Tom, you mention a complex type. I have a complex type i need to serialize that contains another complex type. Are there any examples on how to setup the serializer/deserializer for this either with BeanSerializer or with custom classes?

I have added some debug output to the serialize method of my custom Serializer and I have noticed that this method seems to be invoked twice for a single invocation of a web service method (I expect that the serializtion of my datatype to XML needs only to be done once to invoke the web service). I added a stack dump to the serialize method of my custom serializer and the result is that I got the following two stack dumps upon a single web service invocation java.lang.Exception: Stack trace at java.lang.Thread.dumpStack(Thread.java:1071) at com.mycompany.www.type.MyDataSer.serialize(Unknown Source) at org.apache.axis.encoding.SerializationContextImpl.serializeActual(Serializat ion ContextImpl.java:1229) at org.apache.axis.encoding.SerializationContextImpl.serialize(SerializationCon tex tImpl.java:750) at org.apache.axis.encoding.SerializationContextImpl.outputMultiRefs(Serializat ion ContextImpl.java:821) at org.apache.axis.message.SOAPBody.outputImpl(SOAPBody.java:144) at org.apache.axis.message.SOAPEnvelope.outputImpl(SOAPEnvelope.java:470) at org.apache.axis.message.MessageElement.output(MessageElement.java:1111) at org.apache.axis.client.Call.invoke(Call.java:2661) at org.apache.axis.client.Call.invoke(Call.java:2357) at org.apache.axis.client.Call.invoke(Call.java:2280) at org.apache.axis.client.Call.invoke(Call.java:1741) at com.mycompany.www.MyStub.testService(Unknown Source) at com.mycompany.www.Test.run(AbstractMessageHandler.java at java.lang.Thread.run(Thread.java:536) java.lang.Exception: Stack trace at java.lang.Thread.dumpStack(Thread.java:1071) at com.mycompany.www.type.MyDataSer.serialize(Unknown Source) at org.apache.axis.encoding.SerializationContextImpl.serializeActual(Serializat ion ContextImpl.java:1229) at org.apache.axis.encoding.SerializationContextImpl.serialize(SerializationCon tex tImpl.java:750) at org.apache.axis.encoding.SerializationContextImpl.outputMultiRefs(Serializat ion ContextImpl.java:821) at org.apache.axis.message.SOAPBody.outputImpl(SOAPBody.java:144) at org.apache.axis.message.SOAPEnvelope.outputImpl(SOAPEnvelope.java:470) at org.apache.axis.message.MessageElement.output(MessageElement.java:1111) at org.apache.axis.SOAPPart.writeTo(SOAPPart.java:268) at org.apache.axis.SOAPPart.getAsString(SOAPPart.java:499) at org.apache.axis.SOAPPart.getAsBytes(SOAPPart.java:386) at org.apache.axis.Message.getContentType(Message.java:465) at org.apache.axis.transport.http.HTTPSender.writeToSocket(HTTPSender.java:307) at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:87) at org.apache.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java: 32) at org.apache.axis.SimpleChain.doVisiting(SimpleChain.java:118) at org.apache.axis.SimpleChain.invoke(SimpleChain.java:83) at org.apache.axis.client.AxisClient.invoke(AxisClient.java:144) at org.apache.axis.client.Call.invokeEngine(Call.java:2688) at org.apache.axis.client.Call.invoke(Call.java:2671) at org.apache.axis.client.Call.invoke(Call.java:2357) at org.apache.axis.client.Call.invoke(Call.java:2280) at org.apache.axis.client.Call.invoke(Call.java:1741) at com.mycompany.www.MyStub.testService(Unknown Source) at com.mycompany.www.Test.run(AbstractMessageHandler.java :89) at java.lang.Thread.run(Thread.java:536) Does anyone have any idea why this happens. Is there somthing in the internals of Axis that leads to this behavious. My web service invocation is successful so its not causing any problems for me but I am just curious as to why this might occur.
