MessageAnand,

Another schema-oriented tool to check out in Java xmlbeans, which is an open-source tool in incubation in Apache.

http://xml.apache.org/xmlbeans

It allows you to compile any schema into Java classes.  It has the advantage that it supports 100% of W3C XML Schema (including things like type substitution and element substitution) and has a number of features to help you build valid instances.  It also has the ability to help you strictly validate parts your instance as you build it.

  Hi Anand:

   

  Have you considered using XDB features  in Oracle DB ?  Depending on system architecture for your application, XDB might be an option.  When you use XDB, you can validate during storage.

   

  Otherwise, all good parsers (Xerces, Oracle, etc..) support validation against schema on parsing. You have to make sure that you do - setValidationMode(true).

  Hello,

   

  the only tool that I know that validates automatically when generating XML is JAXB (http://java.sun.com/xml/jaxb/). But this supports only a subset of the W3C Schemas. You could also write your xml and validate if afterwards with a SAX parser (http://www.saxproject.org/). But if you are sure that you are writing valid xml, there is no need for extra validation.

   

  Kind regards,

  IsmaŽl

  Hello Everybody,

   

  My J2EE web application has to read data from an Oracle database and generate an XML which should confirm to a given XSD file. I can create this XML file using java to retrieve data from DB and write it to an XML using File I/O. 

   

  Is this the correct way to do it or should I be using some Free Utility code which will validate the XML file(against the given XSD) as it creates it?

   

  I was thinking that since I will be writing Java code to create the XML it will anyways comply with specified XSD.

   

  Thanks in advance.

   

  Regards,

  Anand
