null inputstream

[ceyesuma]

Hello and thanks in advance for your time.
Why is the InputStream not excepting the String path to a package containing a properties file?

private void writeBtnActionPerformed(java.awt.event.ActionEvent evt) {
        
        String path="/view/resources/projectnames.properties";
        String txtIn=writeTxt.getText();
        PropertyWriter pw = new PropertyWriter();
        try {
            pw.StreamToString(path, txtIn);
        } catch (IOException ex) {
            Logger.getLogger(WriteContentTab.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {
            String txtOut = pw.convertStreamToString();
        } catch (IOException ex) {
            Logger.getLogger(WriteContentTab.class.getName()).log(Level.SEVERE, null, ex);
        }
        txtArea.enableInputMethods(true);
        txtArea.setText(txtOut);

    }
