I believe the problem here may be that class Zoo and class Pojo are not
declared public.
When BeanUtils tries to find an setter that is accessible to it, it
needs to check for a public method as well as a public class.

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:

Pojo: Pojo1
what is the problem, i try injecting data using reflection that works, why its
not?
