Description

Prerequirements: before reproduce and workaround the issue need to apply the fix for problem with using several internal schemas. It is commited in the trunk:
https://github.com/apache/ode/commit/ccdba9fab2eb9821ab96f05a96dab65c27d3cb14

There is problem with schema capturing for wsdl that contains internal schemas and one imports another:

	<wsdl:types>
		<xsd:schema targetNamespace="http://ode/bpel/unit-test.wsdl">
			<xsd:import namespace="http://ode/bpel/import/types" />
			<xsd:simpleType name="dummy">
				<xsd:restriction base="d:dummyType" />
			</xsd:simpleType>
		</xsd:schema>
		<xsd:schema targetNamespace="http://ode/bpel/import/types">
			<xsd:simpleType name="dummyType">
				<xsd:restriction base="xsd:string" />
			</xsd:simpleType>
		</xsd:schema>
	</wsdl:types>

To workaround this problem it is enough to change schemas order(put "http://ode/bpel/import/types" on the top).
Bug is related to resolving entity in org.apache.ode.bpel.compiler.WsdlFinderXMLEntityResolver.resolveEntity(XMLResourceIdentifier).
This method searches imported schemas in the _internalSchemas map:
_internalSchemas.get(new URI(resourceIdentifier.getNamespace()))
This map is populated in org.apache.ode.bpel.compiler.WSDLRegistry.captureSchemas(Definition, ResourceFinder, URI). But since second(imported) schema is not put to map so "resolveEntity" returns null.
To fix the problem we need to populate _internalSchemas map before schema capturing.
Attached:

• HelloWorld2.zip that can be used to reproduce the issue;
• ODE.log where error can be found if DEBUG level is enabled for "org.apache.ode.utils.xsd" package;
• my fix "WSDLRegistry.zip\WSDLRegistry(my fix).java".
