Acces file from other project where the source is

Question

I have a project(project source) with .txt file which I want to access from other project (project caller). caller has dependecy over source. So caller should see source as .jar. Well, the question, I have to access to this .jar to obtenin the .txt file but I cannot. I have tried thinks like: getClass().getResourceAsStream("classpath:/cc.txt"); with InsputStream and getClass().getResource("cc.txt"); with URL object but I always got a null. All forums I ve read speaks about this way to access. How do I suposse to access to a .jar file to get the .txt file? thanks all!!

Extract the Contents of ZIP/JAR Files Programmatically. Suppose jarFile is the jar/zip file to be extracted. destDir is the path where it will be extracted:

java.util.jar.JarFile jar = new java.util.jar.JarFile(jarFile);
java.util.Enumeration enum = jar.entries();
while (enum.hasMoreElements()) 
{
    java.util.jar.JarEntry file = (java.util.jar.JarEntry) enum.nextElement();
    java.io.File f = new java.io.File(destDir + java.io.File.separator + file.getName());
    if (file.isDirectory())  // if its a directory, create it
    {
        f.mkdir();
        continue;
    }
    java.io.InputStream is = jar.getInputStream(file); // get the input stream
    java.io.FileOutputStream fos = new java.io.FileOutputStream(f);
    while (is.available() > 0)  // write contents of 'is' to 'fos'
    {  
       fos.write(is.read());
    }
    fos.close();
    is.close();
}
