Hi all, I have just joined this list and have searched the archives for my answer, but I still need some help.
What I want: Someone to explain the deployment descriptor settings to me, specifically the ones dealing with mappings for Serialisers/Deserialisers. I have used a test service (details below) to send a hashtable from the Apache 2.2 SOAP Server to a perl SOAP::Lite client. This works OK. I then added my custom Object (Test.java) to the returned hashtable, and tried to register a mapping for Apache Soap to serialise this Object. This is where I think I have made a mistake. I don't understand the xmlns and the qname attributes - what they do or what to set them to. When I run my client I get an error java.lang.IllegalArgumentException: No Serializer found to serialize a 'onjava.Test' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/' It looks like the error is on the java server side when it is trying to flatten the Object to XML. I would really appreciate any help on this one, Thanks in advance.
