Here\'s a class to do some simple beanish introspection:
import java.io.*;
import java.util.*;
import java.lang.reflect.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Spect {
public static void main(String [] args) {
Spect i = new Spect();
test t = new test();
i.setIt(t, "x", "sam");
System.out.println(t);
}
public static void spect(HttpServletRequest req, Object o) {
try {
Enumeration e = req.getParameterNames();
while ( e.hasMoreElements() ) {
String name = (String) e.nextElement();
String value = req.getParameter(name);
if (value == null || value.equals(""))
continue;
setIt(o, name, value);
}
}
catch(Exception e) {
e.printStackTrace(System.out);
}
}
public static void setIt(Object o, String name, String value) {
Class [] class_array = new Class[1];
Object [] arguments = {value};
try {
class_array[0] = value.getClass();
String function = "set" +
name.toUpperCase().substring(0, 1) +
name.substring(1);
Method m = o.getClass().getDeclaredMethod(function, class_array);
m.invoke(o, arguments);
}
catch(Exception e) { }
}
public static final void log(String s) {
System.out.println(s);
System.out.flush();
}
}
