Hello Deepak, when I try to use catalog.xml and catalog.xsd, i get the following errors. Can you please give me some idea on why this error could be coming: org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document '<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="catalog"> <xsd:complexType> <xsd:sequence> <xsd:element ref="journal" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> <xsd:attribute name="title" type="xsd:string"/> <xsd:attribute name="publisher" type="xsd:string"/> </xsd:complexType> </xsd:element> <xsd:element name="journal"> <xsd:complexType> <xsd:sequence> <xsd:element ref="article" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> <xsd:attribute name="date" type="xsd:string"/> </xsd:complexType> </xsd:element> <xsd:element name="article"> <xsd:complexType> <xsd:sequence> <xsd:element name="title" type="xsd:string"/> <xsd:element ref="author" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name="author" type="xsd:string"/></xsd:schema>', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

  Is the schema specified in the XML document?
  Please specify schema in XML document withn noNamespaceSchemaLocation attribute.

  Now I specified specifying noNamespaceSchemaLocation attribute. Now my xml looks like this. Both xml and xsd are WSAD workspace, so I cannot give file path. There are in the same location. So, do i need to mention any relative path?
  <?xml version="1.0" encoding="utf-8" ?>
  <catalog xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="catalog.xsd" >

  Thanks for the quick reply Deepak. I will try what you advised.
  Actually, I was reading xml and xsd from file system and passing them as String. Now I am passing them as InputStream. Now I am getting these errors. Any idea?
