I'm using yamlbeans to deserialize yaml files into Java objects. This works fine as long as I only have one class. The problem is when I want to nest a field, I am forced to specify the nested class in the yaml description. Single class example: Java: public class MessageField { public String name; public String type; public int length; public String comment; } yaml: name: field1 type: int length: 4 comment: first field --- name: field2 type: string length: 16 comment: second field --- Multiple classes (requires !com.mylib.VariableField in yaml file) Java: public class MessageField { public String name; public String type; public int length; public String comment; public List<VariableField> variableFields; } public class VariableField extends MessageField{ public int id; } yaml: name: field3 type: short length: 2 comment: variableFields: - !com.mylib.VariableField id: 1 name: nestedField 1 type: string le

I am trying to send persisted objects from a java webservice to the ASP.Net client. Both sides have the object-classes, with the same SerialUID's. Classes without (Array)Lists pose no problem, but when I want to send objects including ArrayLists, the expected SUID is incorrect: [java.io.InvalidClassException] = {"the class does not match the class of the persisted object for cl = java.util.ArrayList : __SUID = 8683452581122892189, getSUID(cl) = 9195509126275115639"} Serialization is implemented using binary formatting, not XML because with XML we have circular references between the persisted objects. Using J# at client side, by expecting a java.util.ArrayList instead of an IList or a System.collections.ArrayList doesn't change anything. Any help would be greatly appreciated!
