Hi everyone. I just came across this thread and it addresses the exact same
problem I am having. Anne and Xinjun, I understand the different between
Document style and RPC style services. However, what I don't understand is
how to specify a serializer in the Axis client. Is there any documentation
on how to do this?
I tried adding the following code to my "XXXBindingStub" class:
qName = new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema";, "anyType");
cachedSerQNames.add(qName);
cls = org.w3c.dom.Document.class;
cachedSerClasses.add(cls);
cachedSerFactories.add(beansf);
cachedDeserFactories.add(beandf);
However, this leads to the error "Unable to create JavaBean of type
org.w3c.dom.Document. Missing default constructor? Error was:
java.lang.InstantiationException: org.w3c.dom.Document."
This makes perfect sense since there is no default constructor for
org.w3c.dom.Document. However, what do I do now?
Sincerely,
Matt Solnit
