Re: [castor-user] a sequence of objects can be serialized but not deserialized

[Martin Gainty]

Jeremy-
Coming up empty for documentation and or references using ObjectStream 
*outside of legacy applet scenarios*
Could you be more specific on where to find doc and perhaps an example?

Thanks,
Martin-

Not sure whether this is the reason for Mark, but I'm doing something
similar and had problems with firewalls when using sockets, whereas an
ObjectStream can easily be returned from a servlet.

Why not connect thru TCP socket and parse the contents?
Yes/No?

Hi,
Castor appears to require a root element to unmarshall objects.  How 
would
it handle a continuous stream of objects over a network?

By the way, is the website down?  http://www.castor.org/

While sequence of objects can be serialized to a stream, they can't be
deserialized.  The motivation for this comes from experience
with java serialization:
oos.writeInt(12345);
oos.writeObject("Today");
oos.writeObject(new Date());
and then...
int i = ois.readInt();
String today = (String) ois.readObject();
Date date = (Date) ois.readObject();
The error message for the following test case is:
Parsing Error : The markup in the document following the root element 
must
be well-formed.

public void testMarshalMultipleObjects() throws Exception
{
TestObject testObject1 = new TestObject();
testObject1.testString = "test one";
TestObject testObject2 = new TestObject();
testObject2.testString = "test two";
StringWriter stringWriter = new StringWriter();
Marshaller marshaller = new Marshaller(stringWriter);
marshaller.setSupressXMLDeclaration(true); //doesn't matter
marshaller.marshal(testObject1);
marshaller.marshal(testObject2);
StringReader stringReader = new StringReader(stringWriter.toString());
Unmarshaller unmarshaller = new Unmarshaller(TestObject.class);
TestObject newTestObject1 = (TestObject)
unmarshaller.unmarshal(stringReader);//fails
TestObject newTestObject2 = (TestObject)
unmarshaller.unmarshal(stringReader);
Assert.assertEquals(testObject1.testString, newTestObject1.testString);
Assert.assertEquals(testObject2.testString, newTestObject2.testString);
}
public class TestObject
{
public String testString;
public TestObject()
{
}
public String getTestString()
{
return testString;
}
public void setTestString(String testString)
{
this.testString = testString;
}
}
