i have two beans: 1: class Zoo { private String firstName = "Zoo1";
public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } } 2: class Pojo { private String firstName = "Pojo1"; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } } and engine class is: import org.apache.commons.beanutils.BeanUtils; public class ZipcodeLookup { public static void main(String[] args){ Pojo p = new Pojo(); Zoo z = new Zoo(); try { BeanUtils.copyProperties(z, p); String ss = new String("ssss"); BeanUtils.setProperty(z, "firstName", ss); } catch (Exception e) { System.out.println("ex... "+e.toString()); } System.out.println("Zip: "+z.getFirstName()); System.out.println("Pojo: "+p.getFirstName()); } } when it executes this line: BeanUtils.copyProperties(z, p); it does noting, its not copying the properties to z, and when it executes this line String ss = new String("ssss"); BeanUtils.setProperty(z, "firstName", ss); it dies by saying java.lang.reflect.InvocationTargetException: Cannot set firstName see log: [20060714 17:46:23] DEBUG BeanUtils : BeanUtils.copyProperties([EMAIL PROTECTED], [EMAIL PROTECTED]) [20060714 17:46:23] DEBUG BeanUtils : setProperty([EMAIL PROTECTED], firstName, ssss) [20060714 17:46:23] DEBUG ConvertUtils : Convert string 'ssss' to class 'java.lang.String' [20060714 17:46:23] DEBUG ConvertUtils : Using converter [EMAIL PROTECTED] ex... java.lang.reflect.InvocationTargetException: Cannot set firstName Zip: Zoo1 Pojo: Pojo1 what is the problem, i try injecting data using reflection that works, why its not?
