Hi Ramkumar, The article shows that we need to create an adapter to the class that does not have a no-arg default constructor, ie, create a class that extends * XmlAdapter<>* and implement the inherited methods. Moreover, we need to annotate the class that was adapted with *...@xmljavatypeadapter* annotation.
However, the problem is that although the *Exception* an *Throwable* classes have no-arg default constructors, the *StackTraceElement* doesn't. So, I would need to create an adpater to *StackTracElement* and annotate it with * @XmlJavaTypeAdpater*, what is not possible. Is it right, or I am missing something?
