Re: [Simple-support] problems to deserialize an xml file

Hi,
The problem is class="java.beans.XMLDecoder". An option you can try is this.
Strategy strategy = new TreeStrategy("type", "length")
Persister persister = new Persister(strategy);
This will create a persister that uses a type= attribute to define the types rather than the class= attribute. The persister is reading the class= attribute to determine the type. So because the class="java.beans.XMLDecoder" is not the type you are deserializing you need to ignore it, using type= instead will ignore the class= attributes.
