[jdom-interest] will use StringBuffer instead of String (was RE: [jdom-interest] org.jdom.Namespace not implementing Serializable?)

[Humphrey Sheil]

[changed subject]

Oops.  I should have mentioned that we'll use StringBuffer in the meantime
to work around this RMI limitation, i.e. pass around a StringBuffer and only
create a Document in the layer that will publish the XML directly to disk.

Thanks,

I should have traversed the entire object graph to find this.

I was hoping to avoid having to serialize the Document to a string.  The JDK
has imposed a hard 64k limit on the serialized form of a string (in
java.io.DataOutputStream), since it uses the first two bytes of the
underlying array to store the size of the array.  Any bigger and a
UTFDataFormatException will be thrown.

It's still an issue, there was a discussion about it, check the archives.

A Document contains references to Element, which in turn has references to
Namespace. For the object to be serialized all the objects it references
to must also be serializable.
	
Can I suggest that you serialize the document into a String and then send
that over the wire. The client can then create a JDOM object from the
String using the SAXBuilder class.
