Java reflection - how to call setter method?

I'm trying to call set method of some property that I got in my object, my code goes like this:

    String[] fieldsStringName = (((CacheObject)currentObject).getFieldsToString(false)).split(", ");
    String methodName = "";

    for (int i = 0; i < objectInputArr.length; i++) {
        methodName = "set" + fieldsStringName[i];

        Method methodSetProperty = currentObject.getClass().getMethod(methodName);   <<----error goes here
        methodSetProperty.invoke(currentObject, objectInputArr[i]);
    }

The error that i'm getting is:

Exception in thread "main" java.lang.NoSuchMethodException: model.Book.setPagesAmount()
    at java.lang.Class.getMethod(Unknown Source)
    at CahceSystem.createNewObject(CahceSystem.java:84)
    at CahceSystem.main(CahceSystem.java:50)

The requested setter method is well written in the class and also in it's super class (inherited propeties only)

Any suggestions how to solve this issue?
