Error Reflection

I need help getting the value of a parameter by reflection.

I'm getting the following error:

Error: java.lang.IllegalArgumentException: Can not set java.lang.String field com.jglar.base.dto.BaseAuditDTO.transactionId to java.lang.Class

This is the code I am running:

Main:

public class ObjectUtils {
private ObjectUtils() {
}

public static Map<String, Object> getFieldNamesAndValues(final Object obj,   
boolean publicOnly)
        throws IllegalArgumentException, IllegalAccessException {
    Class<? extends Object> c1 = obj.getClass();
    Map<String, Object> map = new HashMap<String, Object>();
    Map<String, Object> map2 = new HashMap<String, Object>();
    Field[] fields = c1.getDeclaredFields();
    for (Field ls : fields) {
        String name = ls.getName();
        ls.setAccessible(true);
        Object value = ls.get(obj);
        map.put(name, value);
        if (name.equalsIgnoreCase("baseAuditDto")) {
            try {
                Class<? extends Object> c2 = ls.getType();

                Field[] fieldw = c2.getDeclaredFields();
  //                    System.out.println(c2.getField("value3"));
                for (Field dd : fieldw) {
                    String name2 = dd.getName();
                    System.out.println(name2);
                    dd.setAccessible(true);
                    Object value2 = dd.get(c2);
  //                        map2.put(name2, value2);
                }
            } catch (Exception e) {
                System.out.println("Error: " + e);
            }
        }

    }
    System.out.println(map2.get("transactionId"));
    return map;
}

Error:

Error: java.lang.IllegalArgumentException: Can not set java.lang.String field com.jglar.base.dto.BaseAuditDTO.transactionId to java.lang.Class

Please help me.
