How to load class files into a project to create an object

With the following code snippet, I am trying to load some class files into my project to create an object. Unfortunately, it seems that something is missing, because there are no classes loaded. What is it?

private static void myClassloader() throws Exception
{
    File file = new File(pathGeneratedClasses);
    try
    {
        @SuppressWarnings("deprecation")
        URL url = file.toURL();
        URL[] urls = new URL[]{url};
        ClassLoader sqlQuery = new URLClassLoader(urls);
        Class myClass = sqlQuery.loadClass("de.cimt.jaxb.JaxCodeGen");
    }
    catch (Exception e)
    {
        System.out.println(e.toString());
    }
}
Solution

  • sqlQuery.loadClass() will be returning the class you requested for, try assigning the returned value to something. If no class is found then ClassNotFoundException will be thrown.
