addXsdModel

public static String[] addXsdModel(Resource resource,
 KnowledgeBuilder kbuilder,
 com.sun.tools.xjc.Options xjcOpts,
 String systemId)
                            throws IOException

Generates pojos for a given XSD using XJC and adds them to the specified KnowlegeBase.

 Options xjcOpts = new Options();
 xjcOpts.setSchemaLanguage( Language.XMLSCHEMA );
 KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

 String[] classNames = KnowledgeBuilderHelper.addXsdModel( ResourceFactory.newClassPathResource( "order.xsd",
                                                                                                 getClass() ),

                                                           "xsd" );
 

Parameters:

resource - The resource to the XSD model

kbuilder - the KnowledgeBuilder where the generated .class files will be placed

xjcOpts - XJC Options

systemId - XJC systemId

Returns:

Returns an array of class names that where generated by the XSD.

Throws:

IOException
