[jgrapht-users] XML encoding of DirectedWeightedMultigraph

[Petr H. <ho...@ic...>]

Hi,

we've recenlty encountered a problem with encoding DirectedWeightedMultigraph
using XMLEncoder. Basically, for XMLEncoder to work, the object needs to
be Java Bean and implement Serializable. Does anybody has a clue why
it shouldn't work on DirectedWeightedMultigraph?

When attempting to serialize, I get the following execeptions:

java.lang.InstantiationException: org.jgrapht.graph.DirectedWeightedMultigraph
Continuing ...
java.lang.Exception: XMLEncoder: discarding statement
XMLEncoder.writeObject(DirectedWeightedMultigraph);
Continuing ...

TIA,
Petr
