No Serializer for java.util.TreeSet??

[Johannes Fiala]

Hi there,

I've added a java.util.TreeSet (available since JDK 1.2) to my classes transferred via SOAP and now I get the following error:

Generated fault: [Attributes={}] [faultCode=SOAP-ENV:Server] [faultString=java.l
ang.IllegalArgumentException: No Serializer found to serialize a 'java.util.Tree
Set' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.] [faultAc
torURI=/Signon/servlet/rpcrouter]

java.util.TreeSet implements Serializable, so there should be no problem, but there is one!

How can I update the serializers of Apache SOAP to support java.util.TreeSet?

thx alot
