Websphere & Spring: Connection timed out while reading request
Hello experts:
I am using websphere 5.1 and Spring 2.0.3 to develop a simple login page. However I got the following error message:
Error 500: HTTP/1.1 408 Connection timed out while reading request Server: WebSphere Application Server/5.1 Content-Type: text/html Content-Length: 142 Connection: close
408 Connection timed out while reading request
This error message only occurres at the first one or two entry after the server restarted. And the following retries will be no problem. I have also tried to put the same codes on Tomcat, it doesn't have such problem.
The exception thrown by the server is:
