jsp web应用程序的相对路径

Question

I want to open a file in Java Class in an AWS Java Web project via Eclipse.

I have my file in a folder called "res" in

I tried this

BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream("res\\txtFile.txt"), "UTF-8"));

but not working!

I got

java.io.FileNotFoundException: res\\txtFile.txt (The system cannot find the path specified)

Answer 1

If the file is inside the weapp, you want ServletContext.getResourceAsStream or Class.getResourceAsStream. If it is somewhere else on the filesystem you should probably use an absolute path. A relative path like you used is resolved relative to the directory your appserver started from which might not be what you want.

Answer 2

I solved it !!

used this code to get the absolute path of project anywhere

  String AbsolutePath = new File("").getAbsolutePath();

then add the relative path you need.
