3.2. Dealing with schemas that are not referenced

Because of ambiguity in the XML Schema spec, some WSDLs are published that reference other schemas without specifying their locations. This happens most commonly with the reference to the schema for XML Schema, like this:

Location-less reference to a schema

<!-- notice there's no schemaLocation attribute -->
<xs:import namespace="http://www.w3.org/2001/XMLSchema" />

When you run wsimport with such a schema, this is what happens:

Error output from wsimport
$ wsimport  SecureConversation.wsdl
[ERROR] undefined element declaration 'xs:schema'
line 1 of

To fix this, two things need to be done:

  1. Run wsimport with the -b option and pass the URL/path of the actual schema (in the case of XML Schema, it's here. This is to provide the real resolvable schema for the missing schema.
  2. For the schema for Schema, potential name conflicts may arise. This was discussed here at length and a JAXB customization has been created to resolve such conflicts.

So your wsimport command will be:

Compiling a WSDL with XML Schema
$ wsimport -b  http://www.w3.org/2001/XMLSchema.xsd  -b  customization.xjb  SecureConversation.wsdl

You can do the same with NetBeans 5.5.1 by providing local copies of these schema and customization files. If you are facing this issue try it and let us know if you have any problems.
