrownOnSOAPFault(true);
options.setTo(targetEPR);
// Setting the weather
QName opSetWeather = new QName("http://services.weather.axis2.sillycat.com", "setWeather");
Weather w = new Weather();
w.setTemperature((float) 39.3);
w.setForecast("Cloudy with showers");
w.setRain(true);
w.setHowMuchRain((float) 4.5);
Object[] opSetWeatherArgs = new Object[] { w };

serviceClient.invokeRobust(opSetWeather, opSetWeatherArgs);

// Getting the weather
QName opGetWeather = new QName("http://services.weather.axis2.sillycat.com", "getWeather");
Object[] opGetWeatherArgs = new Object[] {};
Class[] returnTypes = new Class[] { Weather.class };
Object[] response = serviceClient.invokeBlocking(opGetWeather, opGetWeatherArgs, returnTypes);

Weather result = (Weather) response[0];

if (result == null)
{
System.out.println("Weather didn't initialize!");
return;
}
// Displaying the result
System.out.println("Temperature : " + result.getTemperature());
System.out.println("Forecast : " + result.getForecast());
System.out.println("Rain : " + result.isRain());
System.out.println("How much rain (in inches) : " + result.getHowMuchRain());
}
catch (Exception e)
{
System.out.println("error:" + e);
}
finally
{
try
{
// clear up
serviceClient.cleanupTransport();
}
catch (Exception e)
{
System.out.println("error:" + e);
}
}
}
