Fix XSD generation from xml instance file

XMLWordPrintable

    • Sprint 2, 8.0.0 - Sprint 1, 8.0.0 - CR1

      2 tests are failing (set to @Ignore currently):

      • org.jboss.tools.fuse.transformation.model.xml.XmlModelGeneratorIT.generateFromInstance()
      • org.jboss.tools.fuse.transformation.model.xml.XmlModelGeneratorIT.generateFromInstanceWithMultipleNamespaces()

      The tests reveals real issue. it doesn't either in the UI.

      The error is:

      Current investigation:

      • the library is playing with some classloaders (not a good thign in OSGi world)
      • the library used is 2.3.0, the last one is 2.6.0 released in 2012 (but not provided as OSGi version)
      • the library is based on an Apache project which has been retired since 05/2014
      • not found viable alternatives:
        • xsd-gen: maintained by a single guy and with no license
        • xmlspy from Oxygen with commercial license
        • trang with last release from 2008
        • jaxb and xerces seem not providing this kind of feature
      • I cannot found the SchemaDocument source code in which the error occured
      • decompilation leads to this strange line 
        (SchemaType)XmlBeans.typeSystemForClassLoader(
	(1.class$org$apache$xmlbeans$impl$xb$xsdschema$SchemaDocument == null ?
		(1.class$org$apache$xmlbeans$impl$xb$xsdschema$SchemaDocument = 1.class$("org.apache.xmlbeans.impl.xb.xsdschema.SchemaDocument"))
		: 1.class$org$apache$xmlbeans$impl$xb$xsdschema$SchemaDocument).getClassLoader()
	, "schemaorg_apache_xmlbeans.system.sXMLSCHEMA")
.resolveHandle("schema0782doctype");

        which results with the EquinoxClassloader of the plugin org.apache.xmlbeans trying to load the class: schemaorg_apache_xmlbeans.system.sXMLSCHEMA.TypeSystemHolder and in the binary plugin in this folder there are only xsb files
