Hi,
I'm trying to pass an object over RPC but the call is failing with a
"com.google.gwt.user.client.rpc.SerializationException" exception.
Complete stack trace is below. How do I figure out what field is
causing the problem? The class and its member fields in question
are ...
public class XmlNode implements Serializable {
private Node dataRoot;
private List<XmlNode> parents = new ArrayList<XmlNode>();
private List<XmlNode> children = new ArrayList<XmlNode>();
...
public class Node implements Serializable {
private long id;
private short type;
private String name;
private String value;
private List<Node> children;
private Node parent;
private Map<String, Attribute> attributes;
...
public class Attribute implements Serializable {
private String name;
private Object value;
private Node node;
There are getters and setters for everything. How do I get GWT to
tell me more about why Serialization is failing? - Dave
ps - The error stack trace is
com.google.gwt.user.client.rpc.SerializationException: Type
'com.cme.clearing.common.xml.XmlNode' was not included in the set of
types which can be serialized by this SerializationPolicy or its Class
object could not be loaded. For security purposes, this type will not
be serialized.: instance = XmlNode
