I have servlet which uses utility packaged in .jar archive:<\/p>\n
@Override\npublic void init() throws ServletException {\n ...\n try (InputStream stream = getClass().getResourceAsStream(\"\/fileToParse.xml\")) {\n App.check(stream);\n } catch (Exception e) {\n throw new ServletException(e);\n }\n ...\n}\n<\/code><\/pre>\nThis utility takes xml file stream, performs validation against xsd schema and parses it:<\/p>\n
public class App {\n private static final String JAXP_SCHEMA_LANGUAGE = \"http:\/\/java.sun.com\/xml\/jaxp\/properties\/schemaLanguage\";\n private static final String W3C_XML_SCHEMA = \"http:\/\/www.w3.org\/2001\/XMLSchema\"; \n ... \n public static void check(InputStream stream) { \n SAXParserFactory spf = SAXParserFactory.newInstance();\n spf.setNamespaceAware(true);\n spf.setValidating(true);\n MyHandler handler = new MyHandler();\n try {\n SAXParser sp = spf.newSAXParser();\n sp.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);\n XMLReader rdr = sp.getXMLReader();\n rdr.setContentHandler(handler);\n rdr.setErrorHandler(new MyErrorHandler());\n rdr.parse(new InputSource(stream));\n }\n ...\n }\n ...\n}\n<\/code><\/pre>\nxsd file starts with:<\/p>\n

P.S. Sorry for my bad English<\/p>\n
UPD:<\/strong><\/p>\nI’m trying to add this property:<\/p>\n
