Hi all,
I need some advice for the following.
0. I use WSDL2JAVA with XmlBean binding to generate the service side code
following the quickstartxmlbean example.
1. Our service related XMLBean types/element xsd are packaged in
XBean-packaged.jar in our .aar file under services.
2. Looks like when convert a derived type to XML, the code in
SchemaTypeSystemImpl(which is in WEB-INF/lib/xbean-2.2.0.jar) is trying to
load derived type info from XBean-packaged.jar. For example, it tried to
load a derived type
"schemaorg_apache_xmlbeans/type/http_3A_2F_2Fquickstart_2Esamples_2Fxsd_2F2007_2F01_2F01/FreeFormPolicyObject.xsb"
3. The problem is the class loader used by xbean-2.2.0.jar is the
WebappClassLoader, not the classloader from Axis service. So it cannot load
the resource!
4. I tried to put XBean-packaged.jar under WEB-INF/lib w or w/o removing
the Xbean-package.jar in .aar, but in both cases got ClassCastException
during
org.apache.xmlbeans.XmlBeans.getContextTypeLoader().parse()
I assume now the XBean-packaged.jar are needed both by the web service
code and xbean-2.2.0.jar. Any advice on how to make it work?
Thanks,
-Bo

org.apache.xmlbeans.impl.schema.SchemaTypeLoaderImpl's
findTypeRef (). This causes the derived type cannot be created properly with
the xsi:type attribute.

findTypeRef () not being populated correctly for derived type when deployed
as a service. This in turn was caused by typeSystemForComponent() in
findTypeRef() returning null. As comparison, the _typeCache is populated
correctly if I run it locally in a test program's main() and in this case
the typeSystemForComponent() is not null.

findTypeRef will return null. This will result in the changeType() call to

GetAddressesDocumentImpl.getAddressArray, I would expect
the array element should be of type USAddressImpl if instance is a US
address. This is not the case. For example, all elements in targetList
filled by find_all_element_users() are instances of AddressImpl not
USAddressImpl when the XML element is as follows:
