org.xml.sax.SAXException: FWK005 parse may not be called while parsing.Above Error occurs because you might have SchemaFactory instance , which is shared by multiple threads. Like declaring it at class level , and using it in methods .
private SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);The SchemaFactory is not thread safe . It should always be initialized and accessed in local scope. So whenever you need SchemaFactory instance , just create it locally instead of using it at instance level. Post Comments And Suggestions !!
