But how also can't jump, I checked a few times configuration file, really no problem, this started depressed,
Started Google, but the answer is different on the web, it is to see my dazzling, finally changed a browser good,
That this must be the reason for IE, open IE's options to see if there is anything special set, exactly Google time
An article said it is possible with the IE option in the friendly HTTP error hint about, finally solved the problem, hehe.
The front tick of the friendly HTTP error prompt will be displayed in advanced ,Internet Options , ie tools , OK.
Java is good, worth learning.
