struts2 ajax jsonexception

Question

I am getting the below error when making an AJAX call in my struts2 application:

 org.apache.struts2.json.JSONException: org.apache.struts2.json.JSONException:             org.apache.struts2.json.JSONException: java.lang.reflect.InvocationTargetException

The correct Action/method are executed when the ajax call is made.

I made all objects referenced in the Action class implement Serializable.

What can i do to fix this problem? I have been searching on the internet .. but no clues..

Answer 1

The found the problem .. I had BidDecimal objects in my class and JSON serialization is not supported for this type. I converted it to String and double and it iw working now.
