Java EE (Java Enterprise Edition) General Discussion

Hi,

I am using castor to unmarshal an xml into a java object.
This object has member variables as collections (List).

Even though in the mapping file I used collections attribute of <field> tag and has set it to arraylist, it is still throwing this exception.

After doing a bit of research on this,I found that since UnmarshalHandler uses reflection to create object from xml, it is trying to invoke java.util.List.newInstance() which is causing this problem.

The class which I am trying to unmarshal is an already existing class and I cannot change the type of the member variables to ArrayList from List.

How can it be resolved?
