How to add a property file to a project/module ?

Hi Farid,

You should mark as a source root directory where target files are located.

Hi Denis,

You mean like this (see attached picture) ?

That's the first or second thing I did but no result...

Yes, I was talking about marking 'resources' directory as a source root.

Could you provide more information on what do you want to achieve then? 'How can I tell IDEA to consider my property files' looks little unclear :(

Denis

Hi Denis,

Sorry for being so little unclear.

I did add the resources directory as source file, but when I want to access said properties, log4j.properties or my own resources.properties, I can't run the following code

public static void main(String argv[]) {
     PropertyConfigurator.configure("resources/log4j.properties");
           properties.load(new FileInputStream("resources/resources.properties"));
      properties.load(this.getClass().getResourceAsStream("resources/resources.properties"));
}

I get a java.io.FileNotFoundException :-(
Is there something else to do (I didn't find it) to ensure that when ran in the IDE, the code finds the resources ?

Thanks again for your time,

Farid

Hi Farid,

Marking 'resource' directory as a source root adds its content to the class path, not the directory itself. That means that target resources can't be accessed via paths like 'resources/log4j.properties'. You should use 'log4j.properties' path instead.

Hi Denis,

It still doesn't work.
I created a simple project and the module still doesn't find the resources.
Here is a snapshot of the structure of the module and my main class.

I tried changing the settings of the ouptut path and so on but again, to no avail.

public class MainClass {

    private static Logger logger = Logger.getLogger(MainClass.class);

    public static void main(String argv[]) {
        try {
            PropertyConfigurator.configure("log4j.properties");

            MainClass app = new MainClass();

            app.initProperties();

            logger.info("End of test module");
        } catch (Exception e) {
            logger.error("Test exception caught: " + e.getMessage());
        }
    }

    private void initProperties() throws Exception {
        Properties properties = new Properties();
        properties.load(this.getClass().getResourceAsStream("resources.properties"));
        // new FileInputStream("resources.properties"));
    }
}

Thanks again,

Farid

Hi Farid,

That is expected behavior because PropertyConfigurator.configure(String) assumes that given argument defines config file path at file system.

However, marking 'resources' directory as a source root makes its content available from classpath. Classpath != file system path.

Solution:

1. (preferred) remove unnecessary call PropertyConfigurator.configure(). Log4j is smart enough to try to pick up config file named log4.properties from classpath;
2. Deliver correct file system path to config file as an argument to PropertyConfigurator.configure(String);

Regards, Denis

Thanks Denis,

But the problem still remains for the resources.properties file.

I can't access the "resources.properties" file.


Farid

Hello,

What do you mean under 'can't access the "resources.properties" file'? What are you trying to do with it?

Denis

Just that I try to load the properties and I have an excpetion saying that I can't...

Farid

Am I right assuming that 'Just that I try to load the properties and I have an excpetion saying that I can't' == trying to execute PropertyConfigurator.configure("resources.properties")?

Denis

No Denis, I'm sorry,

it's just that I'm trying to load some properties of my own in my own resources.properties files which I put in the resources directory.

Whatever the method used to load the properties, I can't do it.

PropertyConfigurator.configure("log4j.properties"); doesn't work
properties.load(this.getClass().getResourceAsStream("resources.properties")); doesn't work.

It seems the resource file can't be found (not in the classpath ?) but the log4j.properties file is.
??

Thanks again for your patience,


Farid

I created minimal standalone module that illustrates accessing resources from classpath. If you start main class you see that resources are successfully loaded.

Please try it and let me know if you have any difficulties with it.

Denis

Awesome !

Thanks Denis.

I know I could use ResourceBundle instead but I'm working on legacy code.

Thanks again...

If you ever come to Paris, France, let me know so we can have a drink ;-)

Ok, thanks :)
