public class SupplierCalculatorApplet extends JApplet{
...
public void init(){
    loadProperties();
    ...
}   

...

private void loadProperties() {
    language = "en-us";//getParameter("Language");
    prop = new Properties();
            try {
                URL urlToProps = this.getClass().getResource("config/" + language + ".properties");
                prop.load(urlToProps.openStream());//Exception Caught Here
            } catch (IOException e) {
            }   
}

例外情况见上表。无论是语言是有效的财产档案,我还是同一条线上相同的例外。

Answer 1

改为:

prop.load(this.getClass().getResourceAsStream("/config/" + language + ".properties"));

Answer 2

您给我们许多工作要做,但我的猜测是:urlToProps> 。因此,urlToProps. openStream(> part将扔下一台NPE。
