There is such a paragraph in the struts file, but if you come to read something in this file,
"- // Apache Software Foundation // DTD Struts Configuration 1.1 // En" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
If you read this file when you initialize the servrlet, if there is no connection,
If you can't read this file, he will cause NESTED issues. But if you put
Http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd This file is downloaded to the local, reuse, everything is normal.
Oh, I don't know if it is bug, or? And if you remove it, you will be wrong, and Struts cannot be used.
