-----------------------------------------------

David,
this probably is some unfortunate interaction between JBuilder and XmlBeans. The way we designed our Java binding, it binds Schema types to interfaces backed by implementation classes without an empty constructor. As you can imagine, it would be a pretty big deal to change this 180degrees to classes with empty constructor. Not to say that it's never going to happen, but you should not look for it in the near future. So this can't be filed as a "bug".
On the other hand, a lot of people are successfully using XmlBeans with WebLogic 8.1. I know this for a fact and there are threads on user@xmlbeans.apache.org discussing this; so you should refer to these threads and to the WebLogic documentation, because it can be done.

> Hi,
> I am working with XmlBeans in Jbuilder and have created a project that contains a couple of EJBs that use XmlBeans to compile and manipulate a couple of XSD Schema files.  The application works fine when deployed to Weblogic as an EJB, however when I configure the project as a Web Service and rebuild I get the following error:
> [servicegen] weblogic.xml.schema.binding.BindingException: Invalid class received: interface com.bt.sas.SasSendDocument loaded from file:/D:/CLASSPATH/XmlBeanProject/xmlTypesSasSend.jar!/com/bt/sas/SasSendDocument.class.  All classes that will be serialized or deserialized must be non-interface, non-abstract classes that provide a public default constructor
> As I hinted above I am instantiating the interface "SasSendDocument.class" in my JBuilder project and can deploy and run the application but when I try and create a web service from the project it starts complaining about the fact that I am using an interface.  XmlBeans "scomp" also generated a SasSendDocumentImpl.class that I have tried to use to overcome this problem (althoughin WLWorkshop I have always used the XmlBeanDocument object), but I then get the following error:
> [servicegen] weblogic.xml.schema.binding.BindingException: No default constructor was found for class com.bt.sas.xml.impl.SasResultDocumentImpl loaded from file:/D:/Classpath/SasReturnSrc.jar!/com/bt/sas/xml/impl/SasResultDocumentImpl.class.All classes that will be serialized or deserialized must be non-interface, non-abstract classes that provide a public default constructor - with nested 
> Here it seems to be complaining that the class has no default constructor.  However, these classes are auto-generated by XmlBeans for me and I don't believe I should have to tinker with the source and recompile.  Anyway, even if I do change the class I cannot update the .xsb files which were produced by the XmlBeans compiler.
