RE: How to find a file from a class with Tomcat

[Bongiorno.Christian]

Stick the resource in along with the JAR. Then they will be loaded together and a 
simple call to the file without
a path should discover it

Subject: How to find a file from a class with Tomcat


I have a Servlet S.java which uses a class C.java (not a servlet itself,
could make it one if I had too).
C.java needs to read a config file. The problem is that this class thinks it
is in c:/ or wherever I started the tomcat server from. I can use
this.getClass().getResource(fileName); but that only works with
Properties.load(), not with a FileInputStream.
So at the moment I have all my paths hardcoded into the classes and of
course I don't want that.

My server.xml contains:



And the local web.xml:
   
  hi
  HelloWorldExample
   

  hi
  /hi/*
   


Any tipp would be appreciated.

Why don't you put it in the web.xml
  
directory
[my directory]
  

Then you can grab it from your servlet with a get Context Parameter call.

If you only need a stream (and not FileInputStream) you can use
getResouceAsStream, which will return an InputStream, from which you can
create just about any other stream that you want.

Thanks for all the quick tipps!
Okay, here is what works for me:
InputStream in = this.getClass().getResourceAsStream("1.txt");
int c = 0;
out.println("");
while(( c = in.read()) != -1)
   out.print(((char)c) + "");
out.println("");

* java.io.InputStream and/or java.util.Properties
- InputStream is =
   this.getClass().getClassLoader().getResourceAsStream("xyz.properties");
 - InputStream is =
   this.getClass().getResourceAsStream("testApp.properties");
- InputStream is =

Thread.currentThread().getContextClassLoader().getResourceAsStream("myservle
t.conf");
- InputStream is =
   getServletContext().getResourceAsStream("/WEB-INF/xyz.properties");

-  Properties props = new Properties();
props.load(is);
is.close();

* use java.util.ResourceBundle

* use file-system directly
