How to get the root path of my project?

I have JSP projects that run in Tomcat developed in Eclipse.

I want to have some files which I store inside the project.

Here is the project structure that I have:

.settings
build
data
ImportedClasses
src
WebContent
.classpath
.project

I want to access the data folder from my code in JSP file which located in WebContent.

Tried some code below:

File userDataDirFile = new File ( "data" );
String path = userDataDirFile.getAbsolutePath();

prints

C:\Program Files\eclipse\data\users

Then

this.getClass().getClassLoader().getResource("").getPath()

prints

C:/Workspaces/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/survey/WEB-INF/classes/

Another one:

System.getProperty("user.dir")

prints

C:\Program Files\eclipse

There is no code that I tried (I think the 2nd solution supposed to work, but it doesn't) can locate me to root folder of my project. Anyone can advise?

String caminhoProjeto = Thread.currentThread().getContextClassLoader().getResource("").getPath();

This is like "src" path, but is the "classes" path of binaries files context after deployment and runtime.

My class for example of the necessarie use of this way "root dir of project":

PropertiesReader.java:

public class PropertiesReader {

    public static String projectPath = Thread.currentThread().getContextClassLoader().getResource("").getPath();
    public static String propertiesPath = "/META-INF/";

    public static Properties loadProperties(String propertiesFileName) throws IOException {
        Properties p = new Properties();
        p.load(new FileInputStream(projectPath + propertiesPath + propertiesFileName));
        return p;
    }

    public static String getText(String propertiesFileName, String propertie) {

        try {
            return loadProperties(propertiesFileName).getProperty(propertie);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return propertie;
    }
}

PersonRegistration.java:

@ManagedBean
public class PersonRegistration {
    private Integer majority = Integer.parseInt(PropertiesLeitor.getText("Brasil.properties", "pessoa.maioridade"));
}

Brasil.properties (within src / META-INF):

pessoa.maioridade = 18

Edit : File that are not in WebContent will not be deployed with your war. you have to put files used in you code inside the WebContent and try with ServletContext which point to the root folder of the your web application : if your file is at the same folder as WEB-INF then :

ServletContext context = getContext();
String fullPath = context.getRealPath("/data");

by the way if you don't want to give direct access to data file it's recommanded to put it in WEB-INF so that no one can have access to them directly.
