"java.SocketException:Connection reset" after which follows "java.lang.NullPointerException"
I have two questions :
1.Weblogic 11g log often generates exceptions like this: "<BEA-101020>Servlet failed with Exception: java.SocketException: Connection reset." after which comes "<BEA-000802>java.lang.NullPointerException at jsp_servlet.__error._exceptionMsgForInner(__error.java:57)".
Please tell me what reason cause this problem?
2."<BEA-000449>Closing socket as no data read from it on *.*.*.*:*,* during the configured idle timeout of 5 secs", also, I want to know what problem could cause this issue. I googled it and found someone just made a filter to keep this waring quiet. But I want to know excactly how this happened?
