Using reflection on passed classes

Question

Hello,
I have been trying to write a common function to return the variables and values of a class passed into it. The function uses reflection to iterate through the Fields and returns a string of the variables and values. Is it anything to do with scope, as the same code works when I paste the method into the class I am looking at (See below)?
I have pasted the code fragments below.
Thanks

* Returns XML fragment of name value pairs of member/value
* @param iClass the class under inspection
* @return XML fragment of name value pairs of member/value
public static String inspectMemberVariables(Class iClass)
String oStr = new String();
try
Class c = iClass.getClass();
Field[] f = c.getFields();
System.out.println(f.length);
for (int i=0; i < f.length; i++)
// identify the field
Field fld = c.getField( f.getName());
//get the field name and grab the field value from the class
oStr += f.getName()
+ "=\""
+ fld.get(c)
+ "\" ";
} // for (int i=0; i < f.length; i++)
oStr = "classname=\""
+ c.getName()
+ "\" "
+ oStr;
} //end of try
catch (NoSuchFieldException e)
System.out.println(e);
catch (SecurityException e)
System.out.println(e);
catch (IllegalAccessException e)
System.out.println(e);
} //end of catch
return oStr;
} // end ofinspectMemberVariables
Where the code is called:
public class ReflectionTest extends PPSpposEBCore
public String strg;
public ReflectionTest()
String str2 = new String ();
str2 = ClassProperties.inspectMemberVariables(this.getClass());
System.out.println(str2);
public static void main(String[] args)
String str = new String ();
try
ReflectionTest rt = new ReflectionTest();
// set dummy values to test
rt.mPossessionId = 12;
rt.mBusinessPossRef = "look it works";
rt.mCreatedTs = new Date();
//ClassProperties cp = new ClassProperties();
//str2 = ClassProperties.inspectMemberVariables(rt.getClass());
Class c = rt.getClass() ;
Field[] f = c.getFields();
System.out.println(f.length);
for (int i=0; i < f.length; i++)
// identify the field
Field fld = c.getField( f.getName());
//grab the field name and field value from the class
str += f.getName()
+ "=\""
+ fld.get(rt)
+ "\" ";
} // for (int i=0; i < f.length; i++)
str = "classname=\""
+ c.getName()
+ "\" "
+ str;
System.out.println(str);
} //try
catch (NoSuchFieldException e)
System.out.println(e);
catch (SecurityException e)
System.out.println(e);
catch (IllegalAccessException e)
System.out.println(e);

sorry it doesn't work, interface cannot have method body, i didn't know it. You couldn't access to private and protected datas with an exterior method. You can make a package with classes you want to inspect and a class who inspect. The classes of a package can access to protected datas.
