One: Path conversion

The file path format in Windows is D:\eclipse\apache-tomcat-7.0.67\wtpwebapps\ ...

The file path format in Java is d:/eclipse/apache-tomcat-7.0.67/wtpwebapps/...

If you use the path of Windows directly, an exception is thrown when you write with a stream

Using the former in Java will result in an error, so you need to first convert the file path in Windows to a recognized path in Java.

For the following treatment:

String str = "D:\eclipse\apache-tomcat-7.0.67\wtpwebapps\ ...";

String Newurl = str.replaceall ("\\\\", "/");

The value of this newurl is d:/eclipse/apache-tomcat-7.0.67/wtpwebapps/...
