I have successfully marshaled and unmarshalled my castor generated
classes to an XML file. Now I'm trying to do it over a socket, here is
the base code, I'm sure it's something Java related that I'm doing
wrong, hopefully it's more obvious to you. I'm not sure if the wrappers
that I used are correct, so to send I marshal to the following writer:
Writer x = new OutputStreamWriter(new ByteArrayOutputStream());
and I unmarshall from the following reader:
Reader y = new InputStreamReader(new
ByteArrayInputStream(DatagramPacket byte buffer);
Here's the receiver side:
try {
byte[] buf = new byte[10000];
policyInfo.Policies readPolicies = new policyInfo.Policies();
DatagramSocket ourSocket = new DatagramSocket(4444);
DatagramPacket ourPacket = new DatagramPacket(buf, buf.length);
ourSocket.receive(ourPacket);
ByteArrayInputStream bais = new
ByteArrayInputStream(ourPacket.getData());
Reader byteArray = new InputStreamReader(bais);
System.out.println("byteArray Size is "+ourPacket.getLength());
readPolicies = (Policies)
org.exolab.castor.xml.Unmarshaller.unmarshal(policyInfo.Policies.class,
byteArray);
} catch (Exception e) {
e.printStackTrace();
}
Here's the sender side:
try {
Policies tempPolicies = AddPolicyClass._policyList;
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
Writer byteArray = new OutputStreamWriter(baos);
org.exolab.castor.xml.Marshaller.marshal(AddPolicyClass._policyList,
byteArray);
DatagramPacket ourPacket = new
DatagramPacket(baos.toByteArray(), baos.size(),
InetAddress.getByName("192.168.172.123"), 4444);
DatagramSocket ourSocket = new DatagramSocket();
ourSocket.send(ourPacket);
} catch (Exception e) {
e.printStackTrace();
}
I can run in debug and see the XML, it seems fine. I have actually
marshalled the data to a file, and then I read in the file on the server
side and marshall it to the socket. The file's last character is line
2, column 205 (which is the character 0). Looking at the XML in debug
in the stream, it would have no way of knowing this, so I'm not sure
where that is from, but I get the following errors:
org.exolab.castor.xml.MarshalException: Content is not allowed in
trailing section.{File: [not available]; line: 2; column: 205}

Thanks for any light you may shed on my problem!
