Questions about getting paths for Linux under Request.getrealpath ("/")

Request.getrealpath ("/") gets the root directory of the server in window, with the delimiter at the end,

such as E:\apache-tomcat-6.0.29-bak\apache-tomcat-6.0.29\apache-tomcat-6.0.29\webapps\test\

No delimiters are obtained under Linux, such as:

/home/weblogic/desktop/ptyt/ptytnetpay/webroot

It is therefore necessary to determine the processing:

String root = Request.getrealpath ("/");    if (! Root.endswith (Java.io.File.separator)) {        = root + java.io.File.separator;        }

Finally: the Request.getrealpath () method is deprecated and is recommended for use with Request.getsession (). Getservletcontext (). Getrealpath ("/");
