Null Reading config file with getResourceAsStream

Question

I have a class that reads a config file from the project root but it is not finding the file.

My read class is in com.br.xxx.util package

        String filename = "config.properties";
        input = getClass().getResourceAsStream(filename);

This code returns null even though "config.properties" is in my project root. What am I doing wrong?

If I use:

InputStream input = new FileInputStream("C:\\Users\\xxxx\\git\\projectfolder\\project\\config.properties");
configFile.load(input);

It works, but I don't want to use a system path.

`config.properties` must be in your `classpath`. how do you run your project? — Farvardin, Feb 07 '18 at 13:12
The getResourceAsStream() method needs a "class-path". But you are providing only a file name. — Vinit Mehta, Feb 07 '18 at 13:17

System.getProperty("user.dir"); will return current working directory. With the help of current working directory you can get your file. Thanks — Vinit Mehta, Feb 07 '18 at 13:23
probably there is a `classes` in WEB-INF. move file to classes. — Farvardin, Feb 07 '18 at 13:26
@VinitMehta it just returned the same file system path from windows that i wrote on the working code example. — AgamenonD2, Feb 07 '18 at 13:26
@TaherKhorshidi worked after moving to /classes, you can write it as answer. — AgamenonD2, Feb 07 '18 at 13:28
Yes because you said I don't want to use system path, so you need to create a folder in current directory and place that file then you will only be able to get that file. — Vinit Mehta, Feb 07 '18 at 13:29

config.properties must be in your classpath. when you deploy your project on tomcat, by default WEB-IN/classes is in classpath. Simplest solution is to move config.properties to WEB-IN/classes.

Nice, after this i created a folder conf and added it to my classpath. – AgamenonD2 Feb 07 '18 at 13:38
