How to get handle to a resource within a JSF class?
classpath, jsf, properties, resources
Solution
It's thus in the classpath. You can just use `ClassLoader#getResourceAsStream()` to get an `InputStream` out of it. Assuming that `src` is the classpath root and that `main/resources` is the package:
InputStream input = Thread.currentThread().getContextClassLoader().getResourceAsStream("main/resources/foo.properties");
Properties properties = new Properties();
properties.load(input);
// ...
Alternatively, if it's supposed to be specific to the webapp and thus isn't supposed to be overrideable by a file on the same path elsewhere in the classpath which has a higher classloading precedence (e.g. in appserver's lib or the JRE's lib), then use `ExternalContext#getResourceAsStream()` instead.
InputStream input = FacesContext.getCurrentInstance().getExternalContext().getResourceAsStream("main/resources/foo.properties");
Properties properties = new Properties();
properties.load(input);
// ...
As to the `#{resource}` syntax, this is indeed specifically for CSS/JS/image resources placed in `/resources` folder of public web content. See also How to reference CSS / JS / image resource in Facelets template?
Problem
I've put a properties file within `src/main/resources` in my JSF project. How do I get a handle to it? I understand that EL doesn't work within a backing bean. Note: The file is in `src/main/resources` - NOT `src/main/webapps/resources`, so the following doesn't work: ``` FacesContext context = FacesContext.getCurrentInstance(); File value = context.getApplication().evaluateExpressionGet(context, "#{resource['resources:email.properties']}", File.class); ```
