XmlSchemaElement elements in schema obtained from ServiceClient have incorrect
(null) SchemaType
------------------------------------------------------------------------------------------------
Key: AXIS2-4013
URL: https://issues.apache.org/jira/browse/AXIS2-4013
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: 1.4
Environment: OS: Windows XP
IDE: IBM Rational Application Developer 7.0.0.6
Java: 1.5
Server: Websphere App Server 6.1.17
Reporter: Darin DeFer
I am trying to prototype stubless WS invokation. The WSDLs in our web services
contain multiple namespaces. The schema produced by ServiceClient contains a
null SchemaType for XmlSchemaElements for all but one NameSpace. It appears
that the multiple namespaces prevent the schema generator from properly
identifying all complex types. We can't use Axis2 to generate dynamic payloads
if we can't drill down all the simpleTypes. I cannot find a workaround for
this - seems there's no way to get the details for the impacted elements.
The following is logged when attempting to traverse schema all the way down to
simple schema elements.
